Of course you are correct. However you buy a house and you get a mortgage from a bank. With timeshare you buy a 'membership' and you don't get a mortgage. Membership can be curtailed if the appropriate fees for membership are not paid. Membership, in the case of timeshare, was gained under false pretences by the seller. They promised things at the sale which were not fullfilled. The buyer therefore has every moral right to cease membership. Using the legal system of the country of jurisdiction for the timeshare is morally wrong and the member is unlikely to be found against in court and, in any case, the courts juisdiction does not cover UK citizens in the UK. Even if a UK court were to look at a case it is extremely unlikely a UK court would find in favour of a timeshare company who sold under false promises in a foreign country. UK courts have only looked at cases for UK timeshares or, possibly, european timeshares.
