Interested Party vs Additional Insured on Home Insurance
An interested party just gets notified about your policy. An additional insured has coverage under it too.

What your lender gets
Your mortgage lender is almost always listed as an interested party, sometimes called a mortgagee or lienholder. They get copies of your renewal, cancellation notices and claim payments on the dwelling, since they have money in the house too. They don't get coverage for anything of their own.
Who actually needs added
A spouse not on the mortgage, a business partner, or a family trust holding title usually needs to be an additional insured, not just an interested party. That gets them actual protection under the policy, like liability coverage, not just a notice when something changes.
The binder your lender wants
Before closing, the lender needs a binder or declarations page showing them listed correctly, usually as mortgagee or lienholder under the interested party section. Get the name and mailing address exactly as the lender's closing documents state, since a mismatch can delay closing.
What your declarations page shows
Once the policy is issued, check the declarations page for a section naming interested parties separate from named insureds. If someone who should have real coverage, like a co-owner, is only listed as an interested party, call the insurer before closing to fix it.
Get this wrong and closing waits
A lender's name typed wrong, or a co-owner left off as an additional insured, can stall the binder your closing needs. Compare policies now and check the details before you're stuck fixing them last minute.
What happens if the names don't match later
Mortgages get sold. It happens more than people expect, sometimes within the first year of owning the house. When that happens, the new loan servicer needs to be added as the interested party in place of the old one, and the old lender needs to come off. Nobody does this automatically. The notice you get in the mail saying your loan was transferred usually tells you to update your insurance information, and that responsibility falls on you, not the insurer and not the new servicer.
If you skip it, the practical risk shows up at claim time or renewal. Claim payments on dwelling damage are often issued jointly to the homeowner and whoever is listed as mortgagee, because that's who the insurer has on file as having a financial stake in the house. If the name on file is a lender that no longer holds your loan, the check can go to the wrong place, or get held up while it's sorted out. Renewal notices and cancellation warnings go to that same outdated address too, which means the people who need to know your coverage lapsed might be the only one who doesn't.
Adding a second home equity loan or line of credit works the same way. That lender also goes on as an interested party, usually as an additional mortgagee, separate from your primary loan. Most insurers let you have more than one listed. If you take out a HELOC after your policy is already in place, call the insurer or use the policy's online portal to add the new lender rather than waiting for the next renewal, since a gap between taking out the loan and updating the policy is exactly when a lender might ask for proof and find the paperwork doesn't match.
None of this requires rewriting the policy. It's a correction to one section of the declarations page, and most insurers handle it over the phone or through a service request. The part that takes longer is realizing it needs to happen at all, since nothing about the house or the coverage changed, just who's owed notice about it.
Does removing a co-owner or ex-spouse change things
Title changes after closing more than people plan for. Someone gets added to the deed, someone else gets taken off after a divorce or a death, a parent transfers their share to a child. Each of these can affect who should be listed on the policy, and it's easy to assume the insurance is fine because nothing about the house changed. The policy follows who has an insurable interest, not just who holds the mortgage.
If a co-owner is removed from title, they generally should come off the policy too, whether they were a named insured or an additional insured. Leaving them on isn't usually a problem for coverage, but it can create one at claim time if there's a dispute over who's entitled to the payout, especially after a divorce. The reverse matters more. If someone is added to title and not added to the policy, they may have no coverage for their own liability exposure even though they now own part of the house.
Updating who's an insured on the policy is a separate conversation from updating the lender's listing. The lender's interested party status doesn't change just because ownership between the people on title does. It stays listed as mortgagee until the loan itself is paid off, refinanced, or sold to a new servicer, regardless of whose name comes off the deed. Fixing one doesn't take care of the other, so both need a call if both have changed.
The declarations page is where this gets caught. After any change in who owns the house, the named insureds and additional insureds section is worth checking against the current deed. If it still lists an ex-spouse or a deceased parent, or leaves off someone who now owns part of the house, a call to the insurer fixes it. It's a short conversation, but it's one that doesn't happen unless someone remembers to have it.
Before you close
Check the declarations page against your lender's closing documents. The name and mailing address under interested party need to match exactly, and anyone else with a real stake in the house should be listed as an additional insured.
