How do I get my personal property back from my ex-boyfriend.

Was your letter sent by certified mail, return receipt requested, or by FedEx, or by messenger, or by registered rPost email (www.rpost.com), so you can prove he received it, and so he knows you're serious? If he doesn't comply, you may have to sue him in Small Calims court for "converting" your personal property. Disclaimer: I'm only licensed in CA. Please note that this answer does not constitute legal advice, and should not be relied on, since each state has different laws, each situation is fact specific, and it is impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue. This answer does not create an attorney-client relationship. '

Send him a certified letter, return receipt requested, detailing each item you want returned, and where and when you want them returned. If he does not comply, file suit against him in Magistrate Court in the county of his residence. Being served with the suit will probably result in the return of your items.
