The Hollywood actor, 68, and model and handbag designer Christine Baumgartner, 49, announced in May they were parting ways after nearly 19 years of marriage.
Having dated for four years, the couple got married at his Colorado ranch in 2004.
They have a 12-year-old daughter and two 14- and 15-year-old sons.
According to a statement from the publicist for the Bodyguard star, “it is with great sadness that circumstances beyond his control have transpired which have resulted in Mr. Costner having to participate in a dissolution of marriage.”
