Special marriage act is fairly simple..

You need to submit it in your local registrar office and her signatures and documents should be available...One applicants presence is compulsory.There will be 30 day wait period too..

Yes since Lucknow is your place of residence you can have it done there provide you have resided there for the last 30 days..Since you both have been married previously you might need to submit the death certificate of your respective spouses too..

Regarding the registrar coming to your residence.. I don't think it will work.. Normally some of them attend the marriage ceremony in the venue but you can check.. and yes they'll charge fees for visiting and will expect some bribe too..

Good luck Honesty and best wishes..
