Yes, you can sue him for breach of contract. In California, you may sue in small claims for up to $10,000, in superior court limited jurisdiction for up to $25,000, and in unlimited jurisdiction for more than $25,000. Breach of oral contract has a two-year statute of limitations, which runs from the date of the breach (failure to pay according to the promise). You may be able to argue that the voice mail acknowledgment started the two-year clock if you lent him the money more than two years ago. You will want to use the voice mail as evidence, but other evidence will help, too. For example, if other people know about the loan or heard him say he owes you money, they can be your witnesses. If he made even one payment to you, that's evidence that he owed you money. You also might write him an email or letter reminding him that he borrowed the money from you, promised to repay you, reaffirmed the promise in his voice mail of whatever date, etc. Also ask him for payment in full. This demand letter and any response by your ex-boyfriend can also help you establish your case. A visit to a local lawyer might be worth your while, to help you draft the letter and advise you about the specific evidence you have. You can sue in your own name, or you can hire a lawyer to sue for you. Hope this helps. Good luck.
