The person to whom you give the duty of carrying out the instructions given in your will, after your death, is called the executor of the will.
You can appoint any person who is of sound mind and who is above 18 years of age to be your executor. You must choose a person with whom you have full confidence and who is willing and capable of acting as the executor.
When you haven’t appointed an executor in your will, the court has the power to appoint an administrator who will execute your will.
