Britney Spears' coconservator has asked for increased security after receiving a deluge of threats

• Jodi Montgomery has been Britney Spears' conservator alongside Spears' father since 2019.
• She's asking Spears' estate to cover her security, which is estimated to cost $1,820 a day.
• Montgomery's attorney said her client had received a "marked increase" in threatening messages.

Britney Spears' coconservator Jodi Montgomery has asked for increased security in a new court filing cited by NBC News and Fox News, citing an increase in threats of death and violence sent to her.

Montgomery, who has served as a temporary conservator of the singer's estate alongside Spears' father, Jamie, since 2019, said there had been a "marked increase in the number and severity of threatening posts" sent to her over social media, text, phone, and email since Spears' bombshell testimony on June 23 pleading for an end to her conservatorship.

In the court documents, which were filed Wednesday, Montgomery's attorney said the coconservator had been recommended 24/7 physical security until she could make "certain security improvements at her home office/residence," according to NBC News and Fox News.

According to NBC News, the filing said each security agent assigned to Montgomery cost $65 an hour, with an estimated cost of $1,820 per 24-hour window. A two-week security detail would cost about $25,480.

Citing the prohibitive costs, Montgomery asked for Spears' estate to cover the expenses, which would require approval from Jamie Spears and a judge, the outlets reported.

Representatives for the elder Spears did not immediately respond to a request for comment from Insider.

Montgomery is one of the last coconservators standing

In Spears' June 23 testimony, the singer asked a judge to end the "abusive" 13-year conservatorship that controls her finances and professional decisions, saying she was forced to work long hours and was denied permission to remove her birth-control device despite wanting more children.

In response, Jamie Spears said in court documents filed on June 29 - and reviewed by Insider - that he stopped making decisions related to his daughter's "personal affairs" after Montgomery signed on as a temporary conservator in September 2019.

When reached by Insider on June 30, a representative for Montgomery countered the elder Spears' claims and said over email that Montgomery had been a "tireless advocate" for Spears as the pop star's coconservator.

On Tuesday, Montgomery's lawyer said in a statement provided to Insider that she had no plans to step down as the pop star's conservator - and said Spears asked her to remain in her guardianship role.

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

Sam Ingham, a lawyer who has represented Spears for more than a decade in her conservatorship, filed court documents Tuesday requesting to resign from the case.

Spears' longtime manager Larry Rudolph also resigned Monday, saying Spears wanted to retire from performing.

Before Rudolph resigned, Judge Brenda Penny had approved Bessemer Trust's request to be removed as a coconservator, citing Spears' explosive testimony asking to end her conservatorship. That same week, however, the judge formally denied Spears' request to remove her father from the guardianship.
