Simon Law Group handles family law, estate planning, probate, personal injury, civil litigation, business, real estate, bankruptcy, foreclosure, workers' compensation, SSDI, and appellate matters in Mercer County.
Mercer County practice scope
Mercer County matters are not all the same just because they share a county name. The useful local question is usually venue, court process, office access, records, travel, local property or employment patterns, and which Simon Law Group practice group should evaluate the issue first.
This page is the general Mercer County service hub. The county-specific divorce page remains available for Family Part details, but Simon Law Group's local work is broader than divorce. We handle family law, estate planning, probate, personal injury, civil litigation, business litigation, legal malpractice, real estate, bankruptcy, foreclosure defense, workers' compensation, SSDI, appeals, criminal defense, DUI/DWI, expungement matters in this county.

Mercer County intake guide
Who this guide helps
Professional and technical workers, finance employees, executives, advisory-firm principals, researchers, and people with deferred compensation or management interests.
What to sort out
Deferred compensation, management roles, advisory relationships, and entity records may be distributed across employers, plans, firms, and custodians. State-government careers add ethics-disclosure filings and accrued-leave payouts to ordinary compensation questions, and university researchers bring grant budgets, sabbatical terms, and laboratory notebooks of their own.
Court and agency routing
This Mercer County page is a routing aid for intake and does not decide the filing division. The appropriate trial-court division, probate or Surrogate process, state agency, or appellate path depends on the matter, and the Mercer Vicinage directory provides official court locations.
Official court source: NJ Courts Mercer Vicinage.
Three intake decisions
- Record whether the person is an employee, executive, researcher, advisor, business principal, shareholder, beneficiary, or fiduciary and identify any government employer or regulated entity.
- Separate deferred-compensation plans, bonus and equity records, management agreements, advisory files, ownership documents, research contracts, and account statements by issuer.
- Note whether the immediate route may involve Family Part, Civil Part, probate or Surrogate processing, a state agency, an appellate court, or another forum for intake review.

Mercer County questions we are asked
Where are Mercer County Family Part cases heard in Trenton?
Mercer County forms a single-county vicinage of the Superior Court of New Jersey. Two Trenton facilities are published on the NJ Courts vicinage directory at njcourts.gov: the Mercer County Civil Courthouse, 175 South Broad Street, Trenton, NJ 08650-0068 and the Mercer County Criminal Courthouse at 400 South Warren Street. Family Division case management for divorce, custody, and support is administered through the Mercer Vicinage Family Division as listed in the NJ Courts family offices directory. Which county a divorce is filed in is set by court rule, not by where either spouse lives today, so a recent move can change the answer. Confirm venue with a lawyer before filing.
Where does a Mercer County will go for probate?
Probate for a Mercer County estate opens at the Mercer County Surrogate's Office at the Mercer County Civil Court House, 175 South Broad Street, 4th Floor, Room 420, Trenton, NJ 08650-0068, inside the civil courthouse in Trenton. Probate of wills, estate administration (appointment of executors and administrators), and applications for letters of guardianship of a minor are filed with the County Surrogate's Office; an adult guardianship case is filed there and heard in Superior Court. Which county's Surrogate opens the estate is set by where the decedent was domiciled at death, and where domicile is unclear that is a question for counsel.
How does a Mercer County custody case reach mediation?
Under the New Jersey court rules, a contested custody or parenting time issue is screened and, if the issue is genuine and substantial, referred to mediation, and every vicinage runs an Early Settlement Program that referred parties are required to attend for the economic side of a dissolution. The rules provide for mediation of the economic aspects after that panel. Whether any of those steps applies to a particular matter, and when, is set by the court rather than by counsel. Mercer County schedules those steps through its Family Division case management staff in Trenton, and the calendar in an individual case is set by the vicinage rather than by counsel.
Which employment records shape Mercer County family cases?
State government service, university and research work, and management roles are common in Mercer County, and each brings its own paper. Public employment adds ethics-disclosure filings and accrued-leave payouts; research positions add grant budgets and sabbatical terms; management roles add deferred compensation and bonus plans. Sorting those by issuer at intake tells the firm which custodian holds the figure a support or equitable distribution analysis will need.
Can a Mercer County matter proceed without a Trenton trip?
Sometimes. Some Family Part and Civil Part events are conducted remotely and some are held in person, and the judiciary sets that format proceeding by proceeding. The controlling instruction is the notice issued in the Mercer County matter, which states the date, the format, and the building. Counsel can appear at many procedural events, though certain hearings require the party. Ask before assuming an appearance can be waived.
