My brother has been cheating on his wife with pros ever since marriage, he is caught and they are filing for divorce, likely alimony, we own a business with 15 cr turnover, equal shares as it's pvt ltd, but I have invested and give my time more, what issues will I face now?

Net profit after salary and all all yearly 50 lacs,

me n brother as directors put 70k each in our account, rest profits roll down in the business and we take out whenever needed

He has a bad habit by visiting pros, now his mess is giving me sleepless nights

My own capital invest 3.4 cr, his is 1.2 cr but due to my parents forcing us, we had to be equal in shares, I am 29, he is 32.
