Do my attorneys need to live in the UK?

No. There's no legal requirement that your attorneys are UK residents or UK citizens. Practically, though, attorneys who live abroad can struggle with things like in-person bank visits, immediate hospital decisions, and signing documents. Most people appoint at least one UK-based attorney for these practical reasons, even if other attorneys live overseas. If your only family is abroad, we can talk through how to make it work — there are workable solutions.
