Expert writing Tips
Best practice
When including a "signature date" on a document, ensure it is clearly written and placed directly adjacent to the signature to avoid any ambiguity regarding when the signature was applied.
Common error
Don't assume the "signature date" is the same as the effective date of an agreement. The effective date is when the agreement becomes legally binding, which might be a future date explicitly stated in the document, and should not be assumed to be the "signature date".
