(a) To be effective, a disclaimer must:
(1) be in writing;
(2) declare the disclaimer;
(3) describe the interest or power disclaimed;
(4) be signed by the person making the disclaimer; and
(5) be delivered or filed in the manner provided by Subchapter C.
(b) A partial disclaimer may be expressed as a fraction, percentage, monetary amount, term of years, limitation of a power, or any other interest or estate in the property.
(c) A disclaimer is irrevocable on the later of the date the disclaimer:
(1) is delivered or filed under Subchapter C; or
(2) takes effect as provided in Sections 240.051-240.056.
(d) A disclaimer made under this chapter is not a transfer, assignment, or release.
(e) A disclaimer of an interest in property made by an individual must contain a statement under penalty of perjury regarding whether the disclaimant is a child support obligor whose disclaimer is barred under Section 240.151(g). An individual's failure to include the statement does not invalidate a disclaimer if the disclaimer is not barred under Section 240.151(g).
