According to the petitioner, he was adopted on 19.08.1980 by one D.Jayaraman and J.Thrisarani (changed her name as Raniammal by Gazette Publication Issue No.12 dated 27.03.2013), who died intestate on 05.07.1983 and 18.03.2015 respectively and he is the only legal heir to inherit the property owned by them. On 23.10.2020, he applied for legal heir certificate through online, but he did not receive any reply. Subsequently, through RTI, the petitioner came to know that his application bearing No.TN-7202010232392 has been rejected, as he did not submit any proof to the effect that he was the adopted son of the deceased Jayaraman and birth certificate as well. Feeling aggrieved, he has come up with this writ petition seeking a direction to the fourth respondent to issue the legal heir certificate by processing his application, based on the documents, such as, school records, family ration card, etc.
