An executor is responsible for looking after your money, property and other assets after your death and carrying out the wishes in your Will. You can appoint relatives, friends or professionals (such as solicitors), or a mixture, up to a maximum of four. A beneficiary of your Will, such as your spouse, can act in this role and may be the only executor, if appropriate. At least one substitute executor should be included. If your estate is to be held in trust for young or vulnerable beneficiaries, it is good practice for there to be at least two executors who can act together.
