A year after undergoing a sex change, Chaz Bono is now legally a man.
A Santa Monica, Calif., judge granted the political and social activist’s petition for a gender and name change Thursday, according to a spokesperson for the Transgender Law Center, which represented Bono.
“Chaz couldn’t be happier,” says Kristina Wertz, legal director for the Transgender Law Center. “This is an important step in his transition and will allow him to change a variety of his identity documents to show who he truly is.”
