How to Document Harassment: Evidence That Holds Up

Harassment often becomes harder to explain when it has happened repeatedly, across different places or through several channels. Knowing how to document harassment gives you a clear, factual record that can support a report to Police, an employer, a school, a lawyer, or another appropriate authority. It can also help you make better decisions about your immediate safety.

The objective is not to create the largest possible file. It is to preserve reliable information: what happened, when and where it happened, who was involved, what evidence exists, and how the conduct affected you. A well-kept record is easier for others to assess, verify and act on.

If you believe you are in immediate danger, contact emergency services on 111. Do not delay urgent safety action in order to collect evidence.

How to document harassment from the first incident

Start a contemporaneous incident log. This is a running record made as soon as practical after each event, while details are still fresh. Use one secure notebook, document or app rather than scattered notes, and keep entries in date order.

For each incident, record the date, approximate time, location, names or descriptions of people involved, and a concise account of what occurred. If exact words were used, place them in quotation marks and write them as accurately as you can. Separate what you personally saw or heard from what someone else later told you.

Include practical details that may establish a pattern. For example, note whether the person contacted you after being asked to stop, appeared at a location they would not normally know you were attending, used different mobile numbers or social media accounts, or involved friends, colleagues or family members. Record the impact as well: missed work, changed routines, fear for safety, damaged property, or unwanted contact with children or clients.

Avoid adding conclusions such as “they were trying to ruin my life” unless this is clearly identified as your belief. Facts carry more weight than assumptions. A useful entry might read: “7.40 am, outside the office on Queen Street. I saw a dark blue sedan stop across the road. The driver appeared to be [name]. The vehicle remained there for approximately 15 minutes. At 7.55 am, I received a text from [number] stating, ‘I know where you work.’”

Record the whole pattern, not only the worst event

One message or encounter may appear minor when viewed in isolation. Repeated unwanted contact, monitoring, threats, intimidation or interference can look very different when the full sequence is documented. Keep recording incidents even after you have made an initial complaint.

Be accurate about gaps. If nothing happened for several weeks, do not try to fill the space with recollection. A clean timeline with clear dates is more credible than a record that overstates events.

Preserve original digital evidence

Messages, call logs, emails, voicemails, social media posts and photographs can disappear quickly. Save the original material before blocking an account, deleting an app or changing a mobile number. Screenshots are useful, but they should not be the only copy.

Take screenshots that show the sender’s account or number, the date and time, and the full context of the exchange where possible. Capture profile pages, usernames, URLs shown in the browser, comments and any identifying details. If there are numerous messages, preserve the relevant thread in order rather than selecting only the most offensive lines.

Keep the original emails and voicemails. Save copies to a secure location, such as an encrypted storage device or a protected cloud account to which the other person has no access. Give files meaningful names, for example: “2026-09-14_2135_text-message_from-021xxxxxxx”. Do not edit images, crop out important context or alter audio files.

If abusive content is posted publicly, capture it promptly. A post may be deleted, an account renamed, or a platform may remove material after a complaint. Note when you accessed the content and who else may have seen it.

Where possible, retain the device on which key evidence was received. A forensic review may depend on original data, device settings or account information that screenshots alone cannot show.

Protect physical evidence and scene details

Harassment is not always digital. Unwanted letters, gifts, notes, damage to property, items left at a home or workplace, and repeated attendance at a location should all be documented carefully.

Photograph items where they were found before moving them, if it is safe to do so. Take wider photographs to show the setting, followed by close images of labels, damage, handwriting or other relevant details. Record the time you discovered the item, who had access to the area, and whether CCTV may be available.

Do not handle an item unnecessarily or attempt to investigate it yourself. Place it somewhere safe if required, but preserve it in the condition in which it was found. If there is a threat, suspected tampering, or any reason to think the item may be unsafe, contact Police and follow their instructions.

CCTV can be particularly time-sensitive. Make a note of cameras at neighbouring properties, shops, car parks, apartment buildings or workplaces, along with the likely time window. Footage may be overwritten within days. Ask the owner or manager to preserve relevant footage, but do not assume it will be released directly to you.

Identify witnesses and supporting records

Witnesses do not need to have seen every incident to be helpful. A colleague may have overheard a call, a neighbour may have observed a vehicle repeatedly outside your address, or a friend may have received concerning messages from the person involved.

Record each witness’s name, contact details, what they directly observed, and when you spoke with them. Do not coach them or ask them to speculate. Their independent recollection is more useful than a statement shaped around your account.

Supporting records can also establish timing and impact. Depending on the circumstances, these may include workplace security logs, diary entries, medical appointments, call records, vehicle registration details, building access records, delivery records, bank transactions or reports made to a platform. Keep these materials in their original form wherever possible.

Keep the evidence secure and controlled

Harassment can escalate when the person involved gains access to your devices, passwords or location. Review account security, change passwords from a safe device, activate multi-factor authentication, and check whether location sharing is active on apps, vehicles or family accounts.

Keep a separate copy of your incident log and evidence where it cannot be easily accessed or destroyed. If you share a household, device or account with the person involved, avoid storing the only copy there. Tell one trusted person where the record is held and how to access it if necessary.

Be cautious about posting evidence publicly. Public discussion can expose private information, alert the other person to your evidence, complicate a workplace process, or create further risk. Preserve first, then seek advice on the appropriate reporting path.

Reporting harassment in the right setting

The best reporting route depends on the conduct, your relationship to the person involved, and the immediate risk. Threats, stalking, violence, property damage, repeated unwanted contact or conduct that causes fear for safety may warrant a Police report. Workplace harassment should usually be reported through the employer’s formal process, with copies of relevant evidence retained outside the work system where appropriate.

For harassment connected to a school, tertiary provider, club, landlord, online platform or professional setting, follow the available complaint process and request written confirmation that your report has been received. Provide a focused evidence pack rather than forwarding hundreds of unsorted files.

A practical report includes a short chronological summary, your incident log, key screenshots or files, names of witnesses, and a clear statement of what assistance you are seeking. That may be an investigation, preservation of CCTV, a safety plan, a no-contact direction, a workplace intervention, or advice about further options.

Do not exaggerate to make a report sound more serious. State what you know, identify what you do not know, and explain why you are concerned. Clear reporting helps decision-makers assess risk quickly.

Know the limits of self-gathered evidence

It is understandable to want certainty, especially when you suspect someone is following you, accessing your accounts or using another person to make contact. However, confronting the person, following them, entering private property, accessing accounts without permission, or installing tracking or recording equipment can increase risk and create legal problems.

Recording conversations, monitoring communications and surveillance can involve privacy, employment and legal considerations. The appropriate approach depends on the facts. Before taking steps that may intrude on another person’s privacy, obtain qualified legal advice or speak with an appropriately licensed professional.

For complex or escalating matters, an independent investigation may assist by establishing facts, locating and preserving relevant information lawfully, and producing detailed reporting for legal, employment or security purposes. The Neill Group works discreetly with private, commercial and government clients where professional field capability and clear evidence handling are required.

A calm, well-organised record gives you more than paperwork. It creates a reliable account at a time when harassment can make events feel confusing, isolating and difficult to explain. Begin with the next incident, preserve what is already available, and prioritise your safety at every step.
