Does that matter? Would it matter if she wanted to give it to breast cancer research, or any other worthy recipient?
Again, this isn’t a black and white issue. Remarriages when there is previous family is always difficult. If the poster of the OP went into the relationship fully knowing that she intended to provide for her grown son, then he’s got no gripe coming. But if this is a new development, that’s another matter.
Again, I’m not saying she’s wrong for wanting to help her son. But she has a responsibility to her husband as well, and he has a right to have a say in the disposition of joint finances.
It seems to me there an overriding issue here that’s potentially much more difficult - she doesn’t trust her husband to do what she sees as being the right thing. Or conversely, he thinks she is being overly generous to her son. Again, we don’t have the information to know what’s ‘right’ here. If her son is a layabout who refuses to hold down a job, has criminal behaviours, a drug/alcohol problem or a track record of being horribly irresponsible with money, then I’d say the OP has every right to demand that his share of their joint property not go to him.
On the other hand, if the son is a good person who is just not capable of earning a good income for whatever reason, and she wants to ensure that he’s cared for, then he’s being selfish for denying her wishes because he wants the money. But we have not been told anything about what the son is like or what has gone on before.
So once again, I think people in this thread are issuing moral pronouncements without having the facts.
As an aside, what are the legalities around this in the event of divorce? As I understand it, retirement packages are considered assets in divorce cases. If he builds up $100,000 in retirement income, and she builds up $100,000 in retirement income and they divorce, it would normally be a ‘wash’ and they’d each just keep their retirement packages and go their own way. But what if she’s declared half of hers to go to someone else? Now is it the case that she’d only have $50,000 in assets, and he’d have $100,000, so he’d have to cough up another $25,000 for her in a divorce? Or does the beneficiary not matter because she’s still alive, so it would still be an even split?
Let me point out another way in which this would be unfair - if they both die, their joint assets would be divvied up among the living family members absent a will. Let’s say he had a son from a previous marriage who wasn’t a co-beneficiary of his policy. How would that money be split amongst the two sons? Would the one who is a beneficiary get $50,000, plus half of the remainder? That would be unfair to the other one.
It’s not a simple issue.
