If you ever make money while living with them underage, make sure you get a proper bank account! If you have other family that is trustworthy, a grandparent, aunt/uncle, older sibling or older cousin, have them be the custodian of the account if the bank requires one. And talk to the banker about what your options are to protect yourself from your SSN being used by your parents. Your credit could be ruined before you're able to establish it yourself. (It happened to a cousin of mine because his mom was awful.) This is an awful thing to have happen after your grandfather's death. I hope that you're able to keep his memory with you in your heart. 💛 Just make sure that you protect yourself now that you know your parents' true colors.
