Conduct money is the fee offered or paid to a witness in civil cases, at the time of serving summons to meet the expenses for attending court. If the fee is not paid or if he feels the amount is less , the doctor can bring this fact to the judge before giving evidence in the Court. The judge will decide the amount to be paid.
In criminal cases, no fee is paid to the witness at the time of serving summons. He must attend the court and give evidence because of interest of the state in securing justice; otherwise, he will be charged with contempt of court. However, in criminal cases, conveyance charges and daily allowance can be claimed by the doctor according to Government rules.
