- Florida couple Tiffany Score and Steven Mills welcomed daughter Shea via IVF in December 2025
- The couple realized their daughter was not genetically related to them and they have since reached a custody agreement with her “genetic parents”
- “The agreement came from a place of selfless love from all individuals, and I am so truly proud of everyone involved. Our family’s hearts are filled with relief and gratitude,” Score’s sister now says
A Florida couple's IVF embryo mix-up made headlines after giving birth to a daughter last year who is not genetically related to them — and now they are sharing an update after announcing they reached a custody agreement with their child's "genetic parents."
Tiffany Score and Steven Mills delivered baby Shea via in vitro fertilization in December 2025, but they soon discovered their daughter was not from the embryos they had created at their fertility clinic, they have said.
Their family shared new details about their lives through a statement released by Score's sister, Alexa, on a GoFundMe established on the couple's behalf, along with photos of them with Shea.
In the statement on Monday, June 22, Alexa expanded on how Score and Mills had identified the biological parents of Shea and reached a custody deal with them, as previously reported by PEOPLE.
"The agreement came from a place of selfless love from all individuals, and I am so truly proud of everyone involved. Our family’s hearts are filled with relief and gratitude," Alexa said in the GoFundMe update.
Alexa said that the couple continues trying to get to the root of how the IVF mix-up took place and is still attempting to find out what happened with all of their three viable embryos.
"That process involves ongoing legal coordination, medical consultations, genetic testing, and the transport and testing of their last remaining supposed embryo – a procedure that is both complex and costly, with no guarantee of the outcome," she said.
She added, "Your support has allowed them to continue seeking those answers while keeping their focus where it belongs: on loving and raising their sweet girl, Shea. Every act of kindness has helped carry them through one of the most difficult chapters of their lives."
Alexa went on to promise more updates "when the time is right."
Her statement comes shortly after Score and Mills reached a "mutually devised custody agreement" with Shea's biological parents, whose identity will remain "confidential," according to a court filing obtained by PEOPLE.
Score and Mills went public with their story in an effort to locate their daughter's biological parents.
The court filing stated that under their agreement, Score and Mills would retain their rights to continue as permanent custodial parents of their daughter.
Since then, their representatives have told PEOPLE they are seeking privacy for their child and focusing on their relationship with her genetic parents.

Meanwhile, Shea's biological parents are seeking “accountability” and “answers” from the doctor and clinic involved, according to their attorney.
Lawyer Rob Marcereau told PEOPLE that he is expecting to file a civil suit against the Fertility Center of Orlando in the coming months.
Score and Mills sued the clinic last year.
The facility has since ceased operations and pointed clients to another clinic with some of the same staff. They and the doctor, Milton McNichol, haven't responded to requests for comment.
