Texas Form 503 - Assumed Name Certificate (entities)

The Secretary of State's instructions say Form 503 is for entities such as corporations, LLCs, limited partnerships, limited liability partnerships, professional associations, and foreign entities registered with the Texas SOS. Sole proprietors and general partnerships file an assumed name certificate with their county clerk instead, not Form 503. We do not support LLLPs or series entities. If any of this describes you, please don't buy this.

How it works

Our software is a guided questionnaire. It checks your answers for format and basic consistency against the Secretary of State's published instructions and places them on the State's Form 503. It does not use an AI model to fill your form, and no person reviews your answers or your PDF. We can't tell you whether you need this filing, which entity type, counties, or term to choose, whether your name is available, or whether it infringes anyone's rights. You are responsible for checking every entry before you sign and file.
