A more thorough explanation:

Concealment is when someone intentionally or unintentionally hides important information that should be shared in a contract. This can happen when someone lies or doesn't tell the whole truth about something that could affect the agreement. If the information is important and the other party couldn't have known about it, the contract might be cancelled.

• Active concealment: When someone doesn't share important information even though they have a duty to do so.
• Fraudulent concealment: When someone hides information on purpose to trick or cheat the other party.
• Passive concealment: When someone doesn't say anything even though they should have shared important information.

Let's say you're selling a car to someone. You know that the car has a problem with the brakes, but you don't tell the buyer. This is an example of active concealment because you had a duty to disclose the problem but didn't.

Another example is if you're selling a house and you know that there's a leak in the roof, but you don't tell the buyer. This is an example of fraudulent concealment because you're intentionally hiding information to deceive the buyer.

Finally, let's say you're selling a used phone online. You know that the battery life is very short, but you don't mention it in the listing. This is an example of passive concealment because you should have disclosed the information but didn't say anything.

These examples show how concealment can happen in different situations and how it can affect contracts. It's important to be honest and share all relevant information when making agreements with others.
