Artificial Insemination is mentioned one time in the South Carolina adoption statutes under the Responsible Father Registry statute.  The implication is that a father who consents to artificial insemination continues to have rights to the child and may preserve those rights by filing with the Responsible Father Registry. Section 63-9-820(L) of the South Carolina Code of Laws reads:

An unmarried biological father’s failure to file a claim of paternity with the registry is deemed to be a lack of proper diligence under Section 63-9-770(B). An unmarried biological father’s lack of knowledge of the biological mother’s pregnancy does not excuse an unmarried biological father’s failure to file a claim of paternity pursuant to this chapter. An unmarried biological father’s sexual intercourse or his consent to artificial insemination with the biological mother is deemed to be notice to the unmarried biological father of the biological mother’s pregnancy.

The parent/parents that use artificial insemination with the sperm of a third party to expanded their family will need to terminate the parental rights of the biological father to ensure that his rights to the child are severed.
