When Not To Combine Policies
Though you're now joined in holy matrimony, there are some cases in which it just doesn't make sense to bring that partnership to your car insurance. Esurance warns that if one of you has a truly poor driving record, separate policies could end up costing you less.
"Combining a low-risk driver's policy with a high-risk driver's will likely increase the low-risk driver's car insurance rates," according to Esurance. There's also the chance that your insurance company simply won't insure your accident-prone partner, no matter the cost. "If one spouse has more than three accidents, your insurance carrier may not accept the spouse," Lovett says.
Here's where the really bad news comes in: Even if you don't combine policies, simply living under the same roof as a high-risk driver could have a negative impact on your car insurance rates.
Esurance explains why: "Because insurance companies consider the driving histories of all family members living within the same household when underwriting policies, having a high-risk driver under your roof makes you riskier by association." Car insurance follows the car, so your policy would have to cover the damage if your spouse caused an accident on an errand in your vehicle, for example.
There may be a way around this, though. "In most states, you are required to list all drivers in your household on your policy," Lovett says. "However, you can 'defer' someone, meaning they have their own insurance policy."
Also called a driver exclusion, this is an easy way to keep insurance costs low, even if your spouse is high risk. Keep in mind that exclusion truly means excluded: If your spouse borrows your vehicle and gets into an accident, you're responsible for any and all damages.
