According to the situation that you've explained above let me enlighten you about certain acts and rules. Firstly, if the property you're talking about here is self purchased by your father-in-law, then your husband becomes the legal heir along with his respective siblings (among which the property shall be equally shared) according to the Hindu Succession Act,1956. However, if by any chance the owner or the person who purchased the property (i.e. you're father-in-law/mother-in-law) makes a legal 'Will' stating that the property shall be given to their daughter only, then your husband could be deprived from his right/share from this property. But, if the concerned/disputed property has been purchased by your husband's grandfather or ancestors, then it automatically becomes his ancestral property and in according to law, no one can deprive one's right/share from ancestral property. Thus, if it is your husband's ancestral property then he cannot be deprived of his right/share/interest from such a property, even if his parents don't will so.
Here are some few case laws which are related to your query, please do check for a better understanding of the concept.
