Health,
you said,
“B’D doesn’t force anybody to come to them. They come on their own free will!”
Right. They just say “If you ever want to be able to marry anyone else and have children that aren’t Mamzerim you have to arbitrate everything with us”.
you said,
“That’s your mistake. These aren’t separate services. They are all part & parcel of the divorce.”
You yourself admitted that if the B”D wants they could choose not to Arbitrate custody and assets, so of course they are separate services.
