Michael Kantaras

Michael John Kantaras (born March 26, 1959) is an American trans man who was involved in a high-profile child custody case with his ex-wife. The case had implications for the legal status of transsexual marriages and the legal definitions of "man" and "woman."

Kantaras was born in Youngstown, Ohio. In the late 1980s, Kantaras underwent hormone treatments and two surgeries at the Rosenberg Clinic in Texas to remove breasts, ovaries, and the uterus, but retained external female genitalia. Kantaras married Linda Forsythe in a civil ceremony on July 18, 1989. Kantaras adopted Forsythe's child from a prior relationship, and Forsythe gave birth to a second child through artificial insemination in 1992.

Kantaras met another woman and filed for divorce in 1998, requesting primary custody of the children. Though he won that case in 2002, it was reversed on appeal in 2004 by the Florida Second District Court of Appeal, upholding Forsythe's claim that the marriage was null and void because her ex-husband was still a woman and same-sex marriages are illegal in Florida. Review was denied by the Florida Supreme Court. The couple settled the case with joint custody in 2005.
