A judge approved Wilde’s split from documentary filmmaker Tao Ruspoli on September 29 in Los Angeles.
The judgment does not indicate how the former couple will divide their assets.
Wilde filed for divorce in March, two months after she and Ruspoli separated.
The pair have no children together.
The House star cited irreconcilable differences in her divorce petition. Wilde starred in Tron: Legacy and Cowboys & Aliens.
Ruspoli is the son of an Italian prince.
