Can I get a civil union or get married in a state I do not live in?

That depends. You should obtain a divorce from your existing civil union if you plan to marry someone else in a state where civil unions or same-sex marriages are legal. Most places that permit same-sex marriage also recognize civil unions as legal marriages.

If you marry someone else in a state where same-sex marriages or civil unions are not recognized, then you risk having your marriage voided when crossing certain state lines or nullified should the law in your state change. Your marriage could become void and your civil union return to effect if you do not divorce your civil union partner before marrying someone else.
