If you want your wife to stay with you than state to the judge that you are ready to keep her with you . When you state that you are not ready to keep her with you than the judge would order you to provide you with a rental accommodation .
Next .
1. you have stated that you have your own house .
2. you have not disclosed the fact if you are working and your wife knows your place of work or your employer .
3. if you are into business than your assests can be attached ,
When maintenance order is awarded ,and the same is not followed than
a) The court can attach your property until , unless you pay the maintenance .
b) The court can order your employer to deduct the amount from your salary and pay it to her .
When all the above options have failed than the question of going to jail comes into picture one month for every default u/s 31 of DV act ..
1. By the way whats your age i hope you are not young else you may get sodomised over there since everything is available except s*x .
2. Cigrates and beedies can be made available .
3. Calls can me made on the quite .
4. you can pay and have good food .
This is not my experience but what i have heard from people once you finish your first term in jail do let us know your experience on this forum :-)
