Yes he can, according to the Texas Probate Code. A judge can declare that a parent can't inherit by or through a child if the parent abandoned or failed to support the child; abandoned the mother during pregnancy and birth; or, was criminally responsible for killing or seriously injuring a child. Notice that this can happen if the parent abandoned THE child or killed or seriously injured A child. The child killed or injured does not have to be the one from whom or by whom the parent is seeking an inheritance. EC 201.062.

Tell me what happened

This page is general information about Texas law. It is not legal advice about your situation, and reading it does not create an attorney–client relationship. These matters turn heavily on specific facts and specific dates, and the law has exceptions this page does not cover. You should not take, or refrain from taking, any action based on this page.
