Witnesses testified that Madame H.T. insulted her husband’s co-wife and mother in law. The Appeal Court granted divorce to Monsieur Y.K. on the sole basis that by insulting his mother his first wife had harmed his husband honor and dignity and made marital life impossible. However, quarrels between co-wives do not characterize a serious insult in a polygamous marriage. Moreover, by asking for divorce from the first wife only, the husband committed a serious injustice and violated his duty of impartiality with his wives. Additionally, insults directed at the husband’s mother do not constitute a legal basis for divorce, according to the Code des Mariages et Tutelles (Code of Marriage and Tutelage). Indeed, the Code only considers insults directly addressed at the husband as a basis for divorce. The Court held that such insults were not proved in this case and could neither be inferred from the behavior of Madame H.T. with her husband’s co-wife and mother in law, nor from her confession of having insulted her husband’s co-wife.
