Identify the task, relevant property or case, and limits of authority. Include selling, settlement, receiving funds, signing commitments or delegating to someone else only deliberately and to the extent the task requires.
Confirm formalities with the receiving authority and official document provider. The Ministry of Justice offers digital powers of attorney; a document issued abroad may require attestation and a translation accepted by its recipient.
Keep the final instrument and reference number, and request records of the representative's actions. If you intend to end the authority, check cancellation conditions and procedures and formally notify the representative and relevant bodies.
A practical next step
Before signing, review each power to sell, receive money or delegate separately, and remove powers unnecessary for the intended task.
