Dear Sir,
The best solution is to enter into deed of family settlement / partition so that you don’t have to go to court; but if any such attempt fails :
1. You can file a partition suit claiming your share of the property,
2. Get the property partitioned and divided by meets and bounds,
3. If the property is not a dwelling house where all the co-owners are staying together, you can sell your share to a third party,
4. If it is a dwelling house, you shall have to offer to sell your share to all the other co-owners at the same price which you are getting from the third party and if they refuse to buy the same, you can sell it to the third party.
