My neighbor built a new fence while I was at work, and looking at the survey stakes, it is clearly two feet onto my property. They cemented the posts already. What would you do?

Gather all documentation, including photographs, surveys, correspondence, and any legal advice you’ve received. Presenting a well-documented case will be crucial in court to demonstrate the encroachment and your efforts to resolve the issue.
11. Protect Yourself From Future Boundary Disputes
Once the issue is resolved, take steps to prevent future disputes. Clearly mark your property boundaries with stakes or a fence if permissible.
Maintain good communication with your neighbor and keep records of any agreements or surveys. Regularly review your property boundaries to ensure no future encroachments occur. Taking these steps can help maintain a peaceful coexistence with your neighbors and protect your property rights.
