What endorsement would Monica and Sam need to fully cover their jewelry collection?

To ensure that Monica and Sam's jewelry collection is fully covered, they would need a Scheduled Personal Property endorsement. This type of endorsement allows policyholders to specifically list high-value items such as jewelry, art, antiques, and other valuable personal property on their homeowners or renters insurance policy. By doing so, each item or collection can be insured for its appraised value, ensuring comprehensive coverage against theft, loss, or damage.

Scheduled Personal Property specifically addresses the limitations of standard homeowners or renters insurance policies, which often have sublimits for personal property like jewelry. Without this endorsement, there might be inadequate coverage in the event of a loss that exceeds these sublimits.

The other options, while relevant in various contexts, do not provide the same level of targeted coverage for high-value items like jewelry. For instance, the Special Form provides broader property coverage but may still impose limits on personal property. Inflation Guard helps to keep the coverage limits in line with inflation but does not directly address the specific itemization of valuables. Personal Property Replacement Cost covers the cost to replace items but still doesn't individually secure high-value possessions like jewelry to the extent required. Thus, the Scheduled Personal Property endorsement is the optimum choice for thorough protection of their jewelry collection.
