Meg Irsay filed a divorce petition in Hamilton County Superior Court in Noblesville on Thursday citing an ''irretrievable breakdown'' of the marriage. She is asking the court to divide their marital estate.
A joint statement issued by the couple said Jim Irsay will retain full ownership of the Colts and his other business interests.
The couple married Aug. 2, 1980. They have been separated for a decade.
Jim Irsay has owned the Colts since 1997 following the death of his father, Robert Irsay.
