When a vendor doesn't deliver, a client won't pay, or a partner breaks an agreement, you have legal options short of court. Court is often the slowest, costliest one. Working through the steps below in order can resolve the dispute faster, cheaper, and without burning the relationship.

1. Re-read the contract first

Before doing anything, read the whole contract again. Find the exact terms that were broken, any notice requirements, any clause that forces mediation or arbitration, and what remedies the contract spells out for a breach.

2. Document the breach

Gather every email, invoice, delivery record, and text that shows the other party fell short. Solid documentation is your strongest asset whether the dispute ends in negotiation, mediation, or a lawsuit.

3. Send a formal demand letter

A clear demand letter puts the other party on notice and often settles things without a lawsuit. State what was promised, what went wrong, what you want to make it right, and a reasonable deadline to respond.

4. Try mediation or arbitration before court

Many contracts require alternative dispute resolution (ADR) before you can sue, and federal law makes written arbitration clauses in contracts involving commerce binding and enforceable. Even when yours doesn't, mediation is usually faster, cheaper, and less hostile than litigation, and it often keeps the business relationship intact.

5. Know when a lawsuit fits

When informal steps fail and the amount at stake justifies the cost, a lawsuit may be the path. For amounts under your state's limit (often $5,000 to $15,000), small claims court is low-cost and doesn't require a lawyer.
