However, Tina Ambani, like her husband, played safe with all Central Bureau of Investigation (CBI) questions and said she is not actively involved with Anil Ambani's business affairs.
"I am a social worker. I look after my family and keep engaged in social work. I am not actively involved in the business and the company's affairs," she said.
"Before a meeting, they brief me, I am told what to do. I follow instructions. If something has been recorded, it must be true. This meeting was in (January) 2006. It is difficult for me to recall now in 2013," she said.
The CBI claimed Tina Ambani is hiding facts and sought the court's permission to re-examine her.
"Tina Ambani is deliberately concealing facts. Her replies are not satisfactory. We want to cross examine her. It was she who gave herconsent to the documents. She is denying the role played by her," the CBI said.
Anil Ambani on Thursday appeared as a prosecution witness in the 2G case at the court even as the CBI probing the scam declared him a hostile witness.
The billionaire industrialist of one of the foremost business family of India said he cannot recall any details related to the case.
"I don't remember," was all Anil Ambani said to most CBI questions in the case where three of his Reliance Telecom employees have been charged over payments to Swan Telecom.
Anil Ambani, however, informed the court that his wife Tina Ambani will also appear as a witness on Friday.
Anil Ambani appeared as a CBI witness in the scam case after the Supreme Court did not rule on a plea asking for a deferment of the deposition.
Anil Ambani's Reliance Telecom had made an oral plea before an apex court bench headed by Justice G S Singhvi to get an interim order for exempting him from appearing in the case.
The court however said the plea will be considered only after it decides the petitions recalling two of its earlier orders barring High Court from hearing 2G cases.
A plea for deferring Anil Ambani's deposition, effectively dragging the trial, was earlier dismissed on grounds that the judge ruled that there would be no prejudice against him as a witness.
In perhaps the biggest scam in independent India, allegedly masterminded by former telecom minister A Raja, spectrum was given away at throwaway prices in 2008 causing a potential revenue loss of up to Rs 1.76 lakh crore.
While Raja, a number of government and private sector officials and firms face trial, a landmark judgement by the Supreme Court last year had quashed 122 licenses issued under the sale.
