According to court documents, obtained by TMZ, Shumpert says Teyana never proved he made her feel endangered, despite making the claim in recently filed divorce papers. Iman wants the court to take action, and to remove Teyana's accusations from the documents.

To get specific, Teyana put something called "cruel treatment" as grounds for the couple's divorce, which is defined as "willful infliction of pain bodily or mental ... [that] reasonably justifies apprehension of danger to life, limb, or health."

Iman says that's nonsense, and the only grounds should be "irretrievable broken bond." He wants the "cruel treatment" grounds thrown out.

What's more, Iman says despite Teyana's claims, he's never been irresponsible when it comes to the care of their two daughters, seven-year-old “Junie” Tayla, and three-year-old Rue Rose.

The new filing from Iman is just another chapter in what's already become a nasty custody battle. As we reported, Teyana first filed the divorce docs using only the couple's initials in an attempt to keep everything private from the public.

However, Iman blew the lid off the secret when he filed a motion asking the court to attach their full names to the documents ... and allowing the public to know what was going on.
