Hi
1) The WILL shall come in to effect only after the life time of the Testator(the person making the WILL).
2) So what ever is the content of the WILL, shall hold no effect whatsoever till the testator is alive.
3) Now coming to GPA bypassing the conditions of the Principal, a GPA holder cannot act on his own accord and that too without the consent of the principal.
4) A GPA holder is mandated by law to act ONLY according to the instructions of the principal and NOT otherwise..
5) A GPA holder cannot act either arbitrarily or on his own accord. It is clearly against the Law.
6) The principal can revoke the GPA by merely issuing an advertisement in the news paper and also by unilaterally cancelling the GPA at Sub-registrar office.
Hope this helps.
