Dear Ms.Sangeeta M.V,
1. Once partition of ancestral property has taken place on oath it cannot be revoked.
2. You had absolute rights over the property that your husband had bought in your name. Since it has been the subject matter of an agreed partition deed, it would make it very difficult to cancel the partition deed.
3. However, a partition deed can be setaside/cancelled if you and your other sons can furnish proof that the value of properties split between the surviving co parcenors were not in a right proportion at the time of execution of the deed.
4. In my honest opinion, revoking a partition deed after 17 years of its execution is a futile exercise.
