d by the social and religious norms of society . Therefore, the sanctity of marriage is a well-accepted principle in the world community. Marriage is the root of family and society. However, by looking at the types of marriage in Nigeria, therefore, unlike most European countries two marriage systems are recognized in Nigeria, namely, monogamous and polygamous . These two marriage systems differ fundamentally from character and incidents. It is therefore important to take this duality into account in any consideration of marriage laws in Nigeria in order to avoid confusion. In all cases concerning marriage, the lawyer in Nigeria must first determine the type of marriage involved before he can apply the appropriate law . However, monogamous marriage is Nigeria is the same as in England. It is marriage that Lord Pensance called voluntary union for the life of one man and one woman to the exclusion of all others, whereas polygamous marriage can be defined as a voluntary union for life of a man with one or more wives (Cottrell, 2013). Its essential characteristic is the ability of the man to take as many women as he wants. The mere fact that he has at one time only one woman does not affect the character of the marriage as long as the capacity to take more women is preserved. Generally, there is no limit to the number of wives a husband could take under the polygamous system. It always depends on its affluence .
 Marriage is an institution that represents all the behaviors, norms, roles, expectations and values associated with the legal union of a person or a union of persons who are most often of the opposite sex involving a man and a woman.  This is one of the major events in life that marks the transition to mature adult life and represents a lifelong commitment of two people to each other.
As a system, marriage is carrying out, following a series of colossal procedures as practiced and understood by the cultures of the parties concerned. Different communities recognize patterns and types of marriages according to their cultural / social worldview . Nigeria, as part of the wider African society, has been generally characterized by arranged marriages, polygamous marriages and others. Old tribal traditions disappear and more Nigerians adopt Western marriage concepts . This trend has led to an unprecedented increase in customary law marriage in Nigeria. Boateng, cited in Ardayfio-Schandorf, observed that family origins and ethnic origins that were of considerable importance in the traditional practice of marriage were replaced by love and affection between partners .
1.2 Statement of the Problem
 The dynamics of culture and human relations allowed researchers to observe many influences, manifestations and occurrences in marriage within Nigerian society. These manifestations and occurrences have had a significant impact on the stability of marriage in modern Nigerian society. A recent observation of people’s attitudes towards marriages in the country has revealed the alarming negative effect of these events (Animasahun and Fatile 2011). The factors that militate against the quality of marriage in Nigerian society of the 21st century have been the subject of discussions between Nigerian social psychologists, religious authorities, behavioral psychologists, sociologists and anthropologists
However, substantial research has reinforced cultural differences as a source of instability, conflict or dissatisfaction for couples , rather than an opportunity for transformation. Many conclude that intercultural couples are confronted with higher levels of marital challenges; Are more prone to failure; and are rooted in conflicts related to dormant allegiances of worldview, family structures and models of communication . This work explores the dynamics that promote the legal effects of customary marriage in marriages in Nigeria to determine the prospects for these marriages in the 21st century. It also shows that intercultural marriages offer opportunities for a positive transformation of the negative tendency of marriages rather than wid
