I said 'a bio dad claiming fatherhood would not automatically nullify a social father's claim to fatherhood' is a rule I am proposing. It is not a claim that a bio dad would never try to claim fatherhood.
Frankly speaking, Jokodo, I owe you shit. We both agree the Finnish law resulted in an unjust outcome, yet you haven't challenged anybody else who also does not support the outcome of the Finnish law (like laughing dog) to draft a family law act, nor have you challenged people who do support it as to why they support an unjust outcome.
I answered multiple scenarios from you and I laid out the principles of what I would consider to be central to family law legislation. But since you are so interested in my opinion on the matter, as a courtesy to you, I will give you my thoughts on your scenarios.
- John and Mary have an open marriage. That means, John knows and approves that Mary occasionally hooks up with Tom, under the strict provision they always use condoms. One day, Tom and Mary's condom breaks, which she immediately confesses to John. When later they learn Mary is pregnant all three sit down on a table. They know there is a chance that Tom is the father, but decide to just assume John is and never go through the complicated route of having a paternity test, and having John adopt the child should it be Tom's - and more than anyone else, Tom is happy about the arrangement as it gets him off the hook. Years later, Tom secretly has a paternity test done, finds that he is indeed the biological father, and decides to use that knowledge to extort money from John and Mary, knowing that going to the court he could easily undermine John's relationship with his 10-year-old daughter.
What's the problem?
What's Tom going to court for? To be identified as the bio father? I don't see a problem there. He
is the bio father. Of course, in your scenario,
he wants to be off the hook. So, he isn't going to do anything that puts him on the hook, is he?
Are you worried about the power Tom has over John and Mary? Why? Revealing he is the bio father isn't anything that requires a court system. He could do it over Facebook. He could take out a full page ad. It would not be illegal for him to reveal he is the bio father. He bloody well is the bio father. John and Mary made the decision that Tom might be the father so they already know he might be the father.
Or has Tom changed his mind, and wants...what? Visitation rights? Well, John and Mary can negotiate that with Tom. And if they can't, Tom can go to court to sue for visitation. Since he is the bio father, I do not see a problem with the court granting him visitation rights. In fact, it seems nice that he has changed his mind about abandoning his offspring.
I do not understand what you think the problem is here.
- John and Mary want children, but John is infertile. Instead of shelling out 1000s or 10,000s of $ to fertility clinics, they decide to help themselves by more traditional means: Mary hooks up a few times with Tom, a mutual friend they trust, until she gets pregnant. Tom has agreed to the terms that he's acting more or less as a sperm donor, but none of this is recorded in writing or notarized. Five years later, John and Mary are pretty broke and decide to go after Tom for child support.
John and Mary get nothing. Tom agreed to be a sperm donor and that's all he agreed to. If you are saying 'but the problem is the evidence', that is nothing unique to family law. It would have been better for Tom to have made the agreement in writing, but contract law does not hinge on something being in writing, only that it was agreed to.
