What is an s-signature?

An s‑signature, also written as /s/ signature, is a simple way to sign an electronic document by typing your name between forward slashes. It’s a typed signature that still counts as a legally recognized electronic signature in many contexts. An s‑signature can look like:

/Jimmy Doe/
or
/s/ Jimmy Doe

It’s a fast, keyboard‑friendly way to sign when you can’t sign by hand, don’t have a touchscreen, or need to meet specific filing requirements, especially in legal, business, and patent workflows.

What does /s/ mean?

The /s/ notation is a standardized way to show that a typed name is being used as a signature. It signals that the signer is intentionally signing electronically rather than providing a handwritten mark. In conformed signatures, the signer places an “s” between two forward slashes before their typed name, such as:

/s/ John Smith

This style is widely used in legal filings, government submissions, and patent applications.

Why do lawyers use /s/ before a name?

Lawyers, courts, and government agencies use /s/ signatures because they:

• allow fast signing without printing
• work across devices and filing systems
• meet many electronic filing requirements
• provide a consistent, recognizable signature format
• reduce delays caused by wet signatures

In many legal workflows, an s‑signature is accepted as long as it follows the required format and is placed intentionally by the signer.

Why use s-signatures?

Flexibility

Electronic signatures are necessary to keep business moving, especially when you can’t meet face to face. You never want technical issues to get in the way of collecting signatures. An s signature makes it simple to collect, regardless of a person’s device or tech savviness.

Convenience

Depending on where and how you are doing business, the option of an s-signature may help you conduct business more quickly by speeding up the signing process. For example, when you’re e-filing a patent application, you can quickly use a form-fill app to add a digital signature from any keyboard. This is just one of many possible examples of when an s-signature might work better than a wet signature.

Compatibility

S‑signatures work in many government and business systems that accept typed signatures but don’t support drawn or uploaded signatures.

How to use an /s/ signature format: /s/ signature format

Using an s‑signature is one of the simplest ways to sign electronically when you can’t draw or upload a handwritten signature. If you need to learn how to type an s‑signature, or how to sign electronically with /s/, here are a few rules to follow:

  • Use letters, Arabic numerals, or both
  • Use correct spacing between words
  • Include punctuation if needed (commas, periods, hyphens)
  • Place the signature between forward slashes
  • Add the signature yourself: no one else can add it for you

Examples:

  • /Jane Doe/
  • /s/ Jane Doe
  • /J. A. Doe/

This makes it easy to add a legally recognized typed signature to forms, contracts, and filings, especially when you need a quick, keyboard‑friendly alternative to a handwritten signature. The guidelines above explain exactly how to format an s‑signature correctly and how to use it in documents, including how to insert /s/ in a PDF.

Regulations

The rules around e-signature validity vary from country to country and region to region.

For example, there are many laws that cover the validity of e-signatures in the United States. The Uniform Electronic Transactions Act (UETA) in 1999 and the US Electronic Signatures in Global and National Commerce (ESIGN) Act in 2000 both set regulatory guidelines on electronic signatures, but every state has not adopted these.

The United States Patent and Trademark Office (USPTO) and many other government agencies accept s-signatures for electronic filing. The Manual of Patent Examining Procedures (MPEP) 501 and 502 also covers regulations on s-signatures for patents.

As always, consult your attorney for advice on using an s-signature relevant to your use case.
