You need to carefully read your written lease agreement with your landlord to see if you contractually agreed to have a renter's policy of insurance with respect to the unit you are renting. If you are, then under the law the landlord is within his rights to seek a copy of the policy you have in that most likely your policy is primary for any damages to the unit the landlord owns and his is secondary.Perhaps the better way to have gone about the task would have been for the landlord to ask you directly for a copy of your insurance policy.
