Does your parent want to do this, or do you want to do this? |
If your parent starts spending their money on a spouse's care, you can make it clear that you won't be able to support for parent should they spend all their money (this would be fine to do if your parents were still married too). |
Of course. The point is, if the parent is married they have the OBLIGATION to pay for their spouse's care, whether that spouse is the parent of their children or not. Maybe their are some legal loopholes like the OP wants, but seeking them out makes them a garbage person. |
They can’t take your house. So you can tie money up in a house.
Look into Life Estate and an irrevocable trust. |
