Can LA MERP take property that was donated or sold from parent to child before the five year look back 20 and 30 years ago?

No, you are way past the look back period.

Should be ok if the property was properly transferred. If you kept it in the elder name for tax reasons, talk to a lawyer. Was it listed on application for Medicaid? Then it wasn’t sold or transferred to child if it’s not on the tax rolls that way.

Hello, I don’t know what La MERP is, but based on your name “grandisle”, I assume this is Louisiana Medicaid. Every state has different rules, but I can say with some assurance that a property sold that far back would definitely be safe.
