When my ancestor married in january 1870 there is a special line in Church register

at parent s agreement it s written > consemtum cum tutoris <

what does it mean ? I mean he had parents , he was 23 years old so age to mary , so how to explain ? why he needed a special authorization to marry ?


thanks
