Tawanna Iverson just filed legal docs in the couple’s bitter divorce battle — claiming Allen “has engaged in increasingly contemptuous, threatening, and disturbing behavior” over the last few months … and she’s afraid things will get worse.

Tawanna is asking for a judge to issue a protective order stat. It’s unclear whether she wants Iverson to stay away physically, or just stop harassing her.

Tawanna also claims Allen is hiding big money from her — and she wants a judge to stop him.

Calls to Allen’s camp were not returned.
