Yes, you are
As long as you were legally divorced from your first two spouses you are free to marry again in the United States. Remember that you can only be married to one person at a time. You cannot remarry until that marriage has been dissolved legally.
I do not think a lesbian couple can get legally divorced as m any states do not recognise even in Iowa.
No. But you can be married to only one person at a time.
No, it would be called 'bigamy' and it's a crime. In the United States you can only be married to one person at a time. Your second marriage would be invalid.
If you get re-married before you have legally been divorced then you are committing bigamy. A crime in many countries and states.
no, you can get married living in most countries and states
Yes.
the Full Faith and Credit Clause
All States are not the same. In some States it is 'The divorce will become final thirty (30) days after the final order is entered. During that thirty (30) day period, you are divorced; however, since the decree is not final, you should not remarry.' If the above applies to you then you aren't married and living common law. If it does not apply then you were considered divorced, then remarried and are now legally married.
You're never legally divorced until you file. Meaning you can live seperately for years in different states with no contact. But until you file that paperwork that person is still your spouse.
No. A legal separation must be obtained through a court process and legal separations are not available in some jurisdictions. In the United States a legal marriage must be ended by a legal divorce.You are still legally married until you obtain a divorce in the United States. Your spouse will be able to make decisions for you if you are medically incapacitated, will have the right to plan your funeral, and if you die your spouse will inherit your property and be the first person considered to be appointed the administrator of your estate.
The states have reciprocity as regards marriage (each respects the others' laws) unless, of course, you are gay.
