How to Add a Domestic Partner to Home Insurance
Call your insurer or agent to add your partner as a named insured, typically by showing proof of shared residence or ownership.

Named insured vs. additional insured
Ask to be listed as a named insured, not just an additional insured. A named insured has full rights to make claims, change coverage and get payouts for their own belongings. An additional insured, like a landlord, has much narrower protection.
Proof the insurer wants
Most insurers ask for something showing you share the home. That could be both names on the deed or lease, a joint bank statement, or a domestic partnership registration where your state offers one. Check with the insurer before calling, since the list varies.
Effect on your premium
Adding a second adult usually raises the premium somewhat. The policy now covers more personal property, plus another person's liability. The insurer isn't factoring in income. It's counting belongings and risk, so the exact change depends on what your partner owns.
Belongings owned beforehand
Your partner's furniture, electronics and other property brought into the house need to be covered too. Once they're a named insured, personal property coverage on the declarations page should extend to their belongings, not just yours.
Since you're setting this policy up before closing, this is the moment to check it against other insurers rather than adjust it later. A policy that names your partner correctly and covers both of your belongings at one price might cost noticeably more, or less, somewhere else for the same protection. Comparing now costs nothing and the binder your lender needs can still come from whichever policy you pick.
What to do if your partner has their own policy or claim history
If your partner currently rents or owns elsewhere and carries their own homeowners or renters policy, that policy typically ends or gets canceled once they move in and are added to yours. Don't let both run at once out of caution. Paying two premiums for overlapping coverage on the same person's belongings doesn't buy anything extra, and it can confuse things if a claim happens during the overlap.
Your partner's claims history matters once they're named on the policy. Insurers may ask about prior claims for anyone becoming a named insured, not just the original applicant. If your partner filed a claim in the last several years, mention it when you call, since some insurers price this in and others barely weight it. Finding out before the policy is written avoids a surprise at renewal.
If your partner has a poor credit history or a thin credit file, this can affect pricing in most states, since insurers often use credit-based insurance scores as one factor. A few states don't allow this at all. It won't stop them from being added as a named insured, but it's worth asking the insurer directly how they weigh it rather than guessing.
Married couples are usually both listed as named insureds by default when a policy is written, so domestic partners sometimes assume the same happens automatically. It doesn't. The insurer needs to be told to add your partner by name, and the proof of shared residence mentioned earlier is often requested specifically because the two of you aren't married. Taking care of this before closing, rather than after, means the declarations page is correct from day one and your lender's binder reflects the household that's actually moving in.
What if your partner already has a policy, a claim, or credit issues
If your partner currently rents or owns somewhere else, they likely have their own homeowners or renters policy. That policy should end once they move in and are added to yours, rather than running alongside it. Keeping both in place doesn't add coverage since the same belongings and the same person's liability can't be insured twice for extra benefit, and if something happens during the overlap, having two policies can slow down which one actually pays.
Once your partner becomes a named insured, their claims history becomes part of the picture. Insurers generally ask about prior claims for everyone named on a policy, not just whoever applied first. If your partner filed a claim in the past several years, bring it up when you call to add them. Some insurers weigh this heavily in pricing, others barely at all, and finding out now means the number on your binder won't shift later.
Credit also plays a role in most states. Insurers often use credit-based insurance scores as one factor in pricing, so if your partner has limited credit history or past problems, it can affect what the combined policy costs. A handful of states don't allow insurers to use credit this way at all. Either way, it has no bearing on whether your partner can be added as a named insured. It only affects the price, so ask the insurer directly how they factor it in instead of assuming the worst.
Married couples are typically both listed as named insureds automatically when a policy is written. Domestic partners sometimes expect the same, but insurers don't make that assumption without being told, which is exactly why proof of shared residence gets asked for in the first place. Getting this sorted before closing, rather than circling back after move-in, means the declarations page lists the right people from the start and the binder your lender receives already reflects the household actually living there.
Before you call
Have proof of shared residence ready, like both names on the deed, and ask your partner about any past claims or credit issues beforehand. A quick comparison now can catch a better price before your binder is locked in.
