No business proof is ground for divorce ??

Currently i have new business in name of Private limited registered company since Nov 2019. Married in 2009. But from last 8 years before new registered company I don't have any business proof for which I had engage in real estate brokerage work, car dealings and passenger transport agents. My income are high till 2017 then after business slow down and issue of loans and lenders rises due to which I lost my flats and i am staying in rented flat. As I earned a lot till 2017 we always go to holidays in abroad or any where else in India. Now I am doing my business with all legal proof and records since last year. But seeing my financial situation occurs as in 2019 and all things lost with my flat due to loans, wife family and in-laws take away my wife without reason since Nov 2020 and now asking me to show the previous business proof of last 8 years so that same financial situation will not reoccur as happened in 2019. And In-law's are saying without proof that you must be fraud and enjoyed last 8 years by looting others. They are saying show any proof so we will return your wife. Now I am doing well. I already filled IT returns of this year and earn good income per month. But don't have any old business proofs. So I want to Know that is having No proof for previous or old business is ground for divorce. How I can go ahead with their demand and How I can reply to their questions, Pls suggest.
