The couple have been remanded in custody as the prosecution fear they may return to India to evade trial, a statement from Oslo police said. The verdict is expected on Monday.
Police arrested Chandrasekhar after his son complained to school teachers that his parents had threatened to send him back to India.
The child was reprimanded for wetting his pants in the school bus, according to Chandrasekhar's nephew V Sailender, who is in Hyderabad.
The incident comes barely months after another row involving an Indian couple and their children in Norway. At that time, the Indian authorities had taken up the matter strongly.
But this time, there is little that the government can do, since the incident involves two adults in a legal process for violation of law. India has sought consular access and officials from the Indian mission met Chandrasekhar to ensure things are smooth, sources said. (With agency inputs)
