History
The Intersection of Family Law and Surrogacy Agreements
Quick fact
In many U.S. states, a surrogacy contract is unenforceable if it pays the surrogate beyond medical expenses, because courts view it as 'baby selling'—yet in California, surrogacy is broadly permitted and parentage is determined by intent, not biology.
Why this is interesting
Imagine signing a contract to have a child for someone else—only to find out that contract may be legally meaningless. In surrogacy, the law often steps in to decide who is the real parent, and the answer isn't always in the agreement.

Understanding The Intersection of Family Law and Surrogacy Agreements
Surrogacy involves three parties: the intended parents, the surrogate (or gestational carrier), and usually an egg or sperm donor. In traditional surrogacy, the surrogate is also the egg provider, so she is genetically related to the child. In gestational surrogacy, the surrogate carries an embryo created with the intended parents' or donors' gametes, so she has no genetic link. The central legal question is: who is the legal parent? Family law normally determines parentage by biology (the woman who gives birth is the mother) and by marital presumption (the husband is the father). Surrogacy disrupts this because the birth mother may not intend to raise the child, and the genetic parents may not be the birth parents. To resolve this, courts often rely on a surrogacy agreement, but the contract alone is not always sufficient. The most reliable path is a court order before the birth (pre-birth order) or after (post-birth order), which legally names the intended parents. In many jurisdictions, the surrogate must also formally relinquish her parental rights after birth, and that consent is frequently revocable until it is given in court. Thus, the agreement is not a simple contract; it must align with family law doctrines and public policy.
A deeper explanation
The core mechanism is the legal determination of parentage. In most common law systems, parentage is rooted in birth—the woman who gives birth is the mother, and the father is the husband or the biological father. Surrogacy challenges this because it separates gestational, genetic, and social parenthood. The law steps in to allocate rights and responsibilities, but it does so through two competing lenses: contract law (what the parties intended) and family law (what protects the child's welfare and preserves the integrity of parentage). The conflict emerges because surrogacy agreements often involve payment, which triggers concerns about commodification of children. Many courts and legislatures deem paid surrogacy contrary to public policy, as it resembles baby selling, which is illegal. Consequently, a surrogacy contract may be void or unenforceable if it includes compensation beyond medical expenses. This means the intended parents have no contractual remedy if the surrogate changes her mind. Instead, the surrogate retains parental rights until she voluntarily terminates them in a formal adoption proceeding, and her consent is typically revocable until then. In contrast, some jurisdictions (like California) prioritize intent: if the parties clearly intended the intended parents to be the parents, courts will enter a pre-birth judgment declaring them the legal parents, making the surrogate's consent unnecessary. This shows that the concept is not just about contracts, but about how law defines parenthood in the face of technological intervention. Understanding this helps explain why surrogacy laws vary dramatically by jurisdiction and why disputes can be so emotionally and legally complex.
