Britney Spears’ father Jamie has petitioned a Los Angeles court to end the pop singer’s 13-year conservatorship, NBC News and CNN report.

Britney had told the court in June that the arrangement was abusive and humiliating.

She had filed legal documents asking that her father be immediately removed as the overseer of her $US60 million ($A81 million) estate.

In a court filing in August, Jamie Spears said he was willing to step down from the role.

In a new document on Tuesday (US time), he went a step further and asked the court to end the conservatorship entirely, according to NBC News and CNN.

Britney “is entitled to have this court now seriously consider whether this conservatorship is no longer required”, Jamie Spears said in a filing cited by the media outlets.

Her circumstances had changed “to such an extent that grounds for establishment of a conservatorship may no longer exisr”, he said.

Representatives for Mr Spears did not immediately respond to a request for comment.

Britney, 39, remains under the care of professional Jodi Montgomery, who manages her medical and personal affairs.

The nature of the singer’s mental health issues have never been publicly revealed.

She has received support from the FreeBritney fan campaign that has rallied for her release form the legal arrangement.

Los Angeles Superior Court Judge Brenda Penny scheduled the next hearing in the case for September 29.
