Buying several parcels at once sounds simple. Then the records stop lining up. One deed points to a boundary that does not quite match the parcel next to it. Another parcel has a legal description that seems to overlap with a neighbor’s land.

A cadastral surveyor exists to sort through this kind of mix-up. Cadastral surveying means setting and confirming property boundaries using legal records. This work matters a lot when many parcels need to work together as one purchase.

If you are putting together several parcels for a project, knowing what a cadastral surveyor checks can help you avoid problems. These problems are much harder to fix after closing.

Matching Each Parcel to Its Recorded Legal Description

Every parcel has a legal description. This is a written record that shows its edges using measurements, directions, and links to nearby land. A cadastral surveyor checks that each parcel in a multi-parcel purchase actually matches its written description.

This matters because legal descriptions written decades apart do not always use the same starting points. Older parcels, especially near the city’s older neighborhoods or along historic roads, sometimes have descriptions written before modern survey rules were in place.

A cadastral surveyor checks these things for each parcel:

• Whether the legal description matches the real conditions on the ground
• Whether recorded measurements match up with each other
• Whether older descriptions point to markers that still exist
• Whether the acreage listed in records matches an actual field measurement

Checking this for every parcel on its own, instead of just assuming they all match, catches problems before they hurt your purchase.

Checking Whether Adjacent Parcels Actually Connect

A multi-parcel purchase often assumes the parcels connect smoothly. This would make one continuous piece of land. A cadastral surveyor checks whether that is actually true.

This is not always the case. Parcels split at different times, sometimes decades apart, can create small gaps or mismatches between edges. These edges were never meant to work together.

Why Adjacency Matters for Development Plans

If your plans depend on parcels connecting cleanly, a gap or overlap between them can affect everything from access to buildable space. Growth has led to more combined parcel purchases for bigger projects. This makes this check more important for buyers combining smaller, older lots.

Things a cadastral surveyor checks include:

• Whether recorded edges of neighboring parcels actually meet
• Whether any strip of unclaimed land sits between parcels
• Whether boundary lines from different surveys use matching starting points
• Whether access between parcels matches what the purchase assumes

Identifying Gaps, Overlaps, and Unresolved Parcel Remnants

Gaps and overlaps show up often in multi-parcel purchases, especially with older or oddly shaped land. A cadastral surveyor points out these issues clearly. This way they can get fixed before the purchase moves forward.

A gap means land between two parcels that belongs to neither one on paper. An overlap means two recorded parcels claim the same ground. Both create real problems for ownership and future building.

Common causes of these issues include:

• Old surveys that used different measuring methods or starting points
• Parcels made through many splits over time without updated surveys
• Small leftover strips of land from earlier land splits
• Boundary descriptions that were never checked against neighboring parcels

Finding these issues before closing gives buyers, sellers, and title companies a chance to fix them. This can happen through extra papers or corrective deeds, instead of finding out after the purchase is done.

Confirming Which Improvements Belong to Each Parcel

When a purchase involves multiple parcels, buildings and other site features do not always sit neatly inside one parcel’s edges. A cadastral surveyor confirms which features belong to which parcel. The surveyor also flags any that cross a boundary line.

This matters for real, practical reasons. A building or fence that sits on two parcels can cause problems with loans, insurance, and future building plans if the parcels ever get sold or split apart.

Features commonly checked during this step:

• Buildings or structures that cross a parcel boundary
• Fencing or paved areas that do not line up with recorded lines
• Utility lines serving more than one parcel
• Shared driveways or access points crossing parcel lines

For buyers planning to later split off or resell single parcels, checking this now avoids problems tied to shared or overlapping features down the road.

Resolving Parcel Record Questions Before Contract Deadlines

Every finding from a cadastral survey needs a clear answer before a multi-parcel purchase moves toward closing. Some issues are small and easy to write down. Others need bigger fixes before the deal can move forward cleanly.

How you fix these issues depends on the specific finding. Rules can differ by county, title company, and lender in the deal. Common fixes include:

• Recording a corrective deed to fix a boundary mismatch
• Getting a boundary line agreement between neighboring owners
• Adjusting the purchase agreement to match real parcel conditions
• Asking the title company to review unresolved gaps or overlaps

If your contract has a firm deadline, fix the issues that affect your main use of the property first. Some findings, like a small description mismatch, may not need to hold up closing. Others, like an unresolved overlap, usually do.
