Thank you for the clear advice. I would like to update you on the sequence of events, in case it would prove beneficial to any fellow members.
Sequence of Events
My wife was relieved from the office a day after this. She was refused any other documents other than a standard relieving certificate with the date of joining and relieving, and a payslip that they managed to set up. Further calls to the company were not answered by the HR or MD, and we were told that they didn't have the 'time to waste' on this matter.
So, I took up this matter with the Labor officer. My wife and I approached him with all documentary proof like a bank statement of the amount deposited by the company, hard copies of all email communications with the company. The labor officer was quite understanding, and after listening to all we had to say, asked us to give a written request to the Assistant Labor officer explaining the matter. In the letter, we detailed the amount paid and attached a copy of the payslip given at the time she was relieved. We submitted the request and were informed that we would be updated on any progress.
Within a week, we received a call from the labor officer, who informed us that he had visited the company to collect details and verify the information we had provided. He also assured us that he would contact us with any updates in this matter.
He followed up on the case and kept us informed periodically of the progress. Finally, we were asked to meet him on a specific date and were informed that the settlement would be done on that day. We were also informed that the company officials would be present at that time. We went there and met the labor officer punctually. The company HR arrived half an hour late, and we were asked to come in together to discuss the matter. The labor officer instructed the company HR to provide the full 12 weeks' payment and informed them that the policy they were following was legally invalid. He emphasized that while the company could have a different Maternity Leave Policy, it should not be inferior to that of the official Maternity Benefit Act, as Mr. Madhu mentioned in this thread. The HR issued us a check, and we were requested to provide a written letter stating the issue had been resolved and we had no further concerns. The case was then closed.
Thanks to all the great helpers here at cite hr, we were able to win this battle. Thanks to you, more people will benefit, and individuals will not be deprived of their rights!
