What is the policy provision found in property insurance policies that prevents the insured from collecting twice for the same loss is called?

The policy provision that prevents the insured from collecting twice for the same loss in property insurance is called the "coinsurance clause" or "anti-duplication clause." This provision ensures that the insured cannot receive compensation from multiple insurance policies for the same damage or loss, thereby protecting insurers from fraudulent claims. It reinforces the principle of indemnity, which aims to restore the insured to their financial position prior to the loss, without profiting from it.
