The executor is the personal representative of an estate.  The executor is appointed to take charge of your assets, pay off any debts, and distribute assets to your beneficiary/beneficiaries as stipulated in the terms and conditions of your will.  While you may name any person you choose to be the executor of your will, it is a good idea to select someone competent and trustworthy.  Your executor should be named in your will.  The person you select has the right to refuse, so it is recommended that you have a backup executor in place just in case.
