Executor for will

The law does not require an executor (also called a personal representative) to be a legal or financial expert, but it does require the highest degree of honesty, impartiality, and diligence. This is called a "fiduciary duty" -- the duty to act with scrupulous good faith and honesty on behalf of someone else.

It is better to appoint an executor, preferably your advocate who is not a witness, in the Will. It gives more credibility to the Will.
