Do you have a PDF or electronic form that needs your signature, but you can’t seem to add one? 

Electronic forms and fillable PDFs are becoming more common. But sometimes we still receive a form that we need to add a signature to, but we can’t seem to add one. This can be very frustrating. 

There could be a number of reasons for this. But fortunately, we’ve compiled the best fool-proof methods for adding a wet signature to a PDF, document, form, or anything else you may need to add it to. 

What is a Wet Signature? 

A wet signature (also called a “wet ink signature”) is a signature that is written by hand, on paper. It could be written with a pen, pencil, marker — anything, as long as it’s handwritten on paper. 

3 Different Types Of PDF Signatures

  1. Wet 
  2. Electronic
  3. Digital 

1. Wet Signatures 

Like mentioned above, wet signatures are simply signatures that are written by hand, on paper. With the rise of electronic forms and PDFs, wet signatures are slowly becoming extinct. 

Why? 

A few reasons: 

  • Time: Wet signatures take longer to receive, because you have to make sure the right parties receive the document, they have to sign it, then they have to send the document back to you. It’s getting more common to simply email forms with prompts for their electronic signatures. 
  • Cost: Wet signatures require ink, paper, printers/scanners, and time, just to name a few requirements. These costs add up and multiply depending on the size of the company and number of employees. 
  • Storage: After receiving a physically signed document, the next step is often to organize it in a filing cabinet, or scan a copy, then file it. Storage takes up space in the office, requires furniture like cabinets to store things, and requires time to sort through the files (and go through the files every time you need to find something). 

2. Electronic Signatures

Electronic signatures are simply wet signatures that are done electronically. You could use a mouse or stylus to create a written signature on an electronic document, or you could save a wet signature that you could apply repeatedly to documents, as needed. 

Examples of electronic signatures:

  • Email signatures at the end of emails. 
  • An image (or stamp) of a handwritten signature.
  • A name or initials typed onto an electronic form or document. 
  • Clicking “I agree” to online contracts or policies. 
  • A signature that’s handwritten with a mouse or touchscreen device (credit card machine, tablet, smartphone, etc.)

3. Digital Signatures 

Digital signatures encrypt documents with digital codes that are difficult to duplicate, adding to the validity, authenticity, and security of the document. 

They help guarantee to  the recipient of the document that the document was signed by the right person, and that the contents of the document haven’t been altered by a third party. 

An example of digital signature would be a Windows certificate that validates the author and owner of the signature. 

Digital signatures are often used for official documents, such as electronic tax forms, business permits, online applications, and more.

Adding watermarks is another common way to show authenticity of a document. 

When to Use a Wet Signature

Sometimes you’ll need to sign something with a wet signature. Maybe for security or to prove authenticity. Wet signatures are often legally required, depending on the document. 

For example, the following all require wet signatures: 

  • Physical document on hand.
  • A different party requires a signed copy of it. 
  • Bank loans, leases, mortgages, anything involving money.
  • Business contracts.
  • Legal documents. 
  • Medical forms. 
  • Notary public. 
  • Wills. 
  • Trusts. 
  • Adoptions. 
  • Divorce proceedings. 
  • Court orders. 
  • Evictions. 
  • Insurance benefits.
