There are laws in Belize that govern time-share ownership. I don't know how you will fare if you haven't met your side of the contracts which one owner stated - missing payments 3 times in a row. Although some may argue that they did not receive a bill, it is often in contracts that the owner should be aware of their billing cycles and make payments regardless of whether they receive notices. I am unfamiliar with the time-share contract but would suggest that one of you engage a Belizean attorney and know your rights. I hope you will all receive what you are owed.
