Bumpitybumper I said she 'also'wanted the kids. As in aswell as him. Because you were talking about him choosing kids and him benefiting from her being a sahm/working part time. She is also benefiting.
I get the loss of earning power. But if you attach monetary value to bringing up you own kids, you have to attach monetary value to the person bringing in more money and working more hours.
No one ever says a dad is providing free
Child care are when he watches the kids.
I get the OP wanting the fact that her career is slower, recognising in the event of divorce. Even though that's a choice she made, knowing the impact. But no, I don't agree providing free childcare should be included in a divorce, because the other persons will be contributing more in that situation too. Just in a different way.
In the ops case, I can not believe this hasn't been discussed before. Especially since the money comes from 3rd party. The dh should have been clear his parents investment would always been protected if that's what he and the parents wanted. The op shouldn't have assumed she would automatically get 50% of the gift from his parents. Especially when they were not married at the time this happened.
If I gifted a large amount of money, to my child, I would want it protecting. But that would have been made clear and if he had valid objection, I wouldn't insist on it.
Op since you earn decently and work almost full time, there's a good chance you wouldn't get to keep the all of the house. You may not even be able to stay in it till the kids are 18. That's not a given anymore.
This isn't just about you and your husbands financial contribution to the marriage. And I think that's where the problem is. This is also about a 3rd parties investment.
If you invest more in the future, yes you can have another deed drawn up. It's not like something you will be doing every year. Only his initial investment should be protected, and your 10k and then equity after that should be split.
Again, I am not saying you should sign. That's your choice.
You could do it after, however if I wanted my investment protecting I wouldn't exchange until I sorted this issue.
