Documenting tenant violations is one of the most overlooked aspects of landlord management, yet it is often the deciding factor in eviction trials. Judges need to see a clear timeline of events, not broad or emotional accusations. The better organized your evidence, the more persuasive your case becomes.

The Importance of a Violation Log

A violation log is a chronological record of every issue involving the tenant. This is not just helpful, it is essential. Logs show patterns of behavior, repeated warnings, and how long the issue has persisted. Judges appreciate organized notes because they paint a picture of ongoing problems. When logs contain dates, times, names, and descriptions, the court sees them as credible and objective.

Using Photos and Videos to Strengthen Your Case

Visual evidence is powerful. Photos and videos showing damage, nuisance behavior, or unauthorized occupants help the judge understand the severity of the problem. When possible, include a timestamp or reference point that verifies when the image was taken. Always obtain visual evidence lawfully—never enter a tenant’s unit without legal permission or notice unless it’s an emergency.

Saving Communications and Written Warnings

Text messages, emails, and letters are excellent evidence of communication between landlord and tenant. Courts want to see whether the tenant was given opportunities to correct their behavior and whether the landlord acted reasonably. A landlord who sends polite, consistent messages is viewed far more favorably than one who relies on verbal warnings with no record.

Preparing Evidence Before Filing

By the time you file an Unlawful Detainer, you should already have your evidence organized into categories: lease agreements, notices, rent ledgers, violation logs, photos, written warnings, and proof of service documents. Organizing this before filing makes court preparation easier and helps avoid mistakes that cause delays.
