Was it as simple as just a call?
You removed your husbands name before divorce and added yourself?
Sorry, it's more than just a call.
First the deed needs to be amended, changing the list of owners, and the deed needs to be filed with the correct governmental agency (Orange Co. FL, if a WDW resort, different place if VB, DHHIR, AUL, VGC).
Once the new deed has been filed, then a copy of the new deed needs to be sent to
DVC along with a form giving the new owner's contact information and certifying that no money or anything of value was paid for the ownership.
Then DVC will change their records, and the new owner will get access to the member website, etc.
Edited to add - that's why we used LT Transfers,
https://www.lttransfers.com/, to do it. Many others have done it themselves, however, without any problems.
