Husband dessertion

It appears that your husband has found some other setup, there appears to be another woman in the game, not the mother-in-law, but an outside woman whom your husband is interested in.  

All this looks fine until it goes in print, on paper in a court of Law.

You have tried to talk to your husband and he is not available.

Its time to involve your elders in asking whats the intent behind this kind of behaviour.  A meeting of elders of both families is very essential  at this point.  Wherein you both sit and discuss in the presence of your husband regarding the issue at hand.  The boy's side need not be threatened of dire consequences [filing false cases like 498a, DV or lodging missing complaint].  Remember at all times this is a very delicate issue.  Jumping the gun and doing something like filing cases or complaint in police station will surely seal the fate of your marriage.

But certainly there is something more to than what meets the eye.  So try to find out why your husband is totally avoiding you, ah, that includes your parent-in-laws.

As you are living in India and he is living abroad, very a few legal options are left for you.  It is clearly a domestic violence case, in which your husband and Mother-in-law involved and hence, you are eligible to file domestic violence case against him for residential rights, maintenance (if you are not presently working) and compensation.  You can get residential rights in your in-laws' house as your husband is abroad.  Alternatively, if your in-laws object for your petition seeking residential rights on the ground that their place was never a matrimonial home and you are trying to trespass, then the court would ask your husband to provide rental accommodation.  But all the monetary benifit orders, at present, become unenforceable for the reason that is staying abroad and he does not have any movable and immovable property here in India.  But as he has not got permanent resident status there, he has to come back, and once he comes back you can execute them against his person and in the event of his failure to comply those monetary orders, he will be put behind the bars.  On the other hand, if you want to get rid of this relationship altogether, you  can file divorce case under the ground of cruelty, as the marriage was solemnized a year back, and if he does not turn up in this case, you will get ex-parte divorce decree.  Before concluding this, I say there are certainly problems to serve court notices and execute the decrees in the cases where one spouse is living abroad.
