The Kids Live at Both Houses: What Happens to Auto Insurance?

Mom and Dad are divorced. Their teenager spends one week at Mom’s house and one week at Dad’s. The teen drives Mom’s car sometimes, Dad’s car sometimes, and there can even be a vehicle everybody calls “the kid’s car.”

The insurance question is not as simple as choosing which parent gets to list the teenager.

Start with the real living arrangement

Tell both insurance agents where the teen actually lives and how the time is split. A custody order can describe the legal arrangement, but the insurer still needs the practical facts about the household and the driving.

Which vehicles does the teen drive?

List the cars the teenager drives at each home and how regularly they use them. If one vehicle is treated as the teen’s primary car, say where that vehicle is usually kept overnight.

Garaging matters

Where a vehicle is primarily kept is part of the risk picture. If the so-called kid’s car spends most nights at one address, both households should not make different assumptions about where it lives.

Michigan parents have a specific disclosure responsibility

Michigan DIFS tells parents to notify their insurer when a teenager becomes a licensed driver. Failing to disclose household drivers can create premium problems and can affect a claim. Divorce does not erase that responsibility because the teenager has two addresses.

Do both insurers have to list the teen the same way?

No universal setup applies to every company. Carrier rules differ. One company can handle the driver differently from another based on the household, vehicles, and use. That is why both agents need the same accurate facts.

What changes later?

Tell the agents when the custody schedule changes, the teen starts driving a different car regularly, a vehicle changes its primary address, or the teen gets a vehicle of their own.

What to send both agents

• The approximate time split between homes

• The vehicles the teen drives at each home

• Where each vehicle is primarily kept

• Whether one vehicle is treated as the teen’s regular car

• Any upcoming change in the living or driving arrangement

Do not decide privately which parent’s insurance “gets the kid.” Tell both agents what is actually happening and let each carrier determine how the driver needs to be handled.
