Culture Minister Mahesh Sharma told the parliament that government had not found any evidence to support the claim.
The lawyers had filed a petition in a court last year saying that the monument should be handed over to Hindus.
Sharma said government is aware of the suit. On a specific query about the evidence of it being Hindu, minister replied in the negative. He also said that so far government has not observed any affect on tourism because of the controversy.
The Taj Mahal, a 17th Century mausoleum built by Mughal emperor Shah Jahan, a Muslim, after his wife’s death, attracts about 12,000 visitors a day.
Six lawyers belonging to the city of Agra, where the monument is located, had told a court there was substantial evidence to prove that the famous monument was originally a temple dedicated to the Hindu god Shiva.
They had urged the court to declare the monument a Hindu temple.
