All the witnesses should sign at the same time and add their addresses.
If an heir at law, say a child, is not mentioned in the will, the law assumes that he was forgotten by the testator and generally gives the share the heir would be entitled to if there were no will.
At the end of the will the testator, in the presence of the witnesses, should write his name in full.
AN EXECUTOR'S DUTIES
An executor is the legal representative of the testator. It is his duty to see that the provisions of the will are carried out.
No man is qualified to act as executor who is not competent to make a will. Executors, unless relieved by the provisions of the will, are required to file bonds, proportioned to the value of the estate, for the faithful performance of their duties.
Should there be no executor named in the will, or if the person so named refuses to act, or if he dies or resigns, the court will appoint a person to act in his place.
The executor appointed by the court is known or called an "administrator with the will annexed."
In some states the court having jurisdiction of wills and estates of deceased is known as "the probate," in others it is called the "Surrogate's Court," and in still others, "The Orphan's."
