Quickest/Best way to transfer ownership?

94 year old Illinois resident with failing health. There’s a distant relative that seems to be interested in the rights. There are 6 or 7 properties, located in two counties, Logan and Hughes. We thought that Transfer on Death documents might be the quickest and easiest. I don’t think the interested family member wants to pay a lawyer. None of the properties are producing, or producing much. If this family member doesn’t take them, we aren’t going to pursue probate on them. I think that the rights will revert to the Surface land owner after a period of time?
