Marriage is a social and legal relationship between two 
consenting adults. There are legal regulations to maintain 
the sanctity of marriage and to prevent actions deemed 
offensive to public morals. Every legal system, therefore, 
presents a conception of marriage, which states what can 
validly constitute a marriage, stipulates actions that are 
wrong, and provides ground for its dissolution. One of 
these vices is bigamy. This paper through a textual review, 
focuses on bigamy and the legal implications of adultery. 
It examines bigamy as a subset of polygamy, which can 
either be polygamy (where a man marries more than one 
woman) or polyandry (where a woman marries more than 
one man). The paper finds that, in whatever form it occurs, 
bigamy is the direct opposite of monogamy, which is 
marriage to one person. Bigamy is generally a criminal 
offense, and it is governed by the Criminal Code of various 
southern States excluding Lagos State in Nigeria and the 
Penal Code of various northern states in Nigeria. Bigamy 
is distinct from adultery. It is a criminal offence if it is 
committed knowingly. The offence of bigamy places 
prohibitions on situations where a married person purports 
to marry again. It has a long history within the Western 
legal tradition. Nigeria is a polygamous society and in that 
light the offence of bigamy was not known. The research 
revealed that the offence was imported into Nigeria as a received English Law. The research recommends and 
identify how court interpret and apply the Laws on bigamy. 
It further looks at the cultural, social and historical contexts 
that shape the laws and attitude toward bigamy in each 
country of focus, this include exploring how religious or 
traditional practices influence the legal framework and 
enforcement of bigamy laws.
