Any person of legal age, having direct and personal interest in the correction of a clerical or typographical error in an entry and/or change of first name or nickname in the civil register, may file the petition. A person is considered to have direct and personal interest when he is the owner of the record, or the owner’s spouse, children, parents, brothers, sisters, grandparents, guardian, or any other person duly authorized by law or by the owner of the document sought to be corrected.
In short, it can be filed by the person whose birth certificate needs to be corrected provided he/she is of legal age otherwise, he/she needs to be represented by his/her parents. Your spouse, sibling, grandparents, legal guardians can also file for you. But if the person cannot personally file the same, it is best to secure a Special Power of Attorney from a lawyer authorizing someone else to do it for him/her. The person filing for someone else should also bring his/her valid ID for identification purposes.
