What electronic signatures actually do

An electronic signature is a digital way to sign a document that creates a record of who signed it, when, and (in most cases) that the document has not been changed since the signature was added. It is not a picture of your handwritten signature — it is a piece of data attached to the file itself.

For most everyday documents — contracts, rental agreements, permission forms, loan papers — an electronic signature is legally binding in all 50 states and most countries. The law that makes this possible is called the E-SIGN Act, passed in 2000. The one major exception is documents that require a notary, like property deeds or powers of attorney. Those still need a person to witness your signature in person, though some states now allow remote notarization.

The signature itself can be as straightforward as typing your name, clicking a button, or drawing your initials on a touchscreen. What matters legally is not how fancy it looks, but whether both parties agreed to sign electronically and whether there is a record of when it happened.

Key Takeaways

  • Electronic signatures are legally binding for most documents in the United States, but not for documents that require a notary like property deeds.
  • You can sign documents through dedicated platforms like DocuSign or Adobe Sign, or through your document editor if it has built-in signing tools.
  • The simplest method is often a document editor's native signing feature, which keeps everything in one place and does not require a separate account.
  • When you sign electronically, the platform records the time, date, and your identity, creating a legal record that the document was signed and not altered afterward.

Signing through your document editor

If you are already using a document editor like Google Docs, Microsoft Word, or Apple Pages, you may be able to sign without leaving the platform. Google Docs has a built-in signature tool under the "Insert" menu — click "Signature," then either type your name, draw it with your trackpad or mouse, or upload an image of your handwritten signature. The signature appears as an image in the document itself, not as a legally binding electronic signature, so this method works for informal documents but not for contracts or agreements that need legal weight.

Microsoft Word and Apple Pages do not have native signing tools, so you would need to export the document and use a separate platform. Google Docs' signature feature is the most straightforward if you are already working in that editor, but understand that it is visual only — it does not create the kind of timestamped, tamper-evident record that legal documents require.

Using a dedicated signing platform

For documents that need legal standing — contracts, leases, loan agreements, employment forms — you need a platform that creates an actual electronic signature record. The most common are DocuSign, Adobe Sign, HelloSign, and Signaturit. These platforms attach metadata to the document that proves who signed it, when, and that no one has changed it since.

The basic process is the same across all of them: upload your document or paste the text, place signature fields where they need to go, add the email addresses of anyone who needs to sign, and send it out. The other signers receive an email with a link, open the document, type or draw their signature, and the platform records the timestamp. Once everyone has signed, you get a final PDF with a certificate of completion attached.

DocuSign and Adobe Sign are the largest and work with most document types, including PDFs, Word files, and images. HelloSign (owned by Dropbox) integrates with Dropbox if you store documents there. Signaturit is cheaper but smaller and less widely recognized by businesses. All of them offer free tiers that let you sign a few documents per month, though limits vary.

The difference between platforms and what to watch for

The main differences between signing platforms come down to price, integrations, and how much control you have over the signing experience. DocuSign and Adobe Sign both cost money after your free tier runs out — typically $10 to $40 per month depending on how many documents you sign. HelloSign is free for up to three documents per month, then $15 per month. Signaturit is free for up to five documents per month.

If you use Dropbox, Google Drive, or Slack regularly, check whether the platform integrates with those tools. Adobe Sign works with Microsoft 365 and Salesforce. DocuSign integrates with Slack, Salesforce, and many other business tools. HelloSign integrates with Dropbox natively. If you do not use any of those, the integrations do not matter — any platform will work fine as a standalone tool.

One thing to check before you sign up: whether the platform stores your documents on their servers or yours. DocuSign and Adobe Sign both keep copies of signed documents in their systems for record-keeping, which is standard practice and legally required for audit trails. If you want documents to stay only on your device or your own cloud storage, you have fewer options — most platforms need to keep a copy to prove the signature is legitimate.

How to send a document for someone else to sign

Start by uploading your document to the platform you chose. Most platforms let you drag and drop a file or paste text directly. Once the document is in the system, you place signature fields — small boxes that show where each person needs to sign. You can also add date fields, initial fields, or text boxes if you need the other person to fill in information.

Next, enter the email addresses of everyone who needs to sign. You can set the order — for example, you sign first, then the other person signs — or let everyone sign at the same time. Add a message if you want, then send. The other person gets an email with a link, clicks it, and signs on their screen. The platform records the time and date automatically.

Once everyone has signed, the platform generates a final PDF with a certificate of completion attached. This certificate proves who signed, when, and that the document has not been altered. read and save this file — it is your legal record of the signature.

Signing documents on your phone or tablet

All major signing platforms have mobile apps for iPhone, iPad, and Android. The experience is nearly identical to signing on a computer: you open the email link, navigate to the signature field, and sign by drawing on your screen with your finger. The timestamp and identity record are created the same way.

Drawing your signature on a phone screen is often easier than with a trackpad on a computer, since you can use your finger naturally. Most platforms let you redo the signature if you are not happy with it before you submit. Once you tap "Sign" or "Complete," the platform records the timestamp and sends the document to the next signer or marks it as fully signed.

What happens if you need to sign a document that requires a notary

Some documents — property deeds, powers of attorney, affidavits, and certain legal declarations — require a notary public to witness your signature. A notary is a person licensed by your state to verify your identity and watch you sign. Electronic signatures alone cannot replace this requirement in most states.

However, a growing number of states now allow remote notarization, where a notary watches you sign via video call instead of in person. Platforms like Notarize, NotaryNow, and LegitScript connect you with a licensed notary in your state who can verify your identity through video, watch you sign electronically, and add their notarial seal to the document. This costs more — typically $50 to $150 per document — but it means you do not have to find a notary's office and go in person. Check your state's notary laws to see whether remote notarization is allowed where you live.

Frequently Asked Questions

Is an electronic signature as legally binding as a handwritten one?

Yes, for almost all documents. The E-SIGN Act makes electronic signatures legally binding in all 50 states for contracts, agreements, and most business documents. The main exceptions are documents that require a notary, like property deeds or powers of attorney, which still need a person to witness your signature in person in most states.

Can someone forge my electronic signature?

It is much harder than forging a handwritten signature. Electronic signatures create a timestamped record tied to your email address and the platform's servers. If someone tried to add a fake signature, the timestamp and identity record would not match reality, and the document would fail verification. Handwritten signatures are easier to copy.

Do I need to pay to sign documents electronically?

Not always. Google Docs has a free signature tool, though it only creates a visual signature, not a legally binding one. DocuSign, Adobe Sign, HelloSign, and Signaturit all offer free tiers that let you sign a limited number of documents per month. If you sign more than a few documents per month, you will likely need to pay for a subscription.

What if I sign a document and then change my mind?

Once you sign and submit, the document is legally binding and the signature cannot be undone. You would need to contact the other party and ask them to void the agreement or sign a new version. The electronic signature record proves you signed, so you cannot claim you did not. Always read the document carefully before you sign.

Can I use an electronic signature on a PDF I downloaded from a website?

Yes, but it depends on the PDF. Most PDFs can be uploaded to a signing platform and signed. Some PDFs are locked or read-only, which means you cannot add signatures to them directly. In that case, you would need to read the PDF, print it, sign it by hand, and scan it back in — or ask the person who sent it to you for an editable version.
