Being sectioned means that you are kept in hospital under the Mental Health Act 1983. You can be sectioned if your own health or safety are at risk, or to protect other people. If you are sectioned, you can be kept in hospital, stopped from leaving the ward and given treatment for your mental health problems, possibly without your consent.
If you have been sectioned and you want to challenge the decision, there are several ways of getting discharged. This can be done in several ways, firstly by asking your hospital managers to consider discharging you, asking your nearest relatives to discharge you by giving the appropriate notice to the hospital managers or by applying to the Mental Health Tribunal.
