Property belongs to father can son take loan on that property

We are from Maharashtra, pune district. My father in law has 60 acres of agricultural land. He has 3sons and 3 daughters. I am the youngest daughter in law. My eldest bro in law has taken loan on that entire land without our consent and has started a huge business. We never get any share for any profit made by that land ever and we didn't ask for it either but now we have faced a loss in our business and we are homeless staying at my maternal place. We asked for our share but they refused. They say we must go there and do farming thats the only way we can benefit from the land. Plz advice.
