The Properties, the People, and a Problem Nobody Knew About
The story of Romero v. Shih begins not with a legal dispute, but with a driveway that nobody ever questioned — for almost seventy years. In the early 1940s, Edwin and Ann Cutler purchased two adjacent parcels of land in Sierra Madre, a small city in the foothills of Los Angeles County. They built a home on the eastern parcel and, in doing so, constructed a driveway and garden planter that physically crossed onto the western parcel by roughly eight feet. The wall, the fence, the planter, the driveway — all of it was built without anyone drawing the line precisely where the law said it should be. For decades, it simply did not matter. The Cutlers owned both lots.
In 1986, the Cutlers sold the western parcel. The deed made no mention of the encroaching driveway. No easement was expressly reserved. Decades passed, the properties changed hands, and the driveway kept being used as a driveway — because that is what it had always been.1
In 2014, two separate transactions brought two separate families into what would become one of the most significant property rights disputes in California in a generation. Cesar and Tatana Spicakova Romero purchased the western parcel — the one with the legal ownership of that disputed eight-foot strip. Li-Chuan Shih and Tun-Jen Ko purchased the eastern parcel — the one with the driveway that had been sitting on that strip for decades. Neither couple had been told about any encroachments or boundary disputes. Neither seller had disclosed anything. Neither buyer had commissioned a boundary survey before closing.2
The Discovery That Triggered Everything
About a year after moving in, Cesar Romero was doing what many new homeowners do: planning improvements to his yard. He went outside with a measuring tape to sketch out a landscaping project. What he found stopped him cold. The yard was measurably narrower than the property records and purchase documents suggested it should be. He hired a licensed surveyor. The survey confirmed it: the neighbor's concrete block wall, garden planter, and entire driveway were sitting on Romero land.2
The Romeros filed suit against the Shih-Kos. Their position was straightforward under the law: this is our property, the encroachments are a trespass, remove them and pay damages. The Shih-Kos responded with a cross-complaint arguing that when the Cutlers originally divided and sold the western parcel back in 1986, they had implicitly intended for the eastern parcel to retain the right to use that driveway area. In legal terms: they claimed an implied easement. As an alternative, they asked the court to create an equitable easement — a court-fashioned remedy that would compensate the Romeros for the burden placed on their property while allowing the driveway to remain.2
1940s
Cutlers build the driveway. The Cutler family constructs a home on the eastern parcel with a driveway and planter that encroaches roughly eight feet onto the adjacent western parcel — which they also own. No legal documentation of the arrangement is created.
1986
The western parcel is sold — without disclosing the encroachment. The Cutlers sell the western lot. The deed makes no mention of easements or the encroaching driveway. The two properties are now in separate ownership for the first time, but the physical arrangement remains unchanged.
2014
Both properties are sold again — to strangers who know nothing. The Romeros purchase the western parcel. The Shih-Kos purchase the eastern parcel and its driveway. Neither seller disclosed the boundary issue. Neither buyer verified the boundary. Neither transaction mentioned the encroachment.
2015
The Romeros discover the problem. While measuring for a landscaping project, Cesar Romero notices the yard is smaller than expected. A professional survey confirms the encroachment. The Romeros demand the Shih-Kos remove the driveway and planter from their land.
2020
Trial court rules for the Shih-Kos. After a bench trial, the Los Angeles County Superior Court finds that an implied easement was created when the Cutlers divided the parcels in 1986. The historical use of the driveway, combined with evidence of the parties' original intent, satisfies the legal standard.
2022
Court of Appeal reverses. The Second District Court of Appeal concludes that because the easement was effectively "exclusive" — it prevented the Romeros from using their own land in that area — it could only have been created through a written instrument, not by implication. The Shih-Kos appeal to the California Supreme Court.
February 2024
California Supreme Court reverses the Court of Appeal. In a unanimous opinion authored by Justice Kruger, the Supreme Court holds that an implied easement can be legally enforceable even if it effectively precludes the property owner from using that area — provided clear evidence demonstrates the original parties intended the arrangement to continue permanently.
The Legal Question at the Heart of the Case
To understand why this case drew attention from property law practitioners throughout California, it helps to understand what was actually being argued — and what the law said before this ruling.
What Is an Implied Easement?
California law recognizes that easements — the legal right to use someone else's land for a specific purpose — do not always need to be spelled out in writing. When a single owner divides a property into two parcels, and one parcel has historically been used in a way that benefits or burdens the other, the courts may recognize an "implied easement" based on what the parties clearly intended, even if they never put it in a deed.3
The traditional requirements for an implied easement in California are: (1) the properties were once under common ownership; (2) the easement is reasonably necessary to the enjoyment of the dominant parcel; and (3) the existing use at the time of division was of such a character that the parties must have intended for it to continue.3
The Problem the Court of Appeal Created
The Court of Appeal's reversal rested on a specific concern: the Shih-Kos were not just claiming a shared right-of-way or a utility access strip — their driveway took up essentially the entire eight-foot disputed area, effectively denying the Romeros any practical use of their own land in that strip. The appellate court concluded that this level of exclusivity could only be created by a written instrument. It drew from case law on prescriptive easements — which require adverse, continuous, open, and exclusive use over five years, plus payment of taxes on the disputed land — and applied that logic to implied easements as well.4
The practical consequence of that ruling: no California property owner whose driveway, structure, or improvement encroaches on a neighbor's land could ever establish a right to keep it there based on implied intent alone, no matter how clear the historical evidence. The only option would be formal adverse possession — a much harder standard to meet.
What the Supreme Court Actually Decided
The California Supreme Court, in a unanimous opinion, rejected the Court of Appeal's reasoning and drew a clear distinction between prescriptive easements and implied easements. Prescriptive easements arise from unauthorized use — someone uses land without permission long enough to acquire a legal right. Implied easements, by contrast, arise from a real estate transaction, and their purpose is entirely different: to give effect to what the original parties actually intended when they divided property and sold it.5
The Court held that there is no blanket prohibition against an implied easement that is effectively exclusive. What matters is the evidence — specifically, whether the parties to the original transaction in 1986 understood and intended that the driveway would continue to serve the eastern parcel permanently. The Court found the trial court's conclusions were supported by the evidence and remanded for the Court of Appeal to reconsider that question under the correct legal standard.5
Key Legal Principles from Romero v. Shih
- Implied easements are transaction-based, not use-based. They arise from the intent of parties to a property sale — not from years of unauthorized use the way prescriptive easements do.
- Exclusivity does not automatically invalidate an implied easement. Even if an easement effectively prevents the property owner from using that area, it can still be legally enforceable if the evidence of intent is sufficiently clear.
- The evidentiary standard is high. Courts will not lightly recognize an implied easement that burdens a property owner heavily. The evidence of original intent must be clear and substantial.
- Deeds and title reports do not tell the whole story. An encroachment or easement may bind future buyers even if it appears nowhere in the recorded documents.
- Non-disclosure does not erase legal obligations. Neither the Romeros nor the Shih-Kos were told about the boundary issue — but the law applied to them anyway.
What This Case Reveals About Real Estate Transactions in Southern California
Romero v. Shih is a court opinion, but it is also something else: a concrete illustration of how disputes that cost years of litigation and tens of thousands of dollars in legal fees routinely begin with the most mundane moments — a yard measurement, a renovation project, a survey done for the first time in thirty years.
The Non-Disclosure Problem
California law places significant obligations on sellers of residential property to disclose known material facts — including surveys, easements, encroachments, and boundary disputes — in the Transfer Disclosure Statement and the Seller Property Questionnaire. The purchase agreements used by both parties in this case explicitly asked about these issues and disclosed nothing.2
Whether the sellers in 1986 and 2014 knew about the encroachment is a factual question this case never fully resolved. But the legal lesson is plain: a disclosure obligation exists regardless of how old the encroachment is or how long ago the boundary was misdrawn. If a seller knows — or should know — that a structure on or near the property line has never been surveyed, that fact can be a material one. California's failure-to-disclose laws exist precisely because buyers cannot be expected to discover what they have no reasonable way to find.
The Survey Problem
Standard real estate purchase transactions in California do not automatically require a boundary survey. A title report will show recorded easements and liens, but it will not tell a buyer whether the physical structures on or adjacent to a property conform to the legal boundary lines. The only way to know that is a licensed boundary survey — and in a competitive market where buyers waive contingencies and close quickly, surveys are routinely skipped.
The Romeros followed the standard process. They bought a property, the deal closed, and they moved in. Nothing in the transaction indicated there was anything to worry about. One year later, they discovered they were in a legal dispute with their neighbor over eight feet of land — a dispute that would eventually be decided by the highest court in the state.
The Title and Documentation Gap
One of the most important takeaways from the Supreme Court's reasoning is this: an easement that does not appear in any deed, title report, or recorded document can still be legally enforceable against a buyer who had no knowledge of it. The Court was careful to note that the evidentiary standard is high — but high does not mean impossible. Where historical use is long-standing, physical evidence is clear, and the circumstances at the time of the original property division strongly suggest the parties understood the arrangement, courts will give effect to that intent.
For buyers, sellers, and their attorneys in Los Angeles County and throughout Southern California, this means that the recorded documents represent the beginning of due diligence — not the end of it.
Why This Matters
Four Things Every Southern California Property Owner Should Take From This Case
The dispute in Romero v. Shih began with two families who did nothing wrong. They bought homes. They followed the standard process. Years later, they were in a lawsuit that reached the California Supreme Court — because boundary problems left unresolved and undisclosed do not disappear. They transfer with the property.
Get a Boundary Survey Before You Close
A title report shows recorded documents. A boundary survey shows what is physically happening on the ground. In older neighborhoods where lots were subdivided decades ago, they are not always the same thing.
Sellers Must Disclose What They Know
California law requires disclosure of known easements, encroachments, and boundary disputes. "The fence has always been there" is not an answer — it is a reason to investigate and disclose. Failing to do so exposes sellers to significant legal liability after closing.
Unwritten Easements Can Be Legally Binding
After this ruling, California property owners cannot assume that an easement absent from a deed or title report does not exist. Long-standing use patterns at the time a parcel was divided can create enforceable legal rights — even decades later.
Act Early If You Discover a Problem
Boundary and easement disputes do not resolve themselves with time — they often become harder to contest the longer a use continues. If a survey, renovation, or sale reveals an unexpected encroachment, legal counsel should be consulted promptly.
How DiJulio Law Group Approaches Easement and Boundary Disputes
Boundary disputes and easement cases in Southern California involve layers of legal analysis: historical chain of title, the physical facts on the ground, applicable statutes, and — after Romero v. Shih — a clearer but demanding standard for implied easement claims. For homeowners, the stakes are personal and often significant. An eight-foot strip of land may sound like a minor matter until it determines whether a driveway exists, whether a structure can remain, and what a property is ultimately worth.
