I truly do not understand why this isn't being handled NOW by nosha's public liability insurance company - there isn't an excess on a PL policy, we're not talking car insurance here. If the woman decides to take it further because she can't get agreement from your husband's company, then you're going to get legal costs on top of this. This is exactly what your PL insurance is FOR - if you give her a copy of the certificate, as you must, it's pretty obvious that she's going to report it to them and make a claim. It'll be better for your company if you get there first and report the incident before she does, otherwise they will have to come to you anyway a) for corroboration and b) ask why they've not been notified - you have a duty under the policy to report to them if you think that a claim will arise.
