Is institutional arbitration in Israel significantly more expensive than ad hoc?

Yes, but the gap is often smaller than it appears. ICCA charges a registration fee of NIS 2,000-6,000 plus an administrative fee of roughly 0.5-1.5% for claims under NIS 5 million. For disputes under NIS 300,000, ad hoc usually saves money; above NIS 1 million, the institutional efficiency often pays for itself. If an ad hoc case suffers procedural delays requiring court applications, each costing NIS 5,000-12,000 in legal fees, the total cost can exceed the institutional option.
