In Texas, X died testate. The will identifies Legatee A (who is the son of X) as a beneficiary of a legacy. However, X's will is amended by "Codicil 1" which states that legatee A refuses to accept any legacy or devise under this will. The will states: "Codicil 1 is attached to this will and amends this will to the extent so provided in Codicil 1". "Codicil 1" purports to have been signed by legatee A. Legatee A brings suit against the executor of the will on grounds that Legatee A did not sign "Codicil 1". Legatee A claims the signature of Legatee A in "Codicil 1" is a forgery. Which of the following statements, if any, is correct regarding the law in Texas?
