When your land title, a relocation survey, and the old fence or concrete “mohon” do not line up, the dispute is usually not solved by asking who has been using the land longer. In the Philippines, the practical question is: what exact parcel is legally covered by the title, how was it surveyed and described, and where should those technical boundaries fall on the ground? This article explains how Philippine boundary disputes are handled when the title, survey plan, and physical markers appear to contradict one another, what documents matter, what offices may be involved, and what remedies are available if the neighbor refuses to cooperate.

Why Land Titles, Surveys, and Physical Markers Sometimes Do Not Match

Boundary disputes are common in the Philippines because land records, physical occupation, and actual use often develop at different speeds.

A titled lot may have been surveyed decades ago. Its concrete monuments may have been buried, destroyed, moved, or covered by roads, fences, trees, walls, or later construction. In rural areas, families may rely on old “known boundaries” such as coconut trees, ditches, creeks, or footpaths. In subdivisions, homeowners sometimes build fences based on developer stakes or informal measurements, not on the approved technical description.

The usual causes include:

Missing or moved monuments such as concrete mohon, stakes, or boundary stones
Old fences built for convenience, not along the true legal boundary
Errors in old surveys or technical descriptions
Overlapping titles or overlapping survey plans
Subdivisions done without properly relocating corners on the ground
Encroachments by walls, houses, septic tanks, eaves, driveways, or farm improvements
Reliance on tax declarations or assessor maps, which are not the same as Torrens titles
Natural changes, such as erosion, accretion, or changes in waterways
Occupation by relatives or neighbors for many years without formal correction of title

A physical marker is important evidence, but it is not automatically the law. A Torrens title is also very strong evidence of ownership, but the title must still identify the land correctly. The Supreme Court has emphasized that a certificate of title is evidence of ownership, but registration itself is not a mode of acquiring ownership; the survey and technical description are essential in identifying the exact property covered by the title. (Supreme Court E-Library)

What Usually Controls: Title, Survey, or Physical Markers?

There is no one-sentence answer that works for every case. In practice, Philippine courts and land offices look at the complete chain of land identity:

The Torrens title or original source of ownership
The technical description stated in or attached to the title
The approved survey plan from which the technical description came
The relocation survey done by a licensed geodetic engineer
The physical monuments and actual occupation on the land
The history of possession, construction, fencing, deeds, tax declarations, and adjoining owners’ records

The Title Is the Starting Point, Not the Whole Answer

For registered land, the title is very important because registered land is generally protected against acquisition by prescription or adverse possession. Under Presidential Decree No. 1529, also known as the Property Registration Decree, registered land is not subject to prescription, and a certificate of title cannot be collaterally attacked; it can be altered, modified, or cancelled only in a direct proceeding allowed by law. (Supreme Court E-Library)

This means a neighbor generally cannot defeat your Torrens title simply by saying, “We have used that strip for 30 years.”

But if the real problem is that the title’s technical description overlaps with another title, or the title mistakenly includes land that should not have been included, the issue must be resolved through proper survey verification and, if necessary, a direct court proceeding.

The Survey Identifies Where the Title Falls on the Ground

A survey does not create ownership by itself. Its function is to locate and identify the land described in the title.

In boundary disputes, a simple sketch or private estimate is usually not enough. Courts often need a reliable relocation or verification survey using the bearings, distances, corners, and approved survey data in the title or government records. In Heirs of Pabaus v. Heirs of Yutiamco, the Supreme Court explained that overlapping or encroachment issues require reliable verification surveys, and that courts may need technical assistance from government surveyors from the LRA or DENR. (Supreme Court E-Library)

A relocation survey is especially important when:

The mohon is missing
The old fence does not match the title
Two titles overlap
A structure appears to encroach
The lot area on the ground differs from the title area
The adjoining owner refuses to recognize the boundary

Physical Markers Are Evidence, But They Can Be Wrong

Concrete monuments, fences, walls, hedges, ditches, and trees can help prove how people treated the boundary. But they are not conclusive if they do not match the approved survey and technical description.

A fence may have been built inside the owner’s land for convenience. A wall may have been built slightly outside the true boundary by mistake. A mohon may have been moved by a previous owner, contractor, or neighbor. That is why boundary disputes should not be resolved by simply “following the old fence” unless the technical records support it.

Area Is Usually Less Important Than Boundaries

A common mistake is to focus only on square meters. For example, the title says 500 square meters, but the relocation survey shows 492 square meters. Or the title says 1,000 square meters, but the fence encloses 1,030 square meters.

In Philippine land law, the exact identity of the land is normally controlled more by metes and bounds—the bearings, distances, and boundaries in the technical description—than by the numerical area alone. The Supreme Court has recognized that what defines titled property is not merely the stated area, but the boundaries and technical description. (Supreme Court E-Library)

Legal Basis for Resolving Boundary Disputes in the Philippines

Civil Code Rights of the Landowner

The Civil Code protects an owner’s right to enjoy, recover, and protect property. Article 428 gives the owner the right to enjoy and dispose of property and to recover it from unlawful possession. Article 430 also allows an owner to enclose land by walls, ditches, hedges, or other means, subject to easements and other legal limitations. (LawPhil)

However, the Civil Code also requires the true owner to use lawful remedies. Article 433 states that actual possession under claim of ownership raises a disputable presumption of ownership, and the true owner must resort to judicial process if the possessor refuses to surrender the property. Article 434 adds an important rule in recovery cases: the property must be properly identified, and the plaintiff must rely on the strength of his or her own title. (LawPhil)

In simple terms: you must prove both ownership and the exact land being claimed.

Torrens Title Rules Under PD 1529

For registered land, PD 1529 provides the framework for registration, amendment of certificates of title, and registration of court judgments affecting land. A title cannot simply be changed because one owner obtained a new private survey. Amendments or corrections affecting the certificate of title generally require proper proceedings, notice to interested parties, and court approval when required by law. (Supreme Court E-Library)

This is why a relocation survey may help prove the correct boundary, but it does not automatically change the title at the Registry of Deeds.

Boundary Disputes Are Often Not Proper Ejectment Cases

Some owners immediately file a forcible entry or unlawful detainer case when a neighbor occupies a disputed strip of land. That may work if the issue is simple possession. But if the real issue is the correct metes and bounds of the titled property, ejectment may be the wrong remedy.

In Martinez v. Heirs of Lim, the Supreme Court held that a boundary dispute involving actual metes and bounds could not be properly resolved in a summary forcible entry case and was more appropriate for an action involving ownership and recovery of property. (Supreme Court E-Library)

This matters because filing the wrong case can waste time and money.

Barangay Conciliation May Be Required First

Under the Katarungang Pambarangay system in the Local Government Code, many disputes between individuals who live in the same city or municipality must first go through barangay conciliation before they can be filed in court. For disputes involving real property, venue is generally the barangay where the property or the larger portion of it is located. (Supreme Court E-Library)

If barangay conciliation applies, the case may be dismissed or delayed if there is no proper Certificate to File Action. The law also provides exceptions, such as cases involving the government, offenses punishable by imprisonment exceeding one year or fine exceeding ₱5,000, urgent provisional remedies, or disputes between parties from different cities or municipalities where barangay jurisdiction does not apply. (Supreme Court E-Library)

Moving Boundary Markers Can Be a Criminal Issue

Do not move a mohon, boundary stone, or survey monument just because you believe it is wrong. Article 313 of the Revised Penal Code, as amended by Republic Act No. 10951, penalizes altering boundary marks or monuments of towns, provinces, estates, or other marks intended to designate boundaries. (Supreme Court E-Library)

If a marker is missing or appears to have been moved, document it and have the boundary professionally relocated by a licensed geodetic engineer.

Step-by-Step Guide to Resolving a Land Boundary Dispute

1. Stop Construction or Boundary Changes First

Before building a fence, demolishing a wall, cutting trees, or moving a mohon, pause and preserve evidence.

Take clear photos and videos showing:

The existing fence, wall, marker, or structure
The location of visible mohon or stakes
Any encroaching structure
Nearby roads, canals, posts, or landmarks
The date the photos were taken
Any recent construction activity by the neighbor

Avoid self-help measures that may create a criminal complaint, damage claim, or request for injunction.

2. Gather the Land Records

Collect documents for both your lot and, if available, the adjoining lot. The most useful records are:

Document	Where to Get It	Why It Matters
Certified True Copy of title	Registry of Deeds or LRA eSerbisyo	Confirms the registered owner, title number, lot number, and technical description
Owner’s duplicate certificate of title	Owner’s records	Needed for many registration transactions
Approved survey plan	LRA, DENR-LMS, LMB, Registry of Deeds, or surveyor’s records	Shows the official lot configuration
Technical description	Title, survey plan, LRA/DENR records	Provides bearings, distances, corners, and area
Tax declaration	City or municipal assessor	Useful supporting evidence, but not conclusive proof of ownership
Real property tax receipts	City or municipal treasurer	Shows tax payments and property identification
Deed of sale, donation, partition, or extrajudicial settlement	Owner’s records, notarial archives, Registry of Deeds	Shows how ownership was transferred
Old subdivision plan or developer plan	Developer, HOA, LRA, DENR, city planning office	Important in subdivision boundary issues
Photos, videos, affidavits	Owner, neighbors, barangay records	Helps show possession, construction, and changes over time

The LRA provides online services for requesting Certified True Copies of titles through eSerbisyo, while registration transactions commonly require instruments such as the deed, tax declaration, and owner’s duplicate title depending on the transaction. (eserbisyo.lra.gov.ph) (Land Registration Authority)

3. Hire a Licensed Geodetic Engineer for a Relocation Survey

A relocation survey is the practical heart of most boundary disputes. It attempts to locate on the ground the corners and boundaries described in the title and approved plan.

Use a licensed geodetic engineer. The practice of geodetic engineering is regulated under Republic Act No. 8560, the Philippine Geodetic Engineering Act of 1998. (LawPhil)

A proper relocation survey usually involves:

Reviewing the title and technical description
Obtaining or checking the approved survey plan
Locating existing monuments and reference points
Measuring the property on the ground
Comparing field results with the title and plan
Preparing a relocation plan, sketch, or technical report
Identifying encroachments, overlaps, or missing monuments

For best results, invite the adjoining owner or occupant to attend the survey. Their presence is not always legally required for a private survey, but it helps avoid accusations that the survey was done secretly or unfairly.

4. Compare the Title, Approved Plan, Survey, and Occupation

After the relocation survey, ask the geodetic engineer to explain the findings in practical terms:

Does the title close mathematically?
Are the bearings and distances consistent?
Were the original monuments found?
If monuments were missing, what reference points were used?
Is the fence inside or outside the titled boundary?
How many square meters are affected?
Is there an overlap with the adjoining title?
Is the issue a simple encroachment, a survey error, or a title conflict?

A survey report that clearly answers these questions is far more useful than a sketch that merely draws a line.

5. Try a Written Boundary Settlement if the Dispute Is Simple

If the problem is a small fence error or minor encroachment, the parties may be able to settle without a full court case.

Possible settlement options include:

Agreeing to move the fence to the surveyed boundary
Allowing a temporary use arrangement
Creating or recognizing an easement
Selling or transferring a small strip, if legally allowed
Executing a boundary agreement, compromise agreement, or deed
Preparing a subdivision plan if part of the land will be transferred

Put any settlement in writing. If the settlement affects registered land, it may require notarized documents, tax payments, an approved subdivision plan, and registration with the Registry of Deeds before it becomes effective against third persons.

6. Go Through Barangay Conciliation When Required

If both parties are individuals covered by the Katarungang Pambarangay rules, file a complaint with the proper barangay before going to court.

A typical barangay process looks like this:

File the complaint with the barangay where the property or larger portion is located.
The Punong Barangay summons the respondent.
The Punong Barangay attempts mediation.
If mediation fails, the dispute may be referred to a Pangkat.
If settlement fails, the barangay issues a Certificate to File Action.

The Local Government Code provides specific timing rules. Mediation is generally initiated promptly, and if no settlement is reached within the prescribed periods, the matter may proceed to the Pangkat or eventually to court. The law also provides that barangay settlement has the force and effect of a final judgment after the lapse of the period to repudiate it. (Supreme Court E-Library)

A barangay settlement may be enforced by the Lupon within six months; after that, enforcement may be through the proper court. (Supreme Court E-Library)

7. Use DENR, LRA, or Registry Records When Technical Verification Is Needed

If the issue involves overlapping surveys, missing plans, or uncertainty in technical descriptions, the relevant records may be with:

LRA for registered titles, decrees, and subdivision or consolidation plans of titled lands
Registry of Deeds for title records and registered instruments
DENR-LMS or regional survey offices for land survey records and public land survey data
Land Management Bureau for land records and survey-related information
City or municipal assessor for tax mapping and declarations

The DENR’s land records systems and survey approval rules are designed to support the processing, verification, and management of land survey records, cadastral maps, isolated survey plans, public land applications, patents, and titles. (Supreme Court E-Library) (Supreme Court E-Library)

For old or difficult cases, the bottleneck is often not the law but the records: missing plans, illegible technical descriptions, destroyed monuments, unintegrated cadastral data, or conflicting records from different agencies.

8. File the Correct Court Case if Settlement Fails

If the neighbor refuses to respect the verified boundary, or if there are overlapping titles, the dispute may need a court case.

Possible remedies include:

Situation	Possible Remedy
Neighbor occupies part of your titled land	Accion reivindicatoria, or action to recover ownership and possession
Neighbor has possession but ownership is also disputed	Accion publiciana or accion reivindicatoria, depending on the facts
There is a cloud on your title or an adverse claim	Action to quiet title
Two titles overlap	Action for reconveyance, cancellation, correction, or other direct proceeding
Wrong technical description in title	Petition for amendment or correction under the proper procedure
Ongoing construction threatens the boundary	Injunction or other provisional remedy, if legally justified
Structure was built over the boundary	Civil Code remedies on builders in good faith or bad faith

The Civil Code allows an action to quiet title when there is a cloud on title, and the plaintiff must have legal or equitable title or interest in the property. (LawPhil)

Jurisdiction depends partly on the assessed value of the property. Under Republic Act No. 11576, first-level courts generally handle civil actions involving title to, possession of, or interest in real property when the assessed value does not exceed ₱400,000, while the Regional Trial Court handles those exceeding that threshold, subject to specific rules and exceptions. (Supreme Court E-Library)

9. Register the Final Judgment, Order, or Settlement

A court judgment, compromise agreement, or order affecting registered land should not remain only in a folder. If it changes ownership, boundaries, title details, or registered interests, it must be brought to the proper Registry of Deeds and processed according to land registration rules.

PD 1529 allows judgments and orders affecting registered land to be registered, and amendments to certificates of title must follow the proper legal procedure. (Supreme Court E-Library) (Supreme Court E-Library)

Common Boundary Dispute Scenarios in the Philippines

Scenario	What It Usually Means	Practical Approach
The old fence is not aligned with the title	The fence may have been built for convenience or by mistake	Get a relocation survey; negotiate or file the proper case if the neighbor refuses
The mohon is missing	The original monument may have been destroyed, buried, or moved	Do not replace it yourself; have a licensed geodetic engineer relocate the corner
The neighbor’s wall crosses the boundary	Possible encroachment or good-faith building issue	Survey first; then apply Civil Code rules on builders and landowners
Two Torrens titles overlap	Serious title and survey conflict	Obtain certified records, conduct verification survey, and file a direct court action if unresolved
The title area and actual area differ	Area may be secondary to metes and bounds	Check technical description and approved plan; correct title only through proper proceedings
Tax declaration shows a different boundary	Tax records may be inaccurate or only for assessment	Use tax records as supporting evidence, not as final boundary proof
The neighbor says “we have occupied this for decades”	Long possession alone usually does not defeat registered land	Verify title and boundary; use barangay or court remedy
A subdivision lot is smaller than represented	Could involve developer layout, road widening, easements, or plan issues	Check approved subdivision plan, title, restrictions, and agency records
A foreigner is involved	Land ownership restrictions may affect settlement options	Check constitutional restrictions before any transfer or sale of land

What If a Neighbor Built on the Wrong Side of the Boundary?

Encroachments are emotionally difficult because they often involve expensive structures: a house wall, garage, septic tank, fence, balcony, roof eaves, or commercial improvement.

The Civil Code has specific rules for buildings, planting, and sowing on another person’s land. Article 448 gives the landowner options when a builder acted in good faith, including appropriating the improvement after paying indemnity or requiring the builder to buy the land, subject to limits where the land value is considerably more than the improvement. If the builder acted in bad faith, Articles 449 and 450 provide harsher consequences, including loss of what was built without indemnity and possible demolition or restoration at the builder’s expense. (LawPhil)

In real life, the key issue is often good faith. A neighbor who relied on a developer’s old marker may claim good faith. A neighbor who built after receiving a survey report or written objection may have a harder time making that argument.

Before demanding demolition, identify:

The exact encroached area
Whether the structure is permanent or removable
Whether the builder knew of the true boundary
Whether the owner objected promptly
Whether there was an old agreement, tolerance, or easement
Whether demolition would be disproportionate or unsafe

Special Issues for OFWs, Foreigners, and Filipinos Abroad

Boundary disputes are harder when the owner is abroad. The usual practical solution is to appoint a trusted representative in the Philippines through a Special Power of Attorney.

For documents executed abroad, Philippine offices may require consular acknowledgment, notarization, apostille, or other authentication depending on the country where the document is signed and the receiving office’s requirements. The Philippines has used the Apostille system for documents covered by the Apostille Convention since 2019, replacing the old “red ribbon” process for many public documents used between contracting countries. (Philippine Embassy in Berne)

Foreigners should also be careful with settlement structures. The 1987 Constitution generally prohibits transfer or conveyance of private land to persons who are not qualified to acquire land, subject to specific exceptions such as hereditary succession. It also provides rules for natural-born Filipinos who lost Philippine citizenship and later acquire private land subject to legal limitations. (LawPhil)

This matters because a foreign neighbor may be able to settle possession, easement, lease, damages, or removal issues, but may not be legally allowed to acquire a strip of private land by sale if the transaction violates Philippine land ownership restrictions.

Required Documents and Evidence Checklist

For a serious boundary dispute, prepare a file with the following:

Land and Title Documents

Certified True Copy of your title
Certified True Copy of the adjoining title, if available
Owner’s duplicate certificate of title
Technical description
Approved survey plan
Subdivision or consolidation plan, if applicable
Deed of sale, donation, partition, extrajudicial settlement, or other source document
Tax declaration and real property tax receipts

Survey and Technical Evidence

Relocation survey report
Sketch plan showing existing fence, structures, and true boundary
Coordinates, bearings, and distances used by the geodetic engineer
Photos of monuments, stakes, walls, roads, and structures
Written explanation from the geodetic engineer
Certified copies of relevant DENR, LMB, LRA, or Registry records

Possession and Dispute Evidence

Photos and videos with dates
Barangay blotter or complaint
Demand letters and replies
Affidavits of neighbors or previous owners
Construction permits or fencing permits, if relevant
Receipts for fencing, clearing, or improvements
Barangay settlement or Certificate to File Action

If the Owner Is Abroad

Special Power of Attorney
Valid government IDs of owner and representative
Proof of authority to receive notices and sign documents
Apostille, consular acknowledgment, or authentication required by the receiving office
Clear written instructions to the representative

Typical Timelines and Bottlenecks

Step	Typical Timeline	Common Bottlenecks
Getting Certified True Copy of title	Several days, depending on RD/LRA service and delivery	Wrong title number, non-computerized records, name mismatch
Private relocation survey	A few days to several weeks	Missing monuments, difficult terrain, uncooperative occupants, unavailable plans
Barangay conciliation	Usually weeks, depending on attendance and settlement efforts	Non-appearance, heated family disputes, unclear property documents
DENR/LRA record verification	Varies widely by office and record condition	Old surveys, missing plans, technical discrepancies, backlog
Court case	Often months to years	Need for expert survey, injunction issues, appeals, overlapping titles
Registration of judgment or correction	Varies by RD and completeness of requirements	Missing owner’s duplicate, tax clearance, unclear dispositive portion

The most common delay is incomplete technical evidence. A boundary case can become unnecessarily expensive when the parties file in court before obtaining the title, approved plan, and a competent relocation survey.

Mistakes to Avoid

Treating the Fence as the Automatic Boundary

An old fence is evidence, not automatic ownership. It may be correct, but it must be checked against the title and approved survey.

Moving or Destroying the Mohon

Even if you believe the marker is wrong, moving it can create legal and criminal problems. Have the corner relocated by a licensed geodetic engineer.

Filing the Wrong Case

If the dispute is really about the metes and bounds of titled property, a summary ejectment case may not resolve it. The Supreme Court has warned that true boundary disputes may require a full action involving ownership and recovery, not a quick possession case. (Supreme Court E-Library)

Relying Only on Tax Declarations

Tax declarations are useful supporting evidence, but they do not establish the exact Torrens title boundary. Courts usually require stronger proof, especially the title, technical description, approved plan, and reliable survey.

Ignoring Easements and Roads

A titled boundary does not always mean the owner can block everything. Easements, road rights-of-way, drainage, subdivision restrictions, and government road widening may affect actual use.

Making an Oral Settlement Only

Boundary agreements should be written, signed, notarized when appropriate, and registered if they affect titled land. Oral understandings often fail when the property is sold, inherited, or mortgaged.

Building First, Surveying Later

Many disputes become worse because someone builds a fence or wall before a relocation survey. Survey first. Build later.

Frequently Asked Questions

Which prevails: the land title, the survey, or the fence?

The title and its technical description are the starting point, but the approved survey and reliable relocation survey are needed to locate the titled land on the ground. The fence is evidence of occupation, but it does not automatically prevail if it conflicts with the title and approved survey.

What if my title says 500 square meters but the actual survey shows less?

A small difference in area does not automatically mean the title is invalid. The more important question is whether the bearings, distances, and boundaries match the approved plan. In many cases, metes and bounds are more important than the stated area alone. (Supreme Court E-Library)

Can my neighbor acquire part of my titled land by using it for many years?

For registered land, mere long possession generally does not defeat the Torrens title because registered land is not subject to prescription. However, the exact boundary must still be proven through the title, approved plan, and proper survey evidence. (Supreme Court E-Library)

Can I remove my neighbor’s fence if it is inside my titled property?

Do not remove it immediately without proper documentation and legal process. First get a relocation survey, document the encroachment, send a written demand if appropriate, go through barangay conciliation when required, and use the correct court remedy if the neighbor refuses.

Is barangay conciliation required for land boundary disputes?

Often, yes, if the parties are individuals covered by the Katarungang Pambarangay rules and the property is within the barangay’s venue rules. There are exceptions, including disputes involving parties from different cities or municipalities in certain cases, disputes involving the government, and situations requiring urgent provisional remedies. (Supreme Court E-Library) (Supreme Court E-Library)

What if both owners have Torrens titles that overlap?

An overlap between Torrens titles is a serious technical and legal issue. The usual approach is to obtain certified title and survey records, conduct a verification or relocation survey, and, if not resolved, file a direct court proceeding for cancellation, correction, reconveyance, or other proper relief. A title cannot be collaterally attacked. (Supreme Court E-Library)

Can a private geodetic engineer decide the final boundary?

A private geodetic engineer can provide crucial technical evidence, but the survey alone does not amend a Torrens title or bind a resisting neighbor in all cases. If the dispute continues, the court may evaluate the survey, require government verification, or appoint technical assistance.

What if the mohon was moved?

Document the condition immediately with photos and witnesses. Do not move it again. Have a licensed geodetic engineer relocate the corners based on approved records. Altering boundary marks can have criminal consequences under Article 313 of the Revised Penal Code, as amended. (Supreme Court E-Library)

Can I correct a wrong technical description in my title?

Possibly, but it must be done through the proper procedure. Under PD 1529, a certificate of title cannot simply be erased, altered, or amended after entry except through the process allowed by law, often requiring a court order and notice to affected parties. (Supreme Court E-Library)

Can a foreigner settle a Philippine boundary dispute?

Yes, a foreigner may participate in resolving a dispute involving possession, encroachment, lease rights, inheritance issues, or improvements. But a foreigner generally cannot acquire private Philippine land by sale or transfer unless an exception applies, such as hereditary succession. Settlement terms must respect constitutional land ownership restrictions. (LawPhil)

Key Takeaways

A boundary dispute is solved by identifying the exact land covered by the title, not by guessing from fences or old markers.
The strongest evidence usually includes the Torrens title, technical description, approved survey plan, and a competent relocation survey.
Physical markers like mohon, walls, and fences are important evidence, but they can be wrong, missing, or moved.
Do not move boundary monuments or demolish structures without proper documentation and legal process.
Barangay conciliation is often required before filing in court, unless an exception applies.
If the dispute involves overlapping titles, wrong technical descriptions, or serious encroachment, a direct court proceeding may be necessary.
A private survey helps prove the boundary, but it does not automatically amend a title or resolve a contested overlap.
For registered land, long possession by a neighbor usually does not defeat the title, but the owner must still prove the exact property being claimed.
Written settlements affecting titled land should be properly documented, notarized when required, and registered with the Registry of Deeds if they affect ownership, boundaries, or real rights.
