Everyone knows the agunah problem, a husband refuses to give a get and the wife is stuck and cannot remarry. I want to understand what the halacha actually has in its hands.

1. What is the Torah source for the get itself, and what does it accomplish? Devarim 24:1 talks about a sefer keritut. Is divorce a mitzvah, a permission, or just a mechanism, and does the Torah picture the whole thing as the husband’s choice?

2. When a husband refuses, what can a beis din actually do? The Rambam in Hilchos Gerushin (2:20) says that when the din is that he must divorce her, they force him until he says I want to. Which cases does that apply to, and what happened to that power? Shulchan Aruch Even Haezer 154 brings the cases of kefiyah, so why do batei din today almost never use it?

3. What are the real tools now? Seruv, cherem, public pressure, the prenup. Do any of them have halachic teeth or are they just social pressure?

4. The gemara in Gittin (33a) and Yevamos (90b) says kol hamekadesh al daas rabbanan mekadesh, that chazal can annul a kiddushin. When does hafkaas kiddushin or mekach taut actually apply, and could it free an agunah today? Why is it almost never used?

5. What is Rabbi Abadi’s position on all of this? Is the agunah crisis a halachic problem with no answer, or a problem where the answers exist and the poskim are afraid to use them?
