Helgenberger cited irreconcilable differences as the reason behind her split from actor Alan Rosenberg, and is seeking spousal support while asking the court to deny him any.
"After 19 years of marriage, Marg and Alan have decided to take some time apart," the actress's rep told PEOPLE last October. "They love and respect each other and remain committed to their family."
Helgenberger, 50, and Rosenberg, 58, have an adult son together.
