Someone else cashed a money order that was in my name. How do I get this taken care of?

Fraud is both a civil and criminal concept. Fraud is actionable if certain elements of proof are established by the evidence. Using the written documentation you have is a good place to begin. Contact a local lawyer - many may give you a free consultation for an hour - to discuss your specifics. Far too many variables exist in the short post you wrote for any further observation by me. Good luck to you. NOTE: This answer is made available by the lawyer for educational purposes only.
