I have conveyed it to them that i would not be able to pay 20 lakhs and they have tried telling me that they would also consult a lawyer and the case may be made into dowry harrasement.Would it be possible to file an affidavit stating that the sides have agreed for mutual divorce but alimony has not been agreed to. Both the sides wouls submit their income and liabilites statement and then the amount of alimony may be decided by the court?
Dont do the mistake of submitting your details before court.
It is her responsibility to prove her allegations and your income with documentary evidences for her claim.
If they threaten to slap dowry harassment case, you may ask them to proceed, you can challenge the same on merits becasue it would be an after thought false case which can be confronted properly.
There is no need to accept their exorbitant and unjustified demand.
Be stubborn and firm on your stand to not pay them even single penny if they harass you beyond tolerance level.
