A judge in Brazil has reportedly ordered for Ronaldinho's passport to be seized, with the former Barcelona star having unpaid debts of £1.75 million (NZ$3.4m).
According to reports in Spain, authorities found a total of just £5.24 (NZ$10.28) in Ronaldinho's bank accounts.
As reported by Spanish newspaper Marca, Ronaldinho and his brother Roberto Assis were fined for illegal construction in a protected area.
Despite reportedly mortgaging their property, it is said they haven't been able to pay off the debt because of high interest.
Ronaldinho has spent time in China and Japan for advertising reasons in recent weeks. The 38-year-old officially retired from playing earlier this year following a lengthy career.
Best known for his time at Barcelona, with whom he won the Champions League and two La Liga titles, Ronaldinho also won the World Cup in 2002.
Ronaldinho is scheduled to take part in The Game of Champions friendly in Frankfurt on November 17.
