US SB230

Amends the Social Security Act to require states to establish and enforce child support obligations from biological fathers for unborn children, with payments potentially beginning from the first month of conception as determined by a physician

Support obligations may be retroactively collected even when paternity is established after birth, with payment amounts determined by a court in consultation with the mother based on best interests of mother and child

Defines "unborn child" as a member of the species homo sapiens at any stage of development carried in the womb

Prohibits paternity testing without the mother's consent and bars any paternity measures that pose risk of harm to an unborn child

Takes effect 2 years after enactment and restricts federal waiver authority to prevent states from opting out of these child support enforcement requirements
