The rules under which Pennsylvania courts determine whether a biological father or some other man should have to pay child support are changing, and even the Supreme Court says future cases will refine the new standards.



The high court on Tuesday said a York County support case needs more information about the boy's best interests, saying a woman's estranged husband isn't necessarily obligated to pay support just because he held himself out as the father.



The majority opinion says courts shouldn't throw out a support claim against a purported biological father without at least bringing him to court as a witness.



The ruling says that “all things being equal” in regard to the supportive relationship between a child and his “psychological” or biological fathers, responsibility lies with the biological father.
