An EPA for Property can be effective immediately or become effective once the Donor loses mental capacity. An EPA for Personal Care and Welfare can only become effective once the Donor loses mental capacity. The "activation" process is reference to an assessment that confirms the Donor has lost mental capacity and the EPA is therefore effective. To activate an EPA a health practitioner's certificate is required which must contain the information prescribed in section 5 Protection of Personal and Property Rights (Enduring Powers of Attorney Forms and Prescribed Information) Regulations 2008.
You can find a standard form of certificate by following this link:

Once the certificate is completed, it should be provided to the lawyer holding the relevant EPA documents who will note that they have been activated. Both the EPAs and the certificate should be provided to third parties, such as the bank, when the EPA is being relied upon.
Activation is not required for property where the Donor has selected for the appointment of the Attorney to be effective immediately.
