A home purchase transfers a legal interest in land, and that interest can carry defects invisible at a showing. The title search exists to find them before closing.
Claims attach to property, not people
Many obligations are recorded against a parcel rather than against an individual, which means they survive a change of ownership unless they are cleared.
Unpaid contractor work can produce a mechanic's lien, and unpaid taxes produce a tax lien, both recorded in the public record for that property.
A buyer who closes without resolving these acquires the house and the encumbrances together, which is why lenders will not fund a loan until the record is examined.
The search reconstructs a chain
The examiner traces recorded documents backward through deeds, mortgages, releases, judgments and easements to establish an unbroken sequence of transfers.
Gaps and inconsistencies are the target: a mortgage with no recorded satisfaction, a deed signed by only one of two owners, a boundary described differently in two documents.
Most searches find something minor and resolvable. The work is routine precisely because problems are common enough to expect.
Easements limit use without limiting ownership
An easement grants someone a right to use part of the property, commonly a utility's right to maintain lines or a neighbor's right of access.
These do not prevent a sale, but they constrain what an owner can build and where, which can matter more than the buyer anticipated.
Because they are recorded, they appear in the search and should be read rather than skimmed, since they run with the land indefinitely.
Insurance covers what the search misses
Title insurance is purchased at closing and covers defects that existed before the policy date but were not discovered, such as forged signatures or unknown heirs.
It is priced as a one-time premium rather than an ongoing one, because it insures against past events rather than future ones.
A lender's policy protects the lender's interest only, which is why owner's coverage is a separate policy addressing the buyer's own equity.
Practice varies by state
Some states handle closings through title or escrow companies, while others require an attorney to conduct the closing and render an opinion on title.
Recording systems and the priority rules that determine which claim outranks another are set at the state level and differ meaningfully.
The general process is consistent, but the specifics and the costs depend on jurisdiction and change over time, which is where local professional guidance applies.
