Full Text of Rule 4.16
Amendment History
(Amended October 18, 1977, effective January 1, 1978.)
Plain-English Summary
Summonses and proof-of-service paperwork sometimes contain errors — a misspelled name, a wrong date, an incomplete description of how service happened. Rule 4.16 gives the court authority to fix those errors by amendment rather than forcing a case to restart from scratch. The court can allow the change at any time and can attach whatever conditions it thinks are fair.
That authority has a limit. If amending the summons or the proof of service would clearly prejudice the substantial rights of the party against whom the process was issued, the court cannot allow it. The rule protects a defendant from having a defect papered over after it has caused real harm, while still giving courts room to correct honest mistakes.
