Suburban Boundary Dispute Help

I need a property-law professional to guide me through a boundary dispute in a suburban neighborhood. The issue centers on an alleged encroachment onto my lot line, and I already have evidence that documents the problem.

Here’s what I want from you:
• Review the materials I supply that show the encroachment and any supporting deeds or surveys I can obtain.
• Explain my legal position in clear, practical terms, including the options I have before escalating.
• Draft a concise, well-structured letter I can send to the adjoining owner (or their counsel) that asserts my rights and proposes a resolution.
• Outline the next steps I should be prepared for—such as commissioning a formal survey, filing a complaint, or seeking mediation—so I understand timelines, costs, and likely outcomes.

Please be comfortable with boundary disputes and local property law, and be ready to work collaboratively via video or email to clarify facts and refine the letter. A prompt turnaround and straightforward advice are important to me.
