Beşiktaş were paid a visit by debt collectors at their Istanbul offices to retrieve money owed to advertising company Aktif Tanıtım Şirketi according to DHA.
Possessions belonging to the football club were confiscated as a result of legal proceedings launched by the advertising agency over unpaid debts.
Beşiktaş reportedly had an $8.8 million debt with the company from the Yıldırım Demirören era.
Former Beşiktaş president Demirören left the club in debt trouble before taking over as Turkish Football Federation (TFF) president.
Demirören was in charge between 2004 to 2012 and signed a number of high profile players including Ricardo Quaresma, former Real Madrid Captain Guti, Simao Sabrosa, Hugo Almeida, Roberto Hilbert and Matteo Ferrari among scores of others.
The debt was later reduced to $3.8 million and an agreement was reached to pay it in instalments by current club president Fikret Orman.
The advertising company has however, complained that Beşiktaş have failed to pay the instalments on time.
Beşiktaş officials appealed against the confiscation, calling the move unethical.
The Black Eagles could be in further trouble as former players Allan McGregor, Manuel Fernandes and Sezer Öztürk are reported to have started legal proceedings over €400,000 owed to them by the club from the Demirören.
