marriage license???

Brittany • Mommy to a wonderful 12yr old boy, 9yr old boy 7yr old girl 6yr old girl and 3yr old girl. Due March 11th 2023 with a boy.
I'm just wondering, if you stand in Church before God, family and friends, say your vows and make a promise to God but don't sign the legal document (marriage license) are you still married in Gods eyes?
