Filing limits, service, and collecting judgments.
New Hampshire courts apply both the U.S. Constitution and the New Hampshire Constitution to small claims court claims. When state protections are broader than federal ones, New Hampshire judges follow the state rule. When they are equal or narrower, federal precedent controls under the Supremacy Clause.
Federal cases governing small claims court include controlling U.S. Supreme Court decisions and binding precedent from the federal circuit covering New Hampshire. Civil remedies most often proceed under 42 U.S.C. § 1983, with defenses including qualified immunity.
