If deed is still in decedent’s name, and estate has been closed, there is no one who can sign over deed-so no way to transfer back or sell to anyone else. Since deed stayed in decedent’s name, I’m assuming it wasn’t listed in estate. I believe only remedy is foreclosure by the resort for nonpayment of annual fees, SA, etc. Non-judicial foreclosure is also not available where legal owner on title is deceased. Foreclosure, I assume, would be against legal owner on title. There will be a number of bills/collection notices, later a court hearing notice, and then a final disposition notice from court. Process can take 2+ years.
However, If TS was part of estate, what did executor do with it? Was there a report of settlement of estate? If the estate went via probate, were any docs filed with court? If the TS was not disclaimed and it was part of estate, something should have happened to that deed to transfer or disclaim it. If it was not, and it’s still in decedent’s name, I’d think foreclosure per above would occur. But I’d at least contact the estate attorney to inquire what happened.
