Hi, i have a situation with an ex-girlfriend from 5 years ago and a joint bank account in which her name is still attached. Well, I haven't heard from the girl in 5 years and theres was a general understanding when we split that the bank account would remain in my use since i had alot going on with it, and still have over the past several years, using it mainly to deposit my weekly pay as well as pay bills, etc...regular stuff. Last week I began noticing odd transactions so I investigated further and discovered that my ex had resurfaced and began making withdrawls from my account as well as payments to her credit cards using my money. I have been in contact with her via email to attempt to recover this money to no avail. What are my legal options to recover the money she obtained?
