How to Serve Divorce Papers in New York

After filing your divorce papers and purchasing an index number, you have exactly 120 days to serve your spouse. Miss that window and the court can dismiss your case — meaning you'd need to refile, reserve, and potentially repurchase an index number.

Service of process is where many pro se divorces go wrong. Not because the concept is complicated, but because New York's rules are unusually specific about who can serve, when, how, and what they must document.

Who Can Serve

Any person who meets two requirements:

1. At least 18 years old
2. Not a party to the divorce

That means you cannot serve the papers yourself. A friend, family member, coworker, or professional process server can do it — as long as they're 18+ and not involved in the case.

Can you avoid hiring a process server? Yes. There's no requirement to use a professional. Any qualifying person can serve the papers, and doing it this way is free. Professional process servers are typically needed only when the defendant is avoiding service or can't be located.

How Service Must Happen

Personal delivery is the standard method. The server must physically hand the papers to the defendant. They need to:

• Identify the defendant (by appearance, photo, or the defendant identifying themselves)
• Hand them the papers
• Note the exact date, time, and location of service
• Record the defendant's physical description (approximate age, height, weight, hair color)
• Record the defendant's perceived race and gender (required by Chapter 473 of the Laws of 2024)

Service cannot happen on a Sunday. New York law absolutely prohibits service of process on Sundays. Service on the defendant's religious observance day is also banned.

Completing the Affirmation of Service (Form UD-3)

After serving the papers, the server must complete Form UD-3 — the Affirmation of Service. This form must include:

• The date, time, and address where service happened
• A physical description of the person served
• The perceived race and gender of the person served
• How the server identified the defendant
• The server's signature, sworn before a notary

A UD-3 missing the physical description, race, or gender will be rejected by the clerk. This is one of the most common rejection triggers for the entire divorce packet.

What If Personal Service Fails

If your spouse is avoiding service or can't be found, you must first make diligent, documented attempts at personal delivery before the court will authorize alternative methods.

Substituted service: Leave the papers with a person of suitable age and discretion at the defendant's residence or business, then mail a copy to their last known address. Both steps must happen within 20 days of each other.

Conspicuous service ("nail and mail"): Affix the papers to the door of the defendant's residence or business, then mail a copy. Again, both steps within 20 days.

Service by publication: If the defendant truly cannot be located, you can petition the court for permission to serve by publishing a notice in a designated newspaper. This is a last resort that adds significant time and cost.

For substituted or conspicuous service, service is not legally complete until the Affidavit of Service is filed with the County Clerk — and then only 10 days after filing. The defendant's response window doesn't start until that date.

The 120-Day Deadline

The clock starts when you file your initial papers and purchase the index number. If you haven't completed service within 120 days, the court may dismiss the action on its own motion. You can apply for an extension before the deadline passes, but you'll need to show good cause for the delay.

Keep a written log of every service attempt — dates, times, locations, what happened. If you need to request an extension or permission for alternative service, this documentation is what the court will evaluate.
