Boundary disputes are among the most personal cases in real estate law. They involve a few feet of ground, a fence, a driveway, a row of trees — and a neighbor you will still see every day after it is over. They are also legally technical in ways that surprise most homeowners, because the rules that decide them turn on doctrines with narrow, specific elements.
ROMO Law Group handles boundary, encroachment, easement, and quiet title matters for property owners in Encino and throughout California. This page sets out the law that actually governs these disputes, including the doctrines neighbors most often invoke incorrectly.
Quiet title: establishing what you own
A quiet title action under Code of Civil Procedure sections 760.010 through 764.080 asks the court to determine title against competing claims. The pleading requirements are specific. Section 761.020 requires a verified complaint that includes the property description — both the legal description and the street address, not one or the other — the plaintiff’s title and its basis, the adverse claims to be determined, the date as of which determination is sought, and a prayer for determination against the adverse claims. Where title rests on adverse possession, the complaint must allege the specific facts constituting it.
One feature distinguishes quiet title from most civil litigation. Under section 764.010, the court shall not enter judgment by default. Even against a defendant who never appears, the plaintiff must put on evidence of title at a prove-up hearing and the court must render judgment in accordance with the evidence and the law. There is no shortcut.
On timing, there is no limitations period specific to quiet title; courts apply the period of the underlying theory. Under Muktarian v. Barmby (1965) 63 Cal.2d 558, no cause of action accrues while the plaintiff remains in undisturbed possession — the clock does not begin until possession is lost or the adverse claim becomes clearly hostile.
Recording a lis pendens
A boundary or easement claim generally qualifies as a “real property claim” under Code of Civil Procedure section 405.4, which expressly reaches actions affecting title, the right to possession, or the use of an identified easement. Recording a notice of pending action gives constructive notice to later purchasers and encumbrancers.
The procedural requirements are strict and frequently botched. Section 405.22 requires service by registered or certified mail, return receipt requested, on all known addresses of adverse parties and all record owners per the latest assessment roll, before recording. On an expungement motion the burden is on the party who recorded: section 405.32 directs the court to expunge unless the claimant establishes the probable validity of the claim by a preponderance of the evidence. And section 405.38 makes attorney fees mandatory to the party prevailing on any motion under the chapter, absent substantial justification or circumstances making an award unjust. That fee provision runs both ways and is one of the few genuine fee-shifting hooks in a boundary case.
Adverse possession: the tax element decides most cases
A claimant asserting adverse possession must show possession that was actual, open and notorious, hostile to the true owner, exclusive, and continuous for five years, under claim of right or color of title. Under Code of Civil Procedure section 325(a), land held under claim of right is deemed possessed only where it has been protected by a substantial enclosure or usually cultivated or improved.
Then there is the element that ends most residential claims. Section 325(b) provides that adverse possession may not be established unless the claimant proves that they, or their predecessors, timely paid all state, county, or municipal taxes levied and assessed upon the land for the full five-year period — and that payment must be established by certified records of the county tax collector.
In a typical suburban strip-of-land dispute, the contested ground sits inside the record owner’s assessor’s parcel. The county bills the record owner. The record owner pays. Assessors do not issue separate bills for unrecorded slivers of land. So the encroaching neighbor cannot produce certified tax collector records showing they paid the taxes on that land — and the claim fails on the seventh element regardless of how open, obvious, or long-standing the possession was.
Separately, Civil Code section 1007 provides an absolute bar as to public property: no possession, however long continued, of land, water, water rights, easements, or other property dedicated to public use by a public utility or dedicated to or owned by the state or a public entity ever ripens into title against the owner. Property adjoining a city easement, a flood control channel, or a dedicated utility corridor cannot be acquired by adverse possession.
Prescriptive easements: use, not ownership
A neighbor who cannot win adverse possession will often pivot to prescription. A prescriptive easement requires use that was open and notorious, continuous and uninterrupted for five years, hostile or adverse, and under claim of right. Two differences from adverse possession drive the analysis:
- No tax payment requirement. Section 325(b) does not apply, which is precisely why the claim gets made.
- No exclusive possession. A prescriptive easement conveys a right of use, not ownership. In Mehdizadeh v. Mincer (1996) 46 Cal.App.4th 1296, the court held that an interest so comprehensive that it supplies the equivalent of ownership is an estate, not an easement — reasoning that allowing an “exclusive prescriptive easement” would let a claimant obtain the practical equivalent of adverse possession while evading the tax statute. Silacci v. Abramson (1996) 45 Cal.App.4th 558 held the concept has no application to a simple backyard dispute between residential neighbors.
Use that is permissive can never ripen into prescription. A written, revocable license granted to a neighbor — and documented — is the standard defensive measure when a property owner is willing to tolerate a use but not to lose the right to stop it later.
Content stating flatly that California easements can never be exclusive is now inaccurate. In Romero v. Shih (2024) 15 Cal.5th 680, the California Supreme Court held that an implied easement may be exclusive in scope even where it effectively precludes most practical use of the burdened area. The Court distinguished the Silacci and Mehdizadeh line on the ground that the anti-exclusivity rule exists to protect the integrity of the adverse possession tax statute, and implied easements rest on the parties’ mutual intent in a land transaction rather than on unilateral adverse conduct.
Other easement types, and how easements end
Beyond prescription, easements arise by express grant or reservation, by implication from prior use, by necessity, by estoppel where a licensee makes substantial expenditures in reliance, and by dedication. Easements by necessity require strict necessity — no other possible access, even if alternative access would be inconvenient, difficult, or costly — together with common ownership of the parcels at the time of the severing conveyance.
Civil Code section 811 sets out how a servitude is extinguished: by merger of the servitude and the servient tenement in the same person; by destruction of the servient tenement; by an act on either tenement by the owner of the servitude, or with their assent, incompatible with its nature or exercise; and, where the servitude was acquired by enjoyment, by disuse for the prescriptive period. Note the limit in that last one — mere non-use does not extinguish an express easement. A recorded easement someone has not used in thirty years is still there.
The agreed-boundary doctrine is narrower than people think
“The fence has been there since before either of us bought” is the most common argument in a California boundary dispute, and standing alone it is not a legal position. The agreed-boundary doctrine requires three things: an uncertainty as to the true boundary line, an agreement between the coterminous owners fixing that line, and acceptance and acquiescence in the agreed line for a period equal to the statute of limitations, or under circumstances where substantial loss would be caused by a change of position.
In Bryant v. Blevins (1994) 9 Cal.4th 47, the California Supreme Court held that the doctrine should not be applied where existing legal descriptions provide a reasonable basis for fixing the boundary and the claimant fails to demonstrate that genuine uncertainty about the true line led to an agreement. Long acquiescence in a fence is not a substitute for proof of uncertainty and agreement. Where the parcels come from a modern recorded subdivision map that a licensed surveyor can retrace, the uncertainty element is generally unavailable.
Encroachments: removal, or a court-imposed easement
The default rule is that a landowner is entitled to a mandatory injunction requiring removal of an encroachment, with trespass and nuisance claims available alongside it.
The exception is the relative hardship doctrine, sometimes called an equitable easement. As stated in Hirshfield v. Schwartz (2001) 91 Cal.App.4th 749, three factors must all be present before a court will deny an injunction and instead impose an easement with compensation:
- The encroacher must be innocent — the encroachment must not be willful or negligent;
- Unless the rights of the public would be harmed, the court should grant the injunction if the plaintiff will suffer irreparable injury regardless of the injury to the defendant;
- The hardship to the defendant from granting the injunction must be greatly disproportionate to the hardship caused to the plaintiff.
The burden is on the encroacher, and courts apply the doctrine sparingly. The innocence prong is where most claims collapse: a neighbor who built without obtaining a survey, or who proceeded after being put on notice, is generally not innocent for these purposes. The practical lesson runs in both directions — get a survey before you build, and put an encroaching neighbor on written notice promptly.
Trees, fences, and the statutes people do not expect
Trees
Civil Code section 833 provides that trees whose trunks stand wholly on one owner’s land belong to that owner, even if the roots grow into a neighbor’s land. Section 834 provides that trees whose trunks stand partly on the land of two or more coterminous owners belong to them in common — which means a co-owned boundary tree cannot be removed or materially harmed by one owner acting alone.
The consequences of getting this wrong are severe. Code of Civil Procedure section 733 makes a person who cuts down or carries off a tree liable for treble damages. Civil Code section 3346 sets damages at three times the sum that would compensate for the actual detriment, reduced to double where the trespass was casual or involuntary or the defendant had probable cause to believe the land was their own. Damages are reduced to actual detriment where the trespass resulted from an improper survey, provided the defendant or a predecessor procured it and it was performed by a licensed land surveyor. Actions under section 3346 must be commenced within five years.
And the multiplier is not limited to the replacement cost of the tree. In Fulle v. Kanani (2017) 7 Cal.App.5th 1305, the court held that damages for annoyance, discomfort, and mental anguish from intentional injury to trees are subject to doubling or trebling under section 3346. Tree cases can be worth considerably more than the plant.
A property owner may trim encroaching branches and roots back to the property line at their own expense, but may not damage or destroy the tree’s health. Exceeding that scope converts lawful abatement into timber trespass.
Shared fences
The Good Neighbor Fence Act of 2013, Civil Code section 841, presumes that adjoining landowners share an equal benefit from a dividing fence and are equally responsible for the reasonable costs of construction, maintenance, or necessary replacement.
The presumption is rebuttable by a preponderance of the evidence that equal responsibility would be unjust, considering whether the financial burden to one owner is substantially disproportionate to the benefit, whether the cost exceeds the difference in property value before and after the work, whether an equal share would be an undue hardship, whether the work is unnecessary or excessive, and whether it reflects one owner’s aesthetic preferences. A court may order a contribution of less than an equal share, or none at all.
Section 841 requires a landowner intending to incur costs for a shared fence to give 30 days’ prior written notice to each affected adjoining landowner, describing the problem with the fence, the proposed solution, the estimated cost, the proposed cost-sharing approach, and the proposed timeline. Failing to send that notice is the single most common reason a homeowner who unilaterally builds a fence cannot recover half the cost from the neighbor. Send it first, in writing, with the estimate attached.
Spite fences
Civil Code section 841.4 makes any fence or structure in the nature of a fence unnecessarily exceeding 10 feet in height, maliciously erected or maintained for the purpose of annoying an adjoining owner or occupant, a private nuisance. Wilson v. Handley (2002) 97 Cal.App.4th 1301 held that a row of trees planted along or near a property line to separate or mark it is a “structure in the nature of a fence” — so a wall of fast-growing evergreens planted to block a view can fall within the statute. Note that many California cities impose stricter height limits by ordinance; the state statute is a floor, not the operative rule everywhere.
Deadlines
| Claim | Authority | Period |
|---|---|---|
| Trespass upon or injury to real property | CCP § 338(b) | 3 years |
| Private nuisance | CCP § 338(b) | 3 years |
| Timber trespass | Civ. Code § 3346 | 5 years from the trespass |
| Adverse possession / prescriptive period | CCP §§ 318, 325 | 5 years |
| Quiet title | — | Period of the underlying theory; no accrual while plaintiff is in undisturbed possession |
The distinction that decides many of these cases is between a permanent and a continuing trespass. A permanent trespass is an intrusion under circumstances indicating an intention that it be permanent; the period runs once and all past and future damages must be recovered in a single action. A continuing trespass is one that may be discontinued or abated — a condition that can be stopped at any time, in a reasonable manner, and at reasonable cost. For a continuing trespass, successive actions may be brought and the claim is not barred merely because the condition has stood for more than three years, although recovery is generally limited to the three years preceding filing. Whether a trespass is continuing or permanent is a question of fact.
A removable fence, shed, or driveway is typically analyzed as a continuing trespass. “You waited too long” is one of the most common things a neighbor says, and one of the most frequently wrong.
The role of the survey
Almost every boundary case turns on a licensed survey. Business and Professions Code section 8762 requires a licensed land surveyor to file a record of survey with the county surveyor after a field survey that discloses material evidence or physical change not appearing on any prior map, a material discrepancy with recorded information, evidence that could support alternate line positions, the establishment of points or lines not ascertainable from recorded documents, or the setting of monuments not shown on any existing map. Filing is due within 90 days of setting boundary monuments or completing the field survey, whichever comes first.
A recorded record of survey is public, indexed at the county recorder, and prepared by a licensed professional subject to discipline. It is ordinarily the most persuasive single piece of evidence in a boundary case. It is also, under Civil Code section 3346, the document that can reduce timber trespass damages from treble to actual detriment for a defendant who relied on it in good faith. Getting a licensed survey before you cut, build, or fence is the cheapest risk management available in this area of law.
A candid note on cost
California follows the American Rule. Code of Civil Procedure section 1021 leaves attorney compensation to the parties’ agreement except as otherwise provided by statute, and there is no fee-shifting statute for quiet title, boundary, encroachment, prescriptive easement, agreed-boundary, or Good Neighbor Fence Act claims. Each side generally bears its own fees.
The meaningful exceptions are the mandatory fee provision on lis pendens motions under section 405.38, contractual fee clauses in CC&Rs, easement agreements, or purchase documents, and — sometimes the real answer — a title insurance policy’s duty to defend. Reviewing the title policy and its survey exceptions is one of the first things worth doing in a boundary matter, because it can change the economics entirely.
How we approach these disputes
Most boundary matters do not need to become trials, and the ones that settle well tend to settle because one side assembled the record early: a current licensed survey, the chain of title and recorded easements, the assessor’s parcel data and tax records, historical aerial imagery, and a clear written demand that identifies the doctrine actually in play. Where a negotiated boundary line agreement or a written, recorded easement can resolve the matter, that is usually the better outcome for a client who has to keep living next door.

Frequently asked questions
My neighbor's fence has been on my property for twenty years. Is it too late to do anything?
Usually not. California distinguishes between a permanent trespass, where the limitations period runs once from the original intrusion, and a continuing trespass, where the condition can be discontinued or abated at reasonable cost. Fences, sheds, and similar removable structures are typically analyzed as continuing trespasses, so a new claim accrues as the condition persists — though recovery of damages is generally limited to the three years preceding filing. Whether a trespass is continuing or permanent is a question of fact.
Can my neighbor take part of my yard by adverse possession?
Rarely, and the reason is taxes. Code of Civil Procedure section 325(b) requires a claimant to prove, through certified county tax collector records, that they timely paid all taxes levied and assessed on the land for the full five-year period. In a typical strip-of-land dispute the disputed area sits inside the record owner's assessor's parcel, the record owner is billed and pays, and the neighbor cannot make the showing. Most residential adverse possession claims in California fail on this element.
What is the difference between adverse possession and a prescriptive easement?
Adverse possession transfers ownership; a prescriptive easement grants only a right of use. A prescriptive easement requires five years of open, notorious, continuous, hostile use under claim of right — but no payment of taxes. It also cannot be so comprehensive that it functionally dispossesses the owner. Silacci v. Abramson (1996) 45 Cal.App.4th 558 held the concept of an exclusive prescriptive easement has no application to a simple residential backyard dispute.
The fence has been in the same place for forty years. Doesn't that fix the boundary?
Not by itself. The agreed-boundary doctrine requires uncertainty as to the true line, an agreement between the owners fixing it, and acceptance and acquiescence for five years or circumstances where a change would cause substantial loss. In Bryant v. Blevins (1994) 9 Cal.4th 47, the Supreme Court held the doctrine should not be applied where existing legal descriptions provide a reasonable basis for fixing the boundary and the claimant cannot show genuine uncertainty led to an agreement. A modern recorded tract map that can be resurveyed generally defeats the uncertainty element.
Who pays for a shared fence in California?
Civil Code section 841, the Good Neighbor Fence Act, presumes adjoining landowners share an equal benefit from a dividing fence and are equally responsible for the reasonable costs of construction, maintenance, and necessary replacement. The presumption is rebuttable by a preponderance of the evidence that equal responsibility would be unjust. Critically, a landowner intending to incur costs must give 30 days' prior written notice to each affected adjoining landowner describing the problem, the proposed solution, the estimated cost, the proposed cost sharing, and the timeline. Skipping that notice is the most common reason a homeowner cannot recover a contribution.
