Hi, Anonymous —

Marriage laws vary from state to state, assuming you live in the United States.

I can only speak for Massachusetts. In Massachusetts, all marriages require a license, irrespective of whether it is a Church or civil ceremony.

I would imagine other states in the Union have similar requirements. I suggest you check the local laws as this is, not a doctrinal question but, a legal one.

In general, you do.

It is possible to get what is called a secret marriage, but the restrictions are exceedingly strict.
It is not intended for those who wish to defraud pensions and insurance companies and so forth.
