Answered by: Alimah Umm Abdullah
Can the person marry the same woman twice without divorce happen, so make a new nikah and new certificate new party as well nothing was in secret?
In the name of Allah, the Most Gracious, the Most Merciful
In principle, nikah is done when the words of ijab(proposal) and qabool(acceptance) are heard in the presence of two male witnesses or one male and two female witnesses.  Once this process has taken place, two people are married and there is no need to repeat the process again.
Only Allah Ta’ala knows best
