Man & woman got married last 2003. They had a child born on 2006. Man left his family last 2007 when woman discovered a 3rd party on man's side. from then on up to present, they live separately.
last year, man discovered that woman got pregnant and bear child this year to unknown father. they still have a little communication because of their 1st child whose now 7 years of age. man hesitant to confront the woman since he doesn't have docs to support these evidences. He only saw the photos on FB account of the woman.
1. since woman used his surname for the birth certificate of this 2nd child, is it possible to appeal and not to use his surname.
2. since there is a child born outside there marriage, is it possible to use this for filing a case? adultery?
3. or later on, can this be use for filing for annulment of the man?
Hoping for your legal insights.
