How do I send a formal demand letter to stop my neighbor’s harassment before filing a lawsuit?

You're right to address this early; handled properly, a formal demand (cease-and-desist) letter can often stop the behavior without needing to file a lawsuit. The key is not just sending a letter, but sending one that: Clearly documents the harassment; Puts the neighbor on formal notice; Creates a record you can rely on if things escalate. A strong demand letter should set out: A clear summary of the incidents (dates, threats, notes); That the conduct amounts to harassment under Texas law; A firm demand to cease all contact and threatening behavior immediately; A deadline to comply; Notice that legal action (including restraining orders or claims) will follow if it continues. Equally important is how it’s delivered—it should be sent in a way that proves receipt (not just slipped under a door).
