I paper married someone and later I divorced her. Later, got a wife from back home but didnt tell her about the paper marriage. Did I do wrong?

As a matter of precaution, we advise that before your wife gets information
of the paper marriage, you indicate to her the incident if that will not be
a cause of dispute between you and your wife.
