What is unjust enrichment. Or at least a simplified version. I can provide the defintion on the bottom but want it to be explained as simlpe as possible> Thankyou so much.

defintion: Unjust enrichment is a term used to describe a situation wherein one party benefits at the other party's expense, in a situation the law considers to be unjust. Unjust enrichment is usually used to describe benefits that are received either accidentally or in error, but which have not been earned, and ethically should not be kept. Unjust enrichment is typically considered to be unfair, and those who are declared unjustly enriched are required by law to pay the other party restitution. To explore this concept, consider the following unjust enrichment definition.

What is Unjust Enrichment

When someone is said to have been "unjustly enriched," this means that he has benefitted at someone else's expense, due to chance or mistake. In such situations, the law of equity demands that the enriched party make restitution to the person who was injured. Consider the following example of unjust enrichment provided below:

Annie drops her two dogs off at the groomer to have both dogs clipped and cleaned. The groomer is able to clean and clip the first dog, but becomes too busy to get to the other dog before the end of the workday. Here, the groomer would be unjustly enriched if it received payment for both dogs, but only cleaned and clipped the one. Similarly, Annie would be unjustly enriched if she only paid for the one dog but received services for both.

The groomer may have breached the agreement that was reached with Annie, but the groomer is still entitled to keep the payment it received for clipping and cleaning the first dog. If Annie was to take the groomer to small claims court for the payment she made toward the second dog, she would be entitled to restitution - that is, her money back - for paying for a service she never actually received.

Examples of unjust enrichment are typically found in breach of contract lawsuits. Like the situation presented above, unjust enrichment usually results in situations where one party receives service or goods that is considered to be unfair. Other cases that may involve unjust enrichment are those that involve personal injuries or criminal violations.
