Legal Question in Family Law in Texas

It depends. The law provides very strict and very specific circumstances when a third party has standing to interfere in the parent-child relationship. Having standing to file the lawsuit is the first step. "Bad" will then have to be defined and supported by evidence. Many attorneys provide a low-cost first consultation - consider having one review your information and allegations and evidence and discuss whether you are able to take action; and if so, what the cost would be. Good luck.
