My mom has insisted that anything I inherit from her stay in my name. I don't know if she's said it in front of my husband, but these conversations always happened with him in the house, so it's not like she's hiding anything.
Her concerns are this:
1. She would like the money to go to me or her grandkids. It's her money, and I respect that.
2. She doesn't like "tying money up in trusts."
3. If I commingle the money, die, and my husband remarries, and dies, then his wife gets the money, and my kids get zilch. This is not as far-fetched as it might sound, and it's a lot of money to be concerned about.
So, since I don't care about my husband's future wife (no offense), and I love my kids, I intend to do as she says. Either way, I'm doing my husband a favor if the kids inherit it, because it's that much less he'll have to give any of them for college, a wedding, or a house. If for some reason he really needs some money, I'll probably write up a will that splits it evenly between all of them.
