My girlfriend lost her father at the age of 6. She lost her mother at the age of 12. Since then, she has been living with her aunt. She recently turned 18 and has moved out. She had a CD that opened up before she turned 18 . The CD had about $5000 in it. Now there is $3000 left. Her aunt made a condition that for her to be a signer on my girlfriend's documents for the apartment, my girlfriend would have to leave that $3000 in a joint account. Without this, she wouldn't have been able to move out and her aunt would charge her an extortionate amount of money to stay at home after turning 18. Now her aunt has moved the money into a private account and has refused to return it. She is also threatening to use the money for her own rent and other miscellaneous things to control her niece's actions. We're both young and don't know what to do, please help.
