Legal Question in Family Law in California

Re: Getting married in Canada. Is it Valid in the US.

Yes, it's exactly the same as if you'd been married here. Before you leave, however, call the local officials and find out what documents you'll need in order to get married in Canada. You may need blood tests, doctors' certificates, proof of any prior divorces, your birth certificat...who knows? There may also be a waiting period between when you apply for a marriage license and when you can get married, so be sure and plan for that. If the red tape is too complicated, you could always have the ceremony there and then make it legal here. Congratulations!
