Sorry this happened to you. Unfortunately its more common than people realize. Here's your action plan:
1. State Contractor Board Complaint (do this FIRST)
If he's licensed, file a complaint with your state's contractor licensing board immediately. This is often more effective than court because:
- Boards can suspend/revoke licenses
- Many states have contractor recovery funds for exactly this situation
- If he has a surety bond (required in most states), you can file a claim against it
2. Small Claims Court
$15K is within small claims limits in most states. You don't need a lawyer. Bring your contract, proof of payment, all communications, photos of incomplete work. Even if he doesn't show up, you get a default judgment.
3. Police Report
File one. Taking money with no intent to perform the work is theft by deception in most jurisdictions. Police often say "its civil" but file anyway - it creates a paper trail and sometimes prosecutors do pursue these, especially if he's done it to others.
4. Check for Other Victims
Search his name and company on local Facebook groups, Nextdoor, BBB complaints. If there's a pattern, a prosecutor is more likely to get involved and you might have grounds for a class action.
