Under Hindu Marriage Act or Under Cr. P.C Section 125 wife cannot be entitled to an interim or permanent maintenance if she is a working lady. The provisions under the Act are to ensure the wife does not live a life of destitute; she has to have a respectable income to support herself. Therefore, in case if she is a working lady then please ensure the following:
1. Collect documentary evidences like bank details, place of work etc., which proves that she is a working lady;
2. Alternatively, as an fyi, under Hindu Marriage Act, a husband can also demand for maintenance.
3. Before approaching a lawyer in Delhi, please have all the evidences beforehand wherein she is earning so that you may avoid maintenance.
4. You MUST attach all the documentary proofs/evidences of her earnings to avoid maintenance.
5. You may have to seek personal references to get a proper lawyer in Delhi.
Hope I answered your questions. Please let me know should there be any further clarifications required.
Thanks,
