Documents for FL resident annual pass

My mom just bought a condo in Florida. She wants to use our upcoming 9 day park hoppers towards a FL resident annual pass. I know we can do this at guest services but I am not sure what documents she needs. She doesn't have a FL driver's license yet but does have documents from the condo purchase and maybe bills. I should add that she only lives in the condo in the winter. Previously she rented but now that she owns it, I think she is eligible for a resident discount.

Somebody was just talking about this couple of days ago on the chat app.. Here is the link
