Tennis legend Chris Evert has filed for divorce from former Olympic skier and award-winning sport fisherman Andy Mill, her husband of 18 years, in a Broward County, Fla., court, PEOPLE has learned.
Evert, 51, filed her complaint Nov. 13 in Fort Lauderdale, a county south of the couple’s $2.5 million home in Boca Raton, Fla., where Evert resides with their three sons, ages 15, 12 and 10.
According to Evert’s petition, “The marriage between the parties is irretrievably broken.”
The pair announced their split last month, calling the decision “mutual.” “Our main concern is for our three sons. We know we have some difficult times ahead, together and apart, and hope that our family’s privacy will be respected.”
The marriage was the second for both – Evert was divorced from English tennis star John Lloyd in 1987 after an eight-year marriage.
