What is this right?
This page covers mental health detention and treatment in England and Wales under the Mental Health Act 1983 — the legislation, with all its 2007 amendments, that governs "sectioning." Wales sits alongside England under the same Act, with extra procedural rules under the Mental Health (Wales) Measure 2010.
The MHA 1983 sets the criteria for compulsory admission and treatment of someone with a mental disorder. The sections most often invoked:
- Section 2: detention for assessment — up to 28 days. Requires recommendations from 2 doctors and an application by an Approved Mental Health Professional (AMHP) or the nearest relative.
- Section 3: detention for treatment — up to 6 months, renewable. Same application route plus a written treatment plan.
- Section 5: doctor's or nurse's holding power to keep a voluntary inpatient pending assessment — 72 hours (doctor) / 6 hours (nurse).
- Section 136: police power to take someone in a public place to a place of safety if they appear to have a mental disorder — up to 24 hours.
If you're detained, the law guarantees:
- An Independent Mental Health Advocate (IMHA)
- Appeal to the Mental Health Tribunal
- The least restrictive treatment compatible with your care
Different jurisdictions: Scotland operates under the Mental Health (Care and Treatment) (Scotland) Act 2003 — see the Scotland leaf. Northern Ireland runs the Mental Health (Northern Ireland) Order 1986 — see the Northern Ireland leaf. Wales is covered under MHA 1983 plus the Wales Measure 2010 — see the Wales leaf.
When does it apply?
- You can only be sectioned if you have a mental disorder of a nature or degree that warrants detention, and detention is necessary for your own health or safety or the protection of others.
- Voluntary patients ("informal patients") can leave hospital at any time — you cannot be prevented from leaving unless you are then formally sectioned.
- Your nearest relative has the right to apply for your discharge (though the responsible clinician can block this with a "barring certificate" in some cases).
- The Mental Health Act 2025 has received Royal Assent and will bring staged reforms — including replacing the nearest relative with a "nominated person" chosen by the patient, and strengthening patient choice.
What to Do If You or Someone You Know Has Been Sectioned in the UK
If you've been sectioned, the IMHA and the tribunal are the two most important things you can use.
- Ask for an IMHA — Independent Mental Health Advocates know the system, attend meetings with you, help you prepare for the tribunal, and put your wishes on the record. The service is free.
- Appeal to the Mental Health Tribunal. For Section 2, within the first 14 days. For Section 3, within the first 6 months. The tribunal is independent of the hospital and can discharge you.
- Your nearest relative can apply for your discharge — though the responsible clinician can sometimes block it with a barring certificate.
- If you're not detained, the right to refuse treatment is the same as for any other patient — unless the Mental Capacity Act applies.

What should you NOT do?
- Don't assume sectioning strips every right. The right to appeal, the right to an IMHA, the right to dignified treatment, and the right to refuse some treatments survive detention.
- Don't walk out of a voluntary admission without telling staff. If they have concerns, they may apply for a holding power under section 5 — better to discuss the discharge openly.
- Don't refuse to engage with the tribunal. It is your strongest tool for challenging detention, and absent patients still have hearings — but they happen better when you take part.
How Wales differs from UK national law
Quick answer
- Mental Health (Wales) Measure 2010 — additional procedural rights for Welsh patients on top of the MHA 1983.
- The MHA 1983 still applies as the primary detention statute; the Welsh Measure overlays it, it does not replace it.
- Welsh-language Code of Practice + a right to an Independent Mental Health Advocate (IMHA) under section 130A MHA 1983, extended in Wales to voluntary patients.
Wales shares the Mental Health Act 1983 with England, but has additional protections:
- The Mental Health (Wales) Measure 2010 gives additional rights beyond the MHA 1983.
- You have a right to a care and treatment plan from your secondary mental health services.
- You have a right to self-refer back to secondary mental health services within 3 years of discharge — without needing a GP referral.
- You have a right to an independent mental health advocate even if you are a voluntary patient (in England, IMHAs are only available to detained patients).
