IMHO, an automatic DNA match between the baby, mother and (suspected) father should be required at every birth. There are a significant number of men, who are lied to, and are ‘tricked’ into raising a child that they did not father.
If a man decides to take on the role of ‘father’ to a child; this should be done with knowledge that he is, or is not, the biological father. This is one means of doing that.

I think that’s a better plan than the current one, where a woman can name any man in the world as the father on the birth certificate, and he is assumed to then be legally liable for support. Nowadays, men are guilty unless they can prove themselves innocent.
