OPINION
In a dispute over the proper recipient of life insurance proceeds from a policy purchased by her ex-husband, Patsy Chapman appeals a summary judgment in favor of his daughters, Rachel K. Abbot, Treva J. Burks, and Rebecca A. Sheehan. Chapman contends that the trial court erred in granting summary judgment in favor of the daughters because genuine issues of material fact exist as to the terms of a divorce decree and the validity of a power of attorney. We conclude that the trial court properly granted summary judgment and therefore affirm.
Background
On January 16, 2002, Chapman and James Carrell Guyton executed an agreed divorce decree and divorced. The decree contains the following contractual provisions regarding alimony and insurance:
9.3 AMOUNT
[Guyton] will pay to [Chapman] $2,200.00, per month, in two payments of $1,100.00 each, as and for alimony. These payments will be payable monthly, on or before the 1st and 15th day of each month, beginning on February 1, 2002.
9.4 TERM
The payments will be payable until February 1, 2005, or [Chapman] dies, or [Chapman] remarries, whichever occurs first.
9.6 INSURANCE
As long as alimony is payable under this article, [Guyton] will keep the life insurance at Oldline Life Insurance, Policy Number 5-2063321L in full force and effect, at [Guyton’s] expense, in the face amount of $50,000.00 naming [Chapman] irrevocable beneficiary.
It is the intent of [Guyton] and [Chapman] that in the event of the death of [Guyton] during the term of the alimony contract that the entire sum of the life insurance proceeds of $50,000.00 shall be due and payable to [Chapman] in addition to those sums paid pursuant to the parties!’] monthly contractual alimony package.
Throughout 2002, 2003, and 2004, Guy-ton timely paid alimony and maintained a $50,000 life insurance policy with Chapman named as the beneficiary, in accordance with the divorce decree. On December 13, 2004, Guyton gave Chapman an alimony check for $1,100, and wrote “Final Alimony” at the bottom of the check. The December 13 alimony payment was the seventy-second alimony payment Guyton made under the decree.
On December 30, 2004, Guyton executed a statutory durable power of attorney naming Sheehan as his attorney-in-fact. See Tex. Prob.Code Ann. § 490 (Vernon 2003). On January 10, 2005, Sheehan used the power of attorney to change the beneficiary designation of the $50,000 life insurance policy. Sheehan named herself, Abbot, and Burks as the new beneficiaries of the policy. Guyton died of pneumonia the following day.
In August 2005, American General Life Insurance Company filed a petition in in-terpleader ■ against Chapman, Abbot, Burks, and Sheehan, seeking a judicial determination of the proper beneficiary of *616 the hfe insurance policy. See Tex.R. Civ. P. 43. The daughters moved for summary judgment, asserting that they were entitled to the proceeds of the insurance policy as a matter of law, or alternatively, that Chapman had produced no evidence that Guyton had breached the divorce decree by changing the beneficiary of the life insurance policy. In the motion, the daughters contend that the December 13 payment terminated Guyton’s alimony obligation under the agreement incorporated in the divorce decree, as well as his obligation to maintain a life insurance policy in favor of Chapman. The trial court granted the summary judgment without specifying the grounds, ruling that the daughters were entitled to the proceeds of the life insurance policy.
Summary Judgment
A Standard of Review
We review a trial court’s summary judgment de novo.
Valence Operating Co. v. Dorsett,
B. Contract Interpretation
“An agreed divorce decree is a contract subject to the usual rules of contract interpretation.”
Broesche v. Jacobson,
Whether a contract is ambiguous is a question of law for the court.
Heritage Res., Inc. v. NationsBank,
“A contract is ambiguous when its meaning is uncertain and doubtful or is reasonably susceptible to more than one interpretation.”
Id.
We determine whether a contract is ambiguous by looking at the contract as a whole in light of the circumstances present when the parties entered the contract.
Universal Health Servs., Inc. v. Renaissance Women’s Group, P.A.,
An ambiguity in a contract may be either patent or latent.
Id.
A patent ambiguity is evident on the face of the contract.
Id.
A latent ambiguity arises when a contract that is unambiguous on its face is applied to the subject matter with which it deals and an ambiguity appears by reason of some collateral matter.
Id.
When a contract contains an ambiguity, either patent or latent, the interpretation of the instrument becomes a fact issue.
Coker v. Coker,
C. Early Payments
Chapman contends that the term of the alimony payments in the divorce decree was from February 1, 2002 until February 1, 2005, and Guyton could not extinguish his obligations under the contract by making an early alimony payment. The contract, however, expressly states that Guyton must make alimony payments “on or before the 1st and 15th day of each month.” The plain meaning of the term “before” is “in advance” or “at an earlier time.” MeRRIAm-WebsteR’s Collegiate DigtionaRY 110 (11th ed.2003). We therefore conclude that the phrase “on or before” permitted Guyton to satisfy his alimony obligation by making payments before they were due.
See, e.g., Kennedy Ship & Repair, L.P. v. Pham,
Furthermore, the contract states that “[a]s long as alimony is payable under this article, [Guyton] will keep the life insurance at Oldline Life Insurance, Policy Number 5-2063321L in full force and effect, at [Guyton’s] expense, in the face amount of $50,000.00 naming [Chapman] irrevocable beneficiary.” The contract also states that “[i]t is the intent of [Guy-ton] and [Chapman] that in the event of the death of [Guyton]
during the term of the alimony contract
that the entire sum of the life insurance proceeds of $50,000.00 shall be due and payable to [Chapman] in
*618
addition to those sums paid pursuant to the partiesP] monthly contractual alimony package.” (emphasis added). This language plainly allows Guyton to change the beneficiary of the life insurance policy after the completion of his alimony obligation.
See Breitenfeld,
The life insurance policy also allows Guyton to change the beneficiary. The policy provides, “While the insured is alive, the owner may change the beneficiary or ownership by written notice to us. When we record the change, it will take effect as of the date the owner signed the notice, subject to any payment we make or other action we take before recording.”
Considering the contract as a whole in light of the circumstances present when the parties entered it, we hold that the contractual terms surrounding the early payment of alimony, and Guyton’s ability to change the beneficiary of the life insurance policy upon payment of the required alimony, are unambiguous.
See Breitenfeld,
D. Assignment
Chapman contends that the divorce decree contains an anti-assignment clause that prohibited Guyton from changing the beneficiary of the life insurance policy. Section 9.11 of the divorce decree states, “Neither the agreement to pay alimony nor the right to receive alimony under this article is assignable or transferable.”
The life insurance policy and the proceeds thereof, however, are not alimony. The divorce decree expressly provides that “[Guyton] will pay [Chapman] $2,200.00, per month, in two payments of $1,100.00 each, as and for alimony.” The contractual provisions regarding the life insurance policy do not refer to the policy or its proceeds as alimony. Rather, the contract separately refers to the life insurance policy and the alimony payments in the following excerpt from section 9.6:
It is the intent of [Guyton] and [Chapman] that in the event of the death of [Guyton] during the term of the alimony contract that the entire sum of the life insurance proceeds of $50,000.00 shall be due and payable to [Chapman] in addition to those sums paid pursuant to the parties[’] monthly contractual alimony package.
Because the contract is worded in such a way that it can be given a certain or definite legal meaning or interpretation, we hold that the contractual provision regarding the assignability of alimony payments is unambiguous and refers only to Guyton’s bimonthly alimony payment of $1,100.00.
See Breitenfeld,
E. Number of Payments
Chapman further contends that the divorce decree required seventy-three alimony payments, not seventy-two. Thus, according to Chapman, Guyton breached their contract by changing the beneficiary designation of the life insurance policy before satisfying his alimony obligation. It is undisputed that Guyton made only seventy-two alimony payments under the contract.
With respect to the number of payments, section 9.3 of the divorce decree provides that “[Guyton] will pay to [Chapman] $2,200.00, per month, in two payments of $1,100.00 each, as and for alimony. These payments will be payable monthly, on or before the 1st and 15th day of each month, beginning on February 1, 2002.” Section 9.4, which governs the term of the agreement further provides that “[t]he payments will be payable until February 1, 2005, or [Chapman] dies, or [Chapman] remarries, whichever occurs first.” The central issue here is whether the divorce decree required Guyton to make an alimony payment on February 1, 2005. If the contract required a February 1, 2005 payment, then seventy-three total payments were due under the contract and Guyton’s alimony obligation was not complete as of the date Sheehan changed the beneficiary designation. If no payment was due on February 1, then seventy-two total payments were due under the contract, and Guyton fulfilled his alimony obligation with the final payment made on December 13.
Standing alone, the provision requiring that alimony payments be made “until February 1, 2005” is reasonably susceptible to more than one interpretation with regard to the total number of payments due under the contract.

*620 F. Newly Discovered Evidence
Finally, Chapman contends that the trial court erred in granting summary judgment in favor of Abbot, Burks, and Sheehan because genuine issues of material fact exist with regard to the validity of the power of attorney. After the trial court granted summary judgment, Chapman moved for a new trial, asserting that she had discovered new evidence that the general power of attorney designating Sheehan as Guyton’s attorney-in-fact was a forgery. The trial court denied Chapman’s motion for new trial. Chapman now asserts that the evidence suggesting that the power of attorney was forged creates a fact issue that should have precluded the summary judgment.
A party who seeks a new trial on the ground of newly discovered evidence must satisfy the court that (1) the evidence has come to his knowledge since the trial, (2) it was not owing to want of due diligence that the evidence did not come to his attention sooner, (3) the evidence is not cumulative, and (4) the evidence is so material that it would probably produce a different result if a new trial were granted.
Jackson v. Van Winkle,
In her motion for new trial, Chapman produced the affidavit of a handwriting examiner who testified that the power of attorney in favor of Sheehan was a forgery. The trial court denied the motion, stating that Chapman failed to exercise due diligence in obtaining the new evidence, and that Chapman should have anticipated the need for expert testimony.
Chapman’s motion for new trial does not explain why she could not have obtained the new evidence before the submission date of the motion for summary judgment. Chapman has therefore failed to demonstrate that it was not owing to want of due diligence that the evidence did not come to her attention sooner.
See Jackson,
G. Conclusion
We hold that Abbot, Burks, and Shee-han established as a matter of law that Guyton discharged his obligation to pay alimony and did not breach the divorce decree by changing the beneficiary designation of the life insurance policy after satisfying his obligation.
See
Tex.R. Civ. P. 166a(e);
Knott,
Conclusion
We hold that the trial court properly granted summary judgment because the movants established that (1) the terms of the decree are unambiguous; (2) no issues of material fact exist; and (3) they are entitled to judgment under the terms of the decree and the life insurance policy.
*621 We therefore affirm the judgment of the trial court.
Notes
. We note that Chapman alternatively contends that we should reverse the judgment of the trial court and render a judgment in her favor if we determine that no genuine issues of material fact exist. Chapman, however, did not move for summary judgment at trial-she merely responded to Abbot, Burks, and Sheehan’s motion for summary judgment. "Before an appellate court may reverse sum-maiy judgment for one party and render judgment for the other party, all parties must have sought final judgment relief in their cross-motions for summary judgment.”
