Roommates share all kinds of things, like living space, toothpaste, even Thai takeout leftovers. Did you know that you can share an insurance policy?

It's pretty easy: For around 50 cents a day, a basic renter’s insurance policy can be a financial lifesaver in case of fire or theft, as well as at least a dozen other situations that may happen to you and/or your roommate, like power surges that zap your appliances, accidental floods, and even lost luggage.

Unlike immediate family members who live together, roommates aren't automatically covered unless they’re actually listed on a policy, says apartment insurance broker Jeff Schneider of Gotham Brokerage.

Here’s the lowdown on what you need to know about renters' insurance for roommates:

1) A roommate does not have to be on the lease to be added to the policy.

2) A maximum of two unrelated people can be on a single policy, so additional roommates will need to buy a separate policy.

3) There’s no extra charge to add a roommate, and it won’t change your premium either. You may want to increase your coverage if you have a lot of valuables, but you’ll still probably pay less than you would alone since you get to split the cost.

4) Theft by a roommate—or intentional damage—is not covered by insurance, whether they’re on the policy or not. (Which is why you should only share renter's insurance with someone you know fairly well—not someone you just met.)

5) You are sharing the coverage with your roommate. All claim checks will be payable to both of you, and either person can change or cancel the policy. So sharing coverage is something to do with someone you know and trust.
