Mercer County estate planning attorneys -- Trenton wills, trusts, and probate.
Wills, trusts, powers of attorney, advance directives, probate, and estate administration for Mercer County families -- probated through the Mercer County Surrogate's Office in Trenton, with attention to the state pensions, university retirement plans, and pharmaceutical equity that estate plans here often have to account for.
Estate planning and probate in Mercer County
More than most places in New Jersey, an estate plan in Mercer County is built around a paycheck's benefits rather than a deed. The county concentrates state-government employment, university employment (Princeton, Rider, The College of New Jersey), and pharmaceutical-industry employment, so state pensions under PERS or TPAF, university TIAA accounts, deferred compensation, and equity grants show up in estate plans here more often than in most New Jersey counties. Those assets do not change the core documents, but they do affect how a plan is structured for beneficiary designations, incapacity planning, administration, and tax exposure.
We help Mercer County clients prepare wills, trusts, powers of attorney, and advance directives, and we assist executors and administrators through probate and estate administration after a death. Our offices are in Somerville, Morristown, and Flemington, and appearances and filings at the Mercer County Surrogate's Office in Trenton are a routine part of our estate practice. We aim to build plans that are practical to administer, not just technically valid on paper.
The Mercer County Surrogate's Office
In New Jersey, probate and routine estate administration run through the County Surrogate -- not the Family Part and not the Law Division. The Mercer County Surrogate's Office is located at the Mercer County Civil Court House, 175 South Broad Street, 4th Floor, Room 420, Trenton, NJ 08650. The Surrogate is an elected constitutional officer who serves as Deputy Clerk of the Superior Court, Chancery Division, Probate Part, and the office handles probate of wills, the appointment of executors and administrators, and the guardianship of minors. Contested matters -- a will challenge, a removal application, or an accounting dispute -- are transferred to a Superior Court judge sitting in the Probate Part.
After a death, a will cannot be admitted to probate until the eleventh day, because R. 4:80-1 source bars probate before the tenth day following death. The named executor brings the original will and a certified death certificate to the Surrogate, who reviews the will for facial validity, confirms proper execution under N.J.S.A. 3B:3-2 source , and accepts a self-proving affidavit under N.J.S.A. 3B:3-4 source where one is attached. When the will is valid and uncontested, the Surrogate issues Letters Testamentary so the executor can act. The Surrogate's Office sits inside the Mercer County Civil Court House on South Broad Street -- the same building that houses the Superior Court's civil Law Division -- but it is a separate office with its own function: you file a will and open an estate at the Surrogate, not at the civil courtroom down the hall, and a contested probate matter is what moves from the Surrogate to a judge.

Wills and guardianship of minor children
A will directs how your probate assets pass and names the executor who will administer the estate. For parents, it is also where you nominate a guardian for minor children. To be valid in New Jersey, a will must generally be signed by the testator and two witnesses under N.J.S.A. 3B:3-2 source ; adding a self-proving affidavit under N.J.S.A. 3B:3-4 source lets the will be admitted without locating the witnesses years later. One caution for Mercer households in particular: a will only governs probate assets, so the pension, TIAA, IRA, and 401(k) or deferred-comp balances that make up much of the wealth here pass by beneficiary designation and are untouched by what the will says. A carefully drafted will that fights a stale beneficiary form will lose to the form. If you die without a will, your probate estate passes under New Jersey's intestacy statute, N.J.S.A. 3B:5-3 source , which may not match your intentions.
Trusts -- revocable, irrevocable, and special-needs planning
A trust is not required for every estate, but it can help where privacy, probate avoidance, incapacity planning, beneficiary control, blended-family goals, multi-state real estate, or a beneficiary with a disability are in play. A revocable living trust keeps assets out of probate and provides a management structure if you become incapacitated; irrevocable trusts are used for asset protection, tax planning, and legacy goals; and a special-needs trust can preserve a disabled beneficiary's eligibility for public benefits. For Mercer households whose wealth is concentrated in retirement plans and deferred compensation rather than real estate, the beneficiary-designation and trust-coordination work is often where the real planning happens. We match the structure to the goal rather than defaulting to any single instrument.
Powers of attorney and advance directives
Incapacity planning is the part of an estate plan that operates while you are alive. A durable financial power of attorney lets a trusted agent manage your finances if you cannot, and an advance directive for health care -- a living will together with a health care proxy -- states your treatment wishes and names who speaks for you. For Mercer clients whose accounts sit with a pension system, a university plan, or a large employer's benefits administrator, the power of attorney has to be drafted with enough reach to actually deal with those custodians -- authorizing retirement-account transactions, benefit elections, and beneficiary questions -- because a bare-bones form that stops at ordinary banking can leave an agent locked out of exactly the accounts that hold the money. Without these documents, your family may have to seek a court-appointed guardianship, which is slower, public, and more expensive.
Probate and estate administration
After a death, the executor or administrator gathers assets, gives statutory notice to beneficiaries and next of kin, pays valid debts and taxes, and distributes what remains. New Jersey allows reasonable executor commissions -- corpus commissions under N.J.S.A. 3B:18-13 source and income commissions under N.J.S.A. 3B:18-14 source . Smaller estates may qualify for an affidavit procedure under N.J.S.A. 3B:10-3 source and N.J.S.A. 3B:10-4 source that skips full administration when the statutory limits are met. We assist Mercer executors and administrators through each step, including estates with pension, retirement-account, or closely held business assets that need valuation or accountings.
New Jersey inheritance tax and the Mercer estate
New Jersey repealed its state estate tax for deaths on or after January 1, 2018, but it still imposes an inheritance tax under N.J.S.A. 54:34-1 source et seq. The inheritance tax turns on who inherits, not on the size of the estate: close family (Class A) is exempt, while more distant beneficiaries such as nieces, nephews, and unmarried partners (Class D) can face meaningful tax. For Mercer families whose estates include tax-deferred retirement accounts, deferred compensation, or a business interest, the interaction of inheritance tax, income tax on inherited retirement assets, and the federal estate and gift tax system matters, and current thresholds should be confirmed with counsel before you rely on them.

Frequently asked questions
▸ Where is a will probated in Mercer County?
A Mercer County will is admitted to probate through the Mercer County Surrogate's Office, located at the Mercer County Civil Court House, 175 South Broad Street, 4th Floor, Room 420, Trenton, NJ 08650. The County Surrogate is an elected constitutional officer who serves as Deputy Clerk of the Superior Court, Chancery Division, Probate Part. Probate can begin only after the tenth day following death under R. 4:80-1source. The Surrogate reviews the will for facial validity -- proper execution and, where available, a self-proving affidavit -- and, if it appears valid and uncontested, issues Letters Testamentary to the named executor. A will contest or other genuine dispute is transferred to a Superior Court judge sitting in the Probate Part.
▸ Is the Surrogate's Office the same as the Family Part?
No. Think of them as two doors within the Mercer Vicinage in Trenton that never lead to the same room. Behind the first is the Mercer County Surrogate's Office, which admits wills to probate, appoints executors and administrators, and oversees guardianship of minors. Behind the second is the Superior Court, Chancery Division, Family Part, which decides divorce, custody, child support, and domestic violence cases. An estate matter filed with the Family Part -- or a custody question brought to the Surrogate -- simply lands in the wrong office, because each operates under its own set of court rules.
▸ What documents make up a basic New Jersey estate plan for a Mercer family?
A New Jersey estate plan starts with a will that directs how your probate assets pass and names an executor and, for parents, a guardian for minor children. Most plans also include a durable financial power of attorney and an advance directive for health care (living will plus health care proxy) so someone can act if you become incapacitated. What is easy to miss -- and what matters a lot in Mercer, where households often hold a PERS or TPAF pension, a university TIAA account, or an employer 401(k) and deferred compensation from the pharmaceutical corridor -- is that those accounts pass by beneficiary designation, outside the will entirely. If the designation is stale or contradicts the will, the form wins. A real Mercer estate plan lines up the will, any trusts, and the beneficiary forms on every retirement and life-insurance account so they say the same thing. Depending on goals -- probate avoidance, privacy, a blended family, special-needs beneficiaries, or asset protection -- a revocable living trust or one or more irrevocable trusts may be added. There is no single correct package; the right structure depends on your assets, your family, and how those retirement accounts are titled.
▸ Does New Jersey tax an inherited pension or retirement account, and how does that hit a Mercer estate?
New Jersey eliminated its state estate tax for decedents dying on or after January 1, 2018. It continues to impose an inheritance tax under N.J.S.A. 54:34-1source et seq., which taxes transfers based on the beneficiary's class rather than the size of the estate. Spouses, civil-union partners, children, grandchildren, and parents (Class A) are exempt; siblings and children-in-law (Class C) receive a limited exemption then graduated rates; and more distant beneficiaries such as nieces, nephews, friends, and unmarried partners (Class D) are taxed without a class exemption. Charities and similar organizations (Class E) are exempt. There is a second layer that catches a lot of Mercer families: a traditional pension distribution, a 401(k) or 403(b), a TIAA account, or a deferred-comp balance is tax-deferred, so the person who inherits it also owes ordinary income tax as the money comes out -- that is income tax on the beneficiary, separate from and on top of any state inheritance tax on the transfer itself. Naming the right beneficiary, and deciding whether a see-through trust should sit between the account and a beneficiary, is where a plan controls that bill. The federal estate and gift tax is a separate system with its own high exemption. Because thresholds and rates change, confirm current figures with counsel before relying on them.
▸ Can a small New Jersey estate skip full probate, and do retirement accounts count?
New Jersey provides a simplified affidavit process for small estates. Under N.J.S.A. 3B:10-3source, when a surviving spouse, civil-union partner, or domestic partner is the sole beneficiary and the total value of the estate's real and personal assets does not exceed the statutory amount, that survivor may claim the assets by affidavit instead of formal administration. N.J.S.A. 3B:10-4source provides a parallel, lower-limit procedure for other heirs when there is no will. What surprises many Mercer families is which assets count toward the limit: a pension, IRA, TIAA balance, or 401(k) with a valid beneficiary designation, and a life-insurance policy paid to a named person, are non-probate transfers that pass directly and do not enter the probate estate at all. So a household with a large TPAF pension and a modest bank account can sometimes still use the affidavit route, while a smaller-sounding estate that owns a Trenton or Hamilton home usually cannot -- the home's value counts toward the cap on the estate's real and personal assets, and even where the numbers work, the affidavit procedure does not itself transfer title to real estate. The current dollar limits should be confirmed before relying on them.
