Let's say it wasn't a house, it was some family jewelry that the OP gave to her daughter. Would you object to taking precautions that the husband couldn't walk off with half of it, in case the marriage did founder?
As much of a romantic as I am, I see no problem with a parent saying, "I am going to give you a gift, and I want to make steps that this gift is always yours, come hell or high water." Otherwise, I think one would be objecting to nearly all premarital financial planning, since that should always consider what happens if the marriage ends, as much as we hope it doesn't.
I would be very upset if I gave my child something as expensive as a home, to ensure her security, only to find her (let's say) cheating, abusive soon-to-be-ex was going to end up with at least half of it, and she would be, basically, out on the street. Proper planning is essential, though, to eliminate that possibility.
