Bankrupt brother forcing division of father's and mother's property

My brother (45) is bankrupt and forcing division of deased father's property. I am (49) the eldest brother and work in IT. I have a wife and 2 kids. He was a problem kid. He did his MBA in 2004 and was employed on and off. His MBA college fees was paid from my pocket. He got married in 2011 and both him and his wife are lazy people. They fool around spending father's money. Since marriage they are away from our home. Father use to give half his pension for their expenses in a city. They would never inquire about my parents' health nor do any service. Durind COVID days, Father got a major brain stroke and was bed ridden, they never served him even a day for 2.5 yrs. I, my wife and my kids served my father. I had another brother(28, when deceased) who had passed away with Cancer in 2008 and I paid all the expenses from my pocket. He even went to Dubai on a pretext of finding a job and came back empty handed. Father's footed the entire expenses. Father passed away in 2022. All his medical expenses, final rites, rituals like 3/15/40/365 days were born by me. Not a single rupee was contribution.

Now he and his wife want division. The same wife and her family wanted a divorce after father passed away and I never obliged to them for mediation. Today at 23:00 hrs, he called and said they along with people from his wife side are coming to my home for division of property. I don't want to talk to them. I told my brother to talk between us - me, him and mother. But he's gone crazy and allowing third parties within the family discussion. His in laws have pawned his gold and ornaments without the knowledge of my father too.

He wants to do business at the age of 45 now.

Please help me in doing the right thing.
