Pop star Britney Spears on Friday regained control of her personal life and her money when a judge ended a 13-year conservatorship that became a cause celebre for fans and critics of an arrangement typically meant to protect the elderly.

“Effective today, the conservatorship of the person and the estate of Britney Jean Spears is hereby terminated,” Los Angeles Superior Court judge Brenda Penny said after a 30-minute hearing in which no one opposed ending the court-sanctioned arrangement.

The 39-year-old Piece of Me singer had begged the court for months to terminate the conservatorship that has governed her personal life and $60 million estate since 2008.

Spears did not attend Friday’s hearing but said in an Instagram post, “I love my fans so much it’s crazy!!! I think I’m gonna cry the rest of the day !!!! Best day ever.”

Outside the courthouse, dozens of fans erupted into cheers and tossed pink confetti into the air when they heard the news. Some danced and sang to her hit Stronger.

“It was a monumental day for Britney Spears,” the pop star’s attorney, Mathew Rosengart, said outside the courthouse. He thanked the #FreeBritney movement which he said had been essential to ending the legal arrangement. The conservatorship was set up and overseen by the singer’s father, Jamie Spears, after she had a public breakdown in 2007 and was hospitalised for undisclosed mental health issues.

Interest in the case was propelled in the past year by documentaries and the #FreeBritney movement of fans who questioned why the singer needed such restrictions while she was touring around the world and earning millions of dollars.

Lauriann Wright, the attorney for Jodi Montgomery, who had been entrusted with overseeing Spears’s personal life, told the judge there was “no reason this termination cannot happen and Ms. Spears cannot live a safe, happy and fulfilling life”.
