So Jane Doe tells the Commonwealth of Massachusetts that she cannot care for her twin daughters - by voluntarily placing them in foster care - and then wants to go after the sperm donor for child support and genetic information?
Excuuuuuuuuuuuuse me, but if I recall correctly, legal custody now rests with the state, who has the requirement to go after the legal parent(s) of children in foster care to seek payment of support obligations. If I also recall correctly, the laws regarding children born by sperm or egg donation legally have only one parent if the birth mother was not married at the time of delivery, and if she was married then her husband, even if not the genetic father, is the legal father.
Those laws were passed to prevent confusion regarding bastardty and inheritance claims. Those wishing to "share" the experience with the donor may do so if all parties agree to the plan. However, there is nothing that requires the legal parents to allow the donor to have anything to do with the genetic product of their donation. It's a lot cleaner that surrogate pregnancy, where the surrogatye can at the last minute back out of handing over the child and deal with civil suits for years.
As for the "need" for genetic information from the sperm donor in order to address the childrens' medical care, the state can go after that without exposing the sperm donor's identity or placing the identity at risk of later exposure. It seems strange that the state has not seen a need to seek the genetic information but momma, who has neither legal nor physical custody, wants it - along with financial support.
I'm going to go pound my head against the wall. It wil feel a lot better than trying to undersatand what the heck Jane doe is trying to accomplish.
stay safe.
