Prpoerty dispute

The amedment introduced in Hindu Law in 2005 gives equal rights to female coparceners even after marraige. but it does n't apply to the arrangements effected before september or october or december 2004. I don't recollect exact date. In your case your sisters already by consent released their rights in writing. You can produce the same in the court. Moreover, a considerable time has also elapsed which brings law of limitation in picture and she can not file a suit for partition after all these years. The suit itself is not admittable and should be dismissed at first. Follow the advise of the lawyer u have engaged for the same.
