I believe the mother on the show should be held responsible. I also believe that her ex-husband, Enrique, should have the right to sue her for at least 50% of the child support that he has paid over the years. However, the mother should have the right to find the biological father and hold him responsible. If the biological father knew he had a child with her, he should be forced to pay. If she victimized and deceived him as well, he should only be forced to pay for the next few years of child support, when his daughter is 18.
I was sorry to see attorney Gloria Allred take the wrong side on this issue. I normally agree with her on issues, but not this one. She was wrong. The victim was Enrique and her daughters. The mother victimized her entire family by deceiving and lying to them. Unfortunately Enrique didn't handle the situation well after he found out the news, but that is another matter altogether.
