What to Do When a Client Won't Pay: Legal Options for Unpaid Invoices

When a client won't pay, the escalation ladder runs: a structured dunning sequence ending in a final demand letter (attorney letterhead measurably improves response); small claims court for amounts within your state's limit — commonly $5,000 to $25,000 [LEGAL REVIEW] — where you can appear without counsel; civil litigation for larger amounts, especially where your contract awards attorney's fees to the prevailing party; collections agencies or selling the debt, trading a large percentage for zero effort; and, in construction and certain industries, liens against the property improved — a remedy with strict, short deadlines that must be preserved early. The right rung depends on the amount, your documentation, the client's ability to pay, and whether the relationship is worth anything.

## Triage before tactics
Nonpayment has three species: can't pay (cash-flow distress — payment plans recover more than lawsuits ever will), won't pay (strategic slow-paying, common from large companies toward small vendors — escalation works), and disputes dressed as nonpayment ("the work was deficient") — which is not a collection matter but a brewing contract fight requiring a different posture and careful written communication.

## What decides these cases: your paper
A signed agreement (or even an email chain confirming scope and price), delivery documentation, invoices matching the agreement, and a record of the client's non-objection at delivery. The most common self-inflicted wound is continuing to perform for a non-paying client — most contracts and common sense support suspending work after notice; sunk work rarely gets paid at a higher rate than stopped work.

## The judgment problem
Winning is step one; a judgment is a hunting license, not a check. Collection tools — bank levies, wage garnishment where applicable, liens on property, debtor examinations — take time and work best against defendants with assets. This is why the ability-to-pay assessment belongs at the start of the analysis: a bulletproof case against an empty shell is worth what the shell holds. Prevention completes the loop: deposits, progress billing, personal guarantees from small-company principals, and fee-shifting clauses convert future disputes from essays into arithmetic.
