Dispute on daan patra land what to do

I am Central Govt employee, posted in Goa. My native is Jharkhand. I am employed since 2012, and i had bought daan patra land on my wife's name. Now, we want to sell the Daan Patra land, but my eldest brother is creating dispute in this. He is filing case claiming that land is bought by income of Father, so liable to get divided. This amount or property which is on my wife's name is bought by father's income and not mine. If he files case, it will be huge harassment for we husband & wife, going and coming from Goa to Jharkhand. Now we both are working in Govt department, loss of holidays, up downs. How to avoid it, we also want my eldest brother to taste this pain, i want him to do up & down from hometown Jharkhand to Goa for some case, then only he will understand. Kindly guide.
