Paternity registries

NY Times:

Under Florida law, and that of other states, an unmarried father has no right to withhold consent for adoption unless he has registered with the state putative father registry before an adoption petition is filed. ...

While women have the right to get an abortion, or to have and raise a child, without informing the father, courts have increasingly found that when birth mothers choose adoption, fathers who have shown a desire for involvement have rights, too.

But to claim those rights most states require a father to put his name on a registry. While about 30 states now have registries, they vary widely.

I never heard about those registries, the article explains that they are ineffective.
