In a state with a Marketable Record Title Act, a title search generally has to go back 20 to 40 years, with most states landing in the 30- to 40-year range. In a state without one, the search can run much further, sometimes all the way to the original government land patent. How far back a title search goes depends almost entirely on which category your state falls into and on what the examiner finds at the far edge of that window.
Two Different Rules in Two Different Groups of States
Roughly half of U.S. states have enacted some form of Marketable Record Title Act. These statutes set a legal cutoff: once a qualifying recorded transaction sits far enough in the past, older claims against the property are wiped out by operation of law. A searcher in one of these states can stop at the statutory period and treat everything before it as cleared, with narrow exceptions.
In the other states, there is no statutory shortcut. A title examiner traces every transfer in the chain of ownership, checks for breaks, and reviews old encumbrances one by one. Searches in these states typically cost more, take longer, and leave a greater chance that some forgotten interest from the 1800s could cloud the title. If you don’t know which group your state belongs to, a local real estate attorney or title company can answer in a sentence.
The 20- to 40-Year Window and the Root of Title
In states with a Marketable Record Title Act, the search period is measured backward from today. The examiner looks for the most recent recorded transaction that existed at least 20, 30, or 40 years ago, depending on the state’s statutory period. The Model Marketable Title Act uses a 30-year window; many states use 40. A few states apply shorter periods for specific categories like mineral rights.
Whatever document sits at that cutoff becomes the “root of title.” It can be a warranty deed, a quitclaim deed, a probate decree, a tax deed, a court order, or any other recorded instrument that purports to transfer an interest in the land. The examiner then reviews every document recorded from that root forward to the present, looking for mortgages, liens, easements, restrictive covenants, and anything else that could affect ownership.
Claims and interests that arose before the root of title are extinguished automatically. An old mortgage from 1910, a restrictive covenant from 1935, or a claim by a long-forgotten heir all lose their legal force if nobody re-recorded them during the statutory window. No court order or quiet title action is required. The act is self-executing.
One trap catches people off guard. A restriction that originated a century ago but was referenced in a deed recorded 15 years ago is still alive. The act extinguishes interests that are not mentioned in the modern chain. If someone kept the old restriction visible by incorporating it into a recent document, it survives into the current search period.
Searches in States Without a Marketable Title Act
Where no statute cuts off old claims, the search period is dictated by the property’s history rather than the calendar. The examiner works backward until the chain of title is established to the satisfaction of the title insurer, which in some cases means reaching the original government patent conveying the land out of federal or state ownership. Every link in that chain gets reviewed. Any break, competing claim, or unresolved encumbrance has to be addressed on its own terms, because there is no statutory mechanism to clear it.
That is why the cost and timeline of a title search can look so different across state lines on otherwise similar properties. The legal risk tolerance of the title insurer, more than any fixed rule, sets the floor.
Older Interests That Survive the Cutoff
Even in states with a Marketable Record Title Act, not everything older than the root of title is wiped away. Each state’s version of the act carves out exceptions for interests considered too important or too visible to lose through inattention. The specifics vary, but several categories appear consistently and are worth checking regardless of what the search period technically covers.
Government Interests and Federal Tax Liens
Government-held interests, including tax liens, public land claims, and rights held by federal or state agencies, are generally exempt from extinguishment. Public interests do not evaporate because a bureaucracy failed to re-record a document.
Federal tax liens deserve particular attention. The IRS has taken the position that state statutes of limitations cannot affect the duration or existence of a federal tax lien, and courts have consistently upheld this view. State laws that exempt a debtor’s property from creditors likewise do not limit the reach of the federal tax lien. The filing of a Notice of Federal Tax Lien is governed exclusively by the Internal Revenue Code and is not subject to state recording systems.1Internal Revenue Service. 5.17.2 Federal Tax Liens A 40-year title search will not necessarily reveal a federal tax lien if the IRS filed it under different rules, so buyers should request a separate federal tax lien search.
Visible Easements and Utility Rights-of-Way
Easements whose existence is apparent from a physical inspection of the property typically survive the statutory cutoff. A shared driveway, a utility pole line crossing the back of the lot, or a well-worn footpath used by neighbors can remain legally valid even if nothing about them appears in the recent chain of title. The physical evidence itself provides notice, which makes a recording requirement redundant in the eyes of most legislatures.
Rights-of-way held by railroads and public utility companies get similar protection across most states.
Live Mortgages
Active mortgages are typically exempt as long as they have not reached maturity. A mortgage recorded 35 years ago on a 40-year amortization schedule would survive in most states because the obligation has not yet been fully satisfied. The practical risk arises with old mortgages that were paid off but never formally discharged of record. Those phantom liens may or may not be cleared by the act depending on state-specific language, and they frequently require a separate release or quiet title action to resolve.
Mineral Rights
Severed mineral rights sit in their own category. Some states apply the same statutory period to mineral interests as to surface interests. Others have enacted shorter periods specifically for minerals. A handful exempt oil and gas interests entirely while subjecting other minerals like coal or limestone to the act. Many states also have separate “dormant mineral” statutes that deem a mineral interest abandoned if the owner has not used it, leased it, or paid taxes on it for a specified period. In some states, both laws can independently extinguish the same interest.
If you are buying property where mineral rights may have been severed in the past, do not assume the surface search answers the question. The mineral chain is often handled separately.
Conservation Easements and HOA Covenants
Some states have specifically exempted conservation easements from their marketable title acts. Where no exemption exists, a conservation easement is at risk of being extinguished after the statutory period unless the holder re-records a notice of claim.
Homeowner association restrictions face the same pressure. The original covenants governing a subdivision may have been recorded 40 or 50 years ago when the development was first platted. If nobody re-recorded them, the act can wipe out the architectural controls, land-use restrictions, and assessment obligations that the community depends on. This has happened. Some states have addressed it by specifically exempting recorded subdivision restrictions, but many have not.
Why the Title Company May Search Further Back Anyway
The statutory period and the title search period are not necessarily the same thing. Even in states with a Marketable Record Title Act, title insurance companies do not always stop at the statutory cutoff. Many underwriters search further back as a matter of internal policy, particularly for high-value transactions or properties with complex histories.
The reason is risk management. The act tells you what claims can legally survive; the underwriter wants to know what claims might actually exist and whether any of them could fall within an exception. A 40-year act does not mean the title company will ignore a recorded deed from 1920. It means that if the only defect in your title traces back to 1920 and nobody preserved it, the act protects you. The title company may still flag it as a potential underwriting concern.
Notices of Claim You May Encounter in the Chain
Anyone holding an interest that predates the root of title can prevent extinguishment by filing a notice of claim in the county land records. Once recorded, the notice preserves the interest for another full statutory period, and the clock resets. In a state with a 40-year act, filing a notice of claim today keeps the interest alive for another 40 years, and the process can be repeated indefinitely.
For a buyer, the practical point is that these notices will show up in a search. If a notice of claim appears in the records, it signals a surviving old interest that the examiner needs to evaluate on its merits rather than treat as extinguished. A clean search is not just about what the window contains; it is also about what someone deliberately placed inside the window to keep an older claim alive.
