In Maureen Kass v. Steven Kass (1998), the Court of Appeals of New York in Albany, New York, ruled that the state should generally consider IVF consent forms signed by participants in an in vitro fertilization (IVF) program valid, binding, and enforceable in the event of a dispute. The court indicated that decisions regarding the handling of cryopreserved pre-zygotes, often called preembryos, contained within these consent forms should be upheld. Although Steven and Maureen Kass had signed IVF consent forms agreeing to donate unused preembryos to research, during their divorce Maureen argued for custody of the preembryos. The New York Court of Appeals ruled in favor of Steven Kass and concluded that the informed consent forms signed by the former couple had clearly manifested the coupleÕs mutual intent to donate any preembryos to research in the event of a dispute.

The New York Appellate Court ruled on 11 December 1977 in favor of Steven and Hetty Park and against Herbert Chessin for the wrongful life of the Parks' child. In a wrongful life case, a disabled or sometimes deceased child brings suit against a physician for failing to inform its parents of possible genetic defects, thereby causing harm to the child when born. Park v. Chessin was the first case to rule that medical personnel could be legally responsible for wrongful life. Further cases such as the 1979 case Berman v. Allan and the 1982 case Turpin v. Sortini similarly dealt with the legal challenges inherent in wrongful life suits.

In Davis v. Davis (1992), the Supreme Court of Tennessee decided a dispute over cryopreserved preembryos in favor of Junior Lewis Davis, who sought to have the preembryos destroyed over the objections of his former wife, Mary Sue Davis. The decision in Davis, although not binding in other states, suggested a framework for resolving similar disputes in the US. That framework established that courts should follow the wishes of those who contribute their sperm and egg cells, or gamete providers, to create preembryos. In the event of a dispute, courts should enforce any prior agreement between the gamete providers and in the absence of such an agreement, the court should weigh the interests of the parties, ordinarily ruling in favor of the party who wishes to avoid procreation.

In a dispute over the allocation of cryopreserved preembryos, the Supreme Court of Washington resolved the case of David J. Litowitz v. Becky M. Litowitz (2002) by reaching a decision that neither party wanted. David Litowitz sought to find adoptive parents for two cryopreserved preembryos created during his marriage to Becky Litowitz when the couple was attempting to have children using in vitro fertilization (IVF). Becky sought to implant the preembryos in a surrogate in an effort to parent a child. In June 2002, the court instead determined that the preembryos should have been destroyed. The court focused on the former couple s written consent agreement signed at the time of their participation in the IVF program, which stated that the preembryos would be destroyed after five years of storage.

The Supreme Court of New Jersey decided the case of Berman v. Allan on 26 June 1979, brought by Shirley Berman and Paul Berman and their daughter Sharon Esther Berman against Ronald Allan and Michael Vincent Attardi, Shirley's physicians. The court dismissed the Bermans' claims for what they termed wrongful life of their daughter, but allowed them to claim compensation as a result of what was termed wrongful birth. In doing so, the courts ruled that doctors and other healthcare providers were potentially subject to legal and financial consequences if they failed to inform their patients during pregnancy of possible birth defects. The Berman case, along with the 1982 California Supreme Court case Turpin v. Sortini and the 1977 New York Supreme Court case Park v. Chessin, was a case where a state supreme court grappled with the issues of wrongful birth and wrongful life.

The Supreme Court of California reversed the Superior Court of Fresno County's decision to dismiss the Turpins' claims in the case Turpin v. Sortini on 3 May 1982. The case was based upon a wrongful life claim, in which a disabled child sues physicians for neglecting to inform its parents of potential genetic defects, resulting in harm to the child when it is born. The Turpin case determined tha a physician could be liable for failing to inform parents of potential birth defects in the fetus. It further concluded that a minor has grounds to sue for medical malpractice committed when it was an embryo or fetus.

In Gonzales v. Carhart (2007), the US Supreme Court held in a five-to-four decision that the 2003 Partial-Birth Abortion Ban Act passed by the US Congress was constitutional. Although the Court previously ruled in Stenberg v. Carhart (2000) that a Nebraska law that prohibited partial-birth abortions was unconstitutional, Gonzales reversed this decision. Gonzales created the precedent that anyone who delivers and kills a living fetus could be subject to legal consequences, unless he or she performed the procedure to save the life of the mother.

In Stenberg v. Carhart, the US Supreme Court ruled on 28 June 2000 that a Nebraska law banning partial birth abortions was unconstitutional. Though the US Supreme Court case Roe v. Wade in 1973 had set a precedent that constitutionally protected abortions, some states established limitations on certain types of abortion procedures. When NebraskaÕs state government criminalized partial birth abortions, physician LeRoy Carhart challenged the constitutionality of the case. Don Stenberg, an Attorney General located in Lincoln, Nebraska, represented the state of Nebraska. Stenberg determined that states could not create undue burden on womenÕs right to terminate their pregnancies, and that specific restrictions on abortion procedures must include an exception to protect a womanÕs health and life.

In the case Randy M. Roman v. Augusta N. Roman (2006), the Court of Appeals of Texas followed courts in other states and upheld the validity and enforceability of in vitro fertilization (IVF) consent agreements. The Romans, a divorced couple, each sought different outcomes for their cryopreserved preembryos created during their marriage. Randy Roman sought to have them destroyed, and Augusta Roman sought to implant them in an attempt to have biological children. The Texas court, citing several related cases, declared that the written IVF consent form the Romans had signed would govern the outcome of the cryopreserved preembryos.

In the 2008 court case In the Matter of the Marriage of Dahl and Angle, the Court of Appeals of Oregon upheld a written in vitro fertilization (IVF) consent form signed by Laura and Darrell Angle, who had each contributed their genetic material to the creation of several preembryos during their marriage. Its decision followed the general framework for resolving such disputes provided by the Supreme Court of Tennessee in Davis v. Davis in 1992, which was subsequently followed by many courts across the US. The decision by the Court of Appeals of Oregon reinforced the idea that agreements that reflect the couple's intent at the time of undertaking IVF should be upheld, regardless of a later change of heart.
