Laura Milnor Iverson mentioned on Monday’s post something about California law and Certificates of Authenticity. She was right–partially. California law does require COAs, but only with the sale of multiples or fine prints.
This site, which says several other states have similar laws, outlines the guidelines for the use of COAs with respect to the sale of multiples and fine art prints in California.
Please note that I am not an attorney. If you are selling multiples, you’d better look into your state laws to see if COAs are required with each sale.
