Emergency deadline checklist for New York

The short answer

In New York, the default appellate deadline for an appeal as of right is 30 days after service of (1) a copy of the judgment or order and (2) written notice of its entry. This comes from N.Y. CPLR § 5513(a).

Important: No claim-type-specific sub-rule was found for this checklist. So treat this as the general/default period for appeals as of right unless you have a specific rule for your appeal type.

Gentle note: This is general timing information, not legal advice. Deadline disputes often turn on what was actually served and on the exact service date.

What changes the deadline

Under N.Y. CPLR § 5513(a), the biggest driver is service, not the date you received the decision informally or the date it was “entered” in the court’s docketing system.

Common variables that shift (or clarify) the 30-day deadline:

• When “service” occurred

  • The clock is measured from the date the other party served you (the appellant) with the required materials.

• Whether “written notice of its entry” was included

  • CPLR § 5513(a) requires service of:

    • a copy of the judgment/order, and
    • written notice of its entry.
  • If you were served with a decision but not the written notice of entry, your relevant “service date” for the 30-day period may be different (or the period may not start as you initially assumed).

• What you are appealing

  • The quoted 30-day language applies to an appeal as of right from a judgment or order.

• Service proof and specific dates

  • DocketMath needs a concrete service date. If there are multiple affidavits of service, resubmissions, corrections, or later re-service, the service date(s) reflected in your paperwork can change the calculated deadline.

Quick reality checks

• The deadline may land on a weekend or holiday, depending on how the counting rules operate in your procedural posture—so don’t assume “30 days later” always equals a business day.
• The most common cause of “deadline moved” problems is using the wrong date (for example, relying on “entered” in the docket instead of the service date tied to CPLR § 5513(a)).

Inputs checklist

Before you run DocketMath, gather the inputs that matter for CPLR § 5513(a)—especially the service date.

Collect (as applicable):

• Service date: The date the other party served you (the appellant) with:

  • a copy of the judgment/order, and
  • written notice of entry (not just a copy of the decision).
• Document type: Are you appealing a judgment or an order?
• Appeal status: Confirm this is an appeal as of right (not discretionary).
• Written notice of entry: Have proof that written notice of entry was served along with the judgment/order copy?
• Proof of service: Keep the affidavit/unsworn declaration showing:

  • the date and
  • the method of service.
• Jurisdiction selection: Use New York (US-NY).

If you have multiple service attempts (e.g., re-service, amended/corrected notice of entry, or revised paperwork), note which one your records support as starting the period.

Run it in DocketMath

1. Open DocketMath at /tools/deadline
2. Select:

   • Jurisdiction: New York (US-NY)
   • Calculator mode / rule: use the option consistent with an appeal as of right under N.Y. CPLR § 5513(a).
3. Enter the key date:

   • the service date of the judgment/order copy and the written notice of entry.
4. Check the result:

   • DocketMath should calculate the 30-day deadline under CPLR § 5513(a).

Fast troubleshooting workflow

• Run once using the earliest service date you have.
• If your proof suggests the written notice of entry was served later, run again using that later service date.
• Compare outputs—this helps you see how sensitive the deadline is to the service-date input.

Pitfall to avoid: Don’t assume DocketMath should use a docket “entry date.” Under CPLR § 5513(a), the timing is tied to service upon the appellant, plus the written notice of its entry.
