Use the help center early
Court-based help centers assist with locating the right forms, explaining what a paper means, and describing what happens next. Go before your first deadline, not after you have missed one. Bring every paper you have received, in order, and take notes on what you are told to file and by when.
Build a case file
Keep a chronological binder: the contract, the communications, the payments, the notices, and every court paper with its filing date. Prepare a one-page timeline. When you appear, you should be able to answer 'what happened and when' in under two minutes and point to the document that proves each step.
Know what you must prove
Every claim has elements, and you must prove each one. A breach of contract claim needs an agreement, your performance, their breach, and damages you can quantify. Emotional frustration is not damages. Estimates, invoices and receipts are. Identify the weakest element and put your preparation there.
When to get a lawyer
Get counsel when the amount at stake exceeds what a few thousand dollars of legal help would cost, when the other side is represented and the case involves real procedure, when your home or business license is at risk, or when a judgment has already been entered and you need it undone. A consultation is often enough to reorient a case.
