Iggy Azalea took her ex to a medical clinic when they were still together and told the doctor he was her husband -- so claims the doctor -- and now the ex is using that representation to get at her fortune.
Hefe Wine -- aka Maurice Williams -- filed a declaration from a doctor in their "divorce" in which the doc says in 2008 he saw Iggy and Hefe in his clinic and says they left an impression on him because "she was a white Australian female and he was a taller black man."
The doctor also says Iggy introduced Hefe as her husband.
It's significant because Iggy and Hefe were together from 2008 until last year, and under Texas law a man and a woman who live together for any length of time are considered legally married if they agree to be married and hold themselves out as husband and wife.
The consequences are significant ... Hefe wants a piece -- presumably half -- of all of the songs she wrote while they were together. While they are still fighting in court, Hefe isn't allowed to release any of her old music.
