NJ Court Rule 4:80-6 Notice of Probate of Will
Within 60 days after the date of the probate of a will, the Attorney for the Estate or the personal representative shall cause to be mailed to all beneficiaries under the will and to all persons designated by R. 4:80-1(a)(3), at their last known addresses, a notice in writing that the will has been probated, the place and date of probate, the name and address of the personal representative and a statement that a copy of the will shall be furnished upon request (many executors and administrators hire an attorney to handle the required notices).
Proof of mailing shall be filed with the Surrogate within 10 days thereof. If the names or addresses of any of those persons are not known, or cannot by reasonable inquiry be determined, then a notice of probate of the will shall be published in a newspaper of general circulation in the county naming or identifying those persons as having a possible interest in the probate estate.
If by the terms of the Will property is devoted to a present or future charitable use or purpose, like notice and a copy of the will shall be mailed to the Attorney General.
It is important to serve and file the notice of probate because it starts the clock ticking on limiting challenges to the Will by unhappy family members. If they wait too long, they will be time barred.
