   "q": "How do I get the Texas Form 503 - Assumed Name Certificate (entities)?",
   "a": "The blank Form 503 is free to download from the Texas Secretary of State, and you can fill it in and file it yourself directly with the State (online through SOSPortal, by mail, or in person) without paying us. Filing is not free: the State charges a $25 filing fee however you file (Tex. Bus. & Com. Code §71.155(b)). Or fill it in online here: pay $4.99 one-time with Stripe, answer the guided questions, and download your filled-in PDF."
