Something I learned firsthand last year when I married my Senegalese husband.

There are three choices: monogamy, limited polygamy (up to 3 wives), or full polygamy (up to 4 wives). If no option is explicitly selected, polygamy is the legal default. Interestingly, once monogamy or limited polygamy is chosen, the decision is binding and cannot be changed later to allow more wives.

Fun fact: The current President of Senegal, Bassirou Diomaye Faye, openly has two wives!
