Common Law or Civil Law? Why Knowing the Difference Gave Me Peace of Mind (and Could Give You Peace of Mind Too)

When I pack my suitcase, I don’t just think about sunscreen or snacks for my son. As a lawyer, my mind always travels with one question: “What rules will I be playing by in this country?”

I know it sounds like “office talk,” but I promise you that understanding this is just as important as bringing your passport. There are two main ways of understanding justice in the world, and knowing which one you’re in can save you a lot of headaches.

“Civil Law”: The World of Books (What We Know at Home)

If you’re traveling through Latin America, Spain, France, or most of Europe, you’re in civil law territory.

To put it simply: here, the written word reigns supreme. There’s a law for everything. If you have a problem with a hotel or a rental agreement, a judge will open a huge book (the Civil Code), look up the exact article, and say, “It says right here that this is how it’s done.”

The upside? It’s pretty predictable. The rules are there for anyone to read.
The travel tip? If the contract says something that goes against the written law, that clause is usually worthless. The “Book” protects you.

“Common Law”: The World of Words and History

This is where things get interesting. If you go to the United States, England, Canada, or Australia, the rules change. Welcome to the common law system.

Here, there’s no “Master Book” that lays everything out. Laws rely heavily on what other judges have decided in the past. It’s like saying, “If a judge ruled ten years ago that a tourist was in the wrong in this case, you’re probably in the wrong today, too.”

The bottom line? Contracts are eternal. Have you noticed that in the U.S., when you rent a car, they give you 10 pages of fine print? That’s because in this system, what you sign is sacred. If it’s not on paper, it’s “gone with the wind” or left to a judge’s interpretation.
The travel tip? Read before you sign! In these countries, liability waivers (those “if something happens to me, it’s my fault” papers) are very powerful.

Why am I telling you this? (And how does it help you?)

Here are two real-life examples that happened to me:

On an adventure tour: In a common law country (like the U.S.), if you sign a waiver stating that “you won’t sue if you fall,” it’s very difficult to challenge that later. They take contracts very seriously.

Fines or claims: In a civil law country (like Italy), there’s always a more rigid administrative process and specific forms. Everything is more “bureaucratic,” but based on rules that don’t change overnight.

My advice as a “ Lawyer Mom”

You don’t need to study law before boarding a plane. Just keep this in mind:

If you’re traveling to a common law country: Read everything, ask about every detail, and don’t assume that “the law protects you” if you’ve signed something that says otherwise.
If you’re traveling to a civil law country: Make sure all your documents and receipts are in order, because here, the paperwork is what counts.

Traveling informed doesn’t mean being boring—it means being smart. That way, when the unexpected happens, you won’t be caught off guard, but ready to enjoy what really matters: the destination.
