The OPG is an agency with responsibilities that extend across England and Wales (separate arrangements exist for Scotland and for Northern Ireland).
It supports the Public Guardian in the registration of Enduring Powers of Attorney (EPA) and Lasting Powers of Attorney (LPA), and the supervision of deputies appointed by the Court of Protection.
It also helps attorneys and deputies to carry out their duties, and protects people who lack the mental capacity to make decisions for themselves.
It works closely with other organisations to ensure that any allegations of abuse are fully investigated and acted on.
The OPG also has responsibility for mental capacity policy, and provides guidance to public, legal and health professionals.
