Katherine Jackson to Joe: Don't Drag Me Into This!

Joe Jackson has no business dragging his wife into the wrongful death lawsuit he's filing against Dr. Conrad Murray ... this according to her lawyer.

TMZ broke the story ... Brian Oxman is filing the wrongful death suit in federal court today.  Oxman has named Katherine and Michael Jackson's three kids as "nominal plaintiff."

It's bizarre to name anyone as a "nominal plaintiff" in such a case.   As far as we can tell  -- plaintiffs in wrongful death cases never bring in others as "nominal plaintiffs."

That said, Katherine's lawyer, Adam Streisand, tells TMZ, "Mrs. Jackson has no interest in Conrad Murray other than seeing that justice is done in the criminal courts." 

Streisand adds, "She certainly would never tap Brian Oxman for the job of filing any kind of lawsuit for her or the kids."
