Unregister will is valied?

Yes , Registrationof Will is Optional as per Indian Succession Act

And Registration Act 1908 as well

Unregistered and  hand written will is equally valid on par with registered will..

As per the registration act, section 18 (e), yes, unregistered wills can be perfectly valid. Registered wills are different only in that they are backed by legal evidence as to their existence. The original copy is kept in the sub-registrar's office at the will being registered, and hence protected. (In case the copy of the will in possession of the testator is destroyed or tampered with.) There should be at least two attesting witnesses to the will, who should have signed the will in the presence of your grandfather so as to certify that they witnessed him signing the will or having it signed as per his directions, be it registered or not. If this is the case, the will is valid.

Absolutely it is valid. If you are in AP I think probate is not required.

"WILL" in common parlance means "expressing the future tense."

In leagal meaning ""A will or testament is a legal document by which a person, the testator, expresses their wishes as to how their property is to be distributed at death, and names one or more persons, the executor, to manage the estate until its final distribution."

The primary aspect of a WILL to be legally valid is 2 persons attesting witness to the will when the testator signs in their presence. When only one person has signed as witness then it is not a valid Will. ... A will which is not registered is valid if it is signed by two attesting witnesses.
