Signing a Document

This is not legal advice, and what makes a signature valid differs by jurisdiction and by document type.

Three things called signing

Signing something yourself. Somebody sent you a document; you need it back with your signature on it.

Collecting a signature from somebody else. You send, they sign, you receive it back — which is a workflow rather than an act.

And signing in a way that can be relied upon later, where a dispute is plausible and the process itself has to be demonstrable.

The three have different answers, and most purchases happen because the first was conflated with the third.

Signing something yourself

Built into both major operating systems.

Open the PDF, add a signature, save, send back. No account, no subscription, no upload of a document to anybody's server.

Where it stops: nothing records that you signed it, when, or that the document was unaltered afterwards. For an ordinary agreement between parties who trust each other, that is not required.

Collecting from somebody else

The task with genuine friction, and the one worth paying for once it recurs.

What it needs: send to an email address, guide the signer through fields, return a completed copy to both parties, and tell you when it happened.

What makes it worth the price is the last two — the signer needing no account, and the automatic return — because the alternative is a chain of attachments where somebody prints, signs, photographs and sends back a crooked image.

Where it stops: identity. Knowing an email address received the document is not knowing who signed it, and the tools that address this cost considerably more.

When the signature must hold up

The requirement comes from outside, and this is the part to establish before choosing anything.

Some documents have prescribed forms. Property, wills, certain corporate filings, some employment matters — the rules differ by jurisdiction and by document, and an electronic signature that is fine for a services agreement may not be acceptable.

Where a regulator, a lender or a counterparty specifies a method, that specification is the answer. Ask them rather than choosing.

And where a dispute is genuinely plausible, what matters is the audit trail: what was sent, to whom, when it was opened, what was signed, and evidence the document was unchanged. That is a product category and it is priced as one.

What to check before buying

Whether the signer needs an account. The commonest reason a signature does not come back.

What the completed document contains — the signature, or the signature plus a certificate of completion, which is the part that matters if it is ever questioned.

Where documents rest and for how long. Signed agreements are records with long lives.

And the volume limit. Most plans price by envelopes or documents per month, and the step is easy to cross in a busy period.

The version most small firms need

Free tier or lowest paid tier of a mainstream service, plus the operating system for anything arriving to be signed.

A handful of documents a month sits inside most free allowances, and the paid step is worth taking when the allowance becomes the constraint rather than in anticipation.

And a folder where signed copies land, which is the part people skip and the reason signed agreements cannot be found two years later.

What people do instead, and why it mostly works

Print, sign, photograph, send back.

Ugly, and legally adequate for a large share of ordinary commercial agreements where both parties intend to be bound and neither will dispute it.

The costs are practical rather than legal: crooked images, missing pages, a signature on page four with no record that pages one to three were the ones agreed.

Which is why the paid tools earn their place through completeness rather than through validity — they return the whole document, in order, with a record attached.

The record after signing

The part nobody plans and everybody eventually needs.

A signed agreement is a document with a life of years. It belongs with the other records rather than only inside the signing tool.

Download the completed copy and file it somewhere that is not the vendor's account, because a subscription that lapses takes access with it — and a signed agreement you cannot produce is close to no agreement at all.

One folder, named by counterparty and date. Two minutes per document, and it is the difference between finding something in a minute and reconstructing it from email.

The free tier that is enough

For a firm signing a handful of documents a month, most mainstream services have an allowance that covers it.

The limit is usually documents or envelopes per month, and crossing it occasionally is a reason to notice rather than to upgrade — the step is easy to take and hard to reverse.

Where you cross it every month, the paid tier is honest. Where you crossed it once in a busy quarter, it was a busy quarter. For another point of comparison, consult Obsidian.

The short version

• Three tasks share the name and only one reliably needs software: collecting a signature from somebody else
• Signing something sent to you is built into both major operating systems and needs no account
• Collecting is worth paying for because the signer needs no account and the completed copy returns automatically
• Knowing an email address received a document is not knowing who signed it, and identity verification costs considerably more
• Where the signature must hold up, the requirement comes from a regulator, lender or counterparty — ask them rather than choosing
• Check whether the signer needs an account, what the completed file contains, where documents rest, and the monthly volume limit
