Boundary Line Disputes Between Neighboring Property Owners in Illinois
A new fence appears several feet beyond the line an owner believed was correct. A driveway crosses the edge of another parcel, or a planned addition reveals that two surveys do not agree. These discoveries can place valuable land, future sales, and neighbor relationships at risk. Berardi and Associates, LLC represents property owners in Homer Glen and throughout Will, Cook, DuPage, Grundy, Kane, and Kankakee counties when boundary questions require a documented legal response.
Boundary line disputes should be addressed through deeds, surveys, historical records, and the parties’ conduct rather than assumptions about where a fence or hedge has always stood. Even a narrow strip can affect access, improvements, title coverage, and the marketability of both properties.
Why Recorded Descriptions and Physical Markers Conflict
A deed describes the property conveyed, but interpreting that description on the ground may require a licensed surveyor. Old stakes may have moved, earlier measurements may be inaccurate, and fences are sometimes installed for convenience instead of directly on a legal boundary. A survey prepared for one owner may also rely on different monuments or records than a neighbor’s survey.
Our attorneys examine deeds, plats, prior surveys, easements, title documents, and municipal records to identify the source of the disagreement. The review may reveal a drafting error, an encroachment, an unrecorded understanding between former owners, or competing interpretations that require further evidence.
Evidence Worth Preserving Early
Owners should photograph fences, sheds, driveways, landscaping, drainage features, and survey markers before anything changes. They should also retain purchase documents, title policies, permits, correspondence, contractor records, and photographs showing how the disputed area was historically used. Statements from prior owners or longtime neighbors may help establish when a feature appeared and whether anyone objected.
A Survey Is Strong Evidence, Not the Final Word
A survey is important evidence, but it does not automatically decide every dispute. Courts may also consider possession, agreements, and long-term conduct. In Joiner v. Janssen, 85 Ill. 2d 74 (1981), the Illinois Supreme Court confirmed that possession up to a visible and ascertained boundary can establish title even when the parties were mistaken about the true line, and that hostile possession does not require ill will or knowledge that the deed says otherwise. Illinois appellate courts have likewise found that conflicting surveys and evidence about a long-standing fence can create factual questions that cannot be resolved on summary judgment. See Lapinski v. Law, No. 4-14-0103 (Ill. App. Ct. 4th Dist. Feb. 17, 2015) (unpublished order under Supreme Court Rule 23).
The practical lesson is that the full history of the disputed strip may matter as much as the measurements.
Avoid Actions That Can Worsen the Conflict
Removing a fence, blocking a shared driveway, entering the disputed area, or damaging an improvement can produce additional claims. An owner should not assume that a survey permits immediate self-help. Written communication that identifies the concern without conceding ownership may create room for investigation while reducing the chance of an unnecessary confrontation.
Before work continues, we may recommend requesting the neighbor’s survey, commissioning an independent survey, reviewing title insurance notice requirements, or asking both surveyors to compare their findings. The firm’s real estate dispute services include negotiation and litigation involving encroachments and disputed ownership interests.
If a neighbor has moved a marker, started construction, or claimed part of your parcel, contact us before responding or signing an agreement. We can assess the records, communicate the objection clearly, and consider whether immediate action is needed to preserve existing conditions.
What Your Title Policy May Not Cover
Owners often assume a title policy answers a boundary question. Standard owner’s policies typically contain a general exception for encroachments, overlaps, boundary line disputes, and other matters that a correct survey would disclose but that do not appear in the public records. Extended coverage, a current survey, or specific endorsements may change that result.
The policy also imposes notice obligations. An owner who delays reporting a claim can jeopardize coverage. Locating the policy and reading its conditions is an early step, not an afterthought.
Resolution May Not Require a Trial
Some disputes can be resolved through a boundary line agreement, easement, license, property transfer, or modification of the proposed improvement. Any agreement should describe the affected land accurately, state the parties’ rights and responsibilities, address maintenance and expenses, be signed by all record owners, and be recorded so that it binds later purchasers. Informal permission leaves the same problem for the next buyer.
Two details are easy to miss. First, a conveyance or exchange of a strip between adjoining owners is exempt from the Illinois Plat Act under 765 ILCS 205/1(b)(3), but local subdivision and zoning review may still apply, and moving a line can create a nonconforming lot or a setback violation. Second, if either parcel is mortgaged, lender consent or a partial release may be required before the transfer is effective as intended.
Mediation or direct negotiation may preserve a workable relationship between neighbors. When no agreement is possible, a lawsuit may seek declaratory relief, quiet title, ejectment, damages, or an injunction requiring construction to stop or an encroachment to be removed. Suit is filed in the county where the land is located, and the judgment should be recorded so the resolved line appears in the chain of title. Courts weigh the equities before ordering a structure torn down, so a small and unintentional encroachment may end in damages or a recorded easement rather than demolition. The correct claim and remedy depend on the evidence and the owner’s practical objective.
Long-Term Use Can Affect Ownership Claims
Illinois recognizes legal theories that may move a boundary despite the language in a deed.
Adverse possession. Under 735 ILCS 5/13-101, a claimant must prove twenty years of possession that is (1) continuous, (2) hostile or adverse, (3) actual, (4) open, notorious, and exclusive, and (5) under a claim of title inconsistent with that of the true owner. Every element must be established by clear and unequivocal evidence, and all presumptions favor the record owner. Shorter seven-year periods exist in narrow circumstances involving color of title and payment of taxes under 735 ILCS 5/13-107 and 13-109.
Boundary by agreement or acquiescence. This is a distinct theory, not a relabeled adverse possession claim. Illinois cases hold that a boundary may be fixed by a parol agreement followed by possession, by an agreement implied from unequivocal acts and declarations plus acquiescence for a considerable period, or by undisturbed possession for more than twenty years. See Ginther v. Duginger, 6 Ill. 2d 474 (1955). Because an implied agreement can be shown without a full twenty years of acquiescence, a neighbor may raise this theory earlier than expected, which is one reason a documented objection matters.
We evaluate whether the facts support or defeat these claims and explain the available remedies. Information about the lawyers who handle the firm’s matters is available on the attorneys page.
Turn an Uncertain Line Into a Recorded Answer
Property lines affect more than the current disagreement. An unresolved issue can delay refinancing, complicate a sale, or pass to the next owner. Owners benefit from a result that is legally valid, accurately documented, and usable in future transactions. Berardi and Associates, LLC can review the evidence and pursue an agreement or court order that establishes the parties’ rights. Contact us today to arrange a consultation about the disputed boundary.
