http://en.wikipedia.org/wiki/MishnahI'm afraid I have to admit ignorance to a lot of the Jewish terms and traditions. You lost me in this.
im sure its in the halaka. the modern jews have councils that decide this and aren't governmental but some it can be legal in that manner its calle beth din. its also where one goes to get a divorce. that is based on deutermony 24. a writ of divorce. why would I don't proclaim my marriage to others that is what a license does. need that?
