Florida IVF Mix-Up Case Ends in Custody Agreement Between Mills, Score and Biological Parents

 In Florida, a highly unusual and emotional custody case involving an IVF mix-up has reached a new turning point after court documents confirmed that a Florida couple and the biological parents of their daughter have entered into a mutually agreed custody arrangement, bringing a measure of resolution to a situation that has drawn national attention and raised complex questions about modern reproductive technology.

Steven Mills and Tiffany Score, a Florida couple who underwent in vitro fertilization after struggling with infertility, initially believed they had welcomed their biological child in December 2025 after a long and emotionally difficult journey through assisted reproduction services that included embryo transfer at a fertility clinic in Orlando before genetic testing later revealed a shocking mismatch that changed everything they understood about the birth and prompted legal action against the clinic involved.

According to court filings and statements from attorneys, the couple discovered through genetic testing that the infant they were raising was not biologically related to them, leading to immediate confusion, emotional distress, and concerns that another embryo belonging to them may have been implanted in a different patient during the IVF process at the Fertility Center of Orlando.

In newly filed documents, attorneys confirmed that Mills and Score reached a mutually devised custody agreement with the child’s biological parents, whose identities remain confidential under the terms of the filing, signaling a structured legal resolution aimed at balancing parental rights, emotional bonds, and the complex circumstances surrounding the embryo transfer error.

Despite the extraordinary circumstances, the couple has emphasized that their emotional bond with the child remains unchanged, noting in public statements that they have formed a deep parental connection and intend to continue raising the child while cooperating with all parties involved in a respectful and stable arrangement moving forward.

The case has also drawn widespread public attention as it raises broader questions about IVF clinic oversight, medical safeguards, and accountability within assisted reproduction services, while the couple’s separate lawsuit against the fertility clinic continues to move through the legal system in Florida. Attorneys say the matter is expected to continue unfolding in court as both families seek clarity and long-term stability for the child at the center of the dispute.

Family representatives have expressed appreciation for privacy and cooperation between both parties, noting that despite the unusual nature of the case, all involved have worked toward a peaceful resolution that prioritizes the well-being and privacy of the child above all else. They also emphasized that ongoing communication between the families has remained respectful and focused on the child’s long-term emotional security.

Ultimately, the case represents a rare and complex outcome in modern reproductive medicine, where emotional bonds, legal rights, and biological origins intersected in unexpected ways, leading both families to reach a structured custody arrangement that prioritizes stability, privacy, and the long-term well-being of the child while allowing the legal process to continue in a more coordinated and respectful direction going forward under court supervision as all parties continue moving toward resolution together
