Lindsay Lohan -- Everyone's On Board to End Formal Probation

Lindsay Lohan is in the clear ... if she doesn't screw up in the next 48 hours, she will be off formal probation for the first time in more than 4 years ... TMZ has learned.

Sources tell us ... The L.A. County District Attorney is satisfied Lindsay completed the terms of her probation. As a result, the D.A. will accept the L.A. County Probation Department's report that Lindsay has complied with all the terms of her probation. We've learned the D.A. will have no objection to Judge Stephanie Sautner terminating Lindsay's probation in the Beverly Hills DUI case.

As for Lindsay's other little problem -- the jewelry heist -- we've learned the L.A. City Attorney sees no reason why Lindsay's formal probation -- requiring her to regularly report to her probation officer and the judge -- will be changed to informal probation, meaning as long as Lindsay keeps her nose clean she is off the hook for misdemeanor theft.
