Identify the claim and the correct party
Write a short explanation of what happened, why you believe money is owed, and how you calculated the amount. Confirm the identity of the person or business involved. A trade name, an employee, and the legal entity responsible for a contract may not be interchangeable.
Do not choose a court solely because it is closest to you. The California Courts venue guide illustrates the need to check where a claim may be filed. Other states use their own rules and limits, and this guide does not provide a nationwide filing amount.
Check prerequisites and dates
Look up the official instructions for the actual court and claim type. California’s small claims demand guidance gives one example of a step before filing. The limitations guide also shows why time limits require specific review rather than a guessed anniversary date.
Record the source and unresolved questions. If a government entity, out-of-state party, unusual contract, or approaching deadline is involved, obtain qualified help promptly.
Match the amount to the evidence
Create an itemized loss sheet and connect each item to a document. An invented $900 invoice dispute might involve the agreed price, proof of work, and payment history. A total in a spreadsheet alone does not establish the agreement or prove performance.
Consider what the other side may dispute and which records address that point. Do not add penalties, interest, or attorney fees merely because a template includes them; check whether there is a lawful basis.
Think beyond filing
Ask about filing fees, service, hearing preparation, accessibility needs, and how a judgment would be collected if you prevail. Winning and receiving payment are separate stages.
Use court self-help resources or a qualified adviser when a rule is unclear. A checklist helps organize a decision; it does not determine whether your claim will succeed. Keep the actual forms and official instructions together, and verify that the required steps were completed rather than assuming an online submission alone finished the process.
