Filing a claim against a business in small claims court can be straightforward—but your success largely depends on the evidence you provide.
Courts want clear, organized, and verifiable documentation that proves your claim.
Understanding what evidence is needed when suing a business can save you time, prevent delays, and increase your chances of winning.
This guide breaks down the types of evidence typically accepted, practical tips for collecting it, and common mistakes to avoid.
Why Evidence Matters in Small Claims Court
Small claims courts are designed to help individuals resolve disputes efficiently, but they still require proof. Without evidence, even a legitimate claim can be dismissed.
Proper evidence helps to:
- Establish that the business owes you money or failed to meet its obligations
- Demonstrate the amount of your damages clearly
- Show that you followed all necessary steps before filing
- Strengthen your credibility in front of the judge

Step 1: Receipts and Invoices
Receipts and invoices are often the first line of evidence in small claims cases. They provide tangible proof of transactions, payments, or services rendered.
Key points to include:
- Date of purchase or service
- Amount paid
- Method of payment (credit card, check, cash)
- Description of goods or services
If your receipt is missing or incomplete, try to obtain a copy from the business or check your bank/credit card statements. Even online transactions can be verified through digital receipts or confirmation emails.
Step 2: Contracts and Agreements
Written contracts are extremely valuable evidence. They outline the terms of your agreement with the business and can prove breach of contract or unmet obligations.
Include in your evidence:
- Signed contracts, including digital agreements
- Terms and conditions relevant to your claim
- Amendments or email confirmations of agreed changes
Step 3: Emails, Texts, and Written Communication
Courts accept written correspondence that documents your attempts to resolve the issue or proves the business’s commitments.
Examples include:
- Emails confirming orders or services
- Messages showing promises made by the business
- Letters requesting payment or correction of issues
Tip: Organize your messages chronologically and print or save them in PDF format to present clearly.
Step 4: Photographs and Videos
Visual evidence can be powerful, especially for claims involving defective goods, property damage, or poor services.
Best practices:
- Take clear, dated photos or videos of the product, damage, or work performed
- Show close-ups of defects, receipts, or labels
- Include wide shots to provide context

Step 5: Witness Statements
Sometimes, third-party testimony strengthens your claim. Witnesses can support your account of events or verify damages.
Examples of useful witnesses:
- Employees who observed defective service
- Contractors who assessed property damage
- Customers who experienced similar issues with the business
Have witnesses provide written statements, signed and dated, if possible.
Step 6: Delivery Records and Tracking Information
For claims involving shipping or delivery:
- Keep tracking numbers, delivery confirmations, and signed receipts
- Document damaged or missing items with photos
- Record communication with the delivery company
Delivery evidence is especially important when the business claims that goods were delivered as agreed.
Step 7: Proof of Payments or Refund Requests
Financial documentation proves you have already fulfilled your obligations. This can include:
- Bank statements showing transfers or checks
- Credit card statements
- PayPal or other online payment platform confirmations
- Copies of refund requests and responses
Step 8: Attempted Resolutions
Courts favor claimants who attempted to resolve issues before filing. Evidence of good-faith efforts includes:
- Demand letters requesting payment or correction
- Emails negotiating resolution
- Records of phone calls (written summaries are sufficient)
This demonstrates that you tried to solve the dispute without resorting to court.
Step 9: Organizing Your Evidence for Court
Proper organization can make or break your case:
- Create a table of contents for all evidence
- Number each page and reference it in your claim
- Group similar items (financial, visual, written)
- Make copies for the judge, the business, and yourself
Step 10: Common Mistakes to Avoid
- Submitting incomplete or illegible evidence
- Failing to provide proof of payment or receipts
- Overloading the court with unnecessary information
- Relying solely on verbal testimony without supporting documentation
- Ignoring the statute of limitations or filing deadlines
Following these steps ensures that your evidence is credible, complete, and admissible.
Step 11: Special Considerations for Online or Remote Businesses
If the business operates online:
- Confirm the legal entity behind the website
- Keep records of online orders, emails, and digital agreements
- Document attempts to contact the company and request resolution
- Use registered agent information for official service if necessary
Even online businesses are subject to small claims court rules, but documentation is critical to prove jurisdiction and liability.
Step 12: After Collecting Your Evidence
Once your evidence is organized, you are ready to:
- File your claim using the proper legal name of the business
- Serve notice to the business
- Prepare your presentation for the court
Well-prepared evidence increases your chances of a favorable outcome and minimizes the risk of dismissal.
