My Ex has either withheld or interfered with my visitation of either one or both of my daughters every weekend since the beginning of September. "Interfered" as in, she may drop off several hours late, even after my wife and I have gone to bed or on Saturday when she's supposed to drop off at 6pm on Friday. I'm certain that this is retribution for me moving on with my life, as things got much worse between us when I remarried.

What's the procedure to get this fixed? Do I call the AG? Do I need a lawyer? I'm in Texas if that makes any difference.
