International litigation is when people or organizations from different countries have a legal dispute and they solve it in a court of law. Imagine you and your best friend have an argument about who gets to play with your favorite toy. You both live in different houses, so you can't just talk to your parents to solve it. Instead, you might go to another grown-up, like a teacher or a judge, to help you decide who's right.
Now, imagine that instead of a toy, you and your friend are arguing about something bigger, like if you should build a new park in your neighborhood. But this time, your friend lives in a different country, like Canada or Japan. If you still can't agree on what to do, you might need to go to court in both countries to figure out the best solution. That's international litigation.
International litigation can be complicated because different countries have different laws and rules. Just like different classrooms might have different rules about when to line up or sit quietly, different countries might have different rules about how to solve legal disputes. This means that lawyers and judges who work on international cases need to be really smart and know a lot about different countries' laws.
In the end, international litigation is all about resolving disagreements between people or organizations from different parts of the world. It's like a grown-up version of you and your friend trying to decide who gets to play with the toy - but with more people involved and more rules to follow!
