Texas law limits the circumstances under which grandparents can request visitation with or file for custody of their grandchildren. In most cases, you must prove to the court that instituting visitation or custody is in the best interests of your grandchildren in opposition to the wishes of the parent(s). This burden of proof is often difficult to establish with certainty, so it’s best to retain legal assistance if you believe this path is necessary, particularly if your grandchildren are in emotional or physical danger. And since timing can be critical, it’s vital to do so immediately.
