North Carolina General Statutes Chapter 58. Insurance § 58-71-135. Deposit for defendant admitted to bail authorizes release and cancellation of undertaking

When the defendant has been admitted to bail, he, or another in his behalf, may deposit with an official authorized to take bail, a sum of money, or nonregistered bonds of the United States, or of the State, or of any county, city or town within the State, equal in market value to the amount of such bail, together with his personal undertaking, and an undertaking of such other person, if the money or bonds are deposited by another. Upon delivery to the official in whose custody the defendant is of a certificate of such deposit, he shall be discharged from custody in the cause.

When bail other than a deposit of money or bonds has been given, the defendant or the surety may, at any time before a breach of the undertaking, deposit the sum mentioned in the undertaking, and upon such deposit being made, accompanied by a new undertaking, the original undertaking shall be canceled.
