noun
nonrecognition; refusal to acknowledge
Formal or legal term for the act of not recognizing or refusing to acknowledge something, such as a claim, right, or fact. Rare in everyday conversation.

不承認 is a more standard term for disapproval or non-approval, often used in official settings. 不認承 is less common and may carry a nuance of refusing to acknowledge existence or validity.
Compound of 不 (not) + 認承 (recognition, acknowledgment). 認承 itself is a rare compound of 認 (recognize) and 承 (accept). The exact historical derivation is uncertain; the term appears mainly in formal or legal documents.
