The actress, who currently stars in the FOX series "Alcatraz", filed papers in Los Angeles Super Court, citing "irreconcilable differences".
The couple began dating in 2002 and married seven years later in two ceremonies: one civil and one traditional Sikh ceremony. They have a two-year-old son, Kai David Singh.
The 36-year-old British actress of Indian descent has appealed that she be awarded primary physical custody of their son and that Stenson be granted visitation rights. She has also asked the court to deny Stenson any spousal support, reports usmagazine.com.
