Wife is sending me notice for unlawful claims even after filing divorce without any claim in prayers

Hello everyone, This is a long one. I request you to kindly read this. I am a 37 year old male. I started dating my wife in December 2012. She professed her love for me in March 2013. Soon after she urged me to speed up things. I got married in July 2013 (legally) and in Jan 2014 (socially). By then, I had already worked in a reputable IT firm for 6 years, but when I met her she was unemployed. Before marriage I had told her that I was interested in setting up a business and it will take time to settle. I advised her to take up a job. Eventually in March 2014, I went ahead to start off my business and by June i quit my job. I had invested a large sum and loaned a better portion from friends. She got a job offer in the same city but she did not take it up and gave vague reasons. The expenses on the domestic front were extremely high. She constantly pushed me for VISA process for another country. Gradually it became difficult for us to survive. I was trying very hard to pull through. In January 2016, she left for another country on the grounds that she had to earn, as I was not able to support. Please note that during all these years I was constantly looking for better job opportunities too, while simultaneously freelancing. For next 3 years it was on and off and we would meet once in 3 months and the problems grew by leaps and bounds. I would ask for divorce and she would always turn it into a fight. Eventually in October 2019, I moved to my hometown with my parents. We had no physical contact since April 2019. In December 2021, she sent legal notices stating that I have to settle about 50 lakh rupees in claims to which my lawyer responded. I also tried to settle it mutually and peacefully. In April 2022, she filed for divorce (legal filing at a family court) without any claim in the prayer. My lawyers advised me to go ahead with the process, as she had not asked for any claims. However, she had mentioned stories of Rs. 50 lakhs claim in the grounds of divorce section, but nothing in the prayers. In July 2022, I got a job offer from a reputable firm and I decided to join. In September 2022, first week I moved to another city to join this job. As of today, I was sent another notice from one of their attorneys, and again they have raised the claim to the amount and asked me to settle within 15 days. I have conveyed this to my lawyers but I want some opinion from the public forum of experts too. Please advise.
