The ‘father’ on a birth certificate has always been the second parent with legal responsibility for the child.
’Father’ has never really meant biological father - if a separated woman has a baby with a new male partner whilst still legally married to her husband, her husband is the second parent with legal responsibility (this caused a massive headache for my US born, UK resident friend and her daughter’s ability to prove her entitlement to a British passport via her bio dad, because legal dad was not British 🙀)
Years ago a baby’s nationality was determined by mother only because the ‘woman a baby came out of’ is far easier to objectively ascertain than who the biological father is (pre DNA).
If a married/civil partnered couple (F&F) have had a baby via an anon sperm donor then surely the wife of the mother has just as much right to be in the ‘second parent with legal responsibility’ box as a F&M couple who used a sperm donor due to male infertility?
personally, I think birth certificates should provide the baby with as much factual information as possible and if that means adding some extra boxes then so be it (I am very anti surrogacy but as it can’t be eradicated and the baby deserves the info then perhaps extra boxes are necessary to keep up with tech)
I absolutely do not agree with erasing the names of lesbian women from the already-existing birth certificates of their children - those women took on the legal second parent role in exactly the same way the man in a straight couple using a sperm donor did.
If Italy want to change the way legal parental responsibility is recorded in future by adding extra boxes so be it but most sperm donation is anon until the kid is 18 so the ‘father’ box cannot contain any useful info anyway 🤷♀️
it’s already obvious that a female second parent isn’t bio dad so having a blank ‘father’ box and adding an extra category doesn’t actually tell anyone any more than was already obvious!
And presumably non-anon donors (eg a friend of the couple) can’t be recorded as ‘father’ without also having some unwanted legal responsibility conferred?
Raising children requires a lot of resources and two willing and able adults should be able to share legal responsibility regardless of whether parent two is a biological parent or not - anything that removes the ability of female-female couple to make that legal agreement will ultimately be a negative for the children they are raising - the child will have less legal security and likely less psychological security too.
(the complex issues around gamete donation is a subject for another thread 😬)
