Jamie Spears has agreed to step down from his long time role as conservator of his daughter Britney Spears’ estate “when the time is right,” according to court filings.

Jamie Spears’ departure would mark a significant development in the singer’s long fight to be freed from her father’s control.

In a court filing on Thursday, a lawyer for Jamie Spears wrote that he “does not believe that a public battle with his daughter over his continuing service as her conservator would be in her best interests”, adding, “Mr Spears intends to work with the court and his daughter’s new attorney to prepare for an orderly transition to a new conservator.” The filing said that Jamie had “already been working on such a transition” with his daughter’s previous lawyer.

The filing continued, “Mr Spears continues to serve dutifully, and he should not be suspended or removed, and certainly not based on false allegations. Mr Spears is willing to step down when the time is right, but the transition needs to be orderly and include a resolution of matters pending before the court.”

A lawyer for the pop singer told multiple media outlets on Thursday that Jamie Spears had agreed to step down as conservator. “We are pleased that Mr Spears and his lawyer have today conceded in a filing that he must be removed,” her attorney, Mathew Rosengart, said in a statement to CBS News. “It is vindication for Britney. We are disappointed, however, by their ongoing shameful and reprehensible attacks on Ms Spears and others.”

The developments come nearly two months after the singer spoke in court and called for an end to the controversial arrangement that has controlled her life for 13 years, giving her father and others authority over her personal life and career.

She has repeatedly accused her father of “conservatorship abuse” and said the conservatorship forced her to work against her will and controlled personal health decisions and whether she could marry or have another child.

The filing from Jamie Spears’ attorney on Thursday said he had been subject to “unjustified attacks” and false allegations.

This is a developing story.
