From FMOTL Wiki
A NOUICOR, sometimes referred to using similar acronyms, stands for a Notice of Understanding and Intent/Claim of Right. It is a formal legal process which allows a right to be exercised avoiding contention in a court. It is a two part remedy which prevents disinterested parties interfering in a parties right. The Notice of Understanding and Intent part sets out the issuers understanding of the law and specifies that it is their intent to claim a specified right. This may be any right to which the issuer is entitled, whether the right be granted, utility to a granted right or simply an inalienable right. Like most notices, the NOUI part of the remedy has a time limit for anyone reading it to correspond. If there is no correspondence disputing the notice, it is accepted in law to be the truth.
Usually a NOUI will be notarised by a notary public, but its subscription being witnessed by three good people will suffice to the same effect.
Based on the Notice of Understanding and Intent that is sent to all potentially interested parties, a Claim of Right is then made, usually sent to the same potentially interested parties, but not neccessarily so as it merely puts in black and white that a claim has been made and it is sufficient to simply have its subscription witnessed.
