demolition

we live for almost 20 years in a house where the land is owned by siblings including my grandfather. As time goes by and more things happen they decided to divide the lot..Unluckily the land where our house is standing was the share of one of my grandfather's siblings..In a situation that they are very mad at us, they want us to move out from that house within six months starting today. They told us that they will might pay us maximum 5,000 for moving out and nothing more. I want to ask if we agreed to move, do we have the right to ask them to pay the expenses we used when we build our house?pls i need an idea..thank you
