A more thorough explanation:

Clear title means that there are no disputes or claims about who owns a property. Sometimes, there can be doubts or disagreements about ownership because of things like liens or other issues. To make sure a property has clear title, people can do a title search to look for any problems in the public land records. If there are problems, it's called a "cloud on the title."

Having clear title is important for anyone who wants to sell their property because buyers might not want to buy a property with a clouded title. Some states have laws that help clear up title issues that go back a long time. In most states, if someone has been living on a property for a long time without anyone else claiming it, they can claim ownership through something called "adverse possession."

For example, if someone has been living in a house for 20 years and no one else has said it belongs to them, that person might be able to claim ownership through adverse possession. If there is a dispute about who owns a property, someone can go to court to try to "quiet title" and clear up the issue.
