You can no longer make or amend an Enduring Power of Attorney (EPA) but can revoke or register an existing one. A power of attorney is a document which allows another person (the donor) to make decisions on your behalf in certain circumstances. In contrast with LPAs, EPAs only relate to property and affairs, not personal welfare, decisions.
