Britney Spears Wants Conservatorship Case Open to Public, Supports #FreeBritney

Britney Spears is making it clear -- she doesn't trust her dad and wants the public to hear what he and other professionals are doing to keep her in the conservatorship, and she also says the #FreeBritney movement's not only real ... she supports it.

Britney's lawyers just filed docs opposing her dad Jamie's motions to seal parts of her ongoing conservatorship case ... because she wants everyone to know what's up.

Britney is fighting her dad's move to appoint a co-conservator of her estate [handling business matters] to a lawyer who was deeply involved in her conservatorship for years. She wants someone independent to take the reins.

Britney argues there are no medical issues or sensitive issues with her children to protect, so there's no reason to keep the hearing secret.

The lawyer says, "... Britney herself is vehemently opposed to this effort by her father to keep her legal struggle hidden away in the closet as a family secret."

The lawyer adds, "Far from being a conspiracy theory or a 'joke' as James [Jamie] reportedly told the media, in large part this scrutiny is a reasonable and even predictable result of James' aggressive use of the sealing procedure over the years to minimize the amount of meaningful information made available to the public."
