Robin Williams and his wife Marsha Garces Williams are to divorce after 19 years of marriage.

Reuters reports that Garces Williams filed for divorce in a San Francisco court last week, citing irreconcilable differences.

Williams and his wife have been separated since 31 December.

Garces Williams is requesting joint custody of their 16-year-old son; they also have an 18-year-old daughter.

The actor met his second wife when she worked as a nanny, taking care of Williams' son with his first wife.
