If one has a dispute that needs to be settled in Beis Din – is there a fee for Beis Din. If yes, is the meritorious party allowed to claim these expenses from the other party.
Most batei din charge a small fee for opening a case. The expense is not great, and the meritorious party does not have the right to claim it back from the other party.
Sources: Shulchan Aruch, Choshen Mishpat 14:5. The exception to the rule is where the other party was a sarvan, meaning somebody who refused to come to beis din, and expenses were incurred in dragging him to beis din.
