Los Angeles, California – Britney Spears' court-appointed lawyer has offered his resignation as the fallout from the pop superstar's dramatic testimony continues.

Samuel Ingham, who had represented the singer since she was placed under a conservatorship in 2008, announced his desire to step down on July 6.

A court filing in Los Angeles obtained by the PA news agency states: "Samuel D. Ingham III hereby resigns as court-appointed counsel for Britney Jean Spears, conservatee, effective upon the appointment of new court-appointed counsel."

Loeb & Loeb, a law firm brought in to help Ingham, also offered its resignation in the filing.

On June 23 she told Judge Brenda Penny she was unaware of how to terminate the conservatorship and suggested she wanted to hire her own lawyer.

The court appointed Ingham after Spears (39) was deemed incapable of finding her own legal representation following a series of mental breakdowns.

According to the most recent accounting available, in 2019 Ingham was paid about $373,000 for working with the singer.

Spears pays the legal costs of those on both sides of the case.

Ingham's resignation will take effect as soon as Spears has new representation, the filing states.

The conservatorship – an arrangement usually reserved for the very old and infirm – is overseen by Spears's father, Jamie, and her care-giver, Jodi Montgomery.

Jamie Spears is in control of his daughter's estate, estimated to be worth more than $50 million, while Montgomery oversees Spears's personal affairs on what remains a temporary basis.

The financial management firm appointed by the court as co-conservator of the estate – Bessemer Trust – asked to be withdrawn from the role last week, citing the singer's demand for the conservatorship to be terminated.

Spears's long-time manager, Larry Rudolph, quit this week and said he had been told the chart-topping star planned to "officially retire."

However, Montgomery has no plans to step down, according to her lawyer.

In a statement obtained by PA, Lauriann Wright said: "Ms. Montgomery has no plans to step down as Ms Spears's Temporary Conservator of the Person.

"She remains committed to steadfastly supporting Ms. Spears in every way she can within the scope of her duties as a conservator of the person.

"Ms. Spears as recently as yesterday has asked Ms Montgomery to continue to serve. Ms. Montgomery will continue to serve as a conservator for as long as Ms. Spears and the Court desire her to do so."

Spears has not performed since 2018 and previously told the court she has no plans to do so while her father maintains control over her career.

Lawyers for Jamie Spears, who has been widely criticized for his role in the conservatorship by those in the #FreeBritney movement, say his canny management of the estate saved his daughter from financial ruin.
