You are entitled to apply to the Supreme Court for a commission for you work as executor. But if you are also named as a beneficiary in the will the amount you receive will be presumed to be payment for your efforts and you will not be successful with a commission claim. If your efforts have not been very great, the Court may refuse to give you any commission. It is not common to apply for commission.
If you do not want to be an executor (prior to dealing with assets of the estate) you can renounce the executorship by signing a form called a 'renunciation'. We can then file it with the Probate Registry of the Supreme Court.
