Possession is nine-tenths of the law is an expression meaning that ownership is easier to maintain if one has possession of something, and much more difficult to enforce if one does not. The expression is also stated as "possession is nine points of the law", which is credited as derived from the Scottish expression "possession is eleven points in the law, and they say there are but twelve".[1]
This principle can be restated as: "in a property dispute (whether real or personal), in the absence of clear and compelling testimony or documentation to the contrary, the person in actual possession of the property is presumed to be the rightful owner. The shirt or blouse you are currently wearing is presumed to be yours, unless someone can prove that it is not"
