If an attorney files an amicus curiae brief in a case in a New York court and receives payment does he have to disclose the payment to the court?

In New York, if an attorney files an amicus curiae brief in a case in a New York court (either Appellate Division or the New York Court of Appeals), and receives compensation therefor, does he have to disclose anything re the compensation to the court (e.g., that he's being compensated, how much, who the client is, etc.)?
