No no Im legally separated with my partner, i.e we have already filed for divorce.
So in that case, I will select legally separated and "NO" in previous marriage/cl relationship I believe.
Also, just needed an advice: my marriage was never registered i.e just a religious ceremony and also it hardly lasted for a month and we have been separate for more than an year since. So can I simply avoid these hassles and declare myself as 'Single'?? Because for a married couple, marriage certificate is mandatory as per their requirement
That may be true, however; it may be construed as misrepresentation, if found. In india, a Hindu marriage ceremony is just as valid with or without legal registration.
