A will is a document which states what a person would like to do with his/her assets, after death. If a person passes away without a will, the assets will be distributed according to the applicable laws, which may not be in accordance with what he or she wishes. If the person is a Hindu, for instance, the Hindu Succession Act applies; there are different rules for males and females. So for a male, assets will be divided equally between his mother, spouse and children. If he had intended any other distribution, it wouldn’t have been possible.
A will must be unambiguous and convey clearly how one intends to distribute his or her assets; it’s fine if it is in simple language. Priyamvada Birla’s will was less than two pages! No reason why our wills should be anything more. Every will requires two witnesses. The will can be registered, but it is not mandatory. A handwritten will is best as there is much less chance of its authenticity being questioned compared to one that is printed. It is also a good idea to get a doctor’s certificate on the date of writing the will, stating that the person is mentally fit and fine, so that this aspect is not questioned in future.
