Will Preparation is the first step towards ensuring a easy succession and helps to avoid disputes or fights within the family after the death of the testator. Will preparing is governed by the suitable personal law of the testator.
A Will is a judicial document that expresses your desires related to the dissemination of your wealth, the whole property you have, and could extend to the care of any minor children.
A Will Preparation in India can be executed on a plain paper and remains fully valued even if unregistered, i.e., it is not mandatory to register it under law. However, that does not inhibit a person from registering the same simply to put an end to any doubts raised over its certainity.

If one wants one’s Will to be registered, one has to visit the sub-registrar’s office with witnesses. There are sub-registrars for different districts and one has to find out from the concerned office about the one who will help in registering it.
Most of the people do not have a Will and do not realize the financial mess that our loved ones could be fated for in case of an unexpected event.
Will writing is to make sure that your hard-earned movable/immovable wealth is distributed to your loved ones (beneficiaries) as per your desire after your death.
