Power attorney

Was the family settlement registered? If yes, it is binding upon sisters as well brothers.

Show the deed of settlement to a local lawyer and seek guidence/advise.

Dr. Vashista Sir, the author is referring to power  of attorney deed and not family settlement deed.

@Imran

Please note that the principals of the power of attorney deed executed in favor of the agent can very well revoke the same anytime by just issuing a notice to the agent and executing  cancellation deed in the concerned registrar office, thereby the poa deed will be nullified.  the other aspects that is, if they would approach a court for partition etc, to be made know from them only and in case they proceed through court, as a share holder, they can very well claim for their rights and the case will be maintainable.

Dear Kalaiselvan,

I fully agree and appreciate your observation that the query peratained to "Power of Attorney" as per headnote. Similarly in the later part Mr. Imran states,  "All sisters signed Power Attorney ..." "..."...by any Court of Law all sisters can able to get Power of Attorney back .." ... "or as per Power of Attorney, brothers will have all rights on land as per law.." Thank you for correcting me.

However, the query of author is observed to be confusing as Mr. Imran stated in the body of the query inter alia, "...they made final agreement between brothers and sister to divide this land in three parts,.." accordingly I opinioned it to be a "FAMILY SETTLEMENT".

In this context, the attoney can proceed/act as per covenants of the said "Power of Attorney.." during its subsistance, which is revocable. However, any action taken by the attorney during the life of said POA shall be binding on the principal/grantor/executant.
