Has a divorce taken place by the father uttering it jokingly, and does a legal ruling result from that with his death, and what is the ruling concerning the children born after that?

A jocular divorce is binding. If one is unsure about the number of divorces, the lesser number is to be considered. Accordingly, it is considered one divorce, and conjugal relations during the waiting period are considered a return (to the marriage). Children are attributed to their father in all cases as long as he believes the marital bond still exists. The mother must complete the waiting period for widowhood.
