Executing a will

Does anybody know what happens in a case where a will has 2 executors, and one of the executors in no longer of sound mind, and nobody has power of attorney over his affairs? Is it necessary to go the ward of court route, or can the other executor operate alone in executing the will?

depends on the wording - but normally one executor is enough. - and acting executor "reserves" the right of the non-operating executor.

I don't think it's that simple , I always thought that it was the non acting Executor that reserved their right to act which would cause problems in this case .
May be a good idea to consult a Solicitor.
