Now if you get married in Peru, does that mean that it'll automatically show up on your records back home? No, it won't. If you get married in Peru and then go home and check if you have a marriage record, you won't. It'll still show that you're single.
So what do you do? It depends on where you're from. If you're from the US, they usually don't ask for official translations or apostillisations. Personally, I would still get my Peruvian documents notarised, apostillised, and translated. Here's a guide on how to use Peruvian documents abroad.
Update August 2014: some counties in the US aren't allowing you to record foreign marriages or divorces anymore. Contact your county clerk for more info.
In the US you cannot register a foreign marriage. It's impossible. What exactly does that mean for people who get married abroad? It's simple. In the US you're only allowed to register a marriage that takes place on US soil. If you get married abroad all you have to do is bring your foreign marriage cert and a translated copy (Doesn't have to be official. You can translate it, a friend, Google, etc) to the county clerk's office. Then the record it and it'll show up on your record.
What does it mean? It's just semantics. You register marriages that take place on US soil and you record marriages that take place on foreign soil. The end result is the same: you'll show up as being married. If you get divorced, you follow the same procedure.
One tip to remember is that speaking Spanish will help you greatly. You'll be treated differently than if you speak English all the time, it'll help you assimilate to the culture, and you'll be able to communicate easier.
