Confirming what crosses the line
The first step is usually a current survey by a licensed surveyor, compared with the deeds and any earlier surveys of both properties. Surveys sometimes disagree, and the reasons, such as different reference points or old property descriptions, matter in deciding whose line is right. Encroachments vary widely, from an overhanging roof edge or a fence slightly off the line to a driveway or part of a building. New York treats some minor encroachments, such as fences and hedges, differently from structures when someone claims ownership through long use, and the age and nature of the encroachment can shape what claims either side may have. Check your title insurance policy as well, since survey-related coverage varies.
Steps that avoid making it worse
Removing a neighbor's fence or structure yourself can create liability and escalate the dispute, so do not tear anything down without advice. Gather your deed, title policy, closing documents, prior surveys, photographs showing how long the structure has been there, and any correspondence with the neighbor. If a sale or refinancing is pending, tell your lawyer early, because a lender or title company may require the issue to be resolved or excepted from coverage. Talking with the neighbor can help, but avoid statements conceding the line until you know your position. Informal written agreements should be reviewed before signing, since some need to be recorded to bind future owners.
How encroachments get resolved
Many encroachments end with an agreement, such as an easement or license allowing the structure to stay, a boundary line agreement, or a sale of the strip of land. When agreement fails, a court action can establish the boundary and decide whether the encroachment must be removed or whether money damages are more appropriate, a choice courts weigh case by case. A title insurance claim may cover part of the cost if the policy includes that risk. We review the survey and documents with you, consider what you most need, whether clean title for a sale or simply peace with the neighbor, and talk through which path makes sense.
