It was a monumental day in court as Britney's lawyer, Mat Rosengart, zeroed in on Jamie Spears, saying he committed shocking abuse and mismanagement during his tenure as conservator. Rosengart was especially outraged over recent allegations Jamie engineered a scheme to secretly record Britney in her bedroom. Rosengart says there were conversations between Britney and her kids that were captured and he called it "unfathomable."

Jamie tried arguing the conservatorship should end today, but Rosengart begged to differ. The attorney wants to hold Jamie accountable for possible misappropriation of assets, among other things, and he wants the conservatorship in place until he can investigate.

The judge agreed with Rosengart and suspended Jamie. She also ordered Jamie to turn over all the books and records during his time as conservator so Rosengart can pour through them.

Our producer asked Rosengart on the way out of court if Britney would sue her dad if there's evidence of misappropriation of assets or other misdeeds. Rosengart jumped on the question and said Britney would absolutely sue.

As for ending the conservatorship ... the judge set a hearing for November 12. It's very possible the conservatorship will be terminated on that day. Significantly, there was no talk in court about a mental evaluation as a condition to ending the conservatorship. Fact is ... all parties, including Jamie, have advocated for terminating the conservatorship without a mental evaluation, so it seems things are headed in that direction.

In the meantime, a new conservator of Britney's estate has been appointed on a temporary basis. His name is John Zabel, a CPA handpicked by Rosengart.

For Britney's part, she's over the moon, posting on social media she's on cloud 9.

We interviewed a psychiatrist, Dr. Charles Sophy, on "TMZ Live" Tuesday -- he's handled numerous court cases involving celebrities and has been involved in a number of conservatorship cases -- and he suggested the judge should terminate the conservatorship with one string attached. Britney and her doctors should come back to court in 6 months so the judge could make sure she's taking her meds. That's his suggestion, but it seems everyone is headed in the direction of just ending it.

Britney will have a safety net in fiance Sam Asghari and her current personal conservator, Jodi Montgomery. BTW, Jodi has said she will stay on even if the conservatorship ends, and Britney is agreeable.

All in all, it was a huge day for Britney, Rosengart and Co.
