No, you are not legally required to inform her. You are kind of setting up your purchaser for a world of problems, however. You may have a great deal of difficulty finding someone willing to purchase your share, under these circumstances, as well. Depending on the wording of the deed, whatever share you "sell" may evaporate, if you pass, before your sister. Someone would need to review your deed, to be sure.
