Draw vs Type — which should you use?
Draw produces a unique, handwritten-style signature that looks personal and authentic. It’s ideal for contracts, letters and formal documents.
Type uses a cursive-style font to render your name. It looks clean and professional — good for approval stamps and internal documents.
Is a digital signature legally valid?
For the vast majority of everyday documents — lease agreements, freelance contracts, consent forms, approval letters, NDAs — a drawn digital signature is legally recognised in the UK (Electronic Communications Act 2000), EU (eIDAS Regulation) and US (ESIGN Act).
The exception is documents requiring a witnessed or certified signature — wills, certain deeds, some financial instruments. For these, use a certified electronic signature service like DocuSign or Adobe Sign, which provide audit trails.
📌 When in doubt about legal validity, check with the other party. Most organisations accept digital signatures for routine documents without question.
