In laws property

Respected experts, I regret for repeating the problem. Experts have already clarified that daughter in law has no claim/right in parents in laws property. This relates to mostly in DV case in seeking right to residence. But my question was different. I would like to know whether parents in laws property can be considered in deciding the quantum of permanent alimony. ( Financial capability). Because Alimony can enforced against husband , not parents. Court directs husband to show details of joint family properties. Isn't it higlhy illogical and injustice. What should be done now. Please guide. Any judgement etc etc. Your valued reply will be of great help . Regards.
