If you have read prior articles (see here and here as an example), then you know that when it comes to first-party property insurance policies, an insured must comply with post-loss obligations in the policy. Failure to comply with a post-loss obligation gives the insurer the argument that the insured materially breached the policy and, therefore, forfeited rights to coverage. Naturally, this is avoidable by ensuring post-loss obligations are complied with, ideally under the guidance of counsel and qualified public adjusters to ensure your rights are being preserved and maximized.
[W]hen an insurer has alleged, as an affirmative defense to coverage, and thereafter has subsequently established, that an insured has failed to substantially comply with a contractually mandated post-loss obligation, prejudice to the insurer from the insured’s material breach is presumed, and the burden then shifts to the insured to show that any breach of post-loss obligations did not prejudice the insurer.
