<p>If there were many potential heirs, I’d say putting kids’ names on the title would be a bad idea. And yeah, it’s possible that future inlaws may cause some trouble. But the OP makes clear that the two children are the only heirs, and that the two houses aren’t the extent of their resources. So … based on my (continuing) experience trying to settle my mother’s estate, I say that what the OP suggests could be preferable to passing a largish estate through Probate.</p>
<p>As prior posters have said, you need a lawyer who is experienced in this arena to assist with your wishes. Good luck.</p>
