This document is a California Form 593-C, which is a Real Estate Withholding Certificate. It allows a seller of California real estate to certify exemptions from real estate withholding requirements. The form has four parts: seller information, certifications that fully exempt from withholding, certifications that may partially or fully exempt, and the seller's signature. Checking boxes in Part II or III can allow full or partial exemption from the default 3 1/3% withholding on the sales price of California real estate.
