Robin Williams' wife files for divorce

Robin Williams' wife has filed for divorce after 19 years of marriage, the actor's rep has confirmed.

According to the San Francisco Chronicle, Marsha Garces Williams filed a divorce petition in San Francisco on March 21, citing irreconcilable differences. The pair have two children together: daughter Zelda, 18, and son Cody, 16.

The couple married in April 1989, shortly after Robin's divorce from his previous wife.

According to the eight-page court filing, Garces, 51, is asking for joint legal custody of Cody – that the boy live with her and Williams get visitation – as well as payment of attorney fees and spousal support (amount to be determined).

The papers indicate she will ask the court to divide their property once all their assets have been tallied.

Williams, 56, has served two stints in rehab; one for drugs in the 1980s; and another for alcohol in 2006.
