Successor state
In micronationalism, a successor state is a state or micronation that is considered, as a matter of international law, to have succeeded a previous state - in other words, that the new state is entitled to be considered, in some way, a continuation of the jurisdiction of the previous state, commonly over the previous state's territory or government. Depending on the political context in which a state becomes a successor to a former state, the new state may have a distinct legal personality or may be entitled to rights or possessing of obligations that were previously held by the state it succeeded.
Examples
Grand Unified Micronational
The Grand Unified Micronational has formal provisions for if a member state is ever legally succeeded by another state, set out in Chapter 2, Article 3, Section 2 of its Charter. In the event that a full member state of the organisation disbands and its law at the time of its disbandment names a state as its legal successor, that successor is entitled, if they claim it within two months, to be a full member of the organisation in its place.
Stabilitas
During its existence, Stabilitas claimed to be the legal successor state to the nation of Burkland. Its Queen had previously created a Burklandi government-in-exile.
