Legal Question in Family Law in Texas

Re: Marriage

After very brief research, I did not find caselaw on point. I would advise, however, that the marriage is still legal, and the couple would have to divorce if they wanted to split up. My reasoning being that the state of marriage was a legal entity, and a medical procedure does not automatically reverse a legal process. Additionally, the statutes provide for only three methods of dissolving a marriage - annulment, divorce and death. (and the alternatives under a commonlaw marriage).
