Okay kiddo, let me tell you a story about a man named Joe. Joe found a bag of money on the street and thought it was his lucky day! He decides to keep the money and spend it on things he wants.
But wait, someone comes along and says that the money actually belongs to them and Joe has to give it back. Joe says, "But I thought the money was mine! I had a claim of right to it."
The claim of right doctrine means that if someone honestly believes that they have a right to something, even if they are wrong, they may not be charged with a crime. Basically, if Joe believed that the money was his and had no intention of stealing it, he might not be in trouble for keeping it.
But remember, just having a claim of right does not automatically make it true. The court will have to decide who the rightful owner of the money is.
In conclusion, claim of right doctrine means that if someone honestly believes that they have a right to something, they may not be charged with a crime even if they are wrong. But, the court will still have to decide who is actually right.
