If they won't pay voluntarily you could take them to small claims court if the amount is no more than $5000, or to District Court if it's between $5000 and $30000. If you had an agreement with them, you would sue on a breach of contract. If you just did it without any understanding with them, you would have to claim unjust enrichment. Consult a real estate attorney for more information.
