2. The Step-by-Step Process

Step A: Choose Your People

Step B: Complete the Forms

The most efficient way to do this is via the Official Online Service, which validates your data as you go to prevent errors.

Step C: Sign the Document

The order of signing is legally critical. If you sign in the wrong order, the OPG will reject the application.

  1. The Donor (You) signs first (witnessed by someone else).

  2. The Certificate Provider signs second.

  3. The Attorney(s) sign third (witnessed by someone else).

Step D: Register the LPA

The document is not legally valid until it is registered with the OPG.


3. Financial Assistance (Fee Reductions)

If you are on a low income or certain benefits, you may not have to pay the full £92 fee.
