Lindsay Lohan vows ... she will NEVER again step foot in front of another judge.
Lindsay was on break at the L.A. County morgue Wednesday -- where she officially completed her community service obligation -- when she vowed to stay clear of all courtrooms for the rest of her life.
As for her big post-probation celebration tonight -- Lindsay said she plans to grab dinner with her sister, and that's about it.
Lindsay also says she doesn't plan to see her intrepid lawyer Shawn Holley very often after today's hearing -- but adds, Shawn "is still a good person in my life. She's been there for me."
Understatement of the century.
