How to verify lot lines

Reader Question: ​We want to know how to verify lot lines. We have found a home we want to buy. Our agent is not the listing agent. The lot corners were described based on the location of flower beds, shrubbery, trees on the lot, and the adjacent neighbor’s landscaping location. The datasheet stated the lot’s depth and width, but the agent did not have a tape measure. Neither the owner of the home nor the listing agent was present. It was the first time our agent had ever seen the house. We are planning at some future point in time, a swimming pool. Our agent was very comfortable with her observations, but we wonder, what if she is wrong? We don’t want to offend her. How can we verify the lot size?

​Monty’s Answer: While your agent may be correct, this is not a situation to worry about offending the agent. Knowing how to verify lot lines is one of the basic due-diligence facts to uncover before buying a home. Guesstimates will not count if there is a disagreement in the future. Here is an article at about what can happen when there is confusion over lot boundaries.

The property survey

At some point in the past, there was a survey of the property. At that time, the surveyor marked the lot corners with metal stakes. Over time, these corner markers can disappear. Some examples of how this happens are; grading the lot, adding soil, removal of the stake by accident, or moved on purpose.

A quick story

I recently helped a relative find their stakes with a metal detector. Two of the stakes were almost two feet underground. Were they found in the proper location? The only way to verify the stakes are accurate is to engage a licensed surveyor. A licensed surveyor and the location of the property can affect the cost to locate the stakes. A survey may range in price from $200.00 to over $1,000. It pays to seek two or three estimates. The question of who should pay for it is often a negotiation between the buyer and the owner.

Your choices

  1. Ask your agent to deliver the survey of the property to you. If they find the original document, this may be a satisfactory solution. With the survey and a tape measure, or a metal detector, one may find the stakes. Common sense and experience now come into play as one uses judgment to decide whether the stakes appear correct. The risk is something, or somebody moved the original stakes.
  2. If no survey can be located (check the tax listing department in the Register of Deeds office), the county or the municipality has online GIS systems. Many GIS systems can activate a layer to identify the lot lines.
  3. If all else fails, the last and most reliable source of verifying the corner stakes is the registered land surveyor. They will confirm or reestablish the correct location of the boundaries. You can deploy this process as a condition in a purchase agreement.
