How to File for Divorce in New York: A Step-by-Step Guide

Before you can file for divorce in New York, you must meet residency requirements. New York Domestic Relations Law requires that at least one spouse must be a resident of New York State for at least two years before filing. If you have only recently moved to the state, you must wait until the two-year mark or file in the state where your spouse resides.

Once you meet the residency requirement, you may file in any county where either you or your spouse resides. For residents of Western New York, that means the Erie County Supreme Court in Buffalo, which handles divorce cases for Williamsville, Amherst, Cheektowaga, and surrounding communities.

New York recognizes both no-fault and fault-based grounds for divorce under the Domestic Relations Law Section 170. The most common ground is no-fault divorce: irretrievable breakdown of the marriage. Under this ground, you must testify that the marriage has broken down irretrievably for at least six months. You do not need your spouse to agree; you simply need to demonstrate this breakdown.

Fault-based grounds include adultery, cruelty, abandonment, and imprisonment. However, most divorces in New York proceed on no-fault grounds because they are faster and less contentious. Your attorney can help you determine the strongest ground for your specific situation.

In Erie County, divorce cases are filed in the Supreme Court, which has exclusive jurisdiction over matrimonial matters. You will not file in Family Court initially, though Family Court may handle issues like custody and support if disputes arise later.

The Erie County Supreme Court is located in downtown Buffalo and has a dedicated matrimonial part (a judicial unit) that handles divorce cases. All papers must be filed with the Erie County Clerk and served according to New York rules.

The first step is to prepare the legal documents required to commence your divorce. These typically include:

• Summons: The document that formally notifies your spouse of the divorce case and their right to respond. The Summons includes the grounds for divorce and basic information about the parties and their residence.
• Complaint: A detailed document that states the grounds for divorce and provides facts supporting that ground. It also lists any claims for spousal support, child support, child custody, or property division.
• Affidavit of Irretrievable Breakdown (if no-fault): Your sworn statement affirming that the marriage has broken down irretrievably for at least six months.
• Matrimonial Summons: New York requires a specific matrimonial summons form that includes required language about your rights and obligations.
• Verification: A sworn statement that attests to the truth of allegations in the complaint.

If you and your spouse have agreed on all issues (child support, custody, property division, and spousal support), you may also prepare a Separation Agreement or Stipulation of Settlement, which will speed up your case significantly.

Once your papers are prepared, you must file them with the Erie County Clerk. The Clerk's office is located at 25 Delaware Avenue, Buffalo, NY. You will file:

• The Summons and Complaint (or Summons with Notice, if simpler)
• The Affidavit of Irretrievable Breakdown (for no-fault divorces)
• The Matrimonial Summons
• A Verification
• The filing fee (currently approximately $300–400, depending on county fees)

The Clerk will assign your case a case index number, which you will use on all future documents. Filing can be done in person, by mail, or increasingly, electronically through the New York State's NYSCEF (New York State Courts Electronic Filing) system. We recommend electronic filing for efficiency and immediate confirmation of filing.

After you file, you must legally serve a copy of the Summons and Complaint on your spouse. New York law requires proper service of process, which must be completed before or with your complaint filing (though filing can proceed with an affidavit of service to follow). Service can be done in several ways:

• Personal service: A process server or sheriff physically delivers the papers to your spouse. This is the most reliable method.
• Certified mail with return receipt: Can be used if your spouse's address is known, though personal service is preferred.
• Nail and mail: Affixing papers to your spouse's door and mailing a copy, available only if personal service cannot be effected.
• Publication: If your spouse's location is unknown, you may serve by publishing a notice in a newspaper, but only after court permission.

You must file an Affidavit of Service proving to the court that your spouse was properly served. This affidavit is critical; without it, your case cannot proceed.

After being served, your spouse has 30 days to respond to your complaint by filing an Answer and, if they wish, a Counterclaim. If they do not respond within 30 days and you have proper proof of service, you may move for a default judgment.

In an uncontested divorce, your spouse's attorney (if they have one) will typically respond by filing a Notice of No Answer (meaning they are not contesting the case). In a contested divorce, they will file an Answer denying certain allegations and may file a Counterclaim asserting their own claims for custody, support, or property division.

Once your spouse responds (or the response period closes), the discovery phase begins. Discovery is the formal exchange of information and documents:

• Interrogatories: Written questions about finances, assets, liabilities, income, and other relevant facts.
• Requests for Production of Documents: Demands for financial statements, tax returns, bank statements, investment account statements, and business records.
• Depositions: Sworn, recorded interviews of witnesses or parties to explore facts under oath.
• Expert appraisals: For significant assets (real estate, businesses, retirement accounts), you may retain appraisers or valuators.

Concurrently, your attorney will engage in settlement negotiations—often called "four-way conferences" where both attorneys and both parties meet to try to resolve disputed issues. Many cases settle during this phase. If your divorce is uncontested from the start, discovery is minimal or skipped entirely.

If you and your spouse reach agreement on all issues, you will execute a Stipulation of Settlement (or Separation Agreement) that details the resolution of property division, spousal support, child support, and custody. This document, signed by both parties and reviewed by a judge, becomes the final judgment.

If you cannot reach agreement, your case will proceed to trial before a judge in Erie County Supreme Court. At trial, you and your spouse will present evidence (testimony, documents, expert reports) on the disputed issues. The judge will then issue a Judgment of Divorce detailing their rulings on property, support, custody, and all other matters.

Once the judge signs the Judgment of Divorce, your marriage is legally dissolved as of that date. The judgment includes:

• The grounds for divorce
• Division of marital property and debt
• Award of spousal support (if applicable)
• Award of child support (if applicable)
• Custody and visitation arrangement for children (if applicable)
• Any other orders (e.g., name change, retirement account division via QDRO, health insurance continuation)

The judgment is filed with the Erie County Clerk and becomes a public record. You receive a certified copy, which you can use to prove your unmarried status for purposes of remarriage, updating your will, or changing your name.
