Is being ex-parte a good idea?

Just few quick question .

 Can court award alimony without looking at income status of husband ? My wife has filed for Divorce and Child Custody and asked 8 CR.  As one time alimony .

She states in her divorce petition my annual income as 2.8 cr. Per year where the fact is that my income is approx. 15L PA. and I file the ITR for the same.

I have yet to respond to the petition and make the appearance . I have already filed RCR before she had filed the Divorce.

 Now one of the lawyer has advised that since  she filed the divorce and there is no way I can get immediate custody of my son (6 years) old  I should be ex parte for this

Case and let them have the choice if they want to continue with ex parte Divorce .  My question is how will court award alimony in this situation? After being ex parte can I still have my visitation rights ?

Can I still file for Child custody separately ?

 Expert help is appreciated .

 Thanks
