According to court documents obtained by RadarOnline.com, Arnold filed on Wednesday in Los Angeles, asking for “Dissolution w/ Minor Children.”
Arnold and Groussman have two children, Quinn and Jax, and four dogs together.
Arnold is reportedly requesting joint custody, according to The Blast, and the two are currently trying to come to a mutual agreement on all the financial details.
The couple tied the knot over Thanksgiving 2009 in Maui in front of 75 guests. Fellow comedian Dax Shepard served as best man.
This marks Arnold’s fourth failed marriage. He was married to Roseanne Barr from 1990 but divorced in 1994.
