From: Rabbi Moshe Sofer
To: Rabbi Meir
The Chasam Sofer rules against compelling an apostate husband to divorce his wife, even through physical coercion, citing the gravity of the eishes ish prohibition. He endorses instead the practical approach of petitioning secular authorities to enforce the husband's financial obligations, which will naturally lead him to agree to a divorce voluntarily.
