No need to keep them at all unless you are expecting a claim.
Any document that could be admitted as "evidence" in a court of law should be kept for at least seven (7) years. Keeping those policies, even though the date of coverage has expired, is you proof positive that you indeed had proper insurance coverage during the aforementioned time period.
No, you should not keep expired passports for any reason. It is recommended to destroy them to prevent misuse or identity theft.
You should not use an expired passport for travel. Instead, you can keep it as a form of identification or return it to the government for disposal.
Your agent should have a copy of your policy, as does the underwriting department of the insurance company, and you should have a copy of the policy. I recommend making and keeping multiple copies of all policies. Possibly keep one copy of each at your home and other copies off premises. You have a proof of insurance card for the car. There is no good reason to keep a copy there. You may want to store at home with your other policies and other copies of policies at a safety deposit box in case a storm or fire affects the home.
Money, jewelry, will, gun, insurance policies
No, you should not keep your expired passport as a memento or for any other purposes. It is recommended to return it to the issuing authority for proper disposal.
Participating policies are life insurance policies that pay dividends, where dividends enable you (the policyholders) to participate in the insurance company's favorable experiences (such as higher than expected investment returns or lower than expected operation.) Non-participating policies, historically belong to the stock companies where the company's favorable expenses were paid to the stock holders, rather than the people who own policies within the insurance company. Even though the participating policies were mostly offered by the the mutual insurance companies, due to consumer appeals to receive dividends, stock companies also started offering participating policies. You should keep in mind that the dividends are not guaranteed and it is illegal for insurance agents to make future projections (where the participating policies also tend to have little higher premiums.)
If one has a poor driving record, one will be required to purchase a high-risk insurance policy. These policies are very costly, but they will be worth the value to keep your car on the road.
An expired passport can be used when applying for a new one.
as long as you want if other people think otherwise just sew
You should keep the records for a minimum of 5 years.
CURE Insurance was founded in New Jersey in the 1980's when larger insurance companies were not willing to write many car insurance policies. They are a non-profit agency, and this helps them keep rates low.
