Nearly every American home purchase involving a mortgage includes title insurance, and the policy is unusual among insurance products. It looks backward at defects that already exist rather than forward at events that might occur.
Ownership is a chain, not a document
A deed records one transfer. Legal ownership depends on every prior transfer in that property's history having been valid, along with the discharge of every claim recorded against it.
County land records hold that chain. Before closing, a title search examines the records to identify prior owners, mortgages, liens, easements and judgments attached to the parcel.
The search produces a commitment listing what the insurer found and what it will not cover. Items the parties must resolve before closing appear as requirements.
The risk insured is a defect that already happened
Common defects include a forged signature in an old deed, an heir who was never accounted for, a contractor's lien that was never released, or a clerical error in a recorded document.
These conditions exist at the moment of purchase whether or not anyone has noticed them. The policy pays when such a hidden defect surfaces later and someone asserts a claim.
Because the insured risk lies in the past, the premium is charged once at closing rather than annually. There is no ongoing exposure to price.
Two policies cover two different parties
A lender's policy protects the mortgage holder's security interest and is required by nearly every lender. Its coverage declines as the loan balance is paid down.
An owner's policy protects the buyer's equity and is generally optional. Buyers who decline it are protected only to the extent the lender's policy incidentally clears the record.
The two are issued at closing, often by the same company, and the marginal cost of adding the owner's policy is usually far below issuing it alone.
Prevention is where most of the money goes
Title insurers spend heavily on searching and examining records, and they maintain private databases assembled from public filings. The business model favors finding problems rather than paying for them.
That is why claim payouts are a small share of premiums compared with other insurance lines. The premium buys research and record-keeping as much as it buys indemnity.
Exclusions define the boundary
Standard policies exclude matters a survey would reveal, zoning and government regulation, environmental conditions, and defects the buyer knew about and did not disclose. Those are risks for other instruments.
Endorsements can extend coverage to particular concerns, such as boundary encroachments or restrictive covenants. Each is negotiated and priced separately.
Reading the commitment's exceptions before closing is where a buyer learns what the policy will and will not stand behind, and that document is the substance of the transaction.
