Mother wants to move to Texas. We have 50/50 rights

I agree that you may wish to discuss this with an attorney. Has your daughter's mother provided you written notice of her intent to move? That's the first required step. This is not a quick and easy matter to litigate. I agree with the prior post's information about the fact-intensive inquiry as to what is in the child's best interests. To answer what your chances are is tough. As with most family law issues, the best answer is, "It depends." It really depends on why your ex has moved much, what your situation is, as well as the statutory factors referenced in the prior response. Many attorneys offer free consultations, and this is certainly an issue with which a free consultation could benefit you. If you and your child's mother were divorced, this entire procedure (called "removal") is contained in your final divorce document called "findings of fact, conclusions of law and judgment of divorce." If you do not have a copy handy, you can obtain it from the clerk of courts office. Good luck to you.
