i don’t believe we should be making parents take DNA tests before registering births, it should be accepted that the woman who gave birth is the mother and taken on trust that the man who shows up to register the birth is the father as before.
If, for example, a woman falls pregnant as a result of a drunken shag on holiday and can barely remember the bloke, we can’t really expect the father can always be traced.
However the goal should be mum and bio dad.
Now that fertility ‘treatments’ are available, where doctors implant one woman’s egg inside another woman, it messes things up.
Perhaps the woman’s medical records from the fertility doctor should keep the details of the woman’s whose egg it is and details of the man whose sperm it is and these documents must be brought along to register the birth.
It wouldn’t look pretty, but the child’s birth certificate would be:
Mother: She who gestated and gave birth.
Father: Man who comes along to be registered as father
then have an additional section, headed by words to the effect of ‘medically implanted pregnancy’ and underneath:
Genetic mother: Woman whose egg was used
Genetic father: Man whose sperm was used
That way the child has a proper record of who they are.
