My grandmother made a will in my favor for her house in Kolkata how to get probate

You can file a petition for probate before the District Court or the Calcutta High Court in Kolkata having jurisdiction, depending on the value of the property. Under West Bengal Premises Tenancy Act 1997, a probate is mandatory for a will dealing with immovable property in West Bengal. The petition must include the original will, death certificate, and details of all legal heirs who must be served notice. The court will examine the witnesses to the will and verify the genuineness of the document. If any legal heir contests the will, the court will conduct a trial before granting probate. If probate is refused, you can appeal to the Calcutta High Court under West Bengal Premises Tenancy Act 1997.
