If you were giving your children large amounts of money, would you try to protect it from being taken in a marriage split?

I inherited a decent amount of money and I want to give it to my kids, my oldest is married and has a family. A year ago I suggested buying a house (I wouldn't be playing for the entire house, there would still be a, mortgage), it would be in a trust so his wife wouldn't own it. It caused a huge drama, so I just left it. I was thinking of buying a house and renting it to them cheaply instead, though it would be held in a trust for my son and in his and his children's names, not his wife and her children from a previous relationship (both had children to previous relationships). I don't want to cause any stress, I don't really know what to do. I know they don't have the best relationship and probably won't be together forever. The only other thing I can think of is just leaving all the money in the trust for down the track, but I know they would love to buy a house.
