A man who pretended to be a forensic psychologist took a father to court for refusing to pay more than £16,000 for an inquiry into his son's death.
Mr Morrison worked as an expert forensic psychologist in court cases
Gene Morrison, 48, of Martin Street in Hyde, Cheshire, only had qualifications bought from the internet, Manchester Minshull Street Crown Court heard.
Barry Power, of Liverpool, told the court he refused to pay after receiving "little information" in return.
Mr Morrison admits perjury but denies lying about his qualifications.
He is charged with nine counts of obtaining money by deception, three counts of attempting to obtain property by deception, eight counts of perverting the course of justice and three counts of perjury - lying on oath - between 2002 and 2005.
He has pleaded guilty to a single count of attempting to pervert the course of justice and one count of perjury, but denies the other charges.
The court was told that Mr Morrison was hired by Barry Power after his son, Barry Power jnr, was found dead by his brother in his bedroom and a post-mortem failed to reveal the cause of death.
The prosecution allege Mr Morrison outsourced work to qualified experts, but led Mr Power to believe his company was conducting the investigation itself.
When Mr Power did not pay him, he launched civil proceedings claiming over £16,000.
Prosecutor Neil Flewitt QC told the court Mr Morrison had also been involved in investigations into rape, death by dangerous driving, drug possession and drug-impaired driving.
He gave evidence in court on subjects he had no training on and produced "sham" reports for the courts "cut and pasted from the internet and then packaged up as if they were based on his own expertise", Mr Flewitt said.
The trial continues.
