<prompt> Human: Hi. So I turned eighteen recently and my dad still wont let me have access to our joint account used for my savings. He keeps telling me that he wont give me the account information because Im not old enough to make my own decision.I really want to move it into a personal account, so I wont have to transfer a huge sum of money to my personal account when Im older.My name is on the joint account. Despite that my dad doesnt want me to access my own money, can I still access it and transfer the money to a new personal account if I give my information to the people at the bank? Will they be able to find the account?Also, in the case that I do transfer all of the money to a personal account, would I have to file a 8300 form with the IRS? Its around 15k.Im going to the bank today with my social security card and ID in hopes of being able to retrieve access to it, but in the case that I cant... Well, I dont know what to do.Update: Talked over it with my dad. All good now. Thanks!  <response>: This is more rrelationships than rpersonalfinance, but Ill answer the questions about what you can do. If you go into the bank with your drivers license and maybe one other form of ID, then theyll look up the account number, give you any information you ask for balance, etc., and give you full access to the money. You can transfer it to another account or theyll hand it all to you in cash if thats what they ask you to do.You dont have to file anything if you transfer it electronically to another account. Youll fill out form 8300 if you move more than 10k in cash. But that doesnt hamper anything. You just fill out the form and it gets filed. You wont have to pay extra taxes or whatever.Are you sure theres 15k there? Ive seen situations like this pop up before and it turns out that the parents have been dipping into their childs savings over the years and theyre ashamed to have squandered the money and are hiding that fact.
