Counter check is a term that means to verify or examine a document or evidence that has already been verified once before. Antonyms for the word "counter check" are acceptance, approval, and validation. Acceptance refers to the act of receiving something willingly or without resistance. Approval, on the other hand, signifies a positive evaluation or commendation of something. Validation implies the confirmation of something that is already considered true or correct. Collectively, these words represent the opposite of counter check in that they describe an attitude of trust and faith in something, rather than the need to double-check or examine it thoroughly before accepting it.
