How can I best retroactively “budget” for a sizable purchase (car) I’ve just made? I accidentally put money I intended for savings into my investment account. Should I move it back into savings instead? Should I add my name (become a joint owner) on my aging parent’s bank account(s)? What do the adult children of aging parents often not understand until it is too late? Is there anything I need to know about my parents’ trust or just that I’m the beneficiary? How would I go about moving my investments from active management to managing them myself?
