Small claims court is intended to be a simple, speedy, and informal procedure. Attorneys are allowed to handle small claims cases but more often parties represent themselves. In New Hampshire, small claims cases are filed in the District Division of the Circuit Court. The Division's website has extensive information about small claims including definitions, checklists, forms, and electronic filing (efiling).
Nolo's Everybody's Guide to Small Claims Court is intended for non-lawyers and is very helpful but it isn't specifically about New Hampshire law so be sure to check the District Division's website as well.
