  The Autonomy Default Paradigm in Contract Law



                      HANOCH DAGANt & MICHAEL HELLER


You can scribble an agreement on a napkin orhire lawyers to negotiate a hundred-page contract.
Either way, most ofyour contractual obligations will not be in your document. They will be in the
background  rules contract law applies absent your express agreement. Justifying these defaults
is a core task of contract theory; getting them right is a core task of contract law.

This Article introduces the autonomy default paradigm, a conceptually coherent and normatively
attractive account of contract law defaults. We show that defaults are justified to the extent they
enhance  our autonomy, understood as self-determination. They vindicate our autonomy through
two pathways:  (a) empowering  defaults that proactively facilitate people's autonomy and (b)
safeguarding defaults that protect our future selves and ensure relational justice.

Often, the parties to commercial contracts are legally sophisticated players who just want to get
wealthier. There, the welfare-maximizing default is often the autonomy-enhancing one. But for
the vast run of contracts getting jobs, getting married, buying homes, buying stuff-autonomy
defaults may diverge from their efficiency-based counterparts. In these cases, the law often does
and always should optfor autonomy  defaults, even at the price of some efficiency.
