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

Yes. Under WA law, a sperm donor is not a legal parent unless otherwise agreed in a signed agreement between donor and the intended parents.

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

If there is a signed agreement between donor and the intended parents, a sperm donor will not be able to assert legal parentage.

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

Yes.

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

Yes, some courts have recognized multiple parents.

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

Yes.
