Walsh, who played Dr. Sean McNamara opposite Julian McMahon as Dr. Christian Troy on the FX plastic-surgery drama, has been married to Going since October 2004. According to the filing, he expects to be paying spousal support and wants joint legal and physical custody of daughter Stella, TMZ says.
Walsh also has two children with his first wife, actress Melora Walters.
