Which of the following would evidence ownership in a participating health insurance contract?

Ownership in a participating health insurance contract is evidenced primarily by policy ownership. This indicates that an individual or entity holds the rights and responsibilities associated with the insurance policy, including the ability to make changes to the policy, receive dividends, or transfer ownership. The owner is recognized as the legal entity entitled to access the benefits of the contract and make decisions regarding it.

In the context of a participating health insurance policy, ownership is critical because these policies allow the policyholder to participate in the financial successes of the insurer, often in the form of dividends that can be used to reduce premiums or increase coverage. Therefore, being the policy owner is what provides the holder with tangible benefits and authority over the contract.

The other options may involve aspects of a health insurance contract but do not convey the same legal rights or ownership. Employer contributions relate to payments made by an employer for an employee's policy but do not confer ownership rights. Nominee designation involves naming someone to receive benefits but does not establish ownership of the policy. Similarly, spousal rights can refer to coverage or benefits available to a spouse, but they also do not equate to ownership of the policy itself.
