We have already established in previous posts on paternity that the state of Texas takes a very proactive stance. The reason for that is the desire on the part of the government to be sure that a child's needs are being met and that the parents of the child are picking up as much of the cost of meeting those needs as possible.
Government loves acronyms. You've got your POTUS (President of the United States), your SCOTUS (Supreme Court of the United States), FBI and CIA. In Texas we have the DSHS (Department of State Health Services) and TxDOT stands for the Department of Transportation. One that is regularly used at the OAG (Office of the Attorney General) is CSRP; which stands for Child Support Review Process.
The good of society in Texas and the United States as a whole is supposed to be maintained by the exercise of the rule of law. That goes for all the different facets of life in which individuals interact with each other. Family interactions are no different.
When the parents of a family break up the relationships that are affected are not limited to just those of the two adults. Children are involved and they have a stake in how the break-up plays out.
Every child born has a biological father. Not every child born has a legal father. In Texas, the prevailing view that seems to be the foundation of the law around paternity is that every child benefits when a legal relationship is established with both the mother and father.
