A more thorough explanation:

A possessory claim is a title to public land held by a claimant who has filed a declaratory statement but has not paid for the land. This means that the person has a claim to the land, but they do not yet own it because they have not paid for it.

For example, if someone files a claim for a piece of public land, they may have the right to use and possess the land, but they do not own it until they pay for it.

It is important to note that a possessory claim is different from ownership. The person with the possessory claim has the right to use and possess the land, but they do not have all the rights of an owner.
