We’ve taken precautions with our kids inheritances in various ways. Trusts and other documents can be creatively drafted that offer protection, along with some flexibility, per your requests, and things can be changed, if necessary, along the way.
Before our kids were married, we discussed this with them, as well as other issues we felt were important to consider wrt marriage, that extended far beyond the financial aspects.
Although they made their own choices, as many parents, we had visions of what we would consider to be appropriate mates for our kids, and, so far their visions and ours have pretty much been the same.
