Hearing Tool 46: Service, filing, and the periods tied to district receipt

THE RULE

Filing a due process complaint requires service on the other party and forwarding a copy to the State educational agency (34 C.F.R. § 300.508(a); 20 U.S.C. § 1415(b)(7)(A)). For a parent filing in New York, send the original to the school district and a copy to NYSED, and retain a copy and proof of transmission. Send them at the same time.

District receipt of a parent's due process complaint starts two periods, not three periods running together. Within 15 days after receiving notice of the complaint, the district must convene a resolution meeting (34 C.F.R. § 300.510(a)(1)). If the complaint is not resolved to the parent's satisfaction within 30 days after district receipt, the due process hearing may occur (34 C.F.R. § 300.510(b)(1)). The separate 45-day decision period begins after the 30-day resolution period expires or after an earlier adjustment event listed in section 300.510(c); it does not begin on the filing or receipt date (34 C.F.R. §§ 300.510(b)(2), (c), 300.515(a)).

There are adjustments built into the timeline, but only specific events start the 45-day period early. Agreeing to mediate may excuse the resolution meeting, but it does not by itself start the 45-day period. Under 34 C.F.R. § 300.510(c), that period starts the day after one of three events: both parties agree in writing to waive the resolution meeting; after mediation or a resolution meeting starts but before the 30-day period ends, both parties agree in writing that no agreement is possible; or both parties agree in writing to continue mediation at the end of the 30-day period and a party later withdraws from mediation. Separately, nonparticipation can affect the periods under section 300.510(b)(3) to (5), and a hearing officer may grant a specific extension at a party's request under section 300.515(c). District receipt starts the 15-day and 30-day periods; the 45-day decision period starts after expiration of the 30-day period or after an earlier section 300.510(c) event.

As checked on the official pages July 25, 2026, a parent sends the original complaint to the school district and a copy to NYSED, Office of Special Education, Room 309 EB, 89 Washington Avenue, Albany, New York 12234, Attention: Due Process Unit. NYCPS lists email filing at IHOQuest@schools.nyc.gov with speced@nysed.gov included, and also lists mail and fax alternatives. Filing channels are time-sensitive. Recheck the live NYSED and NYCPS pages immediately before service.

Accepted-open caveat, July 25, 2026: Proof of receipt, the identity of the proper district recipient, and unusual service circumstances are case-specific. Preserve transmission and receipt evidence and obtain individualized advice if service is disputed.

WHY IT MATTERS

Manual I's Tool 92 mentions the resolution session and the 45-day decision in passing, as features of the landscape. It does not put them in order or tie them to a single starting event, and that is exactly the mistake that costs parents their footing in the first month.

The most common error is calendaring from the wrong date. A parent finishes the complaint on the 3rd, mails it on the 7th, the district receives it on the 10th, and the parent counts the resolution meeting from the 3rd. The 15-day meeting and 30-day resolution period run from district receipt. The separate 45-day decision period begins after the resolution period or an earlier section 300.510(c) event.

The second error is serving the district and forgetting the State copy. Forwarding the complaint to the State educational agency is required by 34 C.F.R. § 300.508(a), even though district receipt is the event that drives the resolution process.

The third error is a stale address. Filing offices move, and a complaint served on last year's address may not be received when you think it was, which moves every downstream clock without your knowing. This is why the address is a recheck-before-use fact and not a printed constant (NY-15).
