So you already inherited this timeshare?
I don't know the rules about inheriting an RCI Acct., but RCI strictly prohibits renting exchanges, so you won't be about to use the deposits for rentals. You can use them for your own vacations, or gift exchanges to friends and family.
*Sometimes, people do rent exchanges to friends or family, "under the table," and if they are careful, they are unlikely to get caught, because they make sure their friends and family understand that they can't disclose that it's a rental.
However, people who advertise RCI exchange for rent on the internet, and rent to strangers, are far more likely to get caught, because their renters may rat them off - either intentionally, or unintentionally. If that happens, RCI can close your account, and confiscate all your fees paid, and deposits, and exchanges - not worth the risk.
I'm not sure how he could make 41 deposits since 2011, unless other timeshares were also deposited in this account?
