KathyPet. I find it hard to believe that you think most of the population discusses inheritance and inheritance planning.
Within the general population, you're probably right - MOST people stick their fingers in their ears, and do NOT discuss the future - they just got past a mortgage and paying for their kids' college, etc. But one can fairly assume - up to a point - that those of us who are making LUXURY purchases - and a timeshare is luxury - would be a little bit more mindful of financial planning. There are financial shows (Suze Orman, Jean Chatzky, Jim ???) and podcasts (Dave Ramsey, etc.) all over now, and you cannot go a week of seeing news on TV or reading a paper, and not hear advice, or a reminder to GET some personal advice. Yes, I know that some people equate financial advice, insurance, etc. with thoughts of their own mortality, and yes, there are STILL some marriages in which only ONE partner takes care of ALL the money. DH and I have lost all four of our parents within the last 3 years now, and were VERY lucky that they left everything very tidy - and they were middle-class working people, none with college educations of professions, just a lifetime of punching a clock. We have only one adult son - and we are very organized, to protect our assets when we are in The Drooling Academy, and for his future - and we TALK about this to him. I say this NOT to sound preachy, but many of us only learn or *wake up* when witness someone else's predicament.
I certainly think that there would be SOME attorney who can help the OP resolve this mess - which has occurred in a time of great grief. Many people at all income levels have "not simple" legal and financial issues, and if the attorney you have is flummoxed - time to get a new guy - PERMANENTLY. If the OP's parents bought one week of a 2BR, let's say at most places this would have been in the wide neighborhood of thirty grand. Perhaps family would all want to *buy in* for a portion of this - taking rotating weeks, etc. If it requires legal advice to sort the mess - then it is going to cost MORE than whatever this place is worth if you sold it - which I why I mentioned a sit-down with family and/or friends who want a slice. TALKING is the key - since there appears so far to be the *possibility* or a mortgage, and selling will not erase that - perhaps keeping it and either RENTING it out, and making a few $$, converting it into points and renting THOSE out, or making a small partnership with family/friends might make this a better deal to KEEP, than to unload. Just my two cents - and there are folks here who know FAR more than I do about the legal stuff - this is just my pragmatic side talking.
To the OP - my condolences on the loss of your Dad - and my thoughts are with you and you Mom and families. But in this case "make haste slowly" - and do not be upset with people who offer all kinds of advice, since many of us have also lost parents, or have friends who did, who left them with ALL KINDS of things to unravel - and they are just thinking fast, or recalling what worked for THEM.
