The Crown Prosecution Service spent £87,908 on QCs and £48,612 on junior counsel for the extradition process.
Officials spent £23,464 on psychiatric reports after the Bristol businessman, 35, was accused of plotting bride Anni’s murder, a Freedom of Information request showed.
The CPS said its solicitors spent 496 hours on the case. Previous figures show they are paid about £69 an hour so their fees add £34,000 to the overall cost.
Police, transport, medical and other costs are likely to push the total bill to a quarter of a million pounds.
The Home Office and Scotland Yard also racked up costs.
The care home boss fought a three-and-a-half-year battle against extradition after Anni, 28, died in Cape Town in 2010.
Judge Jeanette Traverso ended his trial there before he was even called to the stand to give evidence.
None of the money is recoverable from the South African authorities, the Home Office confirmed last week.
Anni’s family has vowed to launch a civil case against Dewani, who revealed he was bisexual at his trial.
