The six-time Grand Slam winner said the negative publicity had damaged “brand Becker” and left him struggling to make enough money to pay off his debts.
The 54-year-old German said he had been seeking to pay off a more than £3 million loan from private bank Arbuthnot Latham, including through the sale of his estate in Spain.
The court heard the bankruptcy decision came days before Wimbledon, where Becker was working for the BBC as well as Australian and Japanese television stations.
“As you can imagine, I was very shocked at the fact. Because it was all over world news, and I walked through the gate of Wimbledon and everyone knew. I was embarrassed because I was bankrupt,” Becker said.
He told jurors the bankruptcy was also in the midst of a “stressful time” with his then wife Sharlely “Lilly” Becker, while they were living in “separate quarters” at his rented house in Wimbledon.
Describing an incident while he was commentating on the men’s quarter-final involving Roger Federer, he said: “My son called me saying my wife was breaking down the house – the furniture, the windows. The police came… while I was on site.”
Boris Becker, who arrived at court with his partner Lilian de Carvalho Monteiro, sat at the witness box on Monday to give evidence.
“It is very difficult when you are bankrupt and in the headlines every week for it. It is very difficult to make a lot of money with my name,” he said.
Boris Becker has denied all charges
The former world number one, who was occasionally helped to give evidence by a German translator, denies 24 charges under the Insolvency Act.
He is accused of failing to hand over nine trophies, including two of his three Wimbledon men’s singles titles, an Olympic gold medal, his 1991 and 1996 Australian Open trophies and his Davis Cup trophy and gold coin.
