Probate

My father made a Last Registered Will in favour of my mother 9 months back (Dec.’ 2018) wherein he clearly stated that his house with land to be handed over to her. After a month my father expired in Hospital. Since the will was to be “Probated,” accordingly an advertisement was published in the Newspaper 4 months back. Similarly, 2 months ago, concerned departmental Person from District / Subdivision Court had come to the house to do necessary verification of everyone including my mother. Since I along with my mother & sister were at home, He took our signatures together with Xerox ID proof of all. I had received the letters on behalf of my two brothers who were out of station for a week. Death certificate of my father, his Aadhar card along with Aadhar card of my mother her PAN card, Certified Copy of the DEED ( Property purchased by my father) will be placed in the Civil Court before the Magistrate / Judge. The 1st hearing will be done within 10 days. Will the “Registered Will” be easily Probated or is likely to face any Objection? Plz. guide. Thanks !! Sushil Gupta..
