No need for disclosing the Company account details by yourself. The person Income Tax account details are good enough proof that the husband need to give. The wife if disputes the ITRs of husband, the onus to prove these are on her, that she will not be able to do. The allegations about the income in crores made by husband have no significance that is always done by the wife and her counsel, in order to extract maximum out of the husband, but what court will see the ITRs of the husband to decide his income. The Court shall also look in to the ITRs of the wife to ascertain her income too and only order for maintenance to her if she does not have sufficient means to maintain herself up to the standard of living the she was having while living with the husband in the matrimonial home. The maintenance for living doesn't mean that it will be given for her extra ordinary spending and throwing money of extravagant lifestyle this has to be for daily routine spending required for reasonable decent living.

Adv Mahajan has given the right suggestion,, act accordingly. Nothing more to add at this stage. Mr Pallavan post UR query in a new thread instead of intruding into this query.
