Okay, so I'm getting conflicted replies and just want to clear up a couple things.
1) My son isn't forced to work let alone to contribute to the family. This last year we allowed him to fail and he blew every last penny, including his $200 tax return. We figured to try and let him learn the hard way except that idea seems to have backfired and now he's even more greedy, saying that we legally cannot manage his money for him. He promises to stick to a budget so that he can save for a car and does well for a couple weeks and then blows it again. He's not learning and it's highly frustrating. His birthday is in December and we gave him the deadline to have saved half and we'll match the amount but so far it appears that he's not taking things seriously and plans to wait last minute to save? Our jobs as parents is to raise a responsible, independent individual and he's just not having it, it seems. He now has just a little over 4 months to save up for his first vehicle and he doesn't have anything to show for it. In retrospect, it's a lesson learned for us instead lol. Now to get a handle on the situation, my husband put his foot down and is forcing him to save asap.
2) I'm unsure about other states, but here in Florida, a minor does have to have a parent on a banking account with them and that is a joint account until the parent removes themselves from the account once the child turns 18. It is a joint account so we do have access to his income since his pay is direct deposited, so it's not like he can cash a paycheck and keep the money hidden from us. I myself, am able to see what his account activity is at any time including any of his "free trials" for online games that he's signed up for (which I've made him call these places himself to cancel but he's not learning unfortunately). So, my husband has confiscated our sons debit card to manage his irresponsible spending behavior.
3) Our son feels violated and angry that his independence has been taken away, understandably, however now thinks that were only trying to control his budgeting for the purpose of spending his money ourselves, which is simply not true. We did give him the chance to do the right thing but also gave him the chance to learn the hard way, which now he feels "the hard way" is unfair and illegal, which is why I asked here.
I know minors cannot sign into legal contracts and I know that while he is a minor, we have full control over his well-being including setting him up for a successful future and as his parents, we refuse to allow him to grow up thinking he can loaf around, being irresponsible, blowing his money etc. We feel that this is a wonderful life lesson that he will eventually thank us for being tough and adament but meanwhile, I just want to make sure we're not overstepping any laws in doing so.
Per my husband, he would like to see our son follow in his footsteps, obtain a vehicle at 17, be responsible for it (maintenance etc), manage his own finances, work his way up the corporate ladder etc; but our son has hit a horrible time and is rebelling at most every advice we give but is excelling at school and work so that's wonderful. I personally believe that we took the wrong route with allowing him to mess up to begin with. He got that little taste of independence and is now throwing a fit and brought up the legal aspect which had me worried, so here I am. My husband and I refuse to continue being his driver until he's 18, nor do we want to sit back watching him live frivolously while we provide everything else for him. It would be a different story if he wasnt working, earning his own income but he is and he should be able to purchase his own fancy colognes if he wants rather than expecting us to (which we refuse to buy) simply because it's a hygiene thing and we're his parents and legally "have to" lol.
Thank you to everyone whose replied so far. Please, if there's anymore information, bylaws etc that you can share, I welcome all comments.
