I'm guessing a timeshare foreclosure shows up on credit reports, and in the period between when they figure out you're not likely to pay and when they file for foreclosure, that you're past due on those payments will likely also show up, and I'm sure they'll try to convince you to pay.
The mortgage framing is really the same question - can a mortgage lender get a judgement for loan balance and costs above auction value from someone who didn't sign the mortgage note? Let's say you're transferred a claim to a mortgaged piece of real property through operation of estate law, deed of executor, or even deed from the living owner. Are you somehow obligated for the entire amount of the loan, beyond your desire to not have your interest foreclosed upon?
Talking about social credit reports is a bit of a red herring. If it isn't a valid debt, then it wouldn't be legitimate for someone to add it to the financial surveillance records about you. And yes I know these timeshare operations are quite adept at using extralegal pressure to goad people into doing foolish legally-binding things, but I'm talking about what's strictly legal.
My understanding is that timeshare expenses are like HOA expenses, it's not exactly a contract, it's an encumberence on the property. The owner of the property has duties, whether they want them or not, by virtue of being the owner, not because they agreed to the situation. (Of course, it would hopefully be made clear to you that it's a non-negotiable encumberence before you accept ownership)
> But the disclaimer of interests I'm familiar with mean estate law continues to operate as if you have already passed away - meaning the same dynamic would just land in the laps of your greater family.
There's kind of two options here; maybe someone in the greater family wants it, in which case, their pain. If nobody wants it, I think there's some default end for property with no known heirs, and if everyone disclaims it, that's where it goes.
The person who singed the agreement is dead and there is no estate to sue.
