But since the large majority of frum Yidden have a chazaka of being Yirei Shamayim, the last type of unfortunate situation should be a distinct minority of divorces. But nevertheless an option in the toolbox of Butei Dinim, should it be necessary.
The limited available data I’ve seen and my own anecdotal experience do not support the assertion that the vast majority of divorces in the frum tzibur involve two parties with equal bargaining power and resources willingly submitting themselves to a final adjudication by a beis din and subsequently willing to submit the psak din to a secular court in a settlement context. Nor have you supported your assertion that in 50 percent of cases, it is the woman who is making “unreasonable” demands of the husband or otherwise seeking use the secular courts to “destroy” their him. The halacha is what it is and is not the issue being debated.
