I am sorry that your memory doesn't extend to the dozens of times that subject has been discussed on these forums.
However, here is a snippet from the website that follows:
"Or, you can open a case with the Office of the Attorney General (OAG) Child Support Division. Although the OAG cannot represent you, the OAG may be able to help you get a custody, visitation, child support (including back child support) and medical support order. For information about opening a case with the OAG, call 1-800-255-8014 or go to its website:
Texas Attorney General Child Support Division. "

And here is the AG's website:

"And here is another snippet from the website that follows:
Most custody orders include a standard possession order (SPO) that sets the schedule for each parent’s time with the child. Custody orders refer to parenting time as access and possession, which is the same as visitation. Terms of the basic SPO allow the noncustodial parent to have possession of the child a couple of hours every Thursday night; on the first, third and fifth weekends of each month; on alternating holidays, and at least one month in the summer. The SPO tells the parents where the exchanges of the child will take place, where the child will spend the holidays, and has special rules for parents who live more than 100 miles apart. The court does not have to follow the SPO if a child is under three years old or if the SPO is not in the best interest of the child. NOTE: Parents with an SPO can agree to any schedule that works for both of them. If they can’t agree, then they must follow the SPO."
If you go through the OAG, child support staff must follow the Texas Family Code presumptions of the SPO

Again, this is a subject that has been discussed on these and other forums dozens, if not hundreds of times over the years. I am rather surprised that you would not remember that.
