Executors of Wills carry out your wishes once you have died. They will be responsible for winding up your affairs and the administration of your estate. If a grant of probate is needed, they will be responsible for the application. Anyone can be an executor of a Will so long as they are at least 18 years of age at the time of your death and are of sound mind.
We would always recommend choosing an executor who you trust, which could be a close family member, friend or even a professional, such as a solicitor.
