In most states, LegalZoom will email your prepared DBA application to you for signature. For your convenience, we'll also send a duplicate copy by U.S. mail. When we receive your signed application, we will file your DBA application with the proper government office. In states that do not require your signature (AK, CO, FL, HI, MO, OK and WA), we will electronically file your DBA application directly. Once your materials are submitted, the document review period varies depending on the state or county where you file. Most orders take about 15 business days to complete after we receive your signature.
