In India, filing for probate of a Will is not mandatory; it depends on various factors, including the location of the assets and where the Will was executed.
If the Will was created within Kolkata, Mumbai or Chennai; or if the Will contains immovable property located in any of these three jurisdictions, probate of the Will is mandatory.
Furthermore, if the deceased person's assets are located within the jurisdiction of a competent court (usually the district court), and if there are disputes or concerns about the validity of the Will, obtaining probate is advisable.
However, in cases where the assets are outside the jurisdiction of a competent court, or there are no disputes, it may not be necessary to file for probate. It's crucial to consult with legal experts to determine whether probate is required under the Indian Succession Act and which court holds jurisdiction in your specific case.
