Contested Divorce in New York: Process, Timeline, and Costs

When you and your spouse cannot agree on how to divide assets, calculate maintenance, or arrange custody, the case becomes contested. In New York, that means your divorce moves through the Supreme Court's full litigation track — preliminary conferences, mandatory financial disclosure, formal discovery, and potentially a trial where a judge decides everything for you. The process takes 12 to 24 months on average and costs $15,000 to $50,000 or more per spouse in attorney fees alone.

Understanding what the contested path actually involves helps you make an informed choice about whether to fight for your position in court or redirect energy toward negotiation or mediation before the meter runs that high.

Why It Must Be Supreme Court

New York is unusual in that the Supreme Court — not Family Court — has exclusive jurisdiction over divorce and equitable distribution. Family Court handles child support, custody, visitation, and orders of protection, but it has zero authority to grant a divorce or divide marital property under the New York Constitution.

This distinction matters because spouses sometimes file custody or support petitions in Family Court while a Supreme Court divorce is already pending. Those petitions get dismissed, wasting filing fees and losing strategic positioning. Once a divorce action is commenced in Supreme Court, all financial and custody issues should be resolved there.

The Contested Divorce Timeline

Phase 1 — Filing and Service (Weeks 1-4)

The plaintiff purchases an Index Number ($210) from the County Clerk and files a Summons with Notice or Summons and Verified Complaint. The filing date legally commences the action and triggers two important consequences: it establishes the asset valuation cutoff date, and it binds the plaintiff to the DRL § 236(B)(2)(b) Automatic Orders, which freeze both parties' ability to sell, transfer, or encumber marital assets.

The defendant must be personally served within 120 days. Service binds the defendant to the same Automatic Orders.

Phase 2 — Financial Disclosure (Months 1-3)

Both parties must exchange sworn Statements of Net Worth within 20 days of a written demand. This multi-page document requires full disclosure of income, expenses, assets, and liabilities — listing monthly expenses (weekly amounts multiplied by 4.3), attaching three years of tax returns, and providing current statements for every financial account.

Under the 2026 rules, the Statement is affirmed under penalty of perjury rather than notarized. Providing false or incomplete information can result in preclusion orders that bar the non-compliant spouse from introducing financial evidence at trial.

Phase 3 — Judicial Intervention and Conferences (Months 2-6)

Either party files a Request for Judicial Intervention ($95) to get a judge assigned. The Preliminary Conference must be scheduled within 45 days. At this conference, the judge sets a discovery schedule, identifies contested issues, and may refer the parties to a court-connected mediator or parent coordinator.

Compliance conferences follow at regular intervals to ensure both sides are meeting discovery deadlines.

Phase 4 — Discovery (Months 3-12)

This is where contested cases consume the most time and money. Discovery under the CPLR includes:

• Document demands — requiring production of bank statements, tax returns, business records, real estate appraisals, and retirement account statements
• Interrogatories — written questions that must be answered under oath
• Depositions — sworn testimony taken in an attorney's office, transcribed by a court reporter ($300 to $800 per session)
• Subpoenas — compelling banks, employers, or other third parties to produce records
• Expert valuations — forensic accountants ($5,000 to $15,000) for business valuations, real estate appraisers ($300 to $1,000), and pension actuaries ($500 to $2,000)

When one spouse suspects hidden assets, discovery can include subpoenas for bank records, credit card statements, business financial records, and even social media and digital evidence.

Phase 5 — Pre-Trial (Months 9-18)

Both parties must file Statements of Proposed Disposition and the mandatory Equitable Distribution Spreadsheet at least 5 court days before the pre-trial conference. These documents lay out each side's position on how every marital asset and debt should be divided.

Many cases settle at or shortly after the pre-trial conference, once both sides see the other's full financial picture and proposed division. Judges actively encourage settlement at this stage.

Phase 6 — Trial (Months 12-24)

If settlement fails, the case goes to trial before a Supreme Court judge (no jury for equitable distribution). Each side presents evidence, calls witnesses (including expert witnesses for business valuations, lifestyle analysis, or forensic accounting), and argues their position on the 13 statutory factors under DRL § 236(B)(5)(d).

Trial can last days to weeks depending on the complexity of the marital estate. The judge issues a written decision that becomes the Judgment of Divorce.

What a Contested Divorce Costs

The largest expense is attorney fees. Manhattan matrimonial attorneys charge $400 to $750 per hour; rates in other boroughs and suburban counties run $250 to $500 per hour. With contested cases requiring 40 to 100+ attorney hours, total legal fees per spouse typically range from $15,000 to $50,000. High-net-worth cases with business valuations, forensic accounting, and extended trials routinely exceed $100,000 per side.

Court fees add $335 to $500 (Index Number, RJI, Note of Issue, certified copies). Expert fees — appraisers, forensic accountants, custody evaluators, pension valuators — add $5,000 to $25,000 depending on the complexity.

When Contested Makes Sense (and When It Doesn't)

Litigation is the right path when one spouse is hiding assets, refuses to negotiate in good faith, or when there is a genuine legal dispute about the classification of a major asset (separate vs. marital property, business goodwill, pension valuation methodology).

It is the wrong path when the disagreement is primarily emotional rather than financial. Two spouses who agree on 80% of the financial picture but cannot stop arguing about the remaining 20% often spend $30,000 in attorney fees fighting over $10,000 in disputed assets. A single session with a private mediator ($300 to $500) or a financial neutral can frequently resolve the sticking point for a fraction of the litigation cost.

Preparing Your Financial Position

Regardless of whether your case stays contested or settles along the way, the financial documentation requirements are identical. The Statement of Net Worth, supporting tax returns, and asset/debt inventory must be complete, accurate, and organized.

The New York Divorce Financial Split & Asset Division Guide walks you through this preparation step by step — organizing your financial documents, calculating spousal maintenance under the statutory formula, and building the equitable distribution spreadsheet the court requires. Arriving prepared can save thousands in attorney hours, whether your case settles at the preliminary conference or goes all the way to trial.
