On May 16, 2008, Takei announced that he and Brad Altman would be getting married. They were the first same-sex couple to apply for a marriage license in West Hollywood. On June 17, shortly after Takei and Altman obtained their marriage license, they spread the news by holding a press conference outside the West Hollywood city auditorium. They were married on September 14, 2008, at the Democracy Forum of the Japanese American National Museum in Los Angeles, of which Takei is one of the founders.Walter Koenig was his best man, and Nichelle Nichols was the matron of honor. Reverend William Briones of the Nishi Hongwanji Buddhist Temple of Los Angeles presided.
Takei's marriage is one of thousands of same-sex marriages that took place at a time when same-sex marriage was legal in California. The California Supreme Court ruled that Proposition 8, which banned same-sex marriage in California, did not affect Takei's marriage and other same-sex marriages entered into before its passing on November 4, 2008.
