What Is a Boundary Line Agreement in NH Real Estate?

🏡 What Is a Boundary Line Agreement in NH Real Estate?

Boundary issues are common in New Hampshire, especially in older towns like Plymouth, Campton, Rumney, Thornton, and Ashland, where property lines were established decades — or even centuries — ago.

When a property line is unclear, disputed, or needs to be adjusted, a boundary line agreement may be used to legally confirm or modify the line between two neighboring properties.

Here’s what NH buyers should know.

⭐ What Is a Boundary Line Agreement?

A boundary line agreement is a legally recorded document between two neighboring property owners that establishes, clarifies, or adjusts the exact location of a shared property line.

These agreements are often used to:

✔ Resolve boundary disputes

✔ Correct inaccurate old surveys

✔ Finalize agreed-upon property line adjustments

✔ Clarify ownership of driveways, fences, or structures near the line

✔ Clean up title issues before a sale

⭐ When Are Boundary Line Agreements Used in NH?

Common situations include:

✔ A fence or shed was built near or over the line

✔ Two surveys show different boundary locations

✔ A driveway sits on or close to the neighbor’s land

✔ A structure encroaches near the property line

✔ A seller wants to avoid a title problem before listing

✔ A buyer’s lender requires clarification of the lot line

Boundary line agreements are often the simplest solution when neighbors want to avoid litigation.

⭐ How Boundary Line Agreements Work

A typical NH boundary line agreement includes:

• The agreed-upon boundary description

• A survey or sketch prepared by a licensed surveyor

• Signatures of both property owners

• Notarization

• Recording at the county Registry of Deeds

Once recorded, the new boundary becomes legally binding and stays with both properties permanently.

⭐ Why These Agreements Matter for NH Buyers

Boundary line agreements help:

✔ Prevent future disputes

✔ Resolve title issues

✔ Provide clear legal boundaries

✔ Ensure lenders approve the property

✔ Clarify land ownership before closing

✔ Confirm driveway or structure placement is legal

In rural parts of NH, where lot lines aren’t always perfectly marked, these agreements can be crucial.

⭐ Do Boundary Line Agreements Change Property Size?

Sometimes — but not always.

If the agreement relocates the line, each parcel may gain or lose a small amount of land.

If the agreement simply clarifies an already accepted line, lot sizes usually remain the same.

Your closing attorney or surveyor can verify any changes.
