Tex. Tax Code § 25.11 — UNDIVIDED INTERESTS

(a) Except as provided by Section 25.12 of this code and by Subsection (b) of this section, a property owned in undivided interests may be listed jointly in the name of all owners of undivided interests in the property or in the name of any one or more owners. (b) An undivided interest in a property shall be listed separately from other undivided interests in the property in the name of its owner if the interest is described in a duly executed and recorded instrument of title and the owner files with the appraisal office before May 1 a written request for separate taxation on a form furnished for that purpose together with proof of ownership and of the proportion his interest bears to the whole. After an undivided interest qualifies for separate taxation, the qualification remains effective in subsequent tax years and need not be requested again. However, the qualification ceases when ownership is transferred or when any owner files a request to cancel separate taxation. (c) Within 30 days after an owner qualifies for separate taxation or cancels a qualification, the chief appraiser shall deliver a written notice of the qualification or cancellation to the other owners.
