Britney Spears’ New Would-Be Attorney to Plead His Case to Represent Her

Britney Spears is hoping it’s “out with the old and in with the new” in her conservatorship — a new hearing in the case is going down, and her new hand-picked attorney will have the spotlight.

The judge in Brit’s conservatorship will hear arguments Wednesday in downtown L.A. on several issues — the most important one to Britney — is who will be her attorney going forward.

Like we first told you … Britney’s longtime lawyer, Sam Ingham, filed paperwork seeking to get out of the case, and she’s already decided she wants former federal prosecutor Mathew Rosengart to be her new attorney.

TMZ broke the story … Britney wants to hire Rosengart, of Greenberg Traurig, LLP, and he’s expected to make an appearance before the judge to make his pitch for getting the job. We’re told he’ll argue she has a right to choose her own attorney on her own accord, without her father, Jamie, getting in the way as conservator of her estate.

Keep in mind, Jamie’s probably a bit conflicted because Rosengart will likely seek to remove Jamie as conservator of Britney’s estate.

We’re told his plan is to explain how Britney has a constitutional right to Due Process … which includes being able to select counsel of her choice. That certainly exists in a criminal case, and it’s likely Rosengart will argue that the conservatorship is similar to a criminal case because it deprives Britney of her personal liberty.

Remember … the last hearing had all kinds of fireworks … as Britney testified before the judge — accusing her family of using her and controlling her life via the conservatorship, including allegedly forcing her to tour.

She claims she hasn’t been able to get married or have any further kids — which she apparently wants with Sam Asghari — and made it clear … she wants to be done with the conservatorship..

We’re monitoring the proceedings as they go on, plus the commotion outside — as there are #FreeBritney protestors who’ve gathered, like they have done for months now. There are also protestors gathered in D.C.
