Before you begin — know the assets and liabilities
The most common Mercer County probate mistake is qualifying before the family understands the inheritance-tax exposure. New Jersey taxes transfers by the beneficiary's relationship class, not the size of the estate, and a financial institution may release no more than 50% of a bank balance until a waiver clears (N.J.A.C. 18:26-11.16). Executors who arrive prepared only for the Surrogate fee schedule are often unprepared for the waiver workflow that follows, which holds up the release of accounts and the transfer of real estate.
Before your appointment, identify every bank account, brokerage and retirement account, life insurance policy, business interest, and parcel of Mercer County real estate, along with every debt, and identify each beneficiary by name and inheritance-tax class. The Surrogate's information sheet asks for the approximate value of the estate, so this work is required anyway. Sunset's asset-discovery work, searching more than 2,300 financial institutions, exists for this step.
Which court handles jurisdiction
The Mercer County Surrogate's Court in Trenton serves the entire county, including Trenton (the county seat and New Jersey's capital), Hamilton, Ewing, Lawrence, Princeton, Hopewell, Pennington, Robbinsville, East Windsor, West Windsor, and Hightstown. Every uncontested Mercer probate and intestate administration is handled by the one Surrogate's office at 175 South Broad Street, 4th Floor, Room 420, or at one of the county's satellite offices. Venue lies in the county where the decedent was domiciled at death (R. 4:80-1(c)); if the decedent lived outside New Jersey but owned Mercer County real estate, the estate proceeds here by ancillary administration.
Contested matters do not stay with the Surrogate. A caveat filed at the Surrogate's office, a will contest, a demand for a formal accounting, or removal of a fiduciary routes the matter to the Superior Court of New Jersey, Chancery Division, Probate Part, in the Mercer vicinage, seated in Trenton (vicinage main line (609) 571-4200). The Surrogate also serves as Deputy Clerk of the Superior Court, Chancery Division, Probate Part, and is the procedural gateway to Chancery for those filings.
The jurisdiction process
- Wait the statutory 10 days: no will may be admitted to probate until the 11th day after death (N.J.S.A. 3B:3-22). You may prepare papers and the executor may qualify sooner, but the will is not admitted before then.
- Complete the Surrogate's information sheet for your path (probate of a will, administration when there is no will, or administration C.T.A.), and gather what the office requires: the original will, a certified copy of the death certificate, the executor's government-issued photo ID, the names and addresses of all next of kin and will beneficiaries, and the approximate value of the estate.
- Bring your papers to the Trenton office, or schedule a visit to one of the county's eight satellite offices through (609) 989-6336. For a satellite appointment, return the completed information sheet with copies of the will and death certificate to the office at least 48 hours ahead. If the executor or administrator cannot travel, ask about the Surrogate's homebound service. There is no e-filing for Surrogate probate.
- For a will that is not self-proving, arrange witness proofs before the will can be admitted. The Surrogate takes the proof when you qualify.
- Take the oath and qualify. If you are serving as administrator of an intestate estate, post the required surety bond first (N.J.S.A. 3B:15-1); appointment is not granted until the bond is in place, unless the will waives bond or a statutory exception applies.
- Pay the fees (N.J.S.A. 22A:2-30: $100 to probate a will of two pages or less, or $125 base for administration) and order short certificates at $5 each. The Surrogate retains the original will and gives the executor a certified copy.
- Mail the Notice of Probate to all beneficiaries and heirs within 60 days of probate and file the Proof of Mailing with the Surrogate within 10 days of mailing (R. 4:80-6). If a charity is a beneficiary, mail like notice and a copy of the will to the New Jersey Attorney General.
- Administer and close the estate: creditors have 9 months from the date of death to present claims (N.J.S.A. 3B:22-4); obtain inheritance-tax waivers (L-8, L-9, or O-1) to release frozen accounts and real estate, recording an L-9 or O-1 with the Mercer County Clerk before conveying local real estate; and collect a Refunding Bond and Release from each beneficiary and file it with the Surrogate before closing (N.J.S.A. 3B:23-24).
Forms and documents
Probate forms in Mercer County
New Jersey has no statewide probate form set. Each county Surrogate publishes its own applications, and Mercer hosts its information sheets and forms on the Surrogate's pages at mercercounty.org. There is no separate county cover sheet beyond the information sheet for your path. Qualifying at the Mercer Surrogate requires the original will, a certified death certificate, the executor's photo ID, the names and addresses of the next of kin and beneficiaries, the approximate value of the estate, the fee, and the oath taken when you qualify; short certificates are issued at qualification. The principal Mercer documents:
| Form or category | What it does |
|---|---|
| Information Sheet for Probate | Completed before probating a will; captures the decedent, the executor, the witnesses, the next of kin, the number of short certificates requested, and whether the executor will appear in Trenton or at a satellite office. The same sheet covers administration C.T.A. when no named executor can serve. |
| Information Sheet for Administration | Opens intestate administration when there is no will; the next of kin applies to administer the estate and posts a surety bond. |
| Information Sheet for Affidavit of Surviving Spouse, Domestic Partner or Civil Union Partner, or Next of Kin | Opens the affidavit-in-lieu path for an intestate small estate; the statewide thresholds are on the New Jersey state page. |
| Notice of Probate and Proof of Mailing | R. 4:80-6 requirement: mail notice within 60 days of probate and file the Proof of Mailing within 10 days of mailing. |
| Refunding Bond and Release | Signed by each beneficiary on distribution and filed with the Surrogate before the estate closes (N.J.S.A. 3B:23-24). |
| Renunciation | Notarized form used when a person entitled to serve declines or defers to another of equal or nearer kinship. |
| Caveat / Withdraw Caveat | A caveat blocks probate at the Surrogate and routes the matter to Chancery; withdrawing it releases the matter back. |
Local nuance
Mercer County-specific considerations
Satellite offices reach families across the county. Besides the Trenton office, the Mercer Surrogate runs eight satellite offices around the county where residents can execute probate procedures without traveling to Trenton. Call (609) 989-6336 to find the nearest location and schedule a time.
Homebound service for those who cannot travel. The Surrogate offers homebound Surrogate services for Mercer County residents who are ill or homebound, bringing the probate paperwork to the person's home. Ask about eligibility when you schedule.
Satellite appointments need paperwork 48 hours ahead. For a satellite-office appointment, return the completed information sheet together with copies of the will and the death certificate to the office at least 48 hours before your appointment, so the papers are ready when you arrive.
Banks may release up to half before a waiver clears. A New Jersey financial institution may release up to 50% of a bank account or CD to the survivor or estate representative without the Director's consent (N.J.A.C. 18:26-11.16). The rest waits for a waiver: an L-8 self-executing waiver goes straight to the institution for Class A beneficiaries, while an O-1 waiver from the Division of Taxation is needed when L-8 does not apply. This is the most common practical bottleneck in Mercer estates.
Mercer real estate needs a recorded tax waiver. Before Mercer County real estate can be conveyed, a Class A L-9 waiver (or an O-1 for other classes) must be recorded with the Mercer County Clerk. The Surrogate does not issue tax waivers; they come from the New Jersey Division of Taxation.

Scenarios
| Situation | Likely path in Mercer County | Where Sunset helps |
|---|---|---|
| Surviving spouse, co-owned home | A Trenton, Hamilton, or Princeton home held by the couple as tenants by the entirety (the New Jersey default for married couples) passes to the survivor automatically, with no probate. Bank and brokerage accounts in the decedent's sole name still need a Class A L-8 waiver to release the frozen 50% balance, and the survivor can qualify at a satellite office rather than travel to Trenton. | Asset discovery to confirm what was held jointly versus solely. Packet generation for the L-8 and L-9 waivers. Guidance on clearing title and recording with the Mercer County Clerk. |
| Out-of-state adult child, small estate | If the parent died intestate and the estate is small enough for New Jersey's affidavit-in-lieu path (statewide thresholds apply; see the New Jersey state page), the child, with the other heirs' written consent, files the next-of-kin affidavit at the Mercer Surrogate and then holds administrator powers without full administration. If the parent left a will, even a small estate goes through full probate at the Surrogate; out-of-state executors should call (609) 989-6336 to confirm which steps can be handled by mail or at a satellite office before planning a trip. | Asset discovery to confirm intestacy and that the estate fits the cap. Packet generation for the affidavit in lieu. Coordination with a local Mercer attorney when a trip cannot be avoided. |
| Parent settling a predeceased child's estate, home must be sold | Full intestate administration at the Mercer Surrogate, $125 base fee. The parent qualifies as administrator, posts a surety bond (there is no surviving spouse to take the whole estate), and orders short certificates. A parent inheriting from a child is a Class A beneficiary and owes no New Jersey inheritance tax, but the Mercer home still needs a tax waiver before the deed transfers: an L-9 when no return is required, recorded with the Mercer County Clerk, or a Division-issued O-1 when L-9 does not apply. | Asset discovery for the child's accounts and property. Packet generation for the administration application, bond, and supporting affidavits. Waiver tracking before the home sale. |

When to hire an attorney
A Mercer County attorney is advisable when a caveat is filed and the matter moves to Chancery, where counsel is effectively required; when Class C or Class D beneficiaries owe inheritance tax and a return with valuations and elections is needed; when the estate is insolvent or close to it; when Mercer real estate must be sold and a complicated O-1 waiver is involved; when a will is ambiguous or an accounting is demanded; or when ancillary administration is required for a non-resident decedent who owned Mercer property. For uncontested, Class A-only probate, the affidavit-in-lieu paths, and straightforward administrations, most Mercer families complete the Surrogate intake without an attorney, and the satellite offices and homebound service make that practical. Sunset can connect families to a vetted Mercer County probate attorney when the situation requires counsel.
How Sunset helps
Find the accounts and assets. During estate settlement, Sunset searches more than 2,300 financial institutions and Mercer County public records to surface bank accounts, retirement plans, brokerage holdings, life insurance, Mercer real estate, business interests, and unclaimed property, and flags beneficiary classes early to anticipate inheritance-tax exposure.
Generate the probate packet. Sunset assembles the Mercer Surrogate intake packet: the information sheet for probate or administration with its supporting affidavits, the Notice of Probate and Proof of Mailing, Refunding Bond and Release templates, and the L-8, L-9, and O-1 waiver forms families need after qualifying.
Find a local probate attorney. When the situation calls for counsel, a caveat, a Chancery matter, a Class C or D inheritance-tax filing, or a Mercer real-estate sale, Sunset connects families to a vetted Mercer County probate attorney.
Sunset is free for families. Revenue comes from bank partners that pay Sunset while estate funds sit in an FDIC-insured estate account ($3M coverage).
