Question Summary:
Is this Khula valid?

Question Detail:

Assalamo Alaikum,
I went to the jail due to a bankl default. Before that my wife was too good with me I mean I was everything for her. But on the other hand my in laws specially my mother in law turned against me even before going to the jail mainly because I was more loved in the family then her sons and that was all due to my humble and friendly nature. I am more learned and knowledgable than my brother in law and all the people young and old they usually take my suggestion in every walk of life. When I was in jail my wife went to her mother's place to life with our only son, after two months in prison I suddenly found my wife as if she doesn't want to talk to me. So I asked her straight so she said that she cannot compromise her families intergrity and that she wants to leave me and they have filed for Khula. I was released on the 21st of Dec 2015. And upon my release I called her to say sorry and apologize and basically wanted to make things look better. But she picked up my phone once and after hearing my voice she just blocked my numbers.
Some of our common friends have asked my in laws about the reunion and they say that the marriage has been dissolved by khula. A khula where I was not called to be heard, they all have my numbers my email addresses, my facebook profile, my twitter every thing through which they can contact me. And now if the marriage has been dissolved and I have been announce in the court as missing (which legally I am not) would this Khula be according to the Shari'a.
If my wife marries another person would it be legal or not. I referred to some ulema and they said that the second marriage would although be legal as per the law of the land but in the eyes of Allah it would be a zina because the khula was taken fraudulently.
Please guide.
Jazakum Allah

Assalāmu ῾alaykum wa Rahmatullāhi Wabarakātuh
A khula is valid only with the consent of the husband. In the enquired situation, you as the husband was not part of the khula agreement, hence the khula is invalid. Your nikah with your wife is intact. Your wife cannot marry anyone else. If she does so, the nikah will be invalid and be regarded as Zina. All the academic references are in the footnotes with the specific article on khula in Urdu. [1]
