Websites that let you create your own will are usually not law firms, though there may be some exceptions. Oftentimes these will-creation websites are founded by lawyers or have lawyers on the company board, but the website itself does not meet the legal requirements required to call itself a law firm. This means that there is no lawyer-client relationship or privilege implied in any of your dealings with the company in most cases. Some sites will offer to connect you with a lawyer, but the company itself should not be mistaken for a law firm.
