Prenuptial agreements have a reputation problem. Many people associate them with distrust, wealthy celebrities, or expectations of failure. In reality, a prenup is a financial planning tool — one that protects both spouses, reduces uncertainty, and can prevent a contentious and expensive divorce process if the marriage ends. Under New York law, couples have broad authority to define their financial rights and obligations through a prenuptial agreement governed by Domestic Relations Law § 236(B)(3).
This post explains the concrete benefits of getting a prenuptial agreement in New York, who should consider one, what a prenup can and cannot cover, and how to approach the process in a way that strengthens rather than strains the relationship.
1. Protect Premarital Assets and Separate Property
New York is an equitable distribution state. Under DRL § 236(B), when a marriage ends, the court divides marital property — property acquired during the marriage — between the spouses based on a list of statutory factors. Property acquired before the marriage is generally considered separate property and is not subject to division.
The problem is that the line between separate and marital property blurs during a marriage. A premarital savings account that receives deposits from marital earnings becomes commingled. A premarital investment portfolio that appreciates during the marriage may be partly marital to the extent the appreciation resulted from either spouse's active efforts. A home purchased before marriage but maintained with marital funds develops a marital interest. Without a prenup, these questions are litigated during divorce — at substantial cost — and the outcomes are unpredictable.
A prenup allows the couple to clearly designate which assets remain separate property, regardless of what happens during the marriage. This clarity eliminates the need for forensic tracing of asset origins during a divorce, which is one of the most expensive components of contested matrimonial litigation.
2. Protect a Business or Professional Practice
For entrepreneurs, business owners, and professionals with ownership interests, a prenuptial agreement can be the most important document they sign. Without a prenup, a business started before the marriage — or even during the marriage — is subject to equitable distribution. The non-owner spouse may be entitled to a share of the business's value, including any appreciation that occurred during the marriage due to either spouse's efforts.
In practice, this means that in a contested divorce, the business must be valued — often through competing expert appraisals that can cost $10,000 to $50,000+ each — and the non-owner spouse may be entitled to a cash buyout, a percentage of future earnings, or in extreme cases, the court may order a forced sale.
A prenup addresses these risks directly: it can designate the business as separate property, establish a valuation methodology (avoiding the "battle of the experts" in divorce), define the non-owner spouse's interest (if any), and prevent the court from ordering a forced sale. For business owners, this single benefit often justifies the entire cost of the prenup many times over.
3. Define Spousal Maintenance (Alimony) Terms
Without a prenup, spousal maintenance in New York is calculated under a statutory formula set forth in DRL § 236(B)(6). The formula considers both spouses' incomes and produces a "guideline" amount and duration. Courts can deviate from the guideline based on numerous statutory factors, making the outcome difficult to predict in advance.
A prenup allows the couple to agree on maintenance terms in advance — whether that means waiving maintenance entirely, setting a specific formula, establishing a cap, or tying maintenance to the length of the marriage. This removes one of the most contentious and unpredictable elements of divorce negotiations.
One important development: the 2025 decision in JM v. GV, 225 NYS3d 859, substantially raised the bar for enforceable maintenance waivers. Under this decision, a maintenance waiver must include the actual incomes of both parties at execution, the statutory maintenance calculation using those figures, and express acknowledgment that the waiving spouse understands the formula and intentionally relinquishes it. Prenups drafted without this level of specificity face significantly greater enforceability risk. An experienced matrimonial attorney will draft the maintenance provisions to comply with this standard.
4. Reduce the Cost of Divorce
A contested divorce in New York commonly costs $15,000 to $50,000 or more per spouse. Complex cases involving business valuations, forensic accountants, custody evaluations, and trial can exceed $100,000. Much of this cost is driven by disputes over financial issues that a prenup could have resolved in advance: What is separate property? How should the business be valued? Is maintenance owed, and if so, how much?
A couple with a comprehensive prenuptial agreement that addresses these issues has already resolved the financial terms of their divorce. If the marriage ends, the divorce can proceed as uncontested — a process that typically costs $2,500 to $8,000 total and finalizes in three to six months. Without a prenup, the same couple might spend a year or more in contested litigation at many times the cost.
The prenup itself is a fraction of these costs. A straightforward agreement typically runs $2,500 to $5,000 for the drafting attorney, plus $1,000 to $2,500 for the other spouse's independent review counsel. Even at the higher end, the total is a fraction of what a single contested divorce motion costs.
5. Protect Inheritance and Family Wealth
Inheritances received during a marriage are generally considered separate property under New York law — but only if they are kept separate. An inheritance deposited into a joint bank account, used to purchase jointly titled property, or otherwise commingled with marital assets loses its separate character. During divorce, the burden of tracing the inheritance back to its separate-property origin falls on the spouse claiming it, and if the tracing fails, the inheritance may be divided.
A prenup can designate all inheritances — whether received before or during the marriage — as separate property, regardless of how they are held or invested. This protects not only the inheriting spouse but also the family members who intended the inheritance to remain within the family. For families with significant generational wealth, a prenup is often a condition of inheritance or trust distribution.
6. Address Real Estate Ownership
Real estate is frequently the largest asset a couple owns, and its treatment in divorce is often the most contentious issue. A premarital home that becomes the marital residence develops a marital interest. A marital home purchased with a down payment from one spouse's separate funds creates tracing disputes. Investment properties purchased during the marriage are marital assets subject to division.
A prenup can address all of these scenarios: designate a premarital home as separate property, establish buyout terms if the marital home must be transferred, allocate investment property, and define how mortgage obligations and equity will be divided. For couples purchasing or owning real estate in New York City — where property values create substantial financial stakes — these provisions are particularly valuable.

7. Protect Against Debt
A prenup can protect each spouse from the other's premarital debts — student loans, credit card balances, business debts, or personal obligations. Without a prenup, debts incurred during the marriage are generally marital obligations subject to allocation in divorce. A prenup can establish that each spouse is responsible for their own premarital debts and define how debts incurred during the marriage will be allocated.
This protection is particularly important when one spouse enters the marriage with significant debt (such as medical school or law school loans) or when one spouse has a business with substantial liabilities. The non-debtor spouse benefits from knowing that the other's debts will not become their responsibility.
8. Coordinate with Estate Planning
Prenuptial agreements and estate plans work together. Under New York law, a surviving spouse has certain rights that cannot be overridden by a will alone — including the right of election under EPTL § 5-1.1-A, which entitles the surviving spouse to a minimum share of the deceased spouse's estate regardless of what the will provides.
A prenup can modify or waive these spousal election rights, allowing each spouse to direct their estate according to their wishes — particularly important for individuals with children from prior marriages, family trusts, or charitable commitments. Without a prenup, estate plans that attempt to favor children from a prior relationship over the current spouse may be partially overridden by the surviving spouse's right of election.
9. Establish Financial Transparency
One of the underappreciated benefits of the prenuptial agreement process is the financial transparency it requires. To draft an enforceable prenup, both parties must provide full and fair financial disclosure — income, assets, debts, business interests, and expected inheritances. New York courts have set aside prenups where meaningful financial disclosure was absent, as in McKenna v. McKenna (2d Dept 2014).
This mandatory transparency means that both spouses enter the marriage with a complete picture of the other's financial situation. Many couples discover that the prenup process prompts financial conversations they had not previously had — about savings goals, spending habits, debt management, and long-term financial planning. These conversations strengthen the marriage, regardless of whether the prenup is ever needed.
10. Provide Certainty and Peace of Mind
Perhaps the most fundamental benefit is certainty. Without a prenup, the financial consequences of divorce are determined by a judge applying broad statutory factors and considerable discretion. Neither spouse can predict with confidence what a court will order regarding property division, maintenance, or asset treatment. This uncertainty creates anxiety during the marriage (“what would happen if...”) and fuels litigation during divorce (“we should fight for more because the outcome is unpredictable”).
A prenup replaces this uncertainty with agreed-upon terms. Both spouses know what the financial outcome of divorce would look like. This knowledge can actually reduce anxiety about the marriage's future — the worst-case scenario is defined and manageable, rather than unknown and frightening.
Who Should Consider a Prenuptial Agreement?
While any couple can benefit from a prenup, certain situations make one particularly valuable:
- Business owners and entrepreneurs who need to protect a business from equitable distribution claims
- Professionals with significant premarital assets — retirement accounts, investment portfolios, real estate
- Individuals expecting significant inheritances or with existing family trusts
- Individuals with children from prior marriages who want to ensure their estate plan is not overridden by spousal election rights
- Couples where one spouse has significant premarital debt — student loans, business debts, or tax obligations
- Couples with substantial income disparity who want to define maintenance terms in advance
- Second marriages where both spouses have established financial lives and want to preserve them
- Couples purchasing property together before or shortly after marriage, who want to define their respective interests
What a Prenup Cannot Do
A prenup is powerful but not unlimited. Under New York law, a prenuptial agreement cannot:
- Waive or predetermine child support. Child support is calculated under the Child Support Standards Act (CSSA) based on parental income at the time of divorce. Any provision waiving child support is unenforceable — children cannot have their rights contracted away by their parents
- Predetermine child custody or parenting time. Custody is determined based on the child's best interests at the time of divorce, not by agreement years before the child's birth
- Include provisions that are unconscionable at the time of enforcement. An agreement that leaves one spouse destitute while the other retains millions may be set aside, even if it was voluntarily signed
- Render either spouse a public charge. Under General Obligations Law § 5-311, a maintenance waiver that would require one spouse to seek public assistance is unenforceable
How to Approach the Prenup Conversation
Many couples avoid prenups not because they don't see the benefits, but because they don't know how to bring up the topic. A few practical suggestions:
Frame it as planning, not distrust. A prenup is in the same category as life insurance, a will, and a business partnership agreement — planning for a possibility, not predicting an outcome. Couples who frame the conversation around mutual protection and financial clarity typically navigate it more comfortably than those who approach it defensively.
Start early. Raising the topic months before the wedding — ideally before engagement — removes the time pressure that can make the process feel coercive. Prenups negotiated under time pressure face both relationship strain and legal enforceability risk.
Both parties should have independent counsel. This is not just a legal best practice — it's a relationship best practice. When each spouse has their own attorney, neither spouse is in the position of dictating terms to the other. The negotiation happens between the attorneys, and both spouses can feel confident that their interests are represented.
Prenuptial Agreements in the Iranian-American Community
For couples in the Iranian-American community, prenuptial agreements interact with the mahr (mehrieh) provision in the Iranian marriage contract (aghd-nameh). The mahr is enforceable in New York as a contractual obligation, and a well-drafted prenup should address how the mahr relates to equitable distribution, spousal maintenance, and overall financial settlement. Failure to coordinate the prenup with the mahr can create conflicting obligations that complicate any future divorce proceedings.
