Dissipation of Marital Assets in New York: Suing a Spouse for Wasting Money on Affairs or Gambling

Discovering that your spouse has secretly drained your joint bank accounts to fund an extramarital affair, feed a gambling habit, or sabotage a family business is devastating. While New York is a no-fault divorce state where marital infidelity rarely affects property division on its own, the financial betrayal behind that behavior is treated very differently. Under New York law, draining shared funds for non-marital purposes is officially known as the wasteful dissipation of marital assets.

Generally, New York courts do not punish a spouse simply for making a bad investment during the marriage. However, when one spouse intentionally, recklessly, or secretly squanders money as the marriage is breaking down-or uses joint wealth for purely selfish, non-marital activities-the court can step in. By proving economic fault in the Supreme Court, you can seek a dollar-for-dollar credit or an unequal share of the remaining marital estate to make you financially whole.

Common Scenarios of Wasteful Dissipation in New York

In New York matrimonial litigation, the legal boundary between normal marital spending and actionable dissipation was clarified in Mahoney-Buntzman v. Buntzman, 12 N.Y.3d 415 (NY Court of Appeals 2009). In that landmark decision, the court held that normal living expenses and prior obligations paid during the marriage cannot be clawed back, except when a spouse engages in egregious economic fault or secret, wasteful transfers.

Money Spent on Paramours: Hotels, Gifts, and Travel

While having an affair is not a standalone reason for a judge to penalize a spouse financially, spending marital money on an affair partner (legally referred to as a paramour) is a textbook example of wasteful dissipation. Because money spent on a paramour provides zero benefit to the marriage or family, courts routinely classify these expenditures as economic misconduct.

• Luxury Gifts and Jewelry: Purchases from high-end retailers, designer clothing, watches, or electronics bought for a third party.
• Travel and Accommodations: Airline tickets, resort stays, boutique hotel charges, and dining tabs accrued during secret getaways.
• Living Expenses for a Third Party: Paying rent, car leases, utility bills, or cash transfers via Venmo and Zelle to support a paramour.

Gambling Addictions and Reckless Crypto Losses

When a spouse depletes savings at casinos, sportsbooks, or online betting platforms without the other spouse's knowledge or consent, New York courts frequently treat those losses as wasteful dissipation. In Wilner v. Wilner, 192 A.D.2d 524 (NY App. Div. 1993), the appellate court affirmed that a spouse who unilaterally squanders marital funds through unexplained cash withdrawals and financial misconduct can be held solely responsible for the missing equity.

The same principle increasingly applies to high-risk, unilateral cryptocurrency speculation or day-trading schemes. If both spouses agreed to invest in volatile digital assets hoping for a family windfall, both generally share the loss. However, if one spouse secretly liquidates a marital 401(k) or home equity line of credit to gamble on unverified tokens-or hides funds in cold-storage crypto wallets while claiming the money was lost-the judge may assign 100% of that loss to the reckless spouse.

Intentionally Destroying or Devaluing a Family Business

Since O'Brien v. O'Brien, 66 N.Y.2d 576 (NY Court of Appeals 1985), New York has recognized that business interests and professional practices built during the marriage are marital property subject to equitable distribution. Sometimes, a business-owning spouse attempts to tank company revenues right before filing for divorce to make the enterprise look worthless on paper.

Whether a spouse intentionally turns away loyal clients, delays signing lucrative contracts until after the divorce is filed, puts phantom employees on the payroll, or funnels corporate assets into a cousin's new LLC, New York courts have strong remedies. Under N.Y. Dom. Rel. Law § 236(B)(5)(d)(12) and N.Y. Dom. Rel. Law § 236(B)(5)(d)(13), a judge can value the business as of an earlier date prior to the sabotage, as seen in cases like Wegman v. Wegman, 123 A.D.2d 220 (NY App. Div. 1986), and award the innocent spouse their fair share of what the business was truly worth.

How a New York Judge Adjusts Equitable Distribution

New York is an equitable distribution state, meaning marital property is divided fairly, though not always 50/50. When wasteful dissipation is proven, the judge uses a mathematical clawback mechanism. Rather than ordering your spouse to write you a check from money that no longer exists, the court adds the wasted amount back into the hypothetical marital pot and deducts it directly from the offending spouse's share of remaining assets, such as home equity or retirement accounts.

Step-by-Step Process in New York

Whether you live in Manhattan, Brooklyn, Queens, Nassau County, or Buffalo, all divorce actions and claims for wasteful dissipation must be filed in the Supreme Court of the State of New York (which serves as the state's trial-level court for matrimonial cases, unlike the Family Court, which cannot divide property).

Step 1: Secure Preliminary Financial Records

Before confronting your spouse, gather copies of the last 3 to 5 years of joint and individual tax returns, bank statements, credit card bills, mortgage documents, and brokerage summaries. Look for sudden ATM withdrawals in casino towns, unfamiliar boutique charges, or unexplained wire transfers.

Step 2: File the Divorce Action and Trigger Automatic Orders

To freeze the financial status quo, your attorney initiates the case by filing Form UD-1, New York, Unified Court System, Summons With Notice or Form UD-2, New York, Unified Court System, Verified Complaint at your county courthouse, such as the New York County Supreme Court, Civil Branch, New York at 60 Centre Street, the Kings County Supreme Court, Civil Term, Brooklyn at 360 Adams Street, or the Erie County Supreme Court, Buffalo at 92 Franklin Street. Under N.Y. Dom. Rel. Law § 236(B)(2)(b), filing and serving Form Notice of Automatic Orders, New York, Unified Court System, Automatic Orders Pursuant to DRL 236(B)(2)(b) immediately prohibits both spouses from transferring, encumbering, or dissipating any marital property outside of customary living expenses.

Step 3: Exchange Sworn Statements of Net Worth

Both parties are legally required to complete and exchange Form Statement of Net Worth, New York, Unified Court System, Sworn Statement of Net Worth under penalty of perjury. If your spouse omits hidden crypto wallets, undervalues a business, or lies about transferred cash on this mandatory form, they destroy their credibility with the judge and open the door to severe financial sanctions.

Step 4: Issue Subpoenas and Hire a Forensic Accountant

Using discovery powers under N.Y. C.P.L.R. § 3101 and N.Y. C.P.L.R. § 3120, your divorce lawyer can issue subpoenas duces tecum directly to banks, credit card companies, casinos, cryptocurrency exchanges, and airlines. In complex cases at venues like the Nassau County Supreme Court, Matrimonial Center, Mineola or the Queens County Supreme Court, Civil Term, Jamaica, attorneys frequently retain a Certified Forensic Accountant to conduct a lifestyle analysis and trace every missing dollar.

Step 5: Present the Dissipation Claim at Settlement or Trial

Once the forensic audit compiles an itemized spreadsheet of every dollar spent on affairs, gambling, or business sabotage, your lawyer uses this evidence as leverage during settlement negotiations. If your spouse refuses to offer a fair credit, the evidence is presented at an equitable distribution trial for the judge to adjust the final property division.

How Much Does it Cost in New York?

Pursuing a dissipation claim requires balancing the cost of investigation against the amount of money you expect to recover. Typical costs in New York include:

• Supreme Court Index Number Fee: $210 mandatory state filing fee under N.Y. C.P.L.R. § 8018.
• Request for Judicial Intervention (RJI) & Motion Fees: $95 to assign a judge, plus $45 per motion if you file an emergency Order to Show Cause to freeze accounts.
• Subpoena and Bank Record Fees: Usually $15 to $50 per subpoena, plus bank reproduction fees of $0.25 to $1.00 per page.
• Forensic Accountant Fees: Depending on complexity, retaining a forensic CPA in New York typically costs between $5,000 and $25,000+.
• Matrimonial Attorney Fees: Experienced New York divorce attorneys generally charge hourly rates between $350 and $750+ per hour, with retainers ranging from $5,000 to $15,000.

How Long Does the Process Take?

Tracing dissipated funds adds time to a standard divorce timeline. While an uncontested divorce in New York can conclude in 3 to 6 months, a contested divorce involving financial discovery, third-party bank subpoenas, and forensic business valuations typically takes 12 to 24 months from the filing of the Summons to a final Judgment of Divorce. However, if your spouse is actively draining accounts, your lawyer can file an emergency Order to Show Cause to freeze assets within 24 to 72 hours.
