Fax Cover Sheet: The Template That Stands Up as Evidence
What must a fax cover sheet contain to serve as evidence, protect professional confidentiality and safeguard your deadlines? Complete template and pitfalls to avoid.

Short answer: a fax cover sheet is nowhere required by French law — and that is precisely why it matters so much. In a dispute, a judge has only two things to work with: the transmission report from the machine or the service, and the actual content of the pages received. The cover sheet is the only place where you state, in black and white, who is sending, to whom, what, how many pages, and under what confidentiality reservation. Four items make all the difference: full identification of the sender (company name, sending fax number, contact person, callback telephone number), a subject line tied to a file reference, the page count including the cover sheet, and a confidentiality clause requesting destruction in the event of misdirected receipt. The most common mistake is not forgetting the cover sheet: it is writing "3 pages" when the transmission actually contains 4, which hands the opposing party a ready-made argument about the integrity of the transmission.
Why a judge looks at the cover sheet
Fax occupies a peculiar place in the law of evidence. It does not benefit from the presumption of reliability attached to qualified electronic registered delivery, governed by the European eIDAS Regulation and the decree of 9 May 2018. It is assessed as a writing in electronic form within the meaning of Articles 1366 and 1367 of the French Civil Code, and above all as an item subject to the trial judge's sovereign appraisal. We develop this point in our article on the evidentiary value of a fax before a judge.
What this means in practice: the probative force of a fax is built up through a body of corroborating evidence. The transmission report establishes that a call went through to a given number at a given time, with a given number of pages transmitted. It says nothing about the content. The cover sheet, on the other hand, documents the content and ties it to a file, a named recipient, a date. The two pieces either corroborate each other — or contradict each other.
An example seen time and again in tenancy or employment tribunal litigation: the report states "5 pages transmitted", the cover sheet announces "3 pages (excluding cover sheet)", and the recipient claims to have received only two sheets. Nobody can reconstruct the transmission any more. A consistent page count would have settled the matter in a single line.

The items that must appear on it
1. Full identification of the sender
The sending number prints automatically in the header on properly configured fax machines (the familiar TSI, Transmitting Subscriber Identification), and online services reproduce that line. But a bare number is not enough: your recipient needs to know who to reply to.
What to include:
- company name or full name, postal address;
- the sender's capacity (HR department, law firm, managing agent, manager, etc.);
- first and last name of the individual sending;
- a voice callback telephone number — not just the fax line;
- contact e-mail address;
- where applicable, company registration number, bar roll number, or locker (toque) number.
For regulated professions, that "capacity" line is not cosmetic: it ties the transmission to professional confidentiality obligations and justifies the confidentiality clause that follows.
2. A named recipient, not an anonymous department
"For the attention of the litigation department" is worth far less than "For the attention of Ms Martin, litigation department, file ref. 2026/4418". In large organisations, a fax arriving on a shared number is routed by hand; a name speeds up routing and, in the event of a dispute, proves that you addressed the document to the right person.
3. The subject and file reference
One precise line, reusable in a follow-up e-mail: "Formal tax appeal — 2025 tax assessment notice — ref. 2026/4418". This is the heading you will find again three years later in your archive, and the one your legal adviser will cite.
4. The page count, with an explicit convention
The wording that leaves no room for argument:
Total number of pages transmitted: 4 (cover sheet included)
Both conventions exist ("cover sheet included" / "excluding cover sheet"), and neither is wrong — but you must name one of them. And above all, the figure must match the transmission report. If your online service tells you 4 pages were transmitted, your cover sheet must say 4.
5. The confidentiality clause
This is the most copy-pasted and least understood item of all. It creates no new obligation for a third party: its value is in proving your diligence. Where a fax has gone to the wrong number, the CNIL assesses the measures taken to limit the consequences of a data breach. An explicit clause, backed by a callback procedure, carries weight in that assessment. We set out what to do in our article on a fax sent to the wrong number.
Standard wording:
This document and its attachments are confidential and intended solely for the person named above. If you have received this message in error, please notify us immediately on the number indicated, destroy all pages without keeping any copy, and refrain from disclosing them to any third party. Any unauthorised distribution, reproduction or use is prohibited.
6. The date, the time and the signature
A date written by hand or typed on the cover sheet does not have the value of a qualified timestamp, but it must match the date on the transmission report. A discrepancy of several days between the date shown on the document and the date of transmission invariably draws comment from the other side. Where the substantive document is signed, a signature on the cover sheet is unnecessary; where the cover sheet serves as a schedule of enclosures — a frequent scenario when filing documents — it should be signed.
A reusable cover sheet template
| Block | Content |
|---|---|
| Header | Company name, address, registration / bar roll number, logo |
| From | First and last name, role, voice tel., e-mail, sending fax no. |
| To | First and last name, department, organisation, recipient's fax no. |
| Date / time | DD/MM/YYYY — HH:MM |
| Subject | Explicit heading + file reference |
| Pages | "Total: N (cover sheet included)" |
| Schedule of enclosures | Numbered list of documents: 1. … 2. … 3. … |
| Deadline statement | "Sent within the X-day period expiring on DD/MM/YYYY" |
| Confidentiality | Full clause |
| Acknowledgement | "Please confirm receipt by return fax or by e-mail to …" |
The schedule of enclosures is the part almost nobody fills in — and the one that saves bulky files. A numbered five-line list makes it immediately obvious that document no. 3 is missing, whereas a bundle of eighteen pages with no index simply cannot be checked.
The deadline statement is the other reflex to adopt whenever the transmission forms part of a time-barred procedure: reservations notified to a carrier, an insurance claim, a challenge to a formal warning. Stating that you are acting within the deadline, and which deadline, crystallises your position as at the date of sending.
For firms producing these pages in bulk, a customisable rubber stamp carrying the fixed details (company name, numbers, abridged clause) saves real time on paper transmissions, and avoids handwritten cover sheets that become illegible once the fax has been compressed to 200 dpi.
What degrades legibility after transmission
A fax is not a PDF: the T.4/T.30 protocol transmits a binary image, most often at 204 × 196 dots per inch in fine mode. Anything grey, thin or coloured either disappears or turns into a smudge.
Practical rules:
- Point size 11 to 12 minimum, with a crisp sans-serif typeface (Arial, Helvetica, Verdana). High-contrast faces such as Times lose their thin strokes.
- No grey backgrounds, no white text on black, no screened boxes. Solid black on white, nothing else.
- Simplified logo: a gradient logo turns into a blob. Many firms keep a monochrome "fax" version of their letterhead.
- Margins of at least 15 mm: the paper-feed mechanisms crop the edges, and the TSI line prints at the top of the page, sometimes right over your header.
- Handwritten annotations in black broad-tip pen, never in pencil or yellow highlighter (invisible after scanning).
For mixed transmissions — paper originals plus digital documents — a document scanner with an automatic feeder set to black and white at 200 dpi produces exactly the rendering the fax protocol will transmit: you see on screen what the recipient will receive, before you send. It is the best quality control there is, and it costs one minute.

Cover sheets and online fax: what changes
With a web-based service, the old typed cover sheet fed through the paper tray gives way to an automatically generated first page or a PDF you prepare yourself. Two approaches:
The cover sheet generated by the service. Convenient, but often threadbare: sender's name, numbers, page count, sometimes a "message" field. Always check that it is actually counted in the total reported, and that it carries your real sending number rather than a shared technical number — something to verify when choosing a provider, along with the other criteria we list in our comparison of the criteria for choosing an online fax provider.
Your own PDF template. It takes longer to set up, but it is the only way to have a schedule of enclosures, a deadline statement and a confidentiality clause that match your own practice. Build a template in your word processor, export it to PDF/A for archiving, and keep it alongside your acknowledgements. The whole set — cover sheet + enclosures + transmission report — forms the evidential file you will later produce. On retention periods, see our guide on how long to keep your fax confirmations.
One ergonomic detail that counts when you send ten faxes a day: keep a printed blank template in a flap document folder next to the workstation, for urgent transmissions filled in by hand. And for the physical archiving of sensitive transmissions, expanding archive wallets in permanent paper prevent the yellowing of thermal paper, still used by some older receiving machines.
Special cases by profession
Healthcare. Medical confidentiality (Article L. 1110-4 of the French Public Health Code) means nothing medical should appear on the cover sheet. No diagnosis in the subject line, no name of any condition, and ideally no patient name in the clear if the fax arrives on a shared machine — a file reference is enough. See our recommendations on medical faxing and health data.
Lawyers and enforcement officers. The cover sheet states the bar locker or the practice, and the clause restates professional confidentiality. For procedural documents, fax does not replace the methods of communication laid down by the Code of Civil Procedure: it accompanies, it does not constitute.
HR. Never state a disciplinary reason in the subject line: a fax arrives on a shared machine. "Correspondence relating to the employment contract — employee ref. 1182" is enough.
Real estate. State the reference of the lot and of the mandate, and for notices to quit or formal demands, make the deadline statement systematic.
Frequently asked questions
Is a cover sheet mandatory?
No. No French legislation requires one for an ordinary fax. Some government departments and court registries do, however, require a precise accompanying schedule when documents are filed: in that case it is the organisation's own rules that apply, not a general rule.
Should the cover sheet be counted in the total?
Both conventions are accepted. What is wrong is failing to specify which one you are using. Write "N pages, cover sheet included" and check that N matches the figure on the transmission report exactly.
Does the confidentiality clause have any legal value?
It imposes no contractual obligation on a non-consenting recipient. Its effect is evidential and practical: it shows that you took a protective measure, which the CNIL takes into account when assessing a data breach, and it does in practice encourage a mistaken recipient to destroy the pages.
Can you put a QR code or a link on the cover sheet?
Technically yes, but a QR code transmitted at 200 dpi with binary compression is often unreadable. Prefer a short alphanumeric reference, in large characters, that the recipient can copy out.
What if the recipient says they only received the cover sheet?
Call back immediately by telephone, keep the transmission report showing the number of pages, and resend everything with "second complete transmission" in the subject line. A silent resend muddles the chronology of the file.
Do you need a cover sheet for a fax that is received and then forwarded?
Yes, and a separate one. Add your own cover sheet in front of the forwarded document, stating its origin: "Document received on DD/MM from [organisation], forwarded for information". Without this, the original TSI at the top of the page creates confusion as to who the actual sender is.
In summary
- The cover sheet is not mandatory, but it is the only document where you control identification, subject and page count — three things the transmission report does not provide.
- Six essential blocks: full sender details including a voice telephone number, a named recipient, subject + reference, page count with an explicit convention, schedule of enclosures, confidentiality clause.
- The page figure must match the transmission report. This is the discrepancy most exploited in litigation.
- Add a deadline statement every time the transmission forms part of a time-barred procedure.
- Legibility: black on white, point size 11 minimum, no grey or screening, 15 mm margins, monochrome logo.
- Regulated professions: nothing medical, disciplinary or sensitively personal in the subject line — a file reference is enough.
- Archive the cover sheet together with the enclosures and the report: it is the set as a whole that forms a body of evidence, not an isolated item.
