This would make me VERY nervous if I were a sperm donor, egg donor etc... If someone CAN be recognized as a third parent then eventually they WILL be recognized as a third parent.
It’s just a matter of time before these folks are being sued for child support, I suspect.
It's already happened numerous times, mostly (according to this) in male/female pregnancies. This seems to be a murky area of the law and like you, I suspect it won't be long until sperm donors are appearing before a judge.
“It’s just a matter of time before these folks are being sued for child support, I suspect.”
Actually, it’s already happened, and in at least one case, in Holland I think, the judge ruled a sperm donor was liable! This was a few years ago, and since then there were problems meeting demand, because donations understandably fell off. I believe a lot of places have started passing laws to shield donors from child support suits and protect their anonymity, because otherwise the whole system will break down.
