Wife is not coming back with my 6 month kid from her parents house.

My name is Deepak and I got married 3.5 yrs back. My in laws house is in Jaipur and my Wife was also working in Jaipur even before the marriage. At the time of marriage finalization, my Father in law and my Wife told me that here some certification was going on along with the experience benefit of current job for which she has to continue with the same job for next three years till Jun 2017 and after completion of the certification, my Wife will come and stay with me. During the time of marriage I was staying at n delhi and doing my business there in work contracts. But in Dec 2016, unfortunately my Father passed away in a road accident and I am the only Son with two younger Sister who are married and well settled in their family. Due to the unfortunate change in my life, I returned back in my home town and living with my old age Mother. In parallel, I joined the job in my home town and after my father's death and my return to my home, I talk the my Father in law and Mother in law and also my Wife to come back to me and stay with me but they all kept a silent on their mouth and ignored all my efforts and request. Even during the period of her certification process, she used to come only two times in a year to my home and that to only for two days during holiday- Diwali festival. Now, I have a 6 month old child with my Wife and she is refusing to come back and stay with me. Even her parent are supporting her so much and they are straight away saying that she will not go back and we wouldn't let her leave her job from Jaipur. Even they are trying to haress me and trying to bound me to come and live in Jaipur only. I am already a facing many problems that my permanent residence house in Ajmer, where I am staying with my Mother, has an ongoing case of property dispute on our house and another case of my fathers accident is already going on. Both the cases are proceeding in Ajmer district court and my Wife and their family already aware of my present above issues, that I m facing off. Moreover my Mother is centimentally down and haven't come out of my fathers loss in our life. Even above to it, I tried and talk to my Wife and in laws and written letters to them to send my child and my Wife to send her back but they are not sending her back. She herself also says that I will not come aback without any specific cause or reason else except following her paerents guidence monotonous mindset. By doing this, she is doing a mental and emotional torture to me and my Mother and specially doing an injustice with my 6month old kid. Last she came to my house was on mar 2017 only during holi festival and thereafter till now, she haven't returned. Recently, I came to know from my boss that My Father in law had called my boss and requested him to fire me from my current job with a reason that I myself get stressed out of loosing my job and come back to Jaipur and live as a ghar Jamai. Kindly suggest that in such situation, what should I do?
