Property Dispute

We are staying in joint family with our in-laws.My in-laws had eyes on my salary,since my husband refused to share my salary with them they started depriving him of all rights at home. He is the eldest son in the family. Since the time we got married my two younger brother-in-laws have been influencing my in-laws in negative way. They have managed to transfer all existing property on their names including the flat where we are staying through Gift deed. Also what ever new property my in-laws have bought in recent past they have taken on names of the younger two sons. In short my in-laws don't want to give any share to my husband as i was doing job, also my husband had managed to buy some property on his name before our marriage. They think we have enough so we should not get anything.According to us this is injustice with us. Please suggest legally does my husband have right in any of the properties.My father in laws property was self made by him except one of the property which was of grandfather later that was also transferred on my mother-in-laws name.
