When engaged, the bride price is also given to the man's wife. The bride price is somewhat uncertain. Anything with good conditions is ok, and it doesn't matter if the conditions are completely bad. It is absolutely unreasonable not to give it. The bride price only needs the man to give it to the woman, and the woman does not need to give it to the man.
When engaged, both parties have to pay a change fee. That is, money called mom and dad. Give it to both men and women. Just how much, and two thousand. There's more. Depends on economic conditions.
