The Broncos family fights against the NFL team in Denver

Two daughters of Pat Bowlen, the deceased owner of the Denver Broncos, filed a lawsuit to take control of the $ 2.5 billion team.

Beth Wallace and Amie Klemmer filed suit Friday to challenge the validity of Bowlen's confidence, reported the Associated Press. Trust is in charge of choosing the next owner controlling the Broncos.

The girls alleged that their father did not have the mental capacity when he signed his estate planning documents in 2009.

The challenge puts women at risk of being disinherited by trust because of a no-contest clause in Bowlen's will, according to the report.

Bowlen, who died in June at the age of 75, was suffering from Alzheimer's disease. Another lawsuit related to the ongoing dispute revealed that Bowlen had begun showing symptoms of Alzheimer's disease as early as 2006, the Denver Post reported.

Dan Reilly, a lawyer who represents the trust, told the AP that the lawsuit was "the last effort of their public campaign to circumvent Pat Bowlen's wishes."

Bowlen entrusted control of the team to three directors in 2014, according to a New York Times report. The directors defined the criteria that Bowlen's seven children would have to meet to become the main owner of the team, and rejected Wallace's claim that she was qualified.

Wallace had previously held a position with the Broncos, and two of Bowlen's brothers supported his bid for control, the Times reported.

But she is not alone in wanting to become the next controlling owner of the team. His younger sister Brittany Bowlen, a daughter of Pat Bowlen with his second wife, also has the ambition to take over, according to the report.

The NFL arbitration procedure is due to begin in November, the newspaper reported.
