Existing valid marriage hote hue second marriage kar lena generally big legal problem hai. Bahut systems me yeh bigamy/polygamy ki category me aata hai (with some personal law exceptions).

Consequences:

• Criminal prosecution possible,
  
• Second marriage often void treat hota hai,
  
• First spouse ke paas divorce, maintenance, compensation ka strong ground,
  
• Second partner bhi victim ho sakta hai agar usko truth hi nahi bataya gaya ho.
  

Children born from such unions ko courts ne usually better protection diya hai – unko inheritance, legitimacy ke kuch rights – taaki bachche parents ke choices ka full burden na uthayein.

Safe approach simple hai: pehle existing marriage ka legal closure (divorce/annulment), phir hi new marriage. “Sirf rituals hue the, law ke hisaab se shaadi nahi” jaisi arguments later heavy scrutiny face karte hain.
