Yes, that&#x27;s always a factor. Larger IVBs will tend to err on the side of their reputation in the marketplace (which may also be a factor).<p>One could envisage a (horrible) situation where both parties engage an IVB (a practice common in some areas of engineering) and then they both jointly engage another body to effectively vet their processes and pass that joint 50&#x2F;50 cost into their fees back to you.<p>Or the court appoints one and you agree to share the costs (probably wouldn&#x27;t fly in the US).
