I was married for more than 25 years, and i have encountered a problem this recently when my wife has secured marriage certificate at NSO.

I am presently working here in Qatar from early 90 to present, during the mid 90's I was nearly involve having an affair with a widow who is also working here in qatar but her contract was terminated before our affair will materials. She return to the Philippines and since she is the bread winner of his family, i  agreed with her that  i will apply  her her visa so she could return here and look for another job.  She produce a fake marriage license that we are married. Unknown to me that it was registered at NSO. Do noithing happens in taking her here in qatar because i have thinks many times and decided that this is not a good idea.

My question is, how could my original marriage be registered to NSO. and Second, how could i cancel my registered fake marriage certificate at NSO.

The second marriage never took place legally and tampered the formal requisites of legal marriage. This can be nullified thru court as it was void in the first place.

Late registration of first marriage is possible.
