Ofc. Ramirez filed the incident report.
In formal legal documents, officer is often written out on first reference.

Off. vs Ofc. vs Officer (What’s Actually Correct)
All three forms can be correct, but they are not interchangeable.
When Off. Looks Outdated
Off. is still acceptable, but it can feel old-fashioned in modern professional writing. Many style guides now recommend spelling out officer unless space is limited.
Why Ofc. Is Not Interchangeable
Ofc. is strongly associated with police officer usage. Using Ofc. for a corporate or military role can look incorrect or confusing.
Wrong example
Ofc. Smith, Chief Financial Officer
Correct example
Smith, CFO
When Spelling It Out Is Mandatory
You should always write officer in full in legal documents, academic writing, contracts, and first mentions in formal reports. Clarity always comes before brevity.
Capitalization, Periods, and Style Guide Rules
Correct formatting matters as much as the abbreviation itself.
AP Style vs Chicago vs Legal Writing
AP Style prefers fewer abbreviations and often recommends spelling out officer unless space is limited.
Chicago Style allows abbreviations but emphasizes consistency.
Legal writing usually avoids abbreviations unless they are well established.
When Periods Are Dropped
Periods are common in Off. and Ofc., but many modern styles drop them in titles like CFO or CEO. Mixing styles within the same document should be avoided.
Sentence vs Heading Usage
In headings, abbreviations are often capitalized and simplified. In body text, clarity and consistency matter more than brevity.
