North Carolina General Statutes Chapter 47. Probate and Registration § 47-17.2. Assignments of mortgages, deeds of trust, or other agreements pledging real property as security

It shall not be necessary in order to effect a valid assignment of a note and deed of trust, mortgage, or other agreement pledging real property or an interest in real property as security for an obligation, to record a written assignment in the office of the register of deeds in the county in which the real property is located. A transfer of the promissory note or other instrument secured by the deed of trust, mortgage, or other security interest that constitutes an effective assignment under the law of this State shall be an effective assignment of the deed of trust, mortgage, or other security instrument. The assignee of the note shall have the right to enforce all obligations contained in the promissory note or other agreement, and all the rights of the assignor in the deed of trust, mortgage, or other security instrument, including the right to substitute the trustee named in any deed of trust, and to exercise any power of sale contained in the instrument without restriction. The provisions of this section do not preclude the recordation of a written assignment of a deed of trust, mortgage, or other security instrument, with or without the promissory note or other instrument that it secures, provided that the assignment complies with applicable law.
