A more thorough explanation:

In property law, peaceable possession refers to the type of possession of a piece of land that is held without any adverse claims made by another party to recover the property. This means that the person in possession of the land is not being challenged by anyone else.

For example, if John owns a piece of land and has been using it for farming for several years without any objections from his neighbors, he has peaceable possession of the land. However, if his neighbor, Jane, suddenly claims that the land belongs to her and tries to take it away from John, his peaceable possession becomes disputed.

Some states require a plaintiff to have peaceable possession of a piece of land in order to bring an action to quiet title. This means that the plaintiff must be able to prove that they have been in peaceful possession of the land without any challenges from others.

It's important to note that simply denying someone else's right to possess a piece of land does not automatically destroy their peaceable possession. The other party must take action to indicate that they claim to be in possession themselves.

For example, if John's neighbor, Jane, tells him that she thinks the land belongs to her, but doesn't take any action to try to take it away from him, John's peaceable possession remains intact. However, if Jane starts building a fence around the land and tells John that he can no longer use it, his peaceable possession becomes disputed.
