Nassau County Surrogate Court Departments

Nassau County Surrogate’s Court deals through its various departments with the following matters:

Probate – this department handles estate proceedings involving a will. That’s why some people call it “Nassau County Probate Court.” Most probate proceedings are uncontested – the person who brings in the will (the proponent) submits the will, has their long island estate lawyer fill out the appropriate paperwork and files the original will in the Nassau County Surrogate’s Court, together with a petition, original death certificate, funeral bill and accompanying affidavits and notices. The court will set a date for the hearing on the probate of the will, and if no one appears then the court will grant the probate. If someone does appear, then the estate is contested and the examinations of the attesting witnesses and the attorney-draftsman of the will are scheduled and the cases go on a contested track. In Nassau County, Petitions to Compel Production of a Will are handled by the Probate Department.

Estate Administration – this department handles estates where the person who died did not have a will. The person who is the closest relative of the deceased is appointed as the administrator of their estate. If the decedent is survived by a spouse, the spouse is usually appointed as the administrator. If no spouse, then children. And so on.

Guardianship – this department handles Guardianships. There are two kinds of guardianships – those involving a mentally disabled (special needs) minor (those guardianships are known as 17-a), and guardianships of older adults who have become mentally incompetent due to some sort of illness (this is known as Mental Health Law Article 81 guardianships)

Adoptions – Nassau County Surrogate’s Court also handles adoptions, whether of regular adoptions, step-parent and family adoptions and adoptions from foreign countries, involving both infants and older children.
