1. Since you're coparcener your share in the property is crystallised and it cannot be defeated by way of sale.

2.Now since the court has imposed injunction on sale you can remain assured of your sahre which would be determined on final adjudication of the partition suit.

3.The proeprty sold can not be returned back as your consent is there when you signed as witness in those deeds.

Court fees is state subject and varies from state to state

2) if your share in property is Rs 3.15 crores the court fees would be Rs 3 lakhs

In the the event of legal necessity/benefit of estate the karta can alienate joint family property. However such an alienation can be challenged by the continuing coparcenors as not being for legal necessity or benefit of estate

2)you can claim your share in sold out property if sale was not for legal necessity or benefit of estate

You can challenge the sale of the property if the same was not in interest of the estate or was not a legal necessity.

Court fee will be around 3 lakh. However, if you do not have sufficient funds to pay the court fees you can sue as an indigent (in forma pauperis) (Your share in this particular property won't be counted towards ascertaining your assets)

Hiii, file a suit for permanent injuction and partition to restrain him from selling the property .. If you want to file a recovery suit for 3.25 cents the stam duty will be approx 20 lacs

As a karta he has sold the property for the benefit of the joint family.

You can ask for partition and separate possession of the residual property now.

Since you have signed as witnesses in the properties that were sold, it is very clear that you are in the knowledge of the sale of properties.

Hence you cannot legally claim any share in the proprieties already sold.

How much stamp duty I have to pay if my share is of RS. 3.15 CR.

Stamp duty is a state subject, you may enquire about it from the local sub-registrar office.
