Expert writing Tips
Best practice
Prefer using "be attested by" or "be attested to" instead of "be attested with" for better grammatical correctness and clarity. "Be attested by" indicates the source of the attestation, while "be attested to" describes what is being affirmed.
Common error
Avoid using "with" after "attested". This preposition doesn't logically connect the attestation to its source or content. Always consider if "by" (source) or "to" (content) fits better.
