Perpetuity – this term means something that is permanent and not ending quickly. The term is used in the Contract Law in many jurisdictions, where details the deadlines, implemented in contracts, for making payments that continue indefinitely – it sets the date for making payment and deadlines for it. Another example is in the Real estate Law, where a perpetual easement is an easement which lasts permanently, usually through the whole lifetime of the easement holder. This may be the right of occupation of premises, established in favor of a concrete person – once set up, he holds it officially for their whole life and can defend it against any third parties, and with their death it is terminated. Another example is the “perpetual statute”, which is each act of legislation that is stable in time and is expected to take force for long period of time within the concrete society. For example, Codes are example of perpetual statutes.
