Relation Back After Party Substitution
Farah Fox filed a complaint against Fidelity Trust alleging breach of contract. After the Rule 4(m) period had nearly expired, she realized the proper defendant was Falcon Dynamics and filed an amended complaint substituting that entity. Falcon Dynamics had received the original complaint within the service window and understood the suit targeted it despite the naming error.
Waiver of Personal Jurisdiction Defense
Felipe Figueroa sued Flagship Logistics and received a motion to dismiss for lack of personal jurisdiction. Flagship Logistics filed an answer that omitted the defense entirely. When Flagship Logistics later sought to raise the objection, the court treated it as waived because the company had not included the defense in its initial responsive pleading.

Frequently Asked
4
What timing rule controls amendment as of right under Rule 15(a)(1)?+
A party may amend once as a matter of course within twenty-one days after serving the original pleading or within twenty-one days after service of a responsive pleading or qualifying Rule 12 motion, whichever is earlier.
Does filing an amended complaint as of right reset the defendant's response deadline?+
The defendant must respond within the time remaining to answer the original pleading or within fourteen days after service of the amended pleading, whichever is later.
Can a plaintiff file multiple amendments as of right within the twenty-one-day window?+
No. The rule permits only one amendment as of right. A second filing after the first amendment requires consent or leave of court even if still inside the original time period.
Does a Rule 12(b)(6) motion open a new twenty-one-day window for amendment as of right?+
Yes. When a defendant files a qualifying Rule 12 motion instead of an answer, the plaintiff may amend once as of right within twenty-one days after service of that motion.
