freewill, I think it is worth a try! You have tried letting him manage his own finances and it has not worked. Maybe this more hands-on approach will help him get on track. Just curious--what did you mean about "taking over your son's finances"? Is this an official legal action, or just a mom giving a son some informal help--managing his checkbook, making sure his paycheck goes into the bank, his rent is paid, etc.? It could be your son will resent this interference from mom, and that could actually be a good thing. It might kickstart him to take greater responsibility so that Mom doesn't have to step in and take over. Whatever way you can motivate him, go for it!

There are low cost courses in money management at junior colleges, community schools, parks departments, etc. Maybe son can take advantage so he can learn enough to take back the reins from Mom. I would think that would be very empowering.

Good luck to you and your son.
