DEFENDANT'S ANSWER, COUNTERCLAIM, AND CROSS-CLAIM


2. INTRODUCTION AND GOVERNING RULE

Defendant / Counterclaimant [DEFENDANT FULL LEGAL NAME] ("Counterclaimant"), by and through undersigned counsel, and pursuant to Idaho Rule of Civil Procedure 13, asserts the following Counterclaim(s) against Plaintiff [PLAINTIFF FULL LEGAL NAME] ("Counterclaim-Defendant") and the following Cross-Claim(s) against Co-Defendant [CO-DEFENDANT FULL LEGAL NAME] ("Cross-Claim Defendant").

These claims are asserted as part of, and are filed together with, Counterclaimant's Answer pursuant to Idaho R. Civ. P. 7(a) and 12(a)(1)(A). Counterclaimant incorporates by reference each admission, denial, and affirmative defense set forth in its Answer as though fully restated herein.


3. PARTIES; COMPULSORY VS. PERMISSIVE CLASSIFICATION

3.1. Counterclaimant [DEFENDANT FULL LEGAL NAME] is, and at all relevant times was, a [individual / corporation / LLC] [residing in / organized under the laws of] [County / State].

3.2. Counterclaim-Defendant [PLAINTIFF FULL LEGAL NAME] is the Plaintiff in the above-captioned action and is, and at all relevant times was, a [individual / corporation / LLC] [residing in / organized under the laws of] [County / State].

3.3. Cross-Claim Defendant [CO-DEFENDANT FULL LEGAL NAME] is a co-defendant in the above-captioned action and is, and at all relevant times was, a [individual / corporation / LLC] [residing in / organized under the laws of] [County / State].

3.4. Classification of the Counterclaim(s) under Idaho R. Civ. P. 13. Counterclaimant designates each Counterclaim asserted herein as follows:

☐ Compulsory Counterclaim — Idaho R. Civ. P. 13(a). The claim arises out of the transaction or occurrence that is the subject matter of Plaintiff's claim and does not require adding another party over whom the Court cannot acquire jurisdiction. Under Rule 13(a), a pleading "must state as a counterclaim any claim that — at the time of its service — the pleader has against an opposing party" that meets these criteria. A compulsory counterclaim not pleaded is generally waived.

☐ Permissive Counterclaim — Idaho R. Civ. P. 13(b). The claim is any claim against an opposing party that is not compulsory. A pleading "may state as a counterclaim against an opposing party any claim that is not compulsory."

3.5. Pursuant to Idaho R. Civ. P. 13(c), a counterclaim need not diminish or defeat the recovery sought by the opposing party and may request relief that exceeds in amount or differs in kind from the relief sought by Plaintiff.

3.6. To the extent any Counterclaim or Cross-Claim asserted herein matured or was acquired after service of an earlier pleading, Counterclaimant reserves the right to seek leave to file a supplemental pleading under Idaho R. Civ. P. 13(e). To the extent adjudication of any claim requires joinder of an additional party, Counterclaimant invokes Idaho R. Civ. P. 13(h), and Rules 19 and 20.


4. JURISDICTION AND VENUE

4.1. This Court has subject-matter jurisdiction over these Counterclaim(s) and Cross-Claim(s). The District Court is a court of general jurisdiction over civil actions in Idaho.

4.2. The Court has personal jurisdiction over Counterclaim-Defendant, who submitted to the jurisdiction of this Court by filing the Complaint. The Court has personal jurisdiction over Cross-Claim Defendant, who is a party already before the Court in this action.

4.3. Venue is proper in this County under the applicable Idaho Code § 5-404 branch because [the cause of action arose here / an individual Defendant resided here when the action commenced / a qualifying Idaho corporation has its principal place of business here / OTHER CURRENT STATUTORY BASIS].


5. FACTUAL ALLEGATIONS COMMON TO ALL COUNTS

9.1. Cross-Claimant [DEFENDANT NAME] realleges and incorporates Paragraphs 3.1 through 5.6 as though fully set forth herein.

9.2. Authority. This Cross-Claim is asserted under Idaho R. Civ. P. 13(g), which permits a pleading to "state as a crossclaim any claim by one party against a coparty if the claim arises out of the transaction or occurrence that is the subject matter of the original action or of a counterclaim, or if the claim relates to any property that is the subject matter of the original action."

9.3. This Cross-Claim arises out of the same transaction or occurrence that is the subject matter of Plaintiff's Complaint and/or relates to the property at issue in this action.

CROSS-CLAIM COUNT B — CONTRIBUTION / APPORTIONMENT OF FAULT

In the alternative, to the extent Cross-Claimant and Cross-Claim Defendant are determined to be joint or concurrent tortfeasors or otherwise jointly responsible, Cross-Claimant is entitled to contribution from, and apportionment of fault to, Cross-Claim Defendant in proportion to its respective share of responsibility for Plaintiff's alleged damages.

15. IDAHO PRACTICE NOTES

  • Governing rule. Idaho Rule of Civil Procedure 13 governs counterclaims and crossclaims and closely tracks Fed. R. Civ. P. 13. Rule 13(a) makes a counterclaim compulsory when it arises out of the same transaction or occurrence as the opposing party's claim and does not require adding a party beyond the court's jurisdiction; Rule 13(b) makes all other counterclaims permissive.

  • Responsive-pleading deadline. Under I.R.C.P. 12(a)(1)(A), a defendant must serve an answer within 21 calendar days after being served with the summons and complaint. A counterclaim and cross-claim are pleaded with the answer. A party served with a counterclaim or crossclaim must serve a response within 21 days after service of that pleading (I.R.C.P. 12(a)(1)(B)). Filing a Rule 12(b) motion alters these periods.

  • Waiver of compulsory counterclaims. A claim that qualifies as compulsory under Rule 13(a) but is not asserted is generally barred in any later action. When in doubt, plead the claim and designate it compulsory.

  • Cross-claim scope. Rule 13(g) permits a cross-claim against a coparty only when it arises from the same transaction or occurrence as the original action or a counterclaim, or relates to property at issue. Claims for indemnity and contribution ("all or part of a claim asserted in the action against the crossclaimant") fit squarely within Rule 13(g).

  • Joinder. Idaho R. Civ. P. 13(h) incorporates Rules 19 and 20 for adding parties to a counterclaim or crossclaim. If a needed party is not yet before the court, plan for service of process under I.R.C.P. 4.

  • Court name and structure. The trial court of general jurisdiction in Idaho is the District Court, organized into seven judicial districts. Use the correct judicial district and county in the caption.

  • Attorney fees. Idaho Code § 12-120 provides for fees in certain commercial and contract actions; § 12-121 allows fees to the prevailing party where the case was brought, pursued, or defended frivolously, unreasonably, or without foundation. Plead the fee basis.

  • E-filing. Idaho uses the iCourt File & Serve system; attorneys must e-file. Confirm local district practices and any cover-sheet requirements.

These are the filings that drive a lawsuit through the system: complaints, answers, motions, briefs, discovery requests and responses, and post-judgment papers. Each has its own format requirements under federal and state procedural rules, and each has a deadline that cannot be missed without consequences. Clean, procedurally correct filings move a case forward; sloppy ones invite motions to strike, amended responses, and avoidable delays.
