General POA vs LPA — pick the right instrument
A General POA covers ordinary transactions (banking, property sale) and lapses if the grantor loses capacity. A Lasting Power of Attorney (LPA) continues after loss of capacity and is required for care and medical decisions. LPAs must be registered with the OPG (£82 per instrument, 8–20 week processing). iVC drafts both to OPG standards.
