# Boundary Lines, Surveys, and Title Defects in New York Residential Purchases (/docs/playbooks/buyer/article-082-boundary-lines-surveys-and-title-defects-in-new-york-residential-purchases)



Overview [#overview]

The legal description of a property — the words in the deed that define what the buyer is purchasing — governs the physical boundaries of the parcel. In theory, legal descriptions and physical boundaries coincide. In practice, they frequently do not. Encroachments, boundary disputes, gaps or overlaps between adjacent parcel descriptions, and easements that affect specific portions of the property are common title defects that are only fully revealed through a combination of a professional land survey and a thorough title search.

In New York State, title insurance is the primary risk transfer mechanism that protects buyers against losses arising from defects in the chain of title — prior ownership claims, recorded liens, and recording errors. However, title insurance has specific exclusions: matters visible on a survey (encroachments, boundary disputes, easements apparent from inspection) may be excluded from coverage unless the buyer specifically requests and pays for an endorsement removing the survey exception. Buyers who do not obtain a current survey before closing accept physical boundary risk that title insurance may not cover.

This article is distinct from Article 80 (which covers easement types in depth). It focuses on boundary survey mechanics, title defect identification, and the workflow for resolving defects before closing.

How the Market Actually Works [#how-the-market-actually-works]

**The title search reviews the chain of title in the public land records.** In NYS, deeds, mortgages, judgments, liens, and other encumbrances are recorded in the county clerk's office of the county where the property is located. A title search examines these records — typically for the past 40–60 years, though older properties may require deeper searches — to identify any defects in the seller's chain of title.

**Title insurance issues an owner's policy protecting the buyer against undiscovered title defects.** The policy covers losses from: prior ownership claims, forged or fraudulently obtained deeds, recording errors, undisclosed liens or mortgages, and other matters that a thorough search should have but did not discover. Standard title policies in NYS include a "survey exception" — they do not insure against matters that would be disclosed by a current survey. To remove the survey exception, the buyer must provide a current survey and pay for an endorsement.

**A survey establishes the property boundaries as physically located on the ground.** A land survey conducted by a licensed NYS land surveyor measures and maps the parcel boundaries based on the recorded deed description, relates them to physical monuments and reference points, and identifies any discrepancies between the recorded description and actual physical conditions. A survey for a typical residential parcel costs $1,000–$3,500 *(verify locally — costs vary by parcel size, complexity, and surveyor market)*.

**Encroachments are the most common survey finding in urban and suburban NYS.** An encroachment occurs when a structure on one property extends across the boundary line onto an adjacent property. Common encroachments: fences erected on the wrong side of the property line, driveways that pave over a portion of a neighbor's lot, building overhangs or bay windows that project across the line, and stoops or retaining walls that extend beyond the parcel boundary.

**Gaps and overlaps in adjacent deed descriptions create boundary ambiguity.** In older NYS subdivisions and rural areas, deed descriptions prepared decades apart may not be internally consistent — two adjacent parcels whose descriptions are measured independently may leave a narrow gap or create an overlap. These discrepancies require surveying and, if material, a boundary line agreement between neighboring property owners or a quiet title action.

**Judgment liens, unpaid taxes, and mechanic's liens attach to real property and are discoverable through the title search.** A judgment against the seller (from a court proceeding) attaches to all real property the seller owns in the county where it is docketed. If not satisfied before closing, the judgment lien transfers to the property. Similarly, unpaid property taxes and special assessments are liens that must be paid at closing. Mechanic's liens — filed by contractors for unpaid construction work — attach to the property and survive transfer unless discharged.

Strategic Approach for Buyers [#strategic-approach-for-buyers]

Title Review Checklist [#title-review-checklist]

> **Phase 1 — Pre-Contract Title Intelligence**
>
> * [ ] Confirm the property's legal description matches the listing address and parcel identifier (tax map number)
> * [ ] Request a preliminary title search from the title company immediately after offer acceptance
> * [ ] Identify the property's county of recording and confirm the title search covers the correct county records

> **Phase 2 — Title Commitment Review**
>
> * [ ] Review Schedule A (property description, current ownership) for accuracy
> * [ ] Review Schedule B-1 (requirements for insuring title) for items that must be resolved before closing
> * [ ] Review Schedule B-2 (exceptions to coverage) for recorded easements, restrictions, and covenants
> * [ ] Flag the survey exception — determine whether to obtain a survey and remove this exception

> **Phase 3 — Survey Review**
>
> * [ ] Commission a current survey from a licensed NYS land surveyor
> * [ ] Review the survey for: encroachments (onto or from adjacent parcels), easement locations, and boundary accuracy
> * [ ] Compare survey findings to the title commitment exceptions
> * [ ] Identify any discrepancy between deed description and physical survey

> **Phase 4 — Defect Resolution**
>
> * [ ] For each identified title defect, determine the resolution path (see matrix below)
> * [ ] Confirm that all Schedule B-1 requirements are satisfied before the closing date
> * [ ] Obtain the title company's commitment to issue the owner's policy at closing with any agreed exceptions removed

Title Defect Resolution Matrix [#title-defect-resolution-matrix]

| Defect Type                              | Typical Resolution                                        | Timeline        | Cost Range             |
| ---------------------------------------- | --------------------------------------------------------- | --------------- | ---------------------- |
| Open mortgage (paid off, not discharged) | File satisfaction of mortgage; title company insures over | 2–4 weeks       | $300–$800              |
| Judgment lien against seller             | Satisfy from closing proceeds                             | At closing      | Full judgment amount   |
| Unpaid property taxes                    | Pay from seller's proceeds at closing                     | At closing      | Tax amount + penalties |
| Mechanic's lien                          | Escrow amount or bond; lien release from contractor       | Weeks to months | Variable               |
| Survey encroachment (minor)              | Boundary line agreement with neighbor; title endorsement  | 4–12 weeks      | $1,000–$5,000          |
| Survey encroachment (structural)         | Negotiate price reduction; structural resolution          | Months          | $5,000–$50,000+        |
| Gap in chain of title                    | Quiet title action or affidavit; title insurance bridge   | Weeks to months | $2,000–$10,000+        |
| Estate title issue                       | Probate completion or release from heirs                  | Months          | Variable               |

Boundary Line Agreement Protocol [#boundary-line-agreement-protocol]

When a survey reveals an encroachment that affects a minor portion of the property (e.g., a fence 18 inches over the line), the standard resolution is a boundary line agreement (BLA) — a signed, recorded agreement between the two adjacent property owners that formally adjusts the boundary to reflect the actual physical condition:

1. Both property owners and their attorneys agree on the adjustment
2. A licensed surveyor prepares a corrected survey reflecting the agreed boundary
3. The agreement is signed and recorded in the county clerk's office
4. The title company issues its policy covering the adjusted boundary
5. Timeline: typically 4–12 weeks if both neighbors cooperate

Common Mistakes [#common-mistakes]

**1. Relying on the seller's prior survey rather than commissioning a current one.**
A survey prepared 10 years ago does not reflect improvements or alterations made since — a new driveway, a recently erected fence, or an addition may have created encroachments that did not exist at the time of the old survey.

**2. Accepting the survey exception in the title policy without understanding what it excludes.**
The survey exception removes a major category of risk from coverage — encroachments and boundary disputes that a current survey would reveal. For any property where boundary precision matters, removing the survey exception through a current survey and endorsement is warranted.

**3. Not searching for judgment liens against the seller in all counties where the seller has owned property.**
Judgments are docketed in the county where entered. If the seller has owned property in multiple counties, each county must be searched. A judgment in the wrong county that was missed in the search can attach to the property and survive transfer.

**4. Not confirming property tax arrears before closing.**
Property taxes that are delinquent for multiple years can accumulate into significant liabilities. The closing statement should itemize and satisfy all outstanding property tax obligations from the seller's proceeds.

**5. Closing on a property with an unresolved mechanic's lien.**
A mechanic's lien that is not satisfied at closing survives the transfer and becomes the buyer's problem. Never close with an open mechanic's lien without a formal lien release, a court order discharging the lien, or an escrow holdback sufficient to cover the lien amount.

**6. Not reviewing Schedule B-2 exceptions to understand what the title policy does not cover.**
Schedule B-2 lists items that the title company has identified and specifically excluded from coverage. Each exclusion represents an accepted risk. Buyers who do not read and understand Schedule B-2 may be surprised when a claim arises that falls within an accepted exception.

Key Takeaway [#key-takeaway]

Title defects in New York State are identified through the title search and revealed through a current survey — two distinct and complementary processes that must both be completed before closing. Survey encroachments, open liens, judgment attachments, and chain-of-title gaps are all resolvable before closing when identified early enough. The title review checklist, combined with a commission of a current survey and removal of the survey exception, converts these risks from post-closing surprises into pre-closing negotiations.
