There is simply no "one size fits all" answer to this question...
The deed has a termination date. What happens at that date?
At that point is the timeshare deeded week over?
Do timeshare maintenance fees stop at that point?
You might want to take a look at a current thread over in the "U.S East Coast" forum in a thread whose subject includes FoxRun; it's in large part an ongoing discussion about "termination". RTU contracts (which are not actually "deeds" or "ownerships" in the first place) will, by definition, instead have a
contract expiration date.
There are underlying, officially recorded documents (CC&R's / Declaration) for U.S. timeshare facilities that contain applicable "termination" details. Every place is different regarding what will happen in the "sunset" year, as well as different procedures, required minimum owner vote percentages to make changes, different "default" actions inherited in the absence / failure of sufficient numbers and / or timely voting, etc. In short, there is just no universal, one size fits all answer or standardized, pre-determined course of action. That's just life on Planet Timeshare. Details can be (and often are) very different at different places; it's all addressed within the officially recorded CC&R's for an
individual property.
A deed may
refer to the "sunset" year of the property as a timeshare, but a deed does not
determine (or influence) the sunset year of a property as a timeshare.
Is your "deed" actually instead a RTU
contract, such as those for all Mexican timeshares?. As per above, termination details for
deeded ownership facilities in the U.S. are found within the officially recorded CC&R's / Declaration for a facility, whatever it may be. Generally speaking, there is usually a separate and distinct section or chapter within the resort's CC&R's / Declaration entitled, appropriately enough,
Termination.
There are numerous deeded ownership timeshare places in SW Florida, first built in the early-mid 1980's, with "sunset" years between CY 2020 -- 2025 (usually 40 years after initial construction, at least in that geographic area). Some of these places are wisely tackling the "sunset date" issue
now, well in advance of the "sunset" year.
Others still have their heads in the sand, either denying or delaying the irrefutable need to confront, resolve and record the legalities of this issue, one way or another.
