Turning a pattern into evidence
Strong documentation is what turns "my landlord is harassing me" into evidence a court, agency, or attorney can act on. Because harassment is often a pattern, a consistent record is powerful.
Keep a detailed log. For each incident, write down the date, time, what happened, exactly what was said or done, where it occurred, and any witnesses. Note how it affected you. A running timeline shows the pattern that single incidents cannot.
Save every piece of communication — texts, emails, voicemails, notices, and letters — and do not delete them. Where it is legal and safe, keep written records of interactions; putting communication in writing also creates its own evidence. Photograph anything physical, like a changed lock or a shut-off utility.
If police, code enforcement, or others got involved, keep report numbers and copies. Statements from neighbors who witnessed conduct can help too.
Organize everything by date so the pattern and any connection to your complaints is clear. This record protects you whether you are pursuing penalties or defending your tenancy. If you want help understanding what your documentation shows, a free, confidential review can walk you through it.
