1) You only can deny the return statement which you can not as it is true, You cant question the source of document. It may have been derived from your own files, mails, CA, Returning officer or by the some one who is working in the income tax department.
2) As far as her leaving the job is to be considered it does not matter whether she is still working or not the main question is whether she is capable of earning or not and how much? Can she maintain herself out of her earning capacity as at par with the standerds of her married life or not? As law gives her right to enjoy the same status as she was enjoying after the marriage and if she is not she has to be compensated with the differance amount.
It is better you prove her capabilities to earn which only can be established by showing her qualifications and past history of employment. Even if she is a mere house wife with a good qualification in a recent judgement of Delhi court she was entitlled for only a year maintenance and within that time period she was ordered to find a job and stand up to maintain her self. So do not worry just chose a good Advocate who can represent you properly in the court and can establish your contentions properly.
