Question - are there any statistics for percentage of people in Nigeria who have a traditional weddings, vs. church weddings, and registry weddings? What do most people opt for?

How is divorce regarded in Nigeria? What divorce proceedings are necessary for a church wedding or traditional wedding, since they are not recognized fully under the law? For a Traditional wedding would it be enough to simply return the dowry or is there a divorce proceeding involved?

I have heard that church weddings are the least "recognized" but being that you are taking a vow before God I would think that a church wedding would carry more weight than a court/registry wedding, I guess depending on how religious you are?
