S.C. Code Ann. § 30-7-50: Manner in which assignment shall be executed and probated.

Any assignment to be entitled to be recorded as provided in Section 30-7-40 shall be in writing and witnessed as mortgages of real property are required to be witnessed and shall not be probated when it is upon, or attached to, the original mortgage itself, but when it is upon a separate piece not attached to the original mortgage itself then it shall be probated in the same way as is now provided by law for the probating of mortgages of real property. Assignment of mortgage forms shall include the name of the mortgagor and the name and address of the mortgagee and the book, page, and date of recording of the original mortgage, and may include a toll free number for the assignee if such a number is available.
