Full Text of Rule 8
Plain-English Summary
Rule 8 is the general pleading rule, and it is identical to its civil counterpart subsection by subsection. Subsection (d) is deleted.
Claims
A pleading stating a claim for relief — original claim, counterclaim, cross-claim or third-party claim — must contain a short and plain statement of the claim showing that the pleader is entitled to relief, and a demand for judgment for the relief sought. Relief may be demanded in the alternative or in several different types, which in a domestic relations case is ordinary: divorce, support, custody and division of property in one complaint.
Denials
Subsection (b) requires defenses in short and plain terms and an admission or denial of each averment. A pleader without knowledge or information sufficient to form a belief says so, and that has the effect of a denial. Denials must fairly meet the substance of what is denied; a partial denial must specify what is true and material and deny only the rest. Two sentences at the end are Massachusetts specifics: a signature to an instrument set out in a pleading is taken as admitted unless specifically denied, and an allegation that a place is a public way is taken as admitted unless specifically denied.
Affirmative defenses
Subsection (c) lists them: accord and satisfaction, arbitration and award, assumption of risk, discharge in bankruptcy, duress, estoppel, failure of consideration, fraud, illegality, laches, license, payment, release, res judicata, statute of frauds, statute of limitations, waiver, contributory negligence, injury by fellow servant, and any other matter constituting an avoidance or affirmative defense. The closing sentence is a safety valve: where a party has mislabeled a defense as a counterclaim or a counterclaim as a defense, the court on terms, if justice requires, treats the pleading as if it had been properly designated.
Form and construction
Subsection (e) requires each averment to be simple, concise and direct, requires no technical forms, and lets a party plead alternatively or hypothetically, in one count or several, regardless of consistency and whether the grounds are legal or equitable — all subject to Rule 11. Subsection (f) is the instruction to the court: all pleadings shall be so construed as to do substantial justice.
Frequently Asked Questions
What does a Massachusetts domestic relations complaint have to say?
Rule 8(a) requires a short and plain statement of the claim showing that the pleader is entitled to relief, and a demand for judgment for the relief to which the pleader claims to be entitled. Relief may be sought in the alternative or in several different types.
What happens if I do not plead an affirmative defense?
Rule 8(c) requires a party pleading to a preceding pleading to set the listed defenses forth affirmatively. Where a party has mistakenly designated a defense as a counterclaim, or the reverse, the court on terms, if justice so requires, treats the pleading as if there had been a proper designation.
Can I say I do not know whether an allegation is true?
Yes. Rule 8(b) provides that a party without knowledge or information sufficient to form a belief as to the truth of an averment shall so state, and that this has the effect of a denial.
Can I plead inconsistent claims?
Rule 8(e)(2) allows a party to state two or more claims or defenses alternatively or hypothetically, in one count or in separate counts, and to state as many separate claims or defenses as the party has regardless of consistency and whether based on legal or equitable grounds — subject to the obligations of Rule 11.
