I agree with ehho2. Tyo Din, I think your friend case is not straight forward, he need to contact with lawyer for anything related to his ancestral property. According to law in Nepal, he owes his wife the property after the division(ansha banda). If your friend do not want any property from his parents in Nepal and it had been mentioned in Ansha banda(before the divorce) , then it is different story.

In short, there may be different hidden angles in this case, so I would suggest your friend to consult the lawyer.
