Want to sell house but one brother living in it doesnt want to sell

We are 3 children of our parents. My father who owned an apartment in Delhi died and gave it to his wife. We have the relinquishment deed. My mother died in Oct 2017 and said in her will that the property should be sold after her death and be equally divided between her 3 children. My oldest brother and his wife are living there and they have no intention of selling it. My brother doesnt have any income and his wife is making very little money in a factory. Their daughter is married and living closeby. M other brother is living in the US and wants to sell the house. I would also like to have my share but do not wish to drag my oldest brother in court for long time or cause any harm to him. What is the procedure and how long will it take? What if my brother does not vacate the house? He makes the buyers also go away I think. How much would it cost us? I am unemployed and living in Canada.
