Allen Iverson's Wife Wants Restraining Order

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.
