Waivers, Deadlines, and Proof
Rule 4(d) waivers trade 21 days for 60. Rule 4(m) gives 90 days from filing to serve — a second clock people routinely lose sight of.
The waiver option
Rule 4(d) lets a plaintiff ask a defendant to waive formal service. The request goes in writing with a copy of the complaint and a prepaid means of returning the waiver form, and must give the defendant at least 30 days to return it.
The tradeoff
Rule 4(d)(3) provides that a defendant who timely returns a waiver doesn't have to answer until 60 days after the request was sent, instead of the 21 days that otherwise applies. Waiving avoids the cost and effort of formal service, and extends the defendant's response time. Rule 4(d)(2) adds that a U.S.-based defendant who fails without good cause to return a waiver may be required to pay the expenses later incurred in making service.
The second 90-day clock
Rule 4(m) states that if a defendant isn't served within 90 days after the complaint is filed, the court — on motion or on its own after notice — must dismiss the action without prejudice as to that defendant, or order that service be made within a specified time. If the plaintiff shows good cause for the delay, the court must extend the time.
Two different 90-day periods
The first runs from receiving the Notice of Right to Sue to filing. The second runs from filing to completing service. They're consecutive, governed by different authorities, and it's common to track the first carefully and lose sight of the second.
Proving it happened
Rule 4(l)(1) requires proof of service to be made to the court, by the server's affidavit unless a marshal served. Rule 4(l)(3) adds that failure to prove service doesn't affect the validity of service, and the court may permit proof to be amended.

Red flags to watch for
- No proof of service filed after service happened
- The Rule 4(m) window running down with no server engaged
- A waiver request sent without a copy of the complaint or return means
