When I met the father of my children, he already was a single dad to his 7 year old daughter (who is now in her 20's). After we married, she went to see her druggie birth mom and got in more and more trouble and traumatized in some really bad ways - none of which we were aware of at the time because it was out of state. She ended up with a lot of bills that came her father's way for her treatment and legal issues. The girl once came home and said that she didn't have to listen to her father because her mom said he wasn't even her dad. Well, when her father got the bill for many thousands of dollars from the state for all her troubles, it was suggested that they find out if she really was his or not. The DNA test came back and it showed that the woman had cheated on him and he indeed was not the biological father, after all, even though it didn't change much about them being "father and daughter" in general. Well, in a landmark decision, the court actually found in favor of my (now ex) husband and said he didn't owe the fees since he was not the biological father, even though he was on the birth cert and had raised her for a good part of her life. Well, suddenly, the legal system in California was in an uproar, and all these other men fighting the same issues who were unable to win their cases were contacting his lawyer to get the details of the case and try to overturn the judgments against them for children that were not really their biological children. And of course, rather than set a legal precedent and let all these men off the hook, the state had to get their money any way they could, so they reversed the decision and have been taking every penny they can get their hands on from him, and all the others, too. It's just how they roll. Was pretty interesting for a minute there, though, when the courts seemed to finally come to their senses, didn't last.
