Is it possible to acquire a new General Liability Insurance policy for a Small Business which will cover work that your firm has already recently completed without coverage? 
A liability claim has a time that it is discovered and the time that it occurs . There are two basic forms of liability coverage , occurrence and claims-made . If the claim has not been initiated , some insurer might assume the risk on a claims-made basis . It is unlikely they will do that if they suspect a claim is coming . On the very esoteric side , though , there are companies that insure after a known loss . These policies are written for tax purposes .
