Two identical twin brothers have both been ordered to pay child support after refusing to say which one of them fathered a baby girl.
The Brazilian twins would allegedly trick women by impersonating each other so they could sleep with as many as possible.
But when one of the women became pregnant , neither wanted to admit he was the father.
And because both are so genetically similar, a paternity test couldn’t establish which one should pay for the child, who is today eight years old.
Court papers claim the men, identified only as Fernando and Fabricio, tried to shirk responsibility for the newborn by each blaming the other.
Judge Filipe Luís Peruca wrote: “One of the brothers, in bad faith, seeks to conceal fatherhood.
“Such behaviour, of course, should not receive a guarantee from the judiciary which, on the contrary, must repress clumsy behaviour, especially in the case in which the defendants seek to benefit from their own clumsiness.”
The judge ruled the men were denying the innocent child a right to know her biological father.
He said both brothers should be included not the girls’ birth certificate and ordered both to pay maintenance of 30 per cent of the minimum wage – 230 reals (£45) a month.
It means the girl will receive twice as much as other children from the same economic background.
The court heard that both men, from from Cachoeira Alta, in Brazil’s central Goias state, had used their resemblance to impersonate each other and notch up sexual conquests.
The judge wrote: “It is clear that the men, since adolescence, availed, deceitfully, of the fact they were identical twin siblings.
“So much so that each used the name of the other both to sleep with as many women as possible, or to hide betrayal in their relationships. It was common, then, for the brother to intentionally cause confusion by mixing up their names.”
The mother of the baby told the court she had a brief relationship with the father of her daughter, who she believed to be Fernando.
She said in her testimony she had met the man at a party of friends they had in common.
She said: “He told me he had a twin brother, but I did not get introduced.
“At the time, I did not suspect anything.”
But she said that as she learned more she later began to question the man’s identity.
She said: “The strange thing about the day is that he presented himself as Fernando, but he was with the yellow motorcycle that he said was from Fabricio”.
When she told them she was pregnant, both men claimed it was the other brother who was the father, the woman said.
Both men then underwent a DNA test, but both obtained exactly the same result – 99.9 per cent chance of being the baby’s father.
She said: “Their attitude makes me very sad, it isn’t necessary. They knew the truth, but they have used their similar appearance to flee from their responsibilities.”
Ordering both men to pay the same amount in child support, judge Peruca said: Given the peculiarities of the case, I believe the decision that most embodies the concept of justice is the one that honours the interests and rights of the child.”
He added: “And it will be detrimental to both these tortuous defendants.”
