Hypothetical question

Has anyone dealt with something like this? I'm not sure what my options are sadly.

insurance company denying valid claim. I've been dealing with this for about 14 months now and the situation isn't improving.

I have already consulted briefly with a lawyer but the other party is not cooperating.

What are the risks if I pursue this? What's the likely timeline?

Document all your damages. You'll need specifics for any claim.
