Amanda Bynes is less than 24 hours from personal freedom — a judge just set the stage for the end of her conservatorship.

According to new legal docs obtained by TMZ, the judge for the case issued a tentative ruling Monday saying Amanda’s conservatorship is “no longer required.”

While it’s a tentative ruling, there is a court hearing scheduled for Tuesday morning and it’s almost a certainty the judge will make it official … because no one is objecting to Amanda’s petition to end her conservatorship.

Remember … the former child star was placed under a conservatorship back in 2013, following a string of bizarre episodes brought on by what she has said is bipolar disorder. Amanda says she’s been sober for several years now, thanks in part to getting support through AA.

She filed the docs last month to end the 9-year conservatorship, a move her father and mother — who is Amanda’s conservator — fully support.
