The government-sponsored enterprises are facing another lawsuit from a county that claims the agencies owe unpaid taxes on deed recordings.

Montgomery County in southwest Ohio filed suit against Fannie Mae and Freddie Mac this week, claiming the agencies failed to make payments when filing deeds with the counties, Bloomberg-Businessweek reported.

The suit, which involves most state counties, alleges the GSEs filed exemptions to avoid paying taxes by saying they classify as government entities.

The issue of whether Fannie and Freddie are public or private corporations is a contentious one when dealing with litigation involving the mortgage giants.

Montgomery County is not the first to tackle the filing fee issue by suing Fannie and Freddie.

The Dallas County District Attorney's office made waves with a similar suit filed last year, which later pulled in additional counties.
