Law relating to Will is a difficult and complicated branch of law. It is mainly because Will comes into effect only after the death of the person making it and it is many a time drafted by someone with little knowledge of law and command over the language. Both of these factors altogether make it necessary for another person or the court to interpret the intention of its maker.
Even Wills of some eminent judges have come in to dispute before the court for want of clarity and legal perfection in them. Therefore accurate understanding of the law of the Will is necessary to make it foolproof or nearly perfect and insulate it from misinterpretation when it is put into operation at a time the maker no longer exists to clarify what he had indented to.
