Boundary Disputes 101: What to Do When a Neighbor’s Fence or Structure Crosses the Line

Few things create tension between neighbors faster than a disagreement over where one property ends and the next begins. Maybe a fence was built a few feet onto your side of the line. Maybe a shed, driveway, or hedge has quietly crept across the boundary over the years. Whatever the cause, a property line dispute can turn a simple misunderstanding into a costly, stressful conflict if it isn’t handled correctly from the start.

Here’s what property owners in Mobile and Baldwin County need to know about identifying, documenting, and resolving a boundary dispute the right way.

What Actually Counts as a Boundary Dispute?

A boundary dispute happens any time there’s disagreement about the true legal location of a property line. This can involve:

• A fence, wall, or hedge built on the wrong side of the line
• A shed, garage, pool, or addition that encroaches onto a neighboring lot
• Overlapping legal descriptions from old or inaccurate deeds
• Driveways or shared access paths that cross onto another owner’s land
• Disagreements after a fence has been in the “wrong” spot for years or decades

In many of these cases, neither neighbor is acting in bad faith. Older surveys, outdated deed descriptions, and structures built before either owner purchased the property are common culprits along the Gulf Coast, where land has often changed hands multiple times over the last century.

Why You Can’t Resolve This by “Eyeballing” the Line

It’s tempting to settle a boundary disagreement by looking at an old fence, a line of trees, or what the previous owner told you. Unfortunately, none of these hold up as legal evidence of where a property line actually sits. Deeds describe boundaries using bearings, distances, and monuments that must be located and verified in the field by a licensed surveyor — not estimated from visual landmarks.

Relying on assumptions instead of a professional boundary survey is one of the most common ways small disagreements escalate into legal disputes, especially once a sale, refinance, or new construction project is on the table.

How a Boundary Survey Resolves the Issue

A licensed surveyor resolves a property line dispute by:

• Researching the recorded deeds, plats, and legal descriptions for both properties
• Locating existing monuments, pins, or markers in the field
• Measuring and mapping the true boundary based on the legal description
• Identifying any encroachments, gaps, or overlaps between the properties
• Producing a signed, sealed survey that can be used as evidence if the dispute needs to go further

Once the survey is complete, you have an objective, legally defensible answer to where the line actually falls — which removes guesswork and emotion from the conversation with your neighbor.

What Happens After the Survey

In most cases, a completed boundary survey is enough to resolve the disagreement informally. Once both parties can see exactly where the line sits, encroachments are often corrected voluntarily — a fence gets moved, a shed gets relocated, or the neighbors agree on a solution like a boundary line agreement recorded with the county.

If the survey reveals a more significant encroachment, or if the neighbor disputes the findings, the survey still serves as the foundation for any next step, including mediation or legal action. Courts and attorneys rely on licensed survey data, not verbal agreements or assumptions, when boundary disputes need to be settled formally.

Surveyor or Attorney? Who to Call First

Start with a surveyor. A licensed surveyor can determine the facts on the ground — where the line legally sits and whether an encroachment actually exists. This is almost always the first step, even if you eventually need an attorney.

You’ll want to involve an attorney if:

• The neighbor disputes or refuses to acknowledge the survey findings
• The encroachment involves a permanent structure that’s expensive to move
• You need a formal boundary line agreement recorded with the county
• The dispute affects a pending sale, refinance, or estate transfer

Many boundary disputes never reach this stage. Getting accurate survey data early is usually what keeps them from getting there.
