What Happens When an ALTA Survey Reveals Gaps and Overlaps?
An alta survey can find something unexpected. Sometimes, a strip of land does not belong to either neighbor on paper. Other times, two neighbors both seem to own the same piece of ground. These problems are called gaps and overlaps. For developers, knowing what they mean and what to do next can save a deal.
What Surveyors Mean by Gaps and Overlaps
Not every boundary problem looks the same.
A gap is a strip of land that neither neighbor’s deed covers. When you compare the two deeds side by side, that strip is missing from both.
An overlap is the opposite. Two deeds both describe the same piece of land. On paper, two owners seem to own the same ground.
These are not encroachments. An encroachment is when a fence or building crosses into someone else’s yard. Gaps and overlaps live in the paperwork, not on the ground.
During an alta survey, the surveyor compares deeds, recorded maps, and field measurements. When those sources do not match, gaps and overlaps show up.
Why Gaps and Overlaps Often Trace Back to Old Surveying Methods
Most of these problems are not new. They have been hiding in the records for a long time.
Old surveys used older tools. Compasses had errors. Chains stretched. Surveyors started from different points and used different markers.
Over time, different surveyors worked the same land using different evidence. Each one recorded what they found at the time. When a modern survey stacks all those old records on top of each other, they do not always line up.
Old deeds also used vague descriptions. Later maps used new systems. Small errors built up over years of sales and re-surveys.
By the time an alta survey reviews the full history, those small differences can show up as a gap or overlap between parcels that nobody noticed for decades.
How Surveyors Look at Conflicting Evidence
Finding a gap or overlap is just the starting point.
Surveyors first read through deeds, plats, and recorded documents. They look at the legal descriptions for the property and the neighboring lots. They trace where each description came from.
Then they go to the field. They look for old iron pins, stone walls, and other markers that show where lines were actually set. In Connecticut, physical markers on the ground carry a lot of weight.
They compare the records to what they find in the field. Fences, old occupation lines, and structures can add more clues. Sometimes the field evidence and the written records point in different directions.
A licensed surveyor weighs all of it and decides where the boundary most likely sits. That conclusion becomes part of the alta survey.
Why a Gap or Overlap Does Not Always Mean a Fight
A gap or overlap on a survey map is not always a big legal problem.
There is a difference between a mistake in old paperwork and a real dispute between neighbors. Many gaps and overlaps sit quietly in the record for years. Neighbors often agree on where the line is in practice, even if the deeds do not match perfectly.
More research is usually needed before anyone draws conclusions. The surveyor notes the problem. Then title attorneys look at whether it creates a real ownership question or whether Connecticut law already resolves it.
Not knowing exactly what the records say is not the same as two people fighting over the land. Many deals move forward after a careful review shows the gap or overlap does not affect the planned use.
How These Findings Can Change a Deal
When a gap or overlap turns up, the people involved need to figure out the next step.
More title review usually comes first. The title company and attorneys look at whether the problem affects ownership coverage. They may ask for more research on the neighboring deeds.
Some fixes require paperwork. A boundary line agreement between neighbors, a corrective deed, or a lot line adjustment can sometimes solve the issue. These steps take time and need cooperation from the other side.
Project plans may need to shift. If the gap or overlap is in an area that matters for the project, it can affect setback lines, lot coverage, or utility work. Developers need to know the full picture before locking in site plans.
Finding it early is the whole point. Due diligence exists so problems surface before closing, not after. A gap or overlap found during the review period is a manageable problem. The same problem found after closing is a much harder one.
In Connecticut, land records run long and property histories run deep. These findings come up more than people expect. But they are not deal-killers when they are handled early with the right team involved.
