Cariani said the money was owed to the Monte dei Paschi di Siena bank.
Some Italian media outlets said that Pavarotti had spent large sums on trips to the U.S., where he had been undergoing expensive medical treatment.
However, the singer's relatives reportedly inherited 20 million euros in shares, including 10 million euros meant for his second wife Nicoletta Mantovanni, with the remainder to be spilt between Nicoletta and the singer's four daughters.
Newspapers allege the sums will barely be enough to cover all of his debts.
However, it is hard to say whether or not the media allegations are true, as almost all rumors about the legendary opera singer have been denied by his relatives.
Pavarotti died on September 6 at his villa in Modena at the age of 71, after battling cancer for over a year.
