My father died recently at the age of 92. His wife died 15 years back. He has five children. The eldest is a daughter followed by two sons again a daughter and the last one is a son. The children are aged between 67 and 45. His eldest daughter was married in 1968 and the second daughter was married in 1975 and both of them are settled in their lives.
All the three sons are married. My father divided his ancestral properties among his sons and himself. The second son got his preferred share and got himself discharged from the family by giving a letter. The last son lived with my father till the end. The eldest son was associated with the family affairs throughout. My father gifted/willed his share to the eldest and youngest sons recently. The eldest and youngest sons are only looking after the litigations in respect of the properties. As legal heir certificate is required to continue the litigations, kindly enlighten whether it is advisable and correct to get the legal heir certificate only to the eldest and youngest sons as the other children are in no way connected with the affairs of the family by declaring the facts in an affidavit to be enclosed with application to get the legal heir certificate.
