MATRIMONIAL

Strategic Matrimonial Counsel for Complex Estates

Morgan Legal Group handles the matrimonial cases that require more than family-court reflexes — high-net-worth divorces with closely held business interests, prenuptial agreement drafting and litigation under DRL § 236(B)(3), business valuation disputes, forensic discovery of concealed assets, and the post-divorce enforcement work that protects what was won at settlement or trial.

When Matrimonial Cases Become Complex

Matrimonial practice and general family law overlap, but they are not the same discipline. Family law covers the human and child-welfare side of relationships — custody, visitation, support, family offense. Matrimonial work focuses on the financial and contractual dimensions of marriage formation, dissolution, and modification: prenuptial and postnuptial agreements, equitable distribution of complex marital estates, business valuation disputes, and the high-stakes negotiation of separation agreements that often involve eight-figure marital estates, family businesses, professional licenses, deferred compensation, and family wealth that traces back generations.

Prenuptial agreements are governed by DRL § 236(B)(3) and are enforceable in New York if they meet both substantive and procedural fairness standards. Substantively, the agreement must not be unconscionable when made — a wildly one-sided allocation can be set aside even decades later. Procedurally, the agreement must be in writing, signed by both parties, and acknowledged with the formality of a deed (notarized acknowledgment in the form prescribed by Real Property Law § 309-a). Full financial disclosure at the time of signing, independent counsel for each party, and adequate time before the wedding are not strictly required by statute but are the strongest defenses against later attack. Postnuptial agreements are permitted, but they carry a rebuttable presumption of overreaching that requires heightened proof of fairness.

Business valuation is the single most contested issue in high-asset matrimonial work. Under principles developed in O'Brien v O'Brien and its progeny, the enterprise goodwill of a closely held business is marital property subject to equitable distribution; personal goodwill attributable specifically to the owner-spouse's individual skill and reputation generally is not. Forensic accountants and valuation experts apply standards such as fair market value, the discount for lack of marketability for closely held interests, and normalization of owner compensation. The choice of valuation expert and the date of valuation can swing the resulting distribution by seven or eight figures.

High-asset equitable distribution turns heavily on the tracing of separate property and the defense against commingling claims. Under DRL § 236(B)(1)(d), separate property includes assets owned before the marriage, inheritances received during the marriage by one spouse alone, gifts received by one spouse alone (other than from the other spouse), and the appreciation in separate property that is not attributable to the active efforts of either spouse during the marriage. The party claiming separate property bears the burden of proof — without contemporaneous records, separate property can drift into the marital pot through commingling, deposit into joint accounts, or active management by the non-titled spouse.

Full-Scope Representation

Every matrimonial is different. Below are the services we routinely deliver — bundled or à la carte, depending on what your case needs.

Prenuptial Agreements

We draft, negotiate, and execute prenuptial agreements under DRL § 236(B)(3) that protect premarital wealth, family businesses, professional practices, and anticipated inheritances. The agreement is built around the parties' actual situation — full financial disclosure attached as schedules, independent counsel for each party, deed-grade acknowledgment, and adequate time before the wedding. We include sunset clauses, sliding-scale distribution mechanics, and forum-selection provisions where appropriate.

  • DRL § 236(B)(3) compliance and acknowledgment
  • Full financial disclosure as exhibit schedules
  • Independent counsel for each party
  • Sunset clauses and sliding-scale distribution
  • Forum-selection and choice-of-law provisions

Post-Nuptial Agreements

Postnuptial agreements are permitted in New York but carry a rebuttable presumption of overreaching that requires heightened evidence of fairness. We use them to resolve specific issues that have arisen during a marriage — an inheritance one spouse has received, a business interest one spouse has acquired, a settlement after marital reconciliation — while building the contemporaneous record needed to defend the agreement against later attack.

  • Rebuttable presumption of overreaching
  • Heightened review for fairness
  • Use in reconciliation after separation
  • Allocation of newly received inheritances
  • Business-interest carve-outs during marriage

High-Asset Divorce

Eight-figure and larger marital estates require a different toolkit than a typical divorce. We coordinate forensic accountants, valuation experts, tax counsel, and (where appropriate) private investigators. We litigate concealment claims, defend separate property tracings, negotiate complex tax-efficient settlement structures, and prepare the QDROs and deeds needed to implement the resulting allocation. Discretion at every stage is built into the engagement.

  • Forensic accountant and valuation expert coordination
  • Tax-efficient settlement structuring
  • Family business buy-out negotiations
  • Concealment and tracing litigation
  • Discretion and confidentiality protocols

Business Valuation Disputes

In closely held business cases, the valuation question often dominates the distribution. We engage qualified valuation experts (CPA / ABV credentials), litigate the choice of valuation date, contest the discount for lack of marketability, normalize the owner-spouse's compensation, and isolate enterprise goodwill (marital) from personal goodwill (separate). The marginal hourly cost of the right valuation expert is repaid many times over in the resulting distribution.

  • CPA / ABV expert engagement
  • Enterprise vs. personal goodwill analysis
  • Discount for lack of marketability litigation
  • Owner compensation normalization
  • Valuation date and updating analyses

Hidden Asset Discovery

Where one spouse controls the family finances and the other has reason to suspect that assets have been concealed or diverted, forensic financial discovery is the work that levels the playing field. We subpoena bank records, brokerage statements, business records, and tax returns; conduct lifestyle audits to identify spending that exceeds reported income; and engage forensic accountants to trace funds through shell entities and family member accounts.

  • Bank, brokerage, and tax-return subpoenas
  • Lifestyle audits and reverse-engineering
  • Tracing through shell entities and family accounts
  • Forensic accountant engagement
  • Sanctions motions for non-disclosure

Post-Divorce Modifications & Enforcement

After judgment, life changes trigger modification and enforcement issues. We file modification petitions on a substantial-change-in-circumstances showing, defend modification petitions brought by the other party, enforce maintenance and support arrears through income execution and contempt proceedings, and litigate the enforcement of property settlement provisions that did not implement cleanly at the time of judgment.

  • Modification on substantial change in circumstances
  • Enforcement via income execution and contempt
  • Property settlement enforcement actions
  • QDRO reformation and correction
  • Cohabitation termination of maintenance

Our Matrimonial Process

A defined path from pre-engagement planning through post-judgment enforcement.

  1. I

    Pre-Engagement Asset Audit

    For prenup work, we begin with a complete inventory of premarital assets, anticipated inheritances, business interests, professional practice equity, and deferred compensation. The schedules attached to the prenup are built from this inventory, and they later serve as the contemporaneous record that defends the agreement against attack.

  2. II

    Strategic Discovery

    For divorce work, we issue document demands, depose the other party, and subpoena third-party records. Where concealment is suspected, we engage forensic accountants and conduct lifestyle audits. The early discovery posture often determines the strength of the settlement position later.

  3. III

    Valuation & Forensic Engagement

    Closely held business interests, professional practices, and concentrated equity positions are valued by qualified independent experts. We litigate the choice of expert, the valuation date, the discount for lack of marketability, and the allocation of enterprise versus personal goodwill. The valuation case is built methodically over months.

  4. IV

    Negotiation With Full Disclosure

    Settlement negotiations in high-asset matrimonial cases require both sides to operate from a shared financial record. We exchange full disclosure (statement of net worth, supporting documents, valuation reports), build a settlement matrix, and negotiate from a position of trial-readiness. The vast majority of cases settle once both sides see what trial would actually produce.

  5. V

    Settlement or Trial

    A negotiated settlement embodied in a separation agreement is converted to a judgment of divorce on the no-fault ground. Where settlement cannot be reached — typically because of a fundamental valuation dispute or a custody impasse — we prepare and try the case, with the financial sophistication and child-focused advocacy required.

  6. VI

    Post-Judgment Enforcement

    After judgment, we monitor implementation — that retirement plans actually divide under the QDRO, that real estate buy-outs close on schedule, that maintenance payments arrive on time, and that any agreed structured payments perform as drafted. Where implementation breaks down, we file enforcement motions promptly.

Ask Us Directly
Are prenuptial agreements enforceable in New York?

Yes, provided they meet both procedural and substantive standards under DRL § 236(B)(3). Procedurally, the agreement must be in writing, signed by both parties, and acknowledged with the formality of a deed (Real Property Law § 309-a). Substantively, it must not be unconscionable at the time of execution. Full financial disclosure attached as schedules, independent counsel for each party, and adequate time before the wedding are not strictly required by statute but are the strongest defenses against later attack.

Can I draft my own prenup?

Technically yes, but the failure rate is high. DIY prenups regularly omit the deed-grade acknowledgment required by DRL § 236(B)(3), include unconscionable terms that a court will not enforce, fail to attach the financial disclosure schedules needed to defend the agreement against later attack, or are signed too close to the wedding to survive a duress challenge. The marginal cost of competent counsel is repaid many times over if the agreement is ever tested.

How is a business valued in a New York divorce?

Closely held businesses are valued by qualified independent experts (typically CPAs with ABV credentials) using accepted methodologies — income approach (discounted cash flow), market approach (comparable transactions), or asset approach. The discount for lack of marketability is litigated case by case. The owner-spouse's compensation is often normalized to a market rate to isolate the business's actual earning power. Choice of expert and choice of valuation date can swing the resulting distribution dramatically.

What is the O'Brien rule?

O'Brien v O'Brien is the foundational New York case on the treatment of professional credentials and business goodwill in equitable distribution. The doctrine that survives in current practice is that the enterprise goodwill of a closely held business (the goodwill that would transfer to a buyer) is marital property subject to distribution, while the personal goodwill attributable specifically to the owner-spouse's individual reputation and skill is not. The line between the two is the central question in many business-valuation disputes.

Is a professional practice divisible in New York?

The practice itself, as a going concern with enterprise value, is divisible to the extent of its enterprise goodwill. The cash flow generated by the practice is reachable through maintenance and child support obligations. The personal professional credentials (the license itself) are no longer divisible as a standalone marital asset under post-2016 law. The combined effect for most professionals is that the business's enterprise value is part of equitable distribution, but the practitioner's continued earning capacity is captured through support obligations rather than asset division.

How do I prove hidden assets?

Through forensic financial discovery — subpoenas of bank, brokerage, and tax records; depositions under oath; lifestyle audits that compare reported income to actual spending; and tracing analysis through shell entities and family member accounts. Where the record supports it, we file sanctions motions for non-disclosure. The early and aggressive discovery posture is often the single best predictor of recovering concealed assets.

Can spousal maintenance be modified after divorce?

Yes, on a showing of substantial change in circumstances since the prior order. Common modification triggers include a significant change in either party's income, the payee's remarriage (which terminates maintenance), the payee's cohabitation in a marriage-like relationship (which may terminate maintenance under the parties' agreement), the payor's involuntary loss of employment, or the payor's retirement at a reasonable age. The presumptive duration in the original order can also be revisited.

Are inheritances divisible in a New York divorce?

Generally no — under DRL § 236(B)(1)(d), an inheritance received by one spouse alone during the marriage is separate property and not subject to equitable distribution. The protection can be lost through commingling: depositing inherited funds into a joint account, using inherited funds to acquire jointly titled property, or actively managing the inheritance jointly during the marriage. The party claiming separate property treatment bears the burden of tracing the asset back to the inheritance.

What is the New York maintenance formula?

DRL § 236(B)(6) sets a statutory formula for both temporary (pendente lite) and post-divorce maintenance. The calculation involves the parties' incomes, whether child support is also being paid, and (for duration) the length of the marriage on an advisory schedule. For 2024, the formula applies to the first $228,000 of the payor's income; above that cap, the court has full discretion to apply the formula, deviate, or decline maintenance entirely based on the statutory factors.

Is marital fault considered in New York equitable distribution?

Generally no. New York courts since Blickstein v Blickstein and its progeny have held that ordinary marital fault — adultery, irreconcilable differences, garden-variety bad behavior — is not a factor in equitable distribution. The narrow exception is for egregious conduct that shocks the conscience of the court, such as severe domestic violence, attempted murder, or financial conduct that intentionally dissipated marital assets. In ordinary divorces, the equitable distribution analysis is financial, not moral.
