My

wife name is Jamuna Pathak in 10th pass marksheet of Up board.

In voter id her name is Yamuna Devi w/o Vijay Kumar Tiwari.

Now she want to change her name to Yamuna Tiwari.

Sir, what is the right legally process to change names. From which end it is legally for documents. correction of voter card will be sufficent or correction in marksheet.
