You can apply for the right to deal with the benefits of someone who cannot manage their own affairs because they’re mentally incapable or severely disabled.
Only 1 appointee can act on behalf of someone who is entitled to benefits (the claimant) from the Department for Work and Pensions (DWP).
An appointee can be:
an individual, for example a friend or relative
an organisation or representative of an organisation, for example a solicitor or local council
