One out of three brothers captured entire property.

I am son of youngest of three brothers. They have a common house.The eldest brother has always been more dominant in family over all the matters. He is unemployed and is accused of domestic violence. His children and wife have left him because of his arrogant/violent behavior.It has been over 6+ years, The two younger brothers have moved out of the house. The tyrant brother continues to live there. Since the tyrant brother is unemployed he constantly ask money from younger brothers. Initially the younger brothers had fulfilled his needs but now they refuse to help since they have their own expenses. Tyrant brothers children and wife don't support this nonsense and have broken all ties with him. Now the issue is the Common House. The younger brothers suggested the elder brother that they should sell the house and divide the money equally. This will help the tyrant brother can get rid of the money problems. But the tyrant refuses . He wants to capture the entire house or the major part of it. This one time all three had agreed to sell and divide equally. People came to measure the property dimensions, then this tyrant brother verbally abused and insulted everyone on scene and asked them to leave. This has happened multiple times . Now this tyrant brother is constantly texting my father, the youngest of three , to transfer money in his account so he can pay his bills. My father has a soft corner but we have asked him not to give into his demands. The tyrant brother is mentally harassing us from past 1 years. He wont let us split the property . He wont stop asking us for money. Please advise what to do.
