If you have made a will and appointed a representative to carry out your last wishes they are called an executor for male and an executrix for female.
If you have not appointed a representative in your will, the person delegated the responsibility will be called an administrator. When appointing an executor, make sure that you trust the person as they will be carrying out your last will and testament.
The executor will make decisions in the best interest of your estate. As there is a lot of paper work and administrative duties connected to this responsibility, the executor may be paid a fee for handling your last request.
You should choose someone who is organized and accustomed to dealing with a lot of paper work such as death certificate, insurance policies and bank accounts. Before selecting someone for this responsibility, make a wise judgement.
