This court granted certiorari to address two issues raised by Petitioners Holly Bree-den Connell and Vic E. Breeden, III (Petitioners). 1 First, Petitioners argue that the probate court incorrectly applied both the “insane delusion” and the Cunningham 2 elements tests for testamentary capacity and improperly merged the insane delusion test with the Cunningham elements test. Second, Petitioners challenge whether the probate court erred when it denied their motion to dismiss Vic E. Breeden (Breeden Sr.) and Holly Breeden Connell (Connell) as parties based on an improper application of the Dead Man’s Statute. 3 We now hold that the probate court correctly applied the two exclusive tests for testamentary capacity to find that the testator, Spicer Breeden, was of sound mind at the time he executed the holographic will. In addition, we hold that the probate court did not abuse its discretion when it denied Petitioners’ motion to dismiss Bree-den Sr. and Connell as parties, thus precluding their testimony under the Dead Man’s Statute.
I. FACTS AND PROCEDURAL HISTORY
This case involves a contested probate of a handwritten (holographic) will executed by Spicer Breeden, the decedent. Mr. Breeden died in his home on March 19, 1996, from a self-inflicted gunshot wound two days after he was involved in a highly publicized hit- and-run accident that killed the driver of the other vehicle.
Upon entering the decedent’s home following his suicide, the Denver police discovered on his desk a handwritten document that read: “I want everything I have to go to Sydney Stone— ‘houses,’ ‘jewelwry,’ [sic] stocks[,] bonds, cloths [sic]. P.S. I was Not Driving the Vehical— [sic].” At the bottom of the handwritten document, the decedent printed, “SPICER H. BREEDEN” and signed beneath his printed name.
Sydney Stone (Respondent) offered the handwritten document for probate as the holographic will of the decedent. The decedent had previously executed a formal will in 1991 and a holographic codicil leaving his estate to persons other than Respondent. Several in
On September 3-6, 1996, a hearing was held on the petition for formal probate. Both parties presented evidence in the form of testimony of factual and expert witnesses, handwriting samples, and other documents. On September 26, 1996, the probate court formally admitted the decedent’s holographic will to probate. The court made several findings based on the evidence presented. First, the court found that the decedent used cocaine and alcohol for several years prior to his death, based on the testimony of his friends Jennifer Chelwick and Michael Crow. Relying on the autopsy report and testimony from the decedent’s sister, the court found that the decedent used alcohol and cocaine on the evening of March 17 and between March 17 and 19, and that substantial alcohol was consumed proximate to the time of death. Based on the testimony of a number of the decedent’s friends, the court found that the decedent’s moods were alternately euphoric, fearful, and depressed, and that he was excessively worried about threats against himself and his dog from government agents, friends, and others.
In addition, the probate court considered the testimony of a number of expert witnesses, including two forensic toxicologists, two forensic psychiatrists, a forensic document examiner, and two handwriting experts. After considering conflicting evidence from the various expert witnesses, the court concluded that the decedent possessed the motor skills necessary to write his will and that 'his handwriting on the holographic will was unremarkable when compared to other writing exemplars. The court also considered the testimony of the decedent’s friends Ken McSpadden and Rick Eagan, who testified that in the two weeks prior to his death, the decedent had indicated to each of them in separate conversations that he did not intend to leave his estate to his family. 5
After considering the evidence, the probate court found that Petitioners did not prove by a preponderance of the evidence that, because of the decedent’s chronic use of alcohol and drugs or their use between March 17 and 19, he was not of sound mind when he executed the holographic will. In addition, the probate court held that the stress and anxiety that compelled the decedent to commit suicide did not deprive him of testamentary capacity. The court also found that the decedent’s insane delusions regarding his friends, government agencies, and others, did not affect or influence the disposition of his property. In reaching the conclusion that the decedent was of sound mind at the time he executed the will, the probate court relied on the will itself, which evidenced a sufficient understanding of the general nature of his property and the disposition under the will, the testimony of two doctors regarding the decedent’s motor skills at the time he wrote the will, evidence that the decedent had omitted his father and sister from his will in the past, and testimony from two friends that indicated the decedent had been considering revising his will in the future.
Petitioners appealed to the court of appeals, asserting that the probate court erred by applying and merging both tests for sound mind contained in Colorado Jury Instruction 34:9 and by refusing to dismiss Connell and Breeden Sr. as parties to the case, thus precluding their testimony under the Dead Man’s Statute. The court of appeals affirmed the decision of the probate court, holding that the probate court order, when read in its entirety, indicated that the probate court correctly applied the appropriate tests for sound mind and correctly applied the Dead Man’s Statute to find that Holly Breeden Connell and Vic E. Breeden should not be dismissed as parties. See In re Breeden, No. 96CA2012 (Colo.App. July 2, 1998) (not selected for official publication).
We granted certiorari to address whether the probate court correctly applied the insane delusion and
Cunningham
elements
II. TESTAMENTARY CAPACITY
Underlying Colorado’s law of wills is the fundamental concept of freedom of testation; namely that a testator “may dispose of his property as he pleases, and that [he] may indulge his prejudice against his relations and in favor of strangers, and that, if he does so, it is no objection to his will.”
Lehman v. Lindenmeyer,
Until 1973, the proponents of a will assumed the burden of proving that the testator had testamentary capacity at the time he executed a will. However, in 1973, the legislature shifted this burden to the contestants of a will.
See
Ch. 451, sec. 1, § 153-13-407, 1973 Colo. Sess. Laws 1538, 1576 (codified as amended at § 15-12-407, 5 C.R.S. (1999)). Under section 15-12-407, once a proponent of a will has offered prima facie proof that the will was duly executed, any contestant then assumes the burden of proving a lack of testamentary capacity, including a lack of sound mind, by a preponderance of the evidence.
See id.; see also In re Estate of Olschansky,
A. The Cunningham Test
We initially defined sound mind as having sufficient understanding regarding “the extent and value of [one’s] property, the number and names of the persons who are the natural objects of [one’s] bounty, their deserts with reference to their conduct and treatment toward [oneself], their capacity and necessity, and that [one] shall have sufficient active memory to retain all of these facts in [one’s] mind long enough to have [one’s] will prepared and executed.”
Lehman,
After
Lehman,
this court further refined the test for sound mind in 1953 in the landmark case
Cunningham v. Stender,
when we held that mental capacity to make a will requires that: (1) the testator understands the nature of her act; (2) she knows the extent of her property; (3) she understands the proposed testamentary disposition; (4) she knows the natural objects of her bounty; and (5) the will represents her wishes.
B. The Insane Delusion Test
This court has also held that a person who was suffering from an insane delusion at the time he executed the will may lack testamentary capacity. We first defined an insane delusion in 1924 as “a persistent belief in that which has no existence in fact, and which is adhered to against all evidence.”
In re Cole’s Estate,
We also have addressed the issue of the causal relationship necessary between an individual’s insane delusion and his capacity to contract.
See Hanks v. McNeil Coal Corp.,
[o]ne may have insane delusions regarding some matters and be insane on some subjects, yet [be] capable of transacting business concerning matters wherein such subjects are not concerned, and such insanity does not make one incompetent to contract unless the subject matter of the contract is so connected with an insane delusion as to render the afflicted party incapable of understanding the nature and effect of the agreement or of acting rationally in the transaction.
Id.
at 585,
The
Hanks
case sets out a standard for the requisite causal connection between insane delusions and contractual capacity that is equally applicable to testamentary capacity. A number of other courts have applied a similar standard in the context of testamentary capacity by phrasing the inquiry as whether the delusion
materially
affects the contested disposition in the will.
See Akers v. Hodel,
Based on Colorado precedent and the persuasive authority from other jurisdictions discussed above, we hold that before a will can be invalidated because of a lack of testamentary capacity due to an insane delusion, the insane delusion must materially affect the disposition in the will.
C. Cunningham and Insane Delusion Tests Are Not Mutually Exclusive
As the preceding case law indicates, the Cunningham and the insane delusion tests for sound mind have developed independently of each other.
The
Cunningham
test is most commonly applied in cases in which the objectors argue that the testator lacked general testamentary capacity due to a number of possible causes such as mental illness, physical infirmity, senile dementia, and general insanity.
See, e.g., White v. White,
The insane delusion test ordinarily involves situations in which the testator, although in possession of his general faculties, suffers from delusions that often take the form of monomania or paranoia.
9
See, e.g., Davis v. Davis,
As such, the
Cunningham
and insane delusion tests, although discrete, are not mutually exclusive. In order to have testamentary capacity, a testator must have a sound mind. In Colorado, a sound mind includes the presence of the
Cunningham
factors
and
the absence of insane delusions that materially affect the will. As noted above, insane delusions are often material to the making of the will, and thus will defeat testamentary capacity.
See Akers v. Hodel,
Accordingly, we hold that an objector may challenge a testator’s soundness of mind based on both or either of the Cunningham and insane delusion tests.
D. The Jury Instruction
Instruction 34:9 of the Colorado Jury Instructions is consistent with this holding. The Instruction informs the jury that:
A will which was executed at a time when the person making the will lacked testamentary capacity is not valid and is not entitled to be admitted to probate. (name of alleged testator) 10 lacked testamentary capacity if it is proved that (he)(she) ... (was not of sound mind) at the time the will was ... executed.
(A person is not of sound mind if, when executing a will, [that person is afflicted with an insane delusion that affects or influences the dispositions of property made in the will] [or][that person does not understand all of the following:.
1. That he or she is making a will;
2. The nature and extent of the property he or she owns;
3. How that property will be distributed under the will;
4. That the will distributes the property as he or she wishes; and
5. Those persons who are the natural ones to receive his or her property.])
CJI-Civ. 4th 34:9 (italics, brackets, and parentheses in original).
The definition of an insane delusion is contained in Colorado Jury Instruction 34:10, which defines it as “a persistent belief, resulting from illness or disorder, in the existence or non-existence of something which is contrary to all evidence.” CJI-Civ. 4th 34:10.
The structure and wording of Jury Instruction 34:9 preserves the discrete nature of- these two tests for sound mind. The Instruction employs the use of the word “or” in brackets and sets off each test from the other by enclosing them each in brackets to clearly present the tests -as independent. See CJI-Civ. 4th 34:9. In addition, note two of the “Notes on Use” following Instruction 34:9 states that one should “use whichever parenthesized and bracketed portions of the instruction are appropriate in light of the evidence in the case.” Id. at n. 2 (emphasis added). This language indicates that either or both tests may be applicable to a particular will and more than one portion may apply to any given case. A plain reading of the Instruction, and particularly the use of the word “or,” leads to the conclusion that, while exclusive, an objector to a will may challenge a testator’s capacity based on both or either of these two tests.
E. Probate Court Decision
Petitioners argue that the trial court erred with respect to its analysis of the Cunningham and the Insane Delusion tests. They contend that because this ease involves insane delusions, the insane delusion test should have been exclusively applied. By extension, they argue that the Cunningham test should not have been applied at all. Based upon this logic, Petitioners argue that the trial court erred by: (1) applying both the Cunningham and the insane delusion tests in a case which involves only insane delusions; and (2) merging the Cunningham and the insane delusion tests.
Upon reviewing the decision of the probate court, we hold that the court correctly applied these two exclusive tests for testamentary. capacity to find that the decedent was of sound mind at the time he executed his holographic will. The court found that the decedent had used alcohol and cocaine for several years prior to his death, had used alcohol and cocaine between March 17 and 19, suffered from mood swings, and worried excessively about threats against his and his dog’s life. Despite these adverse findings, the- court found that the decedent was of sound mind.
First, the court applied the Cunningham test and found that the decedent: (1) could index the major categories of the' property comprising htó estate; (2) knew his home and rental addresses; and (3) identified the devi-see by name and provided her current address. The court noted that the will was “legible, logical in content, and reasonably set[] out [the decedent’s] intent.” In addition, the probate court considered the testimony of handwriting experts that indicated that at the time the decedent wrote the will, he was in command of his motor skills and his handwriting was unremarkable when compared to other exemplars. Based upon these factors, the trial court found that the decedent met the Cunningham test for sound mind.
Then, the probate court applied the insane delusion test to hold that although the decedent was suffering from insane delusions at the time he executed his will, “[his] insane delusions did not affect or influence the disposition of property made in the will.”
Cf. In re Haywood’s Estate,
The Petitioners also contend that the trial court erred by “merging” the Cunningham and insane delusion tests, and point for support to the probate court’s statement that the “Mbjeetors did not prove by a preponderance of the evidence that [the decedent’s insane delusions] caused [him] to misapprehend the nature of his property, the identities of or his relationship with objectors, or the manner in which he wished to dispose of his property at the time the will was written.” Our decision that the probate court correctly applied both tests for sound mind, by implication, holds that the court did not incorrectly merge the two tests. Although, at times, the probate court merged language from the Cunningham and insane delusion tests, the decision as a whole indicates that the court thoroughly analyzed all of the evidence presented and applied each of the tests to find that the decedent was of sound mind.
In sum, the probate court order reflects that the court thoroughly considered all of the evidence presented by the parties and concluded that (1) the testator .met the Cunningham test for sound mind and (2) the insane delusions from which the decedent was suffering did not materially affect or influence his testamentary disposition.
III. PROBATE COURT’S DENIAL OF PETITIONERS’ MOTION TO DISMISS BREEDEN SR. AND CONNELL
Petitioners contend that the probate court erred when it denied their motion to dismiss Breeden Sr. 12 and Connell as parties so that they could testify to conversations with the decedent arguably barred by the Dead Man’s Statute. Petitioners argue that the probate court erred because neither Breeden Sr. nor Connell had a disqualifying direct interest to justify an invocation of the Dead Man’s Statute. We now hold that the probate court did not err when it denied Petitioners’ motion to dismiss two of the three named parties because the Dead Man’s Statute bars their testimony as parties to the suit, and therefore, dismissing them as parties on the first day of the hearing would have resulted in unfair surprise and potential prejudice to Respondent.
A. The Dead Man’s Statute
Under section 13-90-101, 5 C.R.S. (1999), all persons with an interest in a cause of action are presumed competent to testify.
The Dead Man’s Statute states:
No party to any civil action, suit, or proceeding or person directly interested in the event thereof shall be allowed to testify therein of such person’s own motion or in such person’s own behalf ... when any adverse party sues or defends as the ... heir, legatee, or devisee of any deceased person....
§ 13-90-102(1), 5 C.R.S. (1999) (emphasis added).
We have interpreted this statute to hold that a potential witness is disqualified if, at the time of the proceedings, he is a party to the suit,
13
or he will gain or lose by the direct legal operation of the judgment, and his testimony is being offered against an heir, legatee, devisee, or other person listed in the statute.
See In re Eder’s Estate,
In the present case, Petitioners Breeden Sr. and Connell were parties to the suit; 14 accordingly, their testimony was barred by application of the Dead Man’s Statute.
B. The Probate Court Did Not Err When It Denied Petitioners’ Motion to Dismiss Breeden Sr. and Connell
A petition for formal probate of the decedent’s will was filed on April 5, 1996. On June 3,1996, Petitioners filed an objection to petition for formal probate. On September 3, 1996, the first day of the probate hearing, Petitioners filed a motion to dismiss Breeden Sr. and Connell as parties to the suit. The trial court denied the motion. In denying the motion, the probate court stated three reasons for its decision: (1) the motion was filed on the first day of the hearing; (2) the parties would be barred from testifying under the Dead Man’s Statute regardless; and (3) having identified themselves as beneficiaries and having objected to the probate of the decedent’s will, the parties should not be permitted to disclaim their interest. 15
The probate court’s denial of the motion to dismiss filed by Petitioners Breeden Sr. and
We hold that the probate court did not abuse its discretion when it denied Petitioners’ motion to dismiss. Despite having sufficient time to prepare for the probate hearing, Petitioners chose to wait until the day of the hearing to file a motion to dismiss two of the three named parties to the suit.
16
This motion was a surprise to both the court and opposing counsel. As such, the trial court correctly noted that if the motion were to be granted the result would be unfair surprise and potential prejudice.
See generally Todd v. Bear Valley Village Apts.,
Accordingly, we hold that the probate court did not abuse its discretion when it denied Respondents’ motion to dismiss Bree-den Sr. and Connell as parties. Because Breeden Sr. and Connell were parties, the probate court correctly excluded their testimony regarding conversations with the decedent pursuant to the Dead Man’s Statute.
IV. CONCLUSION
We hold that the probate court correctly applied the two exclusive tests for testamentary capacity to find that the testator, Spicer Breeden, was of sound mind at the time he executed the holographic will. Additionally, we hold that the probate court did not abuse its discretion when it denied Petitioners’ motion to dismiss Breeden Sr. and Connell as parties, thus precluding their testimony as parties under the Dead Man’s Statute. Accordingly, we affirm the decision of the court of appeals upholding the probate court’s ruling that the decedent was of sound mind and upholding the probate court’s denial of Petitioners’ motion to dismiss Breeden Sr. and Connell.
Notes
.Vic E. Breeden, the decedent’s father, was a named party in the contested probate proceeding and in the appeal to the court of appeals. However, on April 19, 1999, Petitioners filed a motion for amendment to caption and suggestion of death, stating that on April 16, 1998, Vic E. Breeden died, leaving Holly Breeden Connell and Vic E. Breeden, III, as his heirs. Accordingly, on May 3, 1999, the court granted the motion to amend the caption to reflect Holly B. Connell and Vic E. Breeden, III, as Petitioners.

There's an additional reason ... that even if Mr. Breeden, Sr. and Holly B. Connell were permitted to be dismissed at this point ... they still retain their status as ... heirs ... who ... would have taken if there had been no will....

Accordingly, I'm going to deny the motion to dismiss these individuals from the case.
