UK Mental Health Act 1983

What is the Mental Health Act 1983? This guide explains the legislation of the Mental Health Act (MHA) 1983 in England and Wales.

MHA 1983: The law informs people with mental health problems what their rights are on:

  • Assessment and treatment in hospital
  • Pathways into hospital (civil or criminal)
  • Treatment within the general community

Those who receive inpatient treatment on psychiatric wards have agreed to go into hospital.

They do so as informal patients and are also known as voluntary patients.

But, around 50% of inpatients are in a hospital without their agreement as formal patients. They will have been detained under the Mental Health Act 1983. You may be more familiar with the term of ‘getting sectioned’.

You lose certain rights if you are a formal patient including the right to leave hospital freely. So, knowing your rights under the Mental Health Act is important for those in this situation.


What the Mental Health Act Covers

There are many different sections to the Mental Health Act. Each section contains information on:

  • Your rights if you get detained in hospital against your wishes.
  • Your family’s rights if you get detained.
  • Your rights if you get detained in hospital and also part of the criminal justice system.
  • Your rights around consent to treatment when you get detained.
  • Your rights when you are leaving hospital (including how to have your section lifted and care planning).
  • Your rights if you get treated in the community (e.g. receiving section 117 aftercare or on a community treatment order (CTO)).
