No lawyer in this forum can tell you this. Grandparents rights are very narrow and specific under Texas law. You need an attorney to advise you of your rights.
Brian Tyrone is a licensed Texas attorney. Any answers I provide are not intended to be legal advice, nor do they establish an attorney-client relationship. Because there is no attorney-client relationship established by any answers I provide, you should consult with a licensed attorney in order to understand your legal rights and responsibilities.
