How to Respond to a Lawsuit in Idaho: Answer a Summons (2026)
Reviewed by DocDraft Legal Team. Idaho. Last updated 2026-06-02
In Idaho, a defendant served with a civil summons and complaint has 21 calendar days to file a written answer under Idaho Rule of Civil Procedure 12(a)(1)(A). The same 21-day window applies in small claims, where Idaho Code § 1-2303 requires the defendant to sign and file a written answer or judgment is entered under Rule 55, and to a response to a divorce or dissolution petition. Eviction is the exception. An unlawful detainer case has no fixed written-answer window. Under Idaho Code § 6-310(2) the court schedules a trial within 12 days of filing and the defendant must appear and respond at that trial, served at least 5 days beforehand. If you miss your deadline, the plaintiff can ask the court to enter your default and the court can enter a default judgment under Rule 55(a), which you can later move to set aside within a reasonable time and no more than 6 months under Rule 60(b).
How long do I have to respond to a lawsuit in Idaho?
It depends on the case type. For a general civil complaint, Idaho Rule of Civil Procedure 12(a)(1)(A) gives you 21 calendar days after the summons is served to file a written answer. Small claims and divorce responses share the same 21-day window. Eviction is different. The court sets a trial within 12 days of filing and you appear and respond there under Idaho Code § 6-310(2), rather than filing an answer by a fixed date.
How do I respond to a civil summons in Idaho?
You respond by filing a written answer with the clerk of the District Court named in the summons, then serving a copy on the plaintiff or the plaintiff's attorney by mail, hand delivery, or electronic service under Idaho Rule of Civil Procedure 5(b). Attorneys must e-file, while self-represented parties may e-file or file in person or by mail. The answer admits or denies each numbered allegation and states your defenses.
What happens if I don't answer a summons in Idaho?
If you do not respond by your deadline, the plaintiff can ask the court to enter your default. Under Idaho Rule of Civil Procedure 55(a)(1), when a defendant fails to plead or otherwise defend, the court must order entry of default, which opens the door to a default judgment for what the complaint requests. You can later move to set the default aside under Rule 60(b).
How do I answer a summons without an attorney in Idaho?
Self-represented defendants can file an answer themselves. Idaho has no statewide general-denial form, so you type your answer with a standard caption on 8.5 by 11 inch paper that meets Idaho Rule of Civil Procedure 10(a), or use a Court Assistance Office form. File it with the clerk, serve the plaintiff, and pay the $100 filing fee or request a fee waiver on form CAO FW 1-9.
Idaho response framework at a glance
Idaho's response rules turn first on which track your case is in. A general civil complaint is governed by Idaho Rule of Civil Procedure 12(a)(1)(A), which directs the defendant to serve a written answer within 21 calendar days after being served with the summons and complaint. Small claims uses the same clock, and it is a real deadline, not an appearance-only track. Idaho Code § 1-2303 requires the small claims defendant to sign and file a written answer within 21 days, or judgment is entered as requested in the claim under Rule 55. A response to a divorce or dissolution petition is also due within 21 days. Eviction is the outlier. Under Idaho Code § 6-310(2) an unlawful detainer has no fixed written-answer window. The court schedules a trial within 12 days of filing, the defendant is served at least 5 days before that trial, and the defense is presented in person at the trial. Answers are filed with the clerk of the District Court named in the summons, served on the plaintiff under Rule 5(b), and formatted with a standard caption on 8.5 by 11 inch paper under Rule 10(a) or on a Court Assistance Office form. The Idaho Court Assistance Office self-help website at courtselfhelp.idaho.gov is the official source for the civil answer forms, the $100 filing fee, and the fee-waiver request (CAO FW 1-9).

Relevant Laws
Idaho Rule of Civil Procedure 12(a)(1)(A) (21-Day Answer to a Civil Complaint)
Requires a defendant to serve an answer within 21 days after being served with the summons and complaint. This is the standard general civil answer deadline in Idaho, and the same 21-day window applies to small claims and divorce responses.
Idaho Code § 1-2303 (Small Claims Written Answer Required)
Requires the small claims defendant to sign and file a written answer within 21 days from the date of service, or judgment is entered as requested in the claim under Rule 55. Idaho small claims is not an appearance-only track. A written answer is mandatory.
Idaho Code § 6-310(2) (Eviction Trial Setting)
Provides that the court schedules an unlawful detainer trial within 12 days of the filing of the complaint and that the defendant is served at least 5 days before trial. There is no fixed written-answer window. The defendant appears and responds at the trial.
Idaho Rule of Civil Procedure 55 (Default and Default Judgment)
Provides that when a party against whom affirmative relief is sought fails to plead or otherwise defend, and that failure is shown by affidavit or otherwise, the court must order entry of the party's default, opening the door to a default judgment.
Idaho Rule of Civil Procedure 60(b) (Setting Aside a Default)
Allows a court to relieve a party from a default or default judgment taken through mistake, inadvertence, surprise, or excusable neglect, on a motion made within a reasonable time and no more than 6 months after the judgment.
Idaho Code § 5-216 (Five-Year Limitations Period for Written Contracts)
Sets the statute of limitations for an action on a written contract at five years, a common threshold defense in debt-collection lawsuits where the underlying account or agreement is in writing.
Idaho Rule of Civil Procedure 13 (Counterclaims)
Requires a defendant to plead a counterclaim arising out of the same transaction or occurrence as a compulsory counterclaim in the answer, or lose the right to assert it later, while unrelated claims may be brought as permissive counterclaims.
Regional Variances
Answer deadline by case track in Idaho
General civil complaint (Idaho R. Civ. P. 12(a)(1)(A))
21 calendar days after the summons and complaint are served on the defendant to serve a written answer. This is the default civil deadline and the one most defendants are working against.
Small claims (Idaho Code § 1-2303)
21 calendar days after service to sign and file a written answer with the clerk. Idaho small claims requires a written answer, unlike some states where the defendant only appears. If no answer is filed in 21 days, judgment is entered as requested in the claim under Rule 55.
Unlawful detainer / eviction (Idaho Code § 6-310(2))
No fixed written-answer window. The court schedules a trial within 12 days of the filing, the defendant is served at least 5 days before trial, and the defense is presented in person at that trial. This is the fastest track, so eviction defendants must focus on the trial date.
Divorce / dissolution response (Idaho R. Civ. P. 12(a)(1)(A))
21 calendar days after service of the petition and summons to file a written response and serve a copy on the petitioner. Missing it can let the dissolution proceed by default.

Frequently Asked Questions
Often yes, if you act quickly. You file a Motion to Set Aside Default under Idaho Rule of Civil Procedure 60(b). The court can relieve you from a default or default judgment taken through mistake, inadvertence, surprise, or excusable neglect under Rule 60(b)(1). The motion must be made within a reasonable time, and in no case more than 6 months after the judgment, so the outer limit is strict.
Sometimes. Parties often agree in writing to extend the answer deadline, and you can ask the court for more time. Filing certain motions that challenge the complaint can also change the timeline. Get any extension in writing, because the 21-day clock keeps running until the plaintiff agrees, the court grants more time, or you file your answer. Do not assume an informal conversation stopped the deadline.
You can ask the court to waive your fee. Idaho's answer filing fee is $100, and you request a waiver on form CAO FW 1-9, the Motion and Affidavit for Fee Waiver. Eligibility is based on your inability to afford court fees given your income and expenses. If the court grants the waiver, you can file your answer without paying the fee.
Yes. Improper service of process is a recognized defense. A defendant can raise insufficient service of process under Idaho Rule of Civil Procedure 12 to challenge whether the court has personal jurisdiction because service did not follow the rules. If service was defective, the time to answer may not have started to run. Raise a service problem promptly rather than ignoring the case, because ignoring it still risks a default.
Respond the same way as any civil complaint. File a timely answer that admits or denies each allegation and raises your defenses. In debt cases, check the five-year statute of limitations for written contracts under Idaho Code § 5-216 and whether the collector validated the debt under the federal Fair Debt Collection Practices Act, 15 U.S.C. § 1692g. Do not ignore the summons, because silence leads to a default judgment for the full amount claimed.
Common affirmative defenses include the statute of limitations, accord and satisfaction, duress, estoppel, and fraud. To assert your own claim against the plaintiff, you file a counterclaim. Under Idaho Rule of Civil Procedure 13(a), a counterclaim arising out of the same transaction or occurrence is compulsory and must be pleaded in your answer or it is waived, while unrelated claims are permissive under Rule 13(b).
A respondent served with a divorce or dissolution petition and summons has 21 days to file a written response and serve a copy on the petitioner, the same window as a general civil case. You file your response with the District Court using the Idaho family-law forms. Missing the 21-day window can let the case proceed by default and let the court decide property, support, and custody issues without your input.
Eviction does not work on a written-answer deadline like other cases. Under Idaho Code § 6-310(2), the court schedules a trial within 12 days of the filing, and you are served with the summons, complaint, and notice of trial at least 5 days before that date. You appear at the trial and present your defense in person. Going to that trial date is the most important step, because missing it can cost you the case.
