What Does /s/ Signature Mean?

If you have seen "/s/ John Smith" at the bottom of a legal document and wondered what it means, you are not alone. The /s/ notation is one of the oldest forms of electronic signature and is still widely used — especially in legal and government documents.

What Is a /s/ Signature?

The /s/ signature (pronounced "slash-S") is a conformed signature — a typed representation of a person's name preceded by "/s/" to indicate the document has been electronically signed.

Example:

By: /s/ Jane Doe
Name: Jane Doe
Title: Chief Executive Officer
Date: February 16, 2026

The "/s/" tells the reader that a signature was applied, but because this is an electronic or printed copy, the handwritten signature has been replaced with a typed name.

History and Origin

The /s/ convention originated from federal court electronic filing systems in the 1990s. When courts moved from paper to electronic filings:

Paper filings had handwritten signatures
Electronic filings needed a plain-text signature representation
The /s/ convention became the standard

The Federal Rules of Civil Procedure (Rule 5(d)(3)(C)) and local court rules formalized the practice.

Where Is /s/ Signature Used Today?

Federal Courts (PACER/ECF)

Electronically filed court documents commonly use /s/ signatures. Attorneys register for an ECF account; login credentials help authenticate their /s/ signature.

SEC Filings

The Securities and Exchange Commission accepts /s/ signatures on filings such as 10-K, 10-Q, 8-K reports, proxy statements, registration statements, and officer/director certifications.

Patent Applications

The USPTO accepts /s/ signatures on patent applications, Office action responses, and declarations.

Government Forms and Legal Correspondence

Many agencies accept /s/ signatures on electronic forms, and attorneys routinely use them in emails, letters, and electronic memoranda.

/s/ Signature vs. Modern E-Signatures

Feature	/s/ Signature	Modern E-Signature
Authentication	No built-in verification	Email/identity verification
Audit trail	None built-in	Timestamps, IP, device
Tamper detection	None	Document hash integrity
Visual signature	Text only	Drawn, typed, or uploaded
Identity proof	Anyone can type /s/	Unique signing links
Court acceptance	In authorized filings	Broadly accepted

When Should You Use /s/ vs. a Full E-Signature?

Use /s/ when:

Filing documents in courts that require it
Submitting SEC or government filings
Following specific regulatory formatting rules

Use a full e-signature platform when:

Signing business contracts
You need an audit trail for legal protection
Identity verification is important
You want tamper detection and dispute-ready proof

Frequently Asked Questions

What does /s/ mean on a document?

The /s/ notation (forward slash, letter "s", forward slash) followed by a person's typed name indicates a conformed or electronic signature. For example, /s/ John Smith means "signed by John Smith." It is commonly used in court documents, government filings, and legal correspondence.

Is a /s/ signature legally binding?

Yes, in the appropriate context. In court filings under rules that permit electronic filing (such as Federal Rules of Civil Procedure Rule 5(d)(3)), a /s/ signature can be legally binding. In general business contracts it may also qualify as a simple electronic signature under ESIGN, though dedicated platforms provide better authentication and audit trails.

Where is /s/ signature commonly used?

It is most common in federal and state court electronic filings (PACER/ECF), SEC filings, patent applications, government forms, corporate board resolutions, and attorney correspondence.

Is /s/ the same as an electronic signature?

A /s/ notation is one form of simple electronic signature (SES). It provides minimal authentication — there is no built-in proof that the named person typed it. Modern platforms like WPsigner add identity verification, audit trails, and tamper detection.

Should I use /s/ for business contracts?

Usually no. /s/ is best for court or agency filings that expect that format. For business contracts, use a platform that captures intent, identity evidence, and an audit trail.

Can WPsigner replace /s/ signatures?

For business documents, yes — WPsigner provides stronger evidence than a typed /s/ line. For court or SEC filings that specifically require /s/ formatting, follow those filing rules separately.
