Looking for an SF story... not a YASID

[dsrtao]

Is there a story or novel in which, upon attaining an age of majority, the new adults must either explicitly sign on to a formal social contract or be exiled?

It seems like the sort of thing that should have been done, but I can't think of any examples. (Several rite-of-passage novels come to mind, of course, but that's different.) It seems like obvious Prometheus Award bait...

Not quite what I'm looking for:

• Starship Troopers (service for citizenship is not mandatory, not age-linked, they won't throw you out)


• Coventry (participation in society is assumed, exile is an option for felons)


• Those Who Walk Away From Omelas (almost right, but there's no explicit social contract, just a utopia powered by evil)


• Divergent (not sure, but appears to be about cliques and conformity rather than governing rules of society)


• anything where you have to lose or win citizenship rights rather than just agreeing with them

There was some discussion that I recall in A Young Ladies Illustrated Primer about clades and social compacts, but I am not recalling if there was a discussion about when youth reach majority.
