To those who writing about: “people getting Jewishly married and NOT GETTING legally married”
Be advised that in most American states, having a marriage ceremony is sufficient to be married under the laws of the state. While some states require a license for the marriage to be recognized, most states do not (the license is a revenue measure, and the clergy performing the marriage may have to pay a fine – but the marriage is valid under state law).
If someone has a kesubah and kiddushing and huppah (and arguably merely bi’ah, at least in states that allow common law marriage) – they are married meaning they are required to file joint tax returns, are liable for each other’s debts, and the father has no way out of supporting the family, etc. – and they can be prosecuted for bigamy if they have a “get” without a civil divorce, which means a subsequent marriage will be void under state law.
