Expert writing Tips

Best practice

Use "signatory" when referring to the entity that signed the agreement, not to the agreement itself. The agreement is the document signed.

Common error

Avoid using "signatory" when you actually mean "signature". "Signatory" refers to the person or entity signing, while "signature" is the actual written name.
