Britney Spears has had her life controlled by a court-ordered conservatorship since 2008.

Her father, Jamie, has overseen her personal affairs and career for much of the past 13 years, though the singer has been asking a judge to oust him from his role.

Spears, 39, is set to address a court in Los Angeles on Wednesday during a highly anticipated hearing.

Here is a timeline of events:

October 2004: Spears, one of the world’s biggest pop stars, marries backing dancer Kevin Federline.
