Okay LexiBride this is what I have found out. I am going to quote directly from the Marriage Bureau/County Clerk office website (here is the link City Clerk's Office - Marriage FAQ)
Even though this is for NYC, I believe that this will be statewide.
. Can I use a Marriage License obtained at one of your offices in another state?
A. No. A Marriage License issued in New York City may not be used outside of New York State. Please note that if you marry outside of New York State, your marriage record will be filed in that jurisdiction.

Q. Can I register my Marriage Record from another jurisdiction with your offices?
A. No. We do not register marriages performed in jurisdictions outside of New York City in our offices. We only maintain marriage records where the Marriage License was obtained in one of our offices. While some other countries require their residents to register any marriage performed elsewhere in their local registry, New York City does not.
What does it all mean? (sorry to get a bit legalese on you but I will keep it simple) You see the state that you get married in is very important when it comes to domicile/residency issues and also divorce proceedings. Most states have rules about how long you can be living there before getting a divorce, etc. Getting married in another state and not having it registered in NYS doesn't make the marriage null and void, it just simply means that you were not married in NYS but your marriage license will be recognized by the state (not registered but recognized as you and your spouse being married) as long as the license was valid where and when issued.
I hope this helps. Sorry it is long. If it isn't too clear please feel free to PM me.
