There are only two types of marriages recognised in Nigeria;
1.Marriage under the Act (Matrimonial Causes Act and Marriage Act),
2. Marriage not under the Act (Marriage under Islamic Law and Marriage Under Customary Law).
The first is monogamous in nature while the latter is subject to its tradition and uncodified rules.
For intending couples of the christian faith, there is no such thing as “church wedding”. If your church is a “licensed place of worship”, what they conduct there is a “Marriage under the Act”. If your church is not a licensed place of worship and you only conducted a customary marriage without going to the marriage registry, what they would have done in your church may just be a celebration and the blessing of your customary marriage.
If your church is a licensed place of worship, wedding in church and also going to the marriage regisrty are one and the same thing (Marriage Under the Act). Meaning a waste of resources and duplicity of purpose.
