Allen Iverson’s ex-wife is sick and tired of dragging him to court to squeeze out child support … she’s asking a judge to make him cough up the next 13 years worth RIGHT NOW — a cool $1.2 MILLION.

TMZ broke the story … after the couple’s nasty divorce Iverson was ordered to pay $8000/month in child support for their 5 kids. Problem is, Tawanna has gone to court on numerous occasions because A.I. won’t pay.

It came to a head in July when a judge threatened Iverson with jail, unless he forked over $40,000 in back support — which he did. But Tawanna says she doesn’t want to keep running into the same problem.
