Wade Robson -- I Don't Need to Sue Michael Jackson Estate to Prove Molestation

Wade Robson WILL have his day in court in his attempt to prove he was molested by Michael Jackson ... even if he's shut down by the Michael Jackson Estate.

TMZ has learned ... Robson has filed a civil lawsuit in L.A. County Superior Court ... and it has nothing to do with his creditor's claim against the Estate. We broke the story ... Robson belatedly filed his creditor's claim, alleging MJ molested him between the ages of 7 and 14.

Robson may get shut down by the probate judge because he waited too long to file his claim. But the civil lawsuit we found will NOT go away that easily.

The allegations in the civil lawsuit are sealed, but TMZ has obtained the face page of the complaint, which shows Robson is suing DOE 1, an individual, DOE 2, a California corporation, and DOE 3, a California corporation. As for who these anonymous DOES are ... TMZ has done some digging, and it's clear. Robson is targeting MJJ Productions -- Michael's record label (owned by Sony) which hired Wade when he was 11 -- and MJJ Ventures ... which produced Michael's music videos.

The two corporations may have been involved in bringing Wade to the U.S. from his home in Australia, and it's clear Wade will argue they had some responsibility for protecting him -- kind of like the relationship between priests who molest and the Catholic Church.

As for the individual DOES (Wade names 50 DOES) ... it's very clear from our research that Robson is targeting the two executors of the MJ Estate -- John Branca and John McClain.

Short story -- even if Wade loses in probate court, he can probably have his day in civil court and put Michael Jackson and allegations of molestation before a jury.
