In the London criminal trial against Boris Becker, the jury found the former German tennis star guilty on several counts.
The jury decided on Friday that the 54-year-old withheld parts of his assets from his insolvency administrator Mark Ford.
Theoretically, Becker could face a prison sentence.
The sentence is to be announced on April 29th.
Becker followed the verdict with a red head.
He can still appeal the verdict.
Becker was declared bankrupt on June 21, 2017.
The jury has now concluded that he failed to disclose all of his possessions on 4 of 24 counts, contrary to legal requirements.
The allegations involved bank accounts and real estate, as well as several trophies, including the Wimbledon trophy from Becker's first win at the all-important Grand Slam tournament in 1985.
In the defense, Becker's lawyer Jonathan Laidlaw drew the picture of a man who has led an extraordinary life since his first Wimbledon victory at the age of 17 and is overwhelmed in financial terms.
"This man is hopeless with money," he said.
Becker was too trusting and dependent on his advisors.
He denied intentional deception and the accusation that he had "led the authorities by the nose".
Prosecutor Rebecca Chalkley did not believe his statements.
Becker intentionally transferred money to other accounts in order to prevent his insolvency administrators from accessing it.
He also knew that he was registered as the owner of several properties, she said in the process.
Becker had repeatedly come into contact with the judiciary since the end of his career in 1999.
In 2002 he was sentenced to probation and a fine in Munich for tax evasion.
