Typically, the person named as the deceased’s Personal Representative (a more formal term is “Executor” or “Executrix”) goes to an attorney experienced in probate matters, who then prepares a “Petition” for the court and takes it, along with the Will, and files it with the probate court.
The lawyer for the person seeking to have the Will admitted to probate typically must notify all those who would have legally been entitled to receive property from the deceased if the deceased died without a Will, plus all those named in the will, and give them an opportunity to file a formal objection to admitting the will to probate.
A hearing on the probate petition is typically scheduled several weeks to months after the matter is filed. Depending on the state, and sometimes who the named beneficiaries are, how long before the death the Will was signed, whether the Will was prepared by an attorney, who supervised the “execution” of the Will, and/or whether the Will was executed with certain affidavits, it may be necessary to bring in the persons who witnessed the deceased’s signature on the Will.
If no objections are received, and everything seems in order, the court approves the petition, appoints the Personal representative, orders that taxes and creditors be paid, and requires the Personal Representative to file reports with the court to assure all the deceased’s property is accounted for and distributed in accordance with the terms and conditions of the Will.
