I believe that most if not all states have an adverse possession law.

Yes, and it kind of stinks. The use of the property by a neighbor may have originally been granted by the landowner of the time, but it was never meant to be in perpetuity and certainly not if the later owner didn’t know about it.

Squatters all over the country have used this to steal property.

In CA at least, you have to have being paying the property tax on the portion you were adversely possessing

I think this is a common law holdover but states set the time limits for adverse possession. Unfortunately, I don't know if its by statute or common law but it doesn't apply to government property - the largest property holder in the USA.
