I am writing a paper about fair division. When we divide, say, a piece of land among us, the division may be fair in the time of division, but may seem unfair at a later time, for example, if oil is found in one of the land-plots.
I am looking for a single word (a noun) that emphasizes the fact that a division is fair only in a specific point in time. Using Google translate, I found "momentariness", "instantaneity", "temporariness", but, I don't which of these words, if any, fits the context.
An example paragraph: "Our third assumption is _____________. This means that, when we check the fairness of a certain division procedure, we only check that the division is fair at the time it is made. We do not require that it remains fair forever."

If an example sentence were provided, looking for an answer would be easier, but I like the word "transience". The adjective 'transient' related to it may be used in a construction like "transient nature of", the word nature being the core noun there:
There are synonyms for transience like ephemerality, fugacity, but they belong more to the belles-lettres style of writing.
Related words: unreliability, unpredictability, inconstancy, impermanence. These may be 'adjectivized' and used in constructions like "unreliable nature/character of...".
