This would involve sales agreements/title transfers in both PA (for your house) and NC (for the timeshares). That means you'd also likely be subject to transfer taxes for both, as well as the fees for recording new deeds. It can be done, but it won't be simple or inexpensive.
A question for you: how was this reflected in your divorce/separation agreement (if you were married)? Your divorce order from the court may incorporate the terms of your property settlement. If you weren't married, how was the property titled: were you joint tenants or tenants in common?
If you have to go through the sale from you to your ex to get the titles cleared in any case, you might want to consider putting one or both of the timeshares up for sale and getting your name removed that way (when the buyer takes title).
Have you considered how the properties would be distributed in the event either of you should die?
Because of the many aspects of this situation, you might want to consider going to the Blair County lawyer referral service to get a free or low-cost initial consultation with an attorney who could review your deeds, any divorce documents or cohabitation agreements, and timeshare contracts to give you a completely accurate view of your situation.
