District of Columbia

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

Yes, this is possible under DC law if this is agreed to in writing between donor and recipient.

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

This is unlikely to be successful; in DC, a sperm donor (defined as providing sperm via any method of conception other than intercourse) is not considered to be a parent unless the parties make this clear in writing.

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.

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

Yes.
