The Ivorian was released by manager Hossam Hassan in the summer, with Zamalek owing him $65,000 from his old contract.
"Zamalek owe Adiko $65,000. We made several requests to the board but to no avail," Adiko's agent Rami Saad told FilGoal.com.
"The club have until September the 25th to pay the dues. After that date we will take legal action."
Adiko, who struggled to play regularly under Hassan last term, is currently with Libyan outfit Al-Akhdar.
