How to Write a Daily Occurrence Book (DOB) Entry That Holds Up in Court

8 min read· Updated 2026-07-07· Free · No signup

Structure and language for DOB entries that survive disclosure and cross-examination. This guide gives a straight, evidence-based answer with the practical steps, mistakes and FAQs UK security professionals need in 2026.

Key takeaways

  • One entry per event, chronological, no gaps.
  • Facts only — observed, heard, said. No opinion.
  • Include time, location, people, actions, outcome, sign-off.
  • Never overwrite; a mistake gets a single strike-through and initials.

Why the DOB matters

The Daily Occurrence Book is admissible evidence. Courts read it, insurers read it, HR reads it. Sloppy entries have lost more cases than sloppy incidents.

The five-line template

Time / Location / Who / What (observed) / Action (taken) / Outcome / Officer sign-off. Five lines minimum. Add continuation entries as events unfold.

Language discipline

'Male, ~30, black jacket, walked from bar to smoking area, poured drink over female's head' — not 'aggressive drunk started causing trouble again'.

Common errors that destroy credibility

Gaps, retrospective entries, opinions, judgemental language, illegible handwriting, missing signatures. All fatal in cross-examination.

Digital DOB systems

Digital DOB systems (SmartTask, Trackforce, Timegate) auto-timestamp and audit-log, removing most integrity risks. Written DOBs still exist in many sites and follow the same rules.

Quick checklist

  • Entry made within 30 minutes of event
  • Facts only, no opinion
  • Signed with role and time
  • Continuation entry logged if events developed

Common mistakes

  • Retrospective 'catch-up' entries at the end of shift.
  • Editorialising in the narrative.

Frequently asked questions

Can I use shorthand?+

No. Every entry must be readable by someone unfamiliar with the site.

Can I amend an entry the next day?+

You add a continuation entry. You never amend the original.

Is this guide free?+

Yes. Every Guard.Academy guide is free, no signup required. Bookmark it and share it with your team.

Does this replace an SIA-approved course?+

No. Guard.Academy is a CPD and study resource. A licensable role in the UK still requires the SIA-approved qualification from an accredited provider.

How current is the information on how to write a daily occurrence book (dob) entry that holds up in court?+

We refresh guides on a rolling schedule and note the last-updated date at the top. If the SIA or Home Office issue material changes we prioritise those updates first.
