Rabbi Aryeh Klapper attests: "A wide variety of prenuptial agreements have been proposed. Each had its halakhic proponents and detractors, but for better or worse none gained the kind of widespread support necessary for effectiveness until seven years ago. At that time, a mechanism originally suggested by Rabbi J. David Bleich and developed by Rabbi Mordekhai Willig gained overwhelming halakhic approval throughout the Orthodox rabbinate. Rabbinical organizations such as the RCA and Young Israel, and lay organizations such as the Orthodox Caucus and the Wedding Resource Center, then began the continuing effort to make signing this agreement universal practice. This effort is meeting with growing success. The number of couples signing the agreements is growing dramatically, as is the number of rabbis strongly recommending it, or even refusing to officiate without it, in prenuptial meetings."
