Welcome to CiteHR.com.
I am not only surprised and shocked at your query, but feel outraged !!!!
Could you explain in detail, why you need such an NOC ??
Which country are you located in ??
In India and other democratic countries; and any country which upholds Human Rights, such things can not be imagined.
Are you an HR professional ??
In that case you should know that to attain the status of a "wife", a woman must be an 'adult', and as such any adult does not require an NOC from any of her relative to work.
In case you are married, (I assume from your name that you are a female), did you submit an NOC before taking up your current job ??
Civilized world has come a long way, since abolition of slavery and gender-dominance/exploitation.
