This article examines the ways in which the negotiation framework—i.e., the legal guarantees, information management mechanism, and degree of inclusivity in peace negotiations—shapes the likelihood of concluding a peace agreement. Codifying the peace negotiations in law, publicizing information about the content of negotiations, and including mediators and civil society actors in peace talks is likely to increase a government's short‐term costs. However, doing so alleviates the adversaries' information asymmetry and commitment problems, sets guidelines to insure the process against exogenous shocks, and increases the number of actors taking part in conflict management. Comparing the recent peace negotiations to end intrastate wars in Colombia and Turkey, this article argues that a legalized, public, and inclusive framework made a peace agreement possible in Colombia, while the lack of such a framework caused Turkey's peace talks to fail.
