Allen Iverson's wife is once again calling off her marriage to the ex-NBA star ... filing divorce papers in Georgia for the second time in 15 months.
Tawanna Iverson filed legal docs in Fulton County on Monday -- saying her 10-year marriage is "irretrievably broken."
According to the docs, the two have 5 minor children together ... and Tawanna wants sole legal and physical custody.
Tawanna is demanding child support and alimony payments -- she's also gunning for her fair share of the property and money accumulated during the marriage.
Just last year, Tawanna filed for divorce from Allen -- but dropped it.
As for Allen, he's currently playing pro ball in Turkey.
