The inheritance laws and customs can vary significantly depending on the country, culture, and religious beliefs involved. There is no universal answer to this question as it would depend on the specific legal and cultural context in which the family resides.
In some cultures or legal systems, the wife of the deceased son may be considered an heir and entitled to a share of the inheritance, especially if there are no other surviving children. In other cases, the inheritance may pass directly to the remaining sons or their descendants, excluding the daughter-in-law of the deceased son.
To determine the rights of the wife of the deceased son in this situation, it would be best to consult with a legal expert familiar with the inheritance laws and practices in the specific jurisdiction or community in question. Additionally, cultural and family dynamics may also influence the distribution of inheritance, even in the absence of strict legal requirements.
