But the women who've lived with someone for 6 years and start calling the guy their "husband" even though there has been no ceremony...I don't count that. I wouldn't SAY so, of course, but I don't consider living together the same thing as married.
But in Rhode Island (as well as a few other States), they WOULD be legally married in that case (assuming they are both free to marry). Just as married as someone who had procured a license and had the most lavish church wedding possible.
Common law marriage in the US is different than in Canada, apparently. Here, there are slight differences in the laws of the handful of States which still allow the formation of common-law marriages, but the essentials are generally:
1. The couple is legally free to marry. Meaning no one can be married to anyone else, they must be of age, and they must be of sound mind. Also, they must meet the requirements of that particular State in which the union is formed. In other words, if gay marriage is not allowed in that State, two men cannot form a common-law marriage there.
2. They must hold themselves out to the community as married. Legally, all this means is that they tell everyone they are married and refer to each other as husband and wife. They would not have to share a surname, pool finances, etc...but they SHOULD claim that they are married on all forms including tax returns and insurance paperwork. You can't pick and choose when to be married and when to be single. You're either married or you're not. If a couple tells Great Aunt Mary they are married because she is ultra-religious and will freak out that they're living together, but doesn't say they're married to anyone else, then they're not married.
3. Evidence may be required in court if the marriage is contested...generally things like cohabitation, proof of consummation (having a biological child together helps, lol), wearing wedding rings, possibly sharing a surname, pooling finances/owning property as husband and wife, and habitually and continually acting as a married couple. None of these is definitive, but taken together they may form a clear picture of the parties' intentions. Of course, if both parties admit they intended to be married all along, there is little question.
4. The seven years thing (that you are automatically married at common-law after 7 years of cohabitation--which most people believe to be true) is a falsehood. You can't just live with someone for seven years and suddenly be married if no marriage was ever intended. You can live with someone for 50 years if you want, pool all your resources, have ten kids, and still not be married, if that's what you desire!
Usually this stuff only comes up when someone dies or the couple divorces (yes, you have to file for a legal divorce if you were married under common-law), or when insurance companies deny benefits to the spouse.
I have a lot of other fascinating facts about common-law marriage to share, but it's very late (THANK YOU, RED SOX!!!!!!!!!!!!

) so I'll have to save those for tomorrow (errrrr, later today).
