Talk to a lawyer: you can probably get the marriage annulled.
I'm not a lawyer, but I think it is.
US laws take precedence, therefore if the couple were legally married in the US and legally divorced in the US, then the divorce is valid. If the couple lived together as a couple (engaging in a sexual relationship, sharing mutual finances, etc.) at the time the divorce was pending then the divorce is not valid.
In order for a marriage to be valid, the license must be signed by both parties willingly. If no license was signed, there was no marriage in the first place.
no
If you never applied for and got a marriage license, but got married anyway, then no, the marriage is not valid. And any minister, priest, etc., who performed the ceremony without you having a valid license can get in trouble, although I don't know what the penalty for that would be.
Georgia will recognize a certificate of marriage from Jamaica. The license will not be valid in the US.
If the first marriage was never legally terminated (though divorce or annulment), the first marriage is still valid and the second marriage is invalid.
Yes, a marriage in England is valid in the United States.
No, it would not be valid. You really should get the license.
Yes it is valid proof of marriage. The joint agreement is signed by both in the presence of winesses.
Here the most important thing here is that you do posses a valid marriage certificate, even if there was no marriage ceremony whatsoever . It will very well be valid.
