Father made unequal distribution of property how to check it

Hello Sir, I live in United States but my hometown is in India. I suspect that my father and mother transferred all their property to my brother a few days back without telling me. I have a few questions regarding that 1) Is there a way for me to check who is the owner of which property from government offices in my hometown ? 2) if he indeed transferred it to my brother can that transfer be stayed or reverted in any way ? 3) Some property was in my mom's name and some was on my dad's name. All was self acquired and none was inherited. Can my 3 sisters also claim a portion in that property even if my parents are unwilling to give them any ?
