Will

In a Will  witness name and address is a must although it is not mandatory.  Witness of the will evidences that in his presence the testator subscribed and sealed the will and the testator signed in his presence. which makes the will a valid one and has no discrepancy in it..

As per law two witnesses are mandatory.  But there are citations that atleast one witness is enough.  If there are no witnesses at all, atleast it should be registered will.  To some extent it will work out. 

I reiterate my posted opinion made earlier. Signature of the witnesses upon a will is not mandatary.  Because the term mandatary means " one who acts gratuitously but is entitled to be indemnified for expenses incurred in carrying out the mandate " .  NOW LET US SEE WHAT IS MANDATE which is to be carried out by the witness of a Will ?  Here we see the definition of the word MANDATE according to legal parlance and Roman & Civil Law  is " a written command given by a Principal to an Agent specifically a commission or contract by which one person ( the mandator ) requests some one  ( the mandatory ) to perform some service gratuitously, the commission becoming effective when the mandatory agrees".  Besides, I NEED MENTION FURTHER a provision in a statute is said to be mandatory when disobedience to it or want of exact compliance to it, will make the act done under the statute absolutely void. According to such explanatory position of the term  " Mandatory " I totally disagree that the witnesses required in a Will is not mandatory but it minimizes the questions of challenging its genuineness before the court of law at the time of taking probate more particularly  to prove that the signature of the testator  was taken not under duress or otherwise..

A Will in order to become valid legally has to be witnessed by a witness in whose presence the testator has signed and sealed the Will, if not it becomes legally invalid.
