I would first start with the divorce decree to see what received title to the timeshare. If you aunt received sole title to it, then she should record a copy of the dissolution decree on the time share for transfer of its title to her exclusively.If the dissolution decree does not place title to the time share in the aunt, then a probate for small estates will need to be opened up in the county and state of the uncle to transfer his interest (1/2) to the the children designated in the Will. I suggest that your aunt consult further with a Wills and Trust attorney about the situation. He or she will need to review the deed to the time share, the dissolution agreement and the Will of the uncle.
