The 39-year-old pop princess' new attorney Matt Rosengardt just filed documents requesting the court dumps Jamie and appoints Jason Rubin as the conservator of Spears' estate.
Rubin is a CPA who, at least up until now, does not appear to have any ties to the singer.
He does have a long list of credentials, which Rosengardt believes makes him more than capable of handling Spears' business affairs and multimillion estate.
According to the documents, Spears' lawyer is asking for Rubin to have full access to her estate. He also wants the CPA to be granted power of attorney to make health care decisions for the singer.
The documents reveal the Grammy winner's net worth is just shy of $69 million.
Jodi Montgomery is currently the person with power of attorney over Spears' health care decisions, which means the singer might be trying to oust her as well as Jamie.
Spears' net worth is broken down like this -- her cash assets are listed at $2,730,454.
When it comes to her non-cash, the star is rolling in the dough at $57,666,398.
Spears' real estate properties are listed at $8,455,483, and that's not including everything.
The bold move to replace her father as her conservator comes just weeks after getting rid of her court-appointed attorney and replacing him with Rosengardt.
Spears took the stand virtually on June 23, giving an emotional testimony when addressing the judge in her 13-year conservatorship for the first time.
She claimed Jamie had too much control over her life -- including her future with boyfriend Sam Asghari.
Spears spewed a number of allegations against her father.
The singer said she wanted more children but claimed her conservator refused to allow her to remove her IUD.
Spears made it crystal clear for the court about what she's hoping to gain by speaking out.
“The main reason why I’m here is because I want to end the conservatorship without having to be evaluated. I’ve done a lot of research, ma’am. And there’s a lot of judges who do end conservatorships for people without them having to be evaluated all the time. The only times they don’t is if a concerned family member says something’s wrong with this person," she told the judge.
