Wisconsin

Can a known donor renounce his legal obligations as a parent?

Yes. As long as Wisconsin’s statutory requirements are followed, a donor may renounce his legal parental rights.

What if a known donor attempts to enforce his parental rights when the original intent was to be a sperm donor only?

Unknown; this has not yet been addressed.

Does the state allow for second-parent adoption (i.e., for same-sex couples)?

No.

Does the state allow for multiple-parent families (when the child has more than two adults in a parenting role)?

Unknown; this has not yet been addressed.  (However, a case establishing the rights between a known donor and the child’s legal parents is currently pending before the WI Supreme Court.)

Does the state recognize “de-facto” or “psychological” parentage (of an “acting” parent without a biological connection) or a similar concept?

Yes.
