They have stopped making payments.Can my husband and I do a quick claim deed and have the house in our name? We live in Michigan

Does this relate to your other question? If so, please don't start multiple threads for the same issue, let me know and I will merge them.

You need to clarify the situation here. If your son and spouse are buying property on a land contract, then its not a mortgage. Also they do not own the property. A contract for sale doesn't convey ownership until the contract is satisfied. I also don't understand why you put up your house as collateral. In any home purchase, the home being purchased is the collateral, why would anything else be needed?

Also, in a Land sales contract, generally a default converts the contract to a rental lease with all previous payments forfeit. So you need to tell us what is really going on here.

... Can my husband and I do a quick claim deed and have the house in our name? ...

If they are on the title, your son and daughter-in-law would have to sign a quitclaim deed. But, As ScottGem said, you are very unclear as to what the situation is. It's either a land contract or a mortgage, but probably not both.
