Probate Process in Mercer County
When a resident of Mercer County dies, their estate goes through probate at the Surrogate's Office in Trenton. If the person left a will, the executor brings it to the office along with the death certificate. The Surrogate reviews the will and admits it to probate. This creates a set of probate court records that become part of the Mercer County file.
If there is no will, a family member can apply for Letters of Administration. The Surrogate's Office issues these letters after reviewing the application and confirming the applicant's right to serve. The administrator then has the legal power to gather assets, pay debts, and distribute what remains. Each step in this process creates probate court records on file with the Mercer County Surrogate.
Small estates may qualify for a simpler path. Estates with limited personal property can use a small estate affidavit to avoid the full probate process. The staff in Trenton can tell you if an estate qualifies.
