First,
You have finally met that Miss right and is time to follow her to her place. Then that comes what we call "knocking at the door" (iku aka n'uzo).
Is the first visit to declare your intention to the family. Prior to that none of her family member knows you.
The picture below is exactly how "knocking at the door" is performed as regards to the requirements.

The second visit is the bride price payment which is usually among the kindred members and you are also expected to provide the necessary requirements.
Note that bride price payment or dowry payment is not the same as the traditional marriage, although most often it can happen same day but different requirements.
For my kindred people, below is their requirement for bride price or dowry payment.
