From wax seals in medieval times to electronic signatures in the cloud, the way people sign agreements has always been chasing the same goal: security and trust in the deal-making itself.
A signature builds relationships on legal ground. Today, whether you're onboarding a new employee or signing a year-long vendor deal, that signature isn't optional. This guide walks through what contract signing actually involves, what makes a signed contract legally binding, the best practices for taking it to execution smoothly, and what that mysterious "Its:" line is actually doing on your signature block.
Contract signing is the act of adding signatures to a contract to accept the terms and conditions it contains. It formalizes a business relationship into a legally binding agreement, and it's what gives a court something to point to if a dispute over the contract signatory's authority ever comes up.
You'll sometimes see contract signing referred to as "executing" an agreement, particularly in formal legal drafting, or occasionally "ratifying" one when board or government approval is involved. All three describe the same underlying act: turning a negotiated draft into an enforceable commitment.
A signature is necessary, but it's not the whole story. A contract is generally enforceable when it contains a specific set of elements, and missing one can make even a signed document unenforceable:
Miss any of these, and the signature at the bottom doesn't do as much work as people assume it does.

Signing is an intentional act, proof that everyone involved consented to enter the relationship. Without a signed contract, disputes get murky fast. There's no binding proof of intent to follow the terms laid out.
Beyond enforceability, signing also triggers what happens next: vendor onboarding, invoicing, project kickoffs, whatever the agreement was actually for. A contract that sits unsigned doesn't just carry legal risk, it stalls the business on the other side of it.
If you've ever looked at a signature block reading "By: ___ Its: CEO" and wondered what that second line is doing there, it's identifying the capacity someone is signing in on behalf of the company as its CEO, not as a private individual.
Without that line, a signatory could later be argued to have signed personally, potentially making them individually liable for obligations meant to bind the company. It's a small line that does a lot of legal work, which is exactly why it shows up in nearly every commercial signature block, right under the name and title.
The importance of identifying signing capacity is also reflected in UK government guidance on executing deeds, which explains that the capacity in which a person signs should be clear and that evidence of their authority may be required.
Wet ink signatures
It involves signing a printed copy with a pen, then circulating it by mail or in person. Quick for face-to-face negotiation, but messy once parties are spread out. Some document types, like wills, real estate deeds, and notarized filings, still require it in many jurisdictions.
Electronic signatures
It let parties sign by typing or drawing a signature on a screen. They're fast and eliminate logistics, though not universally accepted. The ESIGN Act (US), eIDAS (EU), and PIPEDA (Canada) each set their own rules. For a deeper look at the different formats, see our breakdown of types of electronic signatures.
In the U.S., the Electronic Signatures in Global and National Commerce Act (ESIGN) provides that a contract or signature cannot be denied legal effect simply because it is in electronic form.
In the EU, Article 25 of eIDAS similarly states that electronic signatures cannot be denied legal effect solely because they are electronic, while qualified electronic signatures have the same legal effect as handwritten signatures.
Digital signatures are a more advanced form of e-signature using cryptographic technology to authenticate signatories and protect document integrity, often paired with a digital signature requirement in higher-risk deals. Our comparison of wet ink vs. e-signatures covers the practical trade-offs between all three methods in more depth.
For contracts with multiple signatories, most platforms also let you choose between sequential signing (each party signs in a defined order, useful when internal approval has to happen before a counterparty signs) and parallel signing (everyone signs at once, faster for low-risk agreements where order doesn't matter).
Identify the signatories and confirm each has legal authority to sign on their organization's behalf. Signing authority matters as much as the signature itself. For example, the U.S. Federal Acquisition Regulation requires contracting officers to ensure that a contractor's signatories have authority to bind the contractor.
Determine the signing order, following organizational hierarchy or plain scheduling logistics.
Choose your signing method based on legal requirements, urgency, and how spread out your parties are.
Set a signing timeline with reminders so nobody misses a deadline.
Manage document versions. Keep everyone on the latest draft with a clear naming convention, or let a contract lifecycle management platform handle version control automatically.
Confirm legal compliance. Also read: the ultimate guide to contract compliance.
1. Store it securely. 71% of companies can't locate at least 10% of their contracts, a genuinely avoidable problem with a proper repository and an audit trail tracking every access and edit.
2. Track obligations and performance against agreed milestones, ideally tied to the contract's obligation management rather than a personal calendar reminder.
3. Manage renewals and terminations. Learn about the contract renewal process, strategy, and best practices.
4. Run regular audits on compliance, performance, and financial terms.
The stakes for skipping this stage are real. World Commerce & Contracting research found that businesses experience average value erosion of 8.6% annually through poor contract management, equivalent to almost 9% of annual revenue.
Sign the right version. Standardize your naming convention or use a CLM that auto-versions edits.
"Version control is key to contract risk management. Using old agreements is dangerous, primarily because existing agreements likely contain negotiated terms." — Sterling Miller, CEO and Senior Counsel, Hilgers Graben PLLC
Outline every signatory's capacity in the signature block, exactly what the "Its:" line is for.
Carefully review termination and dispute resolution clauses.

Keep an original copy of the signed agreement and all supporting documents, stored in a single contract repository rather than scattered inboxes.
Slow down. Don't sign under pressure. If verbal agreements were made earlier, get them written into the document first.
Legal teams that move a high volume of standard agreements to self-service, like clickwrap for vendor or terms-of-use acceptance, often see the workload drop sharply.
Ekank Mehra, In-House Counsel at Headout, described the effect plainly: it helped "reduce our contracting work by around 60%," freeing the team from re-executing near-identical agreements one signature at a time.
SpotDraft's e-signature tool collects legally binding signatures compliant with ESIGN, eIDAS, and ECA, with bulk signing for high-volume documents like offer letters and MSAs. Automated workflows route contracts for approval based on rules you set, and once approved, documents move to the right signatories in order automatically.
One Capterra reviewer, a Head of Systems and Knowledge, put it this way:
SpotDraft is "extremely flexible so you can build out processes or flows that suit your business." Underneath all of it sits contract lifecycle management that keeps version history and audit trails intact from first draft to final signature.
Signing looks like the simple part of a contract's life, a single click or a pen on paper, but it's the step that turns negotiated language into an enforceable commitment. Get the signatory, the capacity, and the version right, and the signature does exactly what it's supposed to. Get any of those wrong, and the dispute usually starts right there.
