Ex factis jus oritur

Okay kiddo, ex factis jus oritur is a Latin phrase that means "from the facts, the law arises." This means that the law is based on the facts of a situation.

Let's say you have a toy that you really like and someone takes it without asking. The fact is that the toy was taken without your permission. The law says that it's wrong to take something that doesn't belong to you, so you have the right to ask for your toy back.

Another example is if someone hits you and you get hurt. The fact is that you were hurt by someone. The law says that it's not okay for someone to hurt you, so the person who hit you might have to pay for any medical bills or other damages they caused.

Basically, ex factis jus oritur means that the law is based on what actually happened in a situation. It's kind of like how a puzzle needs all the right pieces to fit together perfectly – the facts and the law need to match up for justice to be served.
