Q: My Aunt’s property was left to a nephew and his wife and family. Other family members have been talking to the aunt who has dementia and now she has changed the will. Is this legal? (Pittsburgh, PA)

A: Your aunt can only change her will by executing another one, a new will, which is in compliance with the law. Plus, she can only execute a new will if she is competent. Dementia does not necessarily mean she is incompetent. There are varying degrees of dementia. If she executed a new will and you are suspicious of the circumstances, you should review all the facts with an attorney.
