Mental Health Solicitors.

Mental health and mental capacity law concerns the rights, care, treatment, and protection of people who may have a mental disorder or be unable to make certain decisions for themselves.

A specialist mental health solicitor may advise patients, relatives, carers, attorneys, deputies and professionals. They can help challenge detention or compulsory treatment, resolve disputes about care and residence, protect the rights of people who lack capacity and provide representation before tribunals and the Court of Protection.

Mental health law and mental capacity law are related but distinct. The Mental Health Act principally concerns the assessment, detention and compulsory treatment of people with a mental disorder. The Mental Capacity Act concerns decision-making for people who lack the capacity to make a particular decision at the relevant time.

This guide principally covers the law in England and Wales. Scotland and Northern Ireland have separate legislation and procedures.

The Mental Health Act

The Mental Health Act 1983 provides the principal legal framework for assessing, detaining and treating people with a mental disorder in England and Wales. It also governs community treatment orders, guardianship, transfers from prison, the rights of nearest relatives, and applications to the Mental Health Tribunal.

The Act broadly defines mental disorder as any disorder or disability of the mind.

A diagnosis by itself does not automatically justify detention. The legal requirements of the particular section must also be satisfied.

Depending on the power used, professionals may need to establish that:

• the person has a mental disorder of a nature or degree warranting detention;
• detention is necessary for the person's health or safety or for the protection of others;
• appropriate medical treatment is available;
• assessment or treatment cannot safely or appropriately be provided voluntarily; and
• the required medical recommendations and application have been completed lawfully.

The Mental Health Act 2025

The Mental Health Act 2025 received Royal Assent in December 2025 and will make substantial changes to the Mental Health Act 1983. However, most of those reforms are not yet operating and will be introduced in stages through commencement regulations.

The current legal position should therefore be checked carefully. A provision appearing in the 2025 Act cannot necessarily be relied upon until it has formally come into force.

Informal and Detained Patients

Informal Patients

An informal or voluntary patient agrees to admission and treatment. An informal patient is generally entitled to leave the hospital. However, the Mental Health Act contains short-term holding powers that may be used in qualifying circumstances. At the same time, an assessment is arranged.

A patient should not be deemed voluntary merely because they do not actively object.

Professionals must consider whether the patient has the capacity to consent, whether consent is genuine and whether the person is effectively prevented from leaving.

Detained Patients

A detained patient, commonly described as being "sectioned", is held under a specific provision of the Mental Health Act. The section determines the purpose and maximum initial duration of detention, the available treatment powers, and when the patient can apply to a tribunal.

A patient should be informed of:

• the section under which they are detained;
• the reasons for detention;
• how long the section may last;
• their rights to legal advice and advocacy;
• their rights to apply to the tribunal;
• the role of the hospital managers;
• their rights concerning treatment; and
• how to make a complaint.

Detention for Assessment

Section 2 of the Mental Health Act permits detention in hospital for assessment and, where appropriate, initial treatment. It can generally last for up to 28 days. It cannot simply be renewed as another section 2.

An application will normally be based on recommendations from two doctors and made by an approved mental health professional or, less commonly, the patient's nearest relative.

A section 2 patient has a short period in which to apply to the First-tier Tribunal. Immediate legal advice is therefore advisable.

Detention for Treatment

Section 3 permits detention for medical treatment where the statutory conditions are met. It can initially last for up to six months and may then be renewed for further periods.

Before an approved mental health professional makes a section 3 application, the patient's nearest relative will normally be consulted where reasonably practicable. The application generally cannot proceed if the nearest relative makes a valid objection, unless displacement proceedings or another lawful route is used.

A detained person may apply to the tribunal during the periods specified by the Act. The hospital managers also have the power to consider discharge.

Emergency and Holding Powers

The Mental Health Act contains several powers that can be used for short periods in urgent situations.

Emergency Admission

Section 4 may permit emergency admission for assessment based on a single medical recommendation when waiting for a second recommendation would cause an undesirable delay. It can generally last for up to 72 hours.

Nurses' Holding Power

A prescribed nurse may temporarily prevent an informal inpatient from leaving where the statutory requirements are met. Medical assessment is required.

Doctors' Holding Power

A doctor or approved clinician may use temporary holding power in relation to an informal inpatient when an application for detention is to be considered.

Holding powers should not be used merely for administrative convenience. Their requirements and time limits must be followed strictly.

Police Powers and Places of Safety

Police officers have powers under sections 135 and 136 of the Mental Health Act to remove a person or take them to a place of safety in specified circumstances.

Section 135 generally requires a warrant and may be used to enter private premises. Section 136 may apply where a person appears to have a mental disorder and requires immediate care or control in a place to which the public has access.

The person may be detained temporarily for assessment and arrangements for treatment or care. The power is not a criminal arrest, although police involvement may be distressing, and the person retains legal rights.

Compulsory Medical Treatment

The Mental Health Act allows certain treatment for mental disorder to be given without thepatient'ss consent where the statutory requirements are met. However, compulsory treatment is not unlimited.

Different rules apply depending on:

• the type of treatment;
• the section under which the patient is detained;
• how long treatment has continued;
• whether the patient has capacity;
• whether the patient consents;
• whether a second-opinion appointed doctor is required; and
• whether the treatment is immediately necessary.

Some particularly serious treatments require additional safeguards or cannot be given without valid consent except in narrowly defined circumstances.

A solicitor can advise where a patient or family disputes the lawfulness of treatment, the consent process or compliance with statutory safeguards.

Community Treatment Orders

A community treatment order, or CTO, allows certain patients detained for treatment to leave hospital while remaining subject to the Mental Health Act in the community.

A CTO may include conditions concerning matters such as residence, attendance at treatment, and access to assessment. The patient can be recalled to the hospital where the legal criteria are met.

Following recall, the CTO may continue, the patient may return to the community, or the order may be revoked so that the person is again detained for treatment.

A patient subject to a CTO may apply to the First-tier Tribunal within the applicable statutory periods. The nearest relative may also have relevant rights.

Guardianship

Guardianship under the Mental Health Act is a community-based arrangement intended to support aperson'ss welfare without detaining them in hospital.

A guardian may have powers concerning:

• where the person must live;
• attendance for medical treatment, occupation, education or training; and
• access by specified professionals.

Guardianship does not generally authorise compulsory medical treatment or permit the guardian to detain the person in a particular placement.

The Nearest Relative

The nearest relative is a specific legal role under the Mental Health Act. It is not necessarily the same person as the patient's next of kin, emergency contact or closest family member.

The Act uses a statutory order of relatives to identify who holds the role, subject to rules concerning age, residence, relationships and other circumstances.

Rights of the Nearest Relative

Depending on the patient's section, the nearest relative may have rights to:

• receive information;
• be consulted about a section 3 application;
• object to certain detention applications;
• request an assessment;
• apply for admission or guardianship;
• order discharge in specified circumstances;
• apply to the Mental Health Tribunal; and
• be informed about discharge or transfer.

The nearest relative's right to order discharge is subject to procedures allowing the responsible clinician to prevent discharge where the statutory risk test is met.

Displacement of the Nearest Relative

The county court can appoint another person to act as nearest relative where a statutory ground is established. This is commonly called displacement.

An application may be made where, for example, the existing nearest relative:

• is unable to act because of illness or another reason;
• unreasonably objects to an application for admission or guardianship;
• has exercised or is likely to exercise discharge powers without proper regard to the patient's welfare or public safety;
• is otherwise unsuitable to act; or
• cannot be identified or located.

The patient may also be able to apply for displacement in qualifying circumstances. Specialist advice is advisable because the outcome can significantly affect detention and discharge rights.

The Mental Health Tribunal

The First-tier Tribunal (Mental Health) is an independent judicial body. It considers applications and referrals concerning detained patients, community treatment orders, guardianship and conditional discharge.

The tribunal is part of the Health, Education and Social Care Chamber. It is commonly composed of a tribunal judge, a medical member, and a specialist lay member.

What Can the Tribunal Decide?

The tribunal can consider whether the statutory criteria for continued detention or supervision remain satisfied.

Depending on the patient's legal status, it may:

• direct discharge;
• recommend leave, transfer or another form of care;
• discharge a community treatment order;
• discharge guardianship;
• grant or vary a conditional discharge; or
• decide that the existing legal status should continue.

Preparing for a Tribunal Hearing

A mental health solicitor can:

• meet the patient and take instructions;
• explain the legal test for discharge;
• obtain and review hospital reports and medical records;
• consider commissioning independent medical evidence;
• identify suitable community care or accommodation proposals;
• question the responsible clinician, social worker and nursing witnesses;
• present legal submissions; and
• challenge inaccurate or unsupported evidence.

The patient can usually attend and participate, subject to the tribunal's procedural decisions and the patient's wishes and condition.

Appealing a Tribunal Decision

A tribunal decision cannot be appealed merely because the patient disagrees with it. Permission to appeal generally requires an arguable error of law.

An application for permission is normally made first to the First-tier Tribunal. If permission is refused, a further application may be made to the Upper Tribunal within the applicable time limit.

Legal Aid for Mental Health Cases

Legal aid may be available for advice and representation in qualifying mental health matters. Representation before the Mental Health Tribunal is commonly available without a financial means test for eligible detained or supervised patients.

Different eligibility rules may apply to Court of Protection proceedings, community care disputes, judicial review and other cases.

A solicitor with a mental health legal-aid contract can explain whether the case qualifies and what evidence is required.

Independent Mental Health Advocates

Certain patients detained or treated under the Mental Health Act are entitled to support from an independent mental health advocate, commonly called an IMHA.

An IMHA can help a patient understand:

• their rights under the Mental Health Act;
• the reasons for detention;
• the treatment being proposed;
• how to make a complaint;
• how to contact a solicitor; and
• how to participate in meetings and care planning.

An advocate does not replace a solicitor and does not provide legal representation at a tribunal.

Section 117 Aftercare

Some patients who have been detained for treatment become entitled to aftercare under section 117 of the Mental Health Act when they leave hospital.

The duty is usually shared by the relevant NHS body and local authority. Aftercare must address needs arising from or related to the person's mental disorder and reduce the risk of deterioration or readmission.

It may include:

• supported accommodation;
• community mental health services;
• social care;
• therapy or psychological support;
• support with medication;
• assistance with employment or daily living; and
• other services connected with the person's mental health needs.

Qualifying section 117 aftercare cannot ordinarily be charged for. Disputes may arise about responsibility, the services required, accommodation charges or whether the duty can lawfully be ended.

Patients in Prison and Transfers to Hospital

A prisoner with a mental disorder may be transferred to hospital under the Mental Health Act where the statutory conditions are met.

A solicitor may assist with:

• requests for psychiatric assessment;
• delays in transfer;
• representations to prison healthcare services;
• hospital transfer directions;
• restricted-patient status;
• tribunal proceedings;
• recall or conditional discharge; and
• care and release planning.

Transferred prisoners may remain subject to criminal sentences and Ministry of Justice controls, as well as mental health legislation.

The Mental Capacity Act 2005

The Mental Capacity Act 2005 applies to people aged 16 and over in England and Wales who may lack the capacity to make a particular decision.

Capacity is decision-specific and time-specific. A person may be able to decide one matter but not another, or may lack capacity temporarily and recover it later.

The Five Statutory Principles

The Act is based on five principles:

• a person must be assumed to have capacity unless it is established otherwise;
• a person must not be treated as unable to decide until all practicable support has been provided without success;
• a person is not to be treated as lacking capacity merely because they make an unwise decision;
• an act or decision made for someone lacking capacity must be in their best interests; and
• the option chosen should interfere as little as reasonably possible with the person's rights and freedom.

The Test for Mental Capacity

A person lacks capacity in relation to a matter if, because of an impairment or disturbance in the functioning of the mind or brain, they are unable to make the decision when it needs to be made.

A person may be unable to decide if they cannot:

• understand the relevant information;
• retain it long enough to make the decision;
• use or weigh it as part of the decision-making process; or
• communicate the decision by any means.

A diagnosis of dementia, learning disability, brain injury or mental illness does not automatically prove incapacity.

Best-Interests Decisions

Where a person lacks capacity, any decision made for them must be in their best interests unless a valid alternative authority applies.

The decision-maker should consider:

• all relevant circumstances;
• whether capacity may return;
• the person's past and present wishes and feelings;
• any written statement made while the person had capacity;
• the person's beliefs and values;
• the views of family members, carers, attorneys and deputies;
• whether the person can participate in the decision; and
• whether a less restrictive option is available.

Best interests are not determined solely by what professionals or relatives regard as sensible. The individual's own wishes and values must be given proper consideration.

The Court of Protection

The Court of Protection makes decisions and declarations regarding people who lack the capacity to make certain decisions for themselves.

The Court may consider disputes concerning:

• medical treatment;
• residence and care arrangements;
• contact with relatives or other people;
• deprivation of liberty;
• property and financial affairs;
• gifts and transactions;
• statutory wills;
• the validity or operation of a lasting power of attorney;
• the appointment or removal of a deputy; and
• whether a person has capacity to make a particular decision.

Health and Welfare Cases

The Court may be asked to decide where a person should live, what care they should receive, whether contact should take place and whether proposed medical treatment is lawful and in their best interests.

Serious medical cases may concern:

• life-sustaining treatment;
• clinically assisted nutrition and hydration;
• major surgery;
• organ or tissue donation;
• sterilisation or contraception;
• obstetric treatment;
• experimental treatment; and
• disagreement between clinicians and family members.

Urgent applications can be made where treatment or immediate protection cannot await an ordinary hearing.

Residence and Contact Disputes

The Court of Protection may resolve disputes about whether a person should live at home, in supported accommodation, in a care home or elsewhere.

It may also decide whether contact with a relative, partner, friend or another person is in the individual's best interests. Restrictions on contact must be justified, proportionate and kept under review.

Children and Young People

The Mental Capacity Act generally applies from age 16. However, cases involving children and young people may also engage parental responsibility, the Children Act, the inherent jurisdiction of the High Court and specialist deprivation-of-liberty procedures.

< p> The Court and legal framework will depend on the young person's age, capacity, circumstances and the decision in dispute.

Deputyship

The Court of Protection may appoint a deputy to make specified decisions for a person who lacks capacity.

Property and Financial Affairs Deputies

A property and financial affairs deputy may be authorised to manage matters such as:

• bank accounts;
• benefits and income;
• bills and debts;
• investments;
• property maintenance;
• buying or selling property; and
• care-related expenditure.

The deputy's authority is limited by the court order. Some decisions, including substantial gifts or unusual transactions, may require a further application.

Health and Welfare Deputies

Health and welfare deputies are appointed less coCourty. The Court usually prefers to decide serious welfare disputes as they arise rather than to grant one person broad, continuing powers.

A deputy must act within the order, follow the Mental Capacity Act principles, keep proper records and report to the Office of the Public Guardian.

Lasting Powers of Attorney

A person who has capacity can appoint trusted people as attorneys under a lasting power of attorney.

There are two types:

• property and financial affairs; and
• health and welfare.

A health and welfare attorney can generally act only when the donor lacks capacity to make the relevant decision. Authority over life-sustaining treatment must be granted expressly in the document.

A property and financial affairs attorney may be authorised to act while the donor still has capacity, depending on the donor's instructions.

Disputes about an attorney's conduct, the validity of an appointment or safeguarding concerns may be referred to the Office of the Public Guardian or the Court of Protection.

Advance Decisions to Refuse Treatment

An advance decision to refuse treatment, sometimes called an advance directive or living will, allows an adult with capacity to refuse specified medical treatment for a future time when they may lack capacity to decide.

For an advance decision to be legally effective, it must be valid and applicable to the particular treatment and circumstances.

An advance decision refusing life-sustaining treatment must satisfy additional formalities. It must generally:

• be in writing;
• be signed by the person making it or by another person at their direction;
• be witnessed;
• state clearly that it applies even if life is at risk; and
• identify the treatment and circumstances with sufficient clarity.

An advance decision can refuse treatment but cannot require clinicians to provide treatment they consider clinically inappropriate.

Specialist advice may be helpful where complex treatment is involved or where there may be interaction with a lasting power of attorney or compulsory treatment under the Mental Health Act.

Advance Statements

An advance statement records a person's wishes, preferences, beliefs and values concerning future care and treatment.

It may cover:

• preferred living arrangements;
• diet and daily routines;
• religious or cultural practices;
• people to be consulted;
• preferred hospitals or care settings;
• treatment preferences; and
• care of pets or personal belongings.

An advance statement is not legally binding in the same way as a valid advance decision refusing treatment. Still, it must be considered when decisions are made in the person's best interests.

Independent Mental Capacity Advocates

An independent mental capacity advocate, known as an IMCA, may be required in specified cases where a person lacks capacity and has no appropriate family member or friend to consult.

IMCAs may be involved in decisions about:

• serious medical treatment;
• long-term changes of accommodation;
• care reviews;
• adult safeguarding; and
• deprivation-of-liberty arrangements.

The advocate represents the person's interests and helps ensure their wishes, feelings and rights are considered.

Deprivation of Liberty

A person may be deprived of their liberty where the arrangements for their care impose sufficiently significant restrictions, and the person has not validly consented to those arrangements.

Whether particular care arrangements amount to a deprivation of liberty is fact-sensitive. The legal position was clarified by a Supreme Court judgment delivered on 2 June 2026, which addressed the role of valid consent and confirmed that compliance alone does not necessarily establish consent.

Care providers and public bodies must now consider carefully what the person actually understands and agrees to, rather than assuming that a person who does not resist has consented.

Deprivation of Liberty Safeguards

The Deprivation of Liberty Safeguards, commonly known as DoLS, remain the principal statutory authorisation process for adults aged 18 or over who lack capacity to consent to care arrangements in a hospital or registered care home.

The care home or hospital applies for authorisation, and the supervisory body arranges the statutory assessments.

The assessments consider matters including:

• the person’s age;
• mental health;
• mental capacity;
• whether the arrangements amount to a deprivation of liberty;
• whether the arrangements are necessary and proportionate;
• whether they are in the person’s best interests; and
• whether another legal authority conflicts with the proposed arrangements.

An authorisation may include conditions and must last no longer than the permitted period.

Community and Other Settings

DoLS does not generally authorise a deprivation of liberty in supported living, an individual's own home, or other community settings. In those cases, an application to the Court of Protection may be required.

The Court may also need to authorise arrangements for people under 18, depending on their age, capacity and circumstances.

Challenging a DoLS Authorisation

The person or their representative can apply to the Court of Protection under section 21A of the Mental Capacity Act to challenge matters including:

• whether the person lacks capacity;
• whether the arrangements amount to a deprivation of liberty;
• whether the qualifying requirements are met;
• whether the placement is in the person's best interests;
• the duration of the authorisation; and
• the conditions attached to it.

Where a person persistently objects to the placement or restrictions, those responsible for their care should ensure that access to legal advice and the Court is practical and effective.

Liberty Protection Safeguards

Legislation was passed to replace DoLS with the Liberty Protection Safeguards. However, that replacement system has not yet been implemented.

The Government announced a further consultation during 2026. Until new arrangements are formally brought into force, DoLS continues to apply in hospitals and care homes, with Court of Protection authorisation generally required in other settings.

Medical Treatment Disputes

Disputes may arise between clinicians, patients and families about whether treatment should be provided, withheld or withdrawn.

The legal issues may include:

• whether the patient has capacity;
• whether consent is valid;
• whether an advance decision applies;
• whether an attorney or deputy has authority;
• whether treatment is in the patient's best interests;
• whether the Mental Health Act authorises treatment;
• whether the proposed treatment is clinically appropriate; and
• whether urgent court approval is required.

In serious or finely balanced cases, an application to the Court of Protection may be necessary before treatment proceeds or is withdrawn.

Access to Health and Social Care Records

Relatives and carers do not automatically have an unrestricted right to see another adult's medical or social care records.

Access may depend on:

• the person's consent;
• whether an attorney or deputy has relevant authority;
• whether disclosure is necessary and in the person's best interests;
• data protection and confidentiality duties;
• the rights of third parties; and
• whether court proceedings are underway.

A lack of capacity does not make confidential records freely available to family members. However, professionals should not use confidentiality as a reason to ignore relevant information supplied by relatives or carers.

A solicitor can advise on requests for disclosure, subject access, Court of Protection disclosure orders and complaints concerning unjustified refusal.

Care and Support Disputes

Mental health solicitors may also advise on community care and public law disputes concerning:

• care needs assessments;
• care and support plans;
• withdrawal or reduction of services;
• residential and supported accommodation;
• continuing healthcare funding;
• section 117 aftercare;
• personal budgets and direct payments;
• safeguarding decisions;
• closure of care homes or day centres;
• changes of placement; and
• failures to provide suitable services.

The lawfulness of closing a particular facility will depend on matters including consultation, equality duties, assessment of individual needs, alternative provision and whether the public authority has acted rationally and fairly.

Urgent judicial review proceedings may be possible where an unlawful decision by a public body creates immediate harm.

Deaths in Psychiatric Care

Families may require specialist advice following the death of a person in a psychiatric hospital, care placement, prison or while receiving community mental health services.

A solicitor may assist with:

• obtaining medical and care records;
• participating in an inquest;
• requesting an Article 2 inquest where appropriate;
• questioning witnesses;
• investigating suicide-prevention and observation procedures;
• examining medication and discharge planning;
• considering safeguarding and risk assessments;
• dealing with internal investigations;
• making a complaint; and
• considering a civil claim.

Where the State may have failed to protect life, the inquest may be required to examine the wider circumstances in which the death occurred rather than only the immediate medical cause.

Inquiries and Investigations into Failures of Care

Solicitors may represent patients, families, employees, or professionals in inquiries and investigations into alleged failures in mental health care.

These may include:

• NHS investigations;
• safeguarding enquiries;
• professional disciplinary proceedings;
• Care Quality Commission investigations;
• ombudsman complaints;
• independent inquiries;
• public inquiries;
• inquests; and
• civil or criminal proceedings.

The appropriate response will depend on the seriousness of the allegation, the client's role, and whether legal or professional consequences may follow.

Complaints about Mental Health and Social Care

A patient or family member may be able to complain to the relevant NHS body, hospital, local authority, care provider or regulator.

A complaint may concern:

• unlawful detention;
• treatment without proper authority;
• poor care;
• failure to involve the patient or family;
• discrimination;
• medication;
• restraint or seclusion;
• privacy and dignity;
• discharge planning;
• loss of possessions;
• confidentiality; or
• failure to investigate a serious incident.

Complaints procedures do not replace urgent legal action where a patient is unlawfully detained, treatment is imminent or a person is at immediate risk.

Judicial Review and Human Rights

Judicial review allows the courts to examine the lawfulness of decisions made by public bodies. It may be relevant where an NHS body, local authority, hospital or other public authority has acted unlawfully, irrationally or unfairly.

Mental health and capacity cases may also engage rights under the European Convention on Human Rights, including:

• the right to life;
• freedom from inhuman or degrading treatment;
• the right to liberty;
• the right to a fair hearing;
• respect for private and family life; and
• protection from discrimination.

Judicial review claims are subject to short time limits and must generally be brought promptly.

How a Mental Health Solicitor Can Help

A specialist solicitor may assist with:

• challenging detention under the Mental Health Act;
• representation before the First-tier Tribunal;
• appeals involving the Upper Tribunal;
• community treatment orders and guardianship;
• nearest-relative rights and displacement proceedings;
• hospital managers’ hearings;
• compulsory treatment disputes;
• transfers from prison to hospital;
• section 117 aftercare;
• mental capacity assessments;
• Court of Protection proceedings;
• medical treatment disputes;
• residence, care and contact cases;
• deputyship and lasting powers of attorney;

• access to records;
• inquests and deaths in psychiatric care;
• complaints and investigations;
• judicial review; and
• human rights claims.
