Form 503—General Information
(Assumed Name Certificate)
The attached form is drafted to meet minimal statutory filing requirements pursuant to the relevant code
provisions. This form and the information provided are not substitutes for the advice and services of an
attorney and tax specialist.
A domestic or foreign corporation, limited liability company, limited partnership, limited liability
partnership, or other foreign filing entity that regularly conducts business or renders a professional
service in this state under a name other than its legal name (the name stated in its certificate of formation
or comparable document) must file an assumed name certificate with the secretary of state and with the
county clerk in the appropriate county. (Texas Business & Commerce Code [TBCC] § 71.103).
Effect of Filing: The effect of filing is to give notice to the public that the entity is conducting business
under that name. The filing of an assumed name shall not constitute actual use of the assumed name for
determining priority of name; nor does the filing of assumed name give the registrant any right to use the
name when contrary to the common law or statutory right of unfair competition, unfair trade practices,
common law copyright or similar law (TBCC § 71.157). Since the filing is a notice filing, the secretary
of state does not have the authority to review the name of the certificate to determine if the filing
conflicts with another name on file with this office.
Changes to Information: There is no procedure for an amendment to or correction of an assumed name
certificate. If there is a material change in the information on the certificate, a new certificate should be
filed (TBCC § 71.152). The new certificate should be filed within 60 days after the occurrence of the
events which necessitate the filing. An event that causes the information contained in a certificate to
become materially misleading includes a change in the name or form of business of the assumed name
Duration: The assumed name certificate shall be effective for a term not to exceed ten years from the
date the certificate is filed and may be renewed by filing a new certificate within six months of the
expiration of the original certificate (TBCC § 71.151). A registrant may abandon the assumed name
certificate before the expiration of the period of duration by filing an abandonment of the certificate
Noncompliance: The TBCC in sections 71.201 through 71.203 provides both civil and criminal penalties
for failure to file the assumed name certificate.
This form has been drafted for filing with the secretary of state. Assumed name certificates filed with
the county clerk must be notarized and contain original signatures. Consequently, this form does not
satisfy county filing requirements. An assumed name certificate filed with the county clerk must be sent
directly to the appropriate county clerk and not to the secretary of state.
Instructions for Form
Item 1—Assumed Name: The assumed name certificate must state the assumed name under which
the business or professional service is or is to be conducted. An entity may conduct business or
professional services under multiple assumed names, but a separate assumed name certificate must
be filed for each assumed name. Please note that if the name entered as the assumed name in item 1
Form 503 1
is exactly the same as the legal name of the entity on file with the secretary of state, the certificate
will be rejected for failing to provide an assumed name.
Item 2—Entity Name: The assumed name certificate must contain the legal name of the entity as
contained in its certificate of formation or comparable document filed with the secretary of state. An
incorporated entity, such as a bank or trust company, whose organizational documents are not filed
with the secretary of state, would set forth the legal name of the entity as contained in its
Items 3 and 4—Type of Entity and File Number: Identify the type of entity that is filing the
assumed name. If there is not a check box that applies to the entity, check “other” and then specify
the type of entity in the space provided. It is recommended that the file number, if any, assigned by
the secretary of state be provided to facilitate processing of the document.
Item 5—Jurisdiction: The certificate must state the jurisdiction of formation of the entity filing the
assumed name certificate.
Item 6—Principal Office Address: Provide the street or mailing address of entity’s principal
Item 7—Period of Duration: An assumed name certificate is effective for a term not to exceed a
period of ten years from the date of filing the certificate. Check the applicable box to specify the
duration which the entity determines should be the duration of the filing of the assumed name
certificate. The entity may opt to make the duration the maximum period of ten years, a period of
less than ten years or until a date certain which date is not more than ten years from the date of
Item 8—County or Counties in which the Assumed Name Used: The assumed name certificate
is required to state the counties in which the assumed name will be used. If the entity will
potentially use the assumed name in all counties in Texas, check the box for “All.” If the entity
wishes to exclude certain counties but will use the assumed names in most counties, check the box
for “All counties with the exception of the following counties” and list the excluded counties. If the
entity will only conduct business in specific counties, check the box for “Only the following
counties” and list those specific counties.
County Level Filings: An assumed name certificate will not be required to be filed in each county
listed or each county in which the entity conducts business under the assumed name.
An entity that has a registered office address in Texas files an assumed name certificate in the office
of the county clerk of the county in which the entity maintains its principal office address in Texas.
If the entity does not have a principal office address in Texas, the assumed name certificate would be
filed in the county in which the entity maintains its registered office address.
A Texas entity that is not required to have or that does not maintain a registered office address in
Texas, such as a Texas limited liability partnership or bank, would file its assumed name certificate
in the county in which the entity’s principal office is located.
An entity that is not incorporated or organized under Texas law and that does not maintain a
registered office address in Texas would file its assumed name certificate in the county in which the
entity’s principal office in Texas is located and in the county in which it maintains its principal place
Form 503 2
of business, if its principal place of business in Texas is not in the same county where the principal
office is located.

partner, member, manager, representative of or attorney in fact for the corporation, limited
partnership, limited liability partnership, limited liability company, or foreign filing entity. A
certificate executed by an attorney in fact shall include a statement that the attorney in fact has been
duly authorized in writing by the principal to execute the certificate. Please review the form
carefully. Pursuant to section 71.203, a person commits an offense under section 37.10, Penal
