When Do You Need a Amended Complaint?

The court has granted a motion to dismiss template your original complaint with leave to amend, giving you the opportunity to cure the deficiencies identified by the court. The court's order will specify what defects must be corrected, failure to state a claim, insufficient factual allegations, or missing elements of a cause of action, and you must address each one in the amended complaint or risk dismissal with prejudice.

Discovery has revealed new facts, new claims, or new theories of liability that were not available when the original complaint was filed. For example, depositions may have uncovered additional wrongdoing, document production may have revealed a previously unknown party's involvement, or interrogatory responses template may have disclosed facts supporting an additional cause of action such as fraud or conspiracy.

You need to add or remove defendants from the lawsuit. Adding a defendant requires meeting the requirements for joinder under Rule 20 FRCP (permissive joinder) or Rule 19 (required joinder). Removing a defendant requires voluntary dismissal under Rule 41(a) or stipulation. The amended complaint must replead all allegations against all remaining and new defendants.

Your original complaint contained pleading deficiencies that you identified before the defendant moved to dismiss, incorrect dates, missing factual allegations, improperly pleaded claims, or failure to meet the heightened pleading standard of Rule 9(b) for fraud claims (which requires particularity: who, what, when, where, and how).

📋 Amendment as of Right: Under Rule 15(a)(1) FRCP, a party may amend its pleading once as a matter of course within 21 days after serving it, or within 21 days after service of a responsive pleading or a Rule 12(b), (e), or (f) motion, whichever is earlier. No leave of court or consent of the opposing party is required during this window. After the as-of-right period expires, you must obtain either the opposing party's written consent or leave of court under Rule 15(a)(2), which the court should "freely give when justice so requires."

⚠ Statute of Limitations, Relation Back Doctrine: If the statute of limitations has expired since the original complaint was filed, your amended complaint must satisfy the relation back doctrine under Rule 15(c) FRCP to avoid being time-barred. An amendment relates back to the date of the original complaint if it arises out of the same conduct, transaction, or occurrence. For new defendants, relation back requires that the new defendant received notice of the action within the service period, knew the action would have been brought against them but for a mistake in identity, and the amendment arises from the same transaction. Failure to satisfy Rule 15(c) means the amended claims or parties are subject to a statute of limitations defense.

What Should a Amended Complaint Include?

Amended Caption

The case caption must clearly identify the document as a "First Amended Complaint" (or "Second Amended Complaint," etc.), include the original case number, and list all parties, including any newly added defendants. The caption should match the court's formatting requirements and reference any court order granting leave to amend.

Repleaded Allegations

An amended complaint supersedes the original complaint entirely, it must replead all allegations from the original complaint that you wish to preserve, plus any new allegations. Do not incorporate the original complaint by reference; courts in most jurisdictions require the amended complaint to be a standalone, self-contained document. See Lacey v. Maricopa County, 693 F.3d 896 (9th Cir. 2012).

New Causes of Action

Each new cause of action should be set forth as a separate numbered count, with the factual basis clearly stated and the legal elements identified. For fraud claims, comply with the heightened pleading standard of Rule 9(b) by alleging the who, what, when, where, and how of the fraudulent conduct.

Conformity With Court Order

If the amendment was ordered by the court (e.g., after granting a motion to dismiss with leave to amend), the amended complaint must address every deficiency identified in the court's order. Courts will dismiss with prejudice if the plaintiff fails to cure the identified defects after being given the opportunity to do so.

Certificate of Service

A certificate of service confirming that the amended complaint was served on all parties, including any newly added defendants who must be served with a summons template in accordance with Rule 4. Existing parties are served through the case's electronic filing system or by mail.

Signature Requirements

Check Local Court Rules

Court filings may require wet ink or e-filing system signatures. Check your jurisdiction's e-filing rules before filing.

How to Fill Out a Amended Complaint

1

Review the Court's Order or Identify the Deficiencies

If amending after a motion to dismiss, carefully analyze the court's order to identify every deficiency you must cure. If amending as of right or based on new facts, review the original complaint alongside any new evidence from subpoena sample document responses or discovery to determine what allegations to add, modify, or remove.

2

Draft the Amended Allegations

Replead every allegation from the original complaint that remains relevant, incorporating changes and additions. Number paragraphs consecutively. Add new factual allegations to support any new claims or cure identified deficiencies. Ensure all allegations are consistent, do not contradict factual positions taken in the original complaint unless you have a valid basis for the change.

3

Add New Claims or Parties

Draft each new cause of action as a separate count. For new defendants, include allegations establishing the basis for the court's jurisdiction over them and the factual basis for their liability. Ensure any new claims satisfy the relation back requirements of Rule 15(c) if the statute of limitations is a concern.

4

File and Serve the Amended Complaint

If amending as of right, file the amended complaint with the court and serve all parties. If leave of court is required, first file a motion for leave to amend under Rule 15(a)(2), attaching the proposed amended complaint as an exhibit. New defendants must be served with a summons and copy of the amended complaint under Rule 4.

5

Track the Response Deadline

Existing defendants must respond to the amended complaint within 14 days of service (or the remaining time for responding to the original complaint, whichever is longer) under Rule 15(a)(3). New defendants have the standard 21 days to respond. Calendar all deadlines and monitor for motions to dismiss template the amended complaint.

Amended Complaint Template FAQ

What is the difference between amending a complaint as of right versus with leave of court?
Under Rule 15(a)(1) FRCP, a party may amend its complaint as of right, without needing the court's permission or the opposing party's consent, within 21 days after serving the original complaint, or within 21 days after the defendant serves a responsive pleading or a Rule 12(b), (e), or (f) motion, whichever is earlier. After this window closes, Rule 15(a)(2) requires either the opposing party's written consent or leave of court, which the court "should freely give when justice so requires." Courts consider four factors when deciding whether to grant leave: undue delay, bad faith, repeated failure to cure deficiencies, and undue prejudice to the opposing party. See Foman v. Davis, 371 U.S. 178 (1962). Leave is routinely granted for first amendments but becomes harder to obtain after multiple amendments or when discovery is closed.
What is the relation back doctrine Rule 15?
The relation back doctrine under Rule 15(c) FRCP allows an amended pleading to "relate back" to the filing date of the original complaint for statute of limitations purposes. An amendment relates back if it arises out of the same conduct, transaction, or occurrence set out in the original pleading (Rule 15(c)(1)(B)). For adding new defendants, Rule 15(c)(1)(C) requires three conditions: (1) the amendment arises from the same transaction; (2) the new defendant received notice of the action within the time allowed for service (90 days under Rule 4(m)) such that they will not be prejudiced; and (3) the new defendant knew or should have known that the action would have been brought against them but for a mistake concerning their identity. The Supreme Court in Krupski v. Costa Crociere S.p.A., 560 U.S. 538 (2010), held that the focus is on what the new defendant knew, not on the plaintiff's diligence.
How many times can you amend a complaint?
There is no fixed limit on the number of times a complaint can be amended, but each successive amendment becomes harder to obtain. The first amendment as of right under Rule 15(a)(1) requires no permission. Subsequent amendments require leave of court under Rule 15(a)(2). Courts become increasingly skeptical of multiple amendments, if the plaintiff has already had several opportunities to state a valid claim and has failed each time, courts will deny further leave on the grounds of futility or undue delay. Additionally, courts may impose conditions on amendment, such as limiting the scope of changes or requiring the plaintiff to bear the costs of additional discovery caused by the amendment. After discovery closes, amendments are rarely permitted because they would cause undue prejudice to the defendant.
What is the difference between an amended complaint and a supplemental complaint?
An amended complaint under Rule 15(a) replaces the original complaint and addresses facts and claims that existed at the time of the original filing or that were discovered through litigation. A supplemental complaint under Rule 15(d) adds claims based on events that occurred after the original complaint was filed. For example, if a defendant commits additional acts of breach after the lawsuit was filed, those new acts are raised in a supplemental complaint, not an amended complaint. Supplemental complaints do not replace the original, they add to it. Leave of court is always required for a supplemental complaint under Rule 15(d); there is no as-of-right supplemental pleading. Courts will permit supplemental pleadings when the new claims are related to the original claims and arise out of the same course of conduct.
