The New York Attorney Admission Sponsoring Affidavit (NYASA) is a document used by law firms in New York to certify that an attorney has the qualifications to practice law in the state. The affidavit is signed by the lawyer’s sponsoring attorney and submitted to the New York Supreme Court for approval. By signing the affidavit, the sponsoring attorney attests to the lawyer’s competency and ability to practice law in the state. There are two types of New York Attorney Admission Sponsoring Affidavit. The first is an Affidavit of Sponsorship for Admission to the Bar of the State of New York. This affidavit is used when an attorney has already been admitted to the bar of another state and is seeking admission to the New York bar. The second type of affidavit is an Affidavit of Sponsorship for Admission to Practice Law in the State of New York. This affidavit is used when an attorney has not yet been admitted to the bar of another state and is seeking admission to the New York bar.
