If I exit my timeshare, what happens to the loan attached to it?

Hello there, I have a timeshare in Costa Del Sol and my health has deteriorated over the last few years. I would just like to ask, in the even that I die, what would happen to my timeshare?

My inlaws have a week timeshare in keswick but have been told this year that the week has been repossessed due to non payment of managenent fees as per their contract. However they didnt receive any communication of this as they were not at their home for 18 months which the company were aware of. The fees for 2021 were not paid as there was debate over the amount during covid as they were unable to use their week during 2020 and 2021 (despite 2020 being paid in full). They still want to keep their week and it was a 99year contract held since the site was built. I suspect the company want to resell the week as they now offer much shorter contracts so can make more money out of it but cant prove this. Can I argue the week should not have been repossessed?
