IN THE SUPREME COURT STATE OF NORTH DAKOTA

2025 ND 40

Brett Michael Kingstone, Plaintiff and Appellant v. Trisa Ranae Tedrow Kingstone, Defendant and Appellee

No. 20240143

Appeal from the District Court of Eddy County, Southeast Judicial District, the Honorable James D. Hovey, Judge.

AFFIRMED IN PART, REVERSED IN PART, AND REMANDED.

Opinion of the Court by Bahr, Justice.

Jacey L. Johnston (argued) and Blayze Fisher (on brief), under the Rule on Limited Practice of Law by Law Students, Grand Forks, ND, for plaintiff and appellant.

Robert G. Will, Minot, ND, for defendant and appellee. Kingstone v. Tedrow Kingstone No. 20240143

Bahr, Justice.

[¶1] Brett Kingstone appeals from a district court judgment awarding child support to Trisa Tedrow Kingstone. On appeal, Brett Kingstone argues the court erred in relying on expert testimony, in calculating his net income for his child support obligation, in awarding an upward deviation of his child support obligation, and in refusing to amend the judgment. We affirm in part, reverse in part, and remand.

I

[¶2] Brett Kingstone and Trisa Tedrow Kingstone were married in Florida in July 2020. They entered a prenuptial agreement before their marriage. The parties have one minor child together, L.R.K., born in 2021. L.R.K. is diagnosed with hemophilia and Fragile X syndrome and has developmental and speech delays.

[¶3] The parties separated in August 2022 when Trisa Tedrow Kingstone and L.R.K. moved from the Colorado marital home to North Dakota. In March 2023, Brett Kingstone commenced a divorce action in Florida and a child custody action in North Dakota. The parties divorced in August 2023 under the binding prenuptial agreement. The Florida divorce action did not address issues related to the minor child.

[¶4] In December 2023, the North Dakota district court held a bench trial. The court awarded Trisa Tedrow Kingstone primary residential responsibility of L.R.K. and child support in the amount of $5,000 per month. Brett Kingstone’s child support obligation includes $3,500, the maximum amount permitted under the child support guidelines when a parent’s monthly income exceeds $25,000, as well as an upward deviation in the amount of $1,500.

[¶5] After the district court entered the judgment, Brett Kingstone moved to clarify or amend the judgment. He asserted the transportation and exchange arrangements provision allowed Trisa Tedrow Kingstone to hinder his ability to

1 exercise his parenting time with L.R.K. because the provision gave Trisa Tedrow Kingstone unilateral control over when to use the “alternative” exchange location. The court denied the motion to amend the judgment. The court granted the motion to clarify the judgment, and clarified that the default exchange location would be at L.R.K.’s home unless the parties mutually agreed to use the alternative exchange location.

II

[¶6] Brett Kingstone argues the district court abused its discretion in relying on Trisa Tedrow Kingstone’s expert witness, Tahnee Magnus. He argues Magnus could not accurately assess his income because she did not review the irrevocable trust agreements.

[¶7] “Expert testimony is admissible whenever specialized knowledge will assist the trier of fact.” Condon v. St. Alexius Med. Ctr., 2019 ND 113, ¶ 28, 926 N.W.2d 136; see also N.D.R.Ev. 702. “Whether a witness is qualified as an expert and whether the testimony will assist the trier of fact are decisions largely within the sound discretion of the trial court.” Condon, ¶ 28. (quoting Kluck v. Kluck, 1997 ND 41, ¶ 7, 561 N.W.2d 263). “A decision to admit expert testimony is reviewed for abuse of discretion only.” Id.

[¶8] Magnus is a certified public accountant and certified fraud examiner with nearly fifteen years of accounting experience. Magnus testified to Brett Kingstone’s income and provided the district court with a summary of her analysis. At trial, Magnus testified her summary was “based strictly off his personal return and the holding company returns” from 2017 to 2022, as required by child support guidelines. See N.D. Admin. Code § 75-02-04.1-02(7) (“Income must be sufficiently documented through the use of tax returns, current wage statements, and other information to fully apprise the court of all gross income.”). She also testified she lacked access to the irrevocable trust agreements, but that she believes her summary accurately reflects Brett Kingstone’s income.

[¶9] Magnus’s lack of access to the irrevocable trust documents goes toward the weight of her testimony, not its admissibility. In re J.M., 2013 ND 11, ¶ 14,

2 826 N.W.2d 315 (doctor’s admitted failure to review patient’s entire file “goes to the weight of her opinion and not to its admissibility”); Victory Park Apartments, Inc. v. Axelson, 367 N.W.2d 155, 163 (N.D. 1985) (stating “the weakness or non- existence of a basis for an expert’s opinion goes to his credibility, and not necessarily to the admissibility of the opinion evidence”). We conclude the district court did not abuse its discretion in relying on Trisa Tedrow Kingstone’s expert witness in determining Brett Kingstone’s income for his child support obligation.

III

[¶10] The standard of review for child support decisions is well-established:

Child support determinations involve questions of law which are subject to the de novo standard of review, findings of fact which are subject to the clearly erroneous standard of review, and may, in some limited areas, be matters of discretion subject to the abuse of discretion standard of review. A finding of fact is clearly erroneous if it is induced by an erroneous view of the law, if no evidence exists to support it, or if, on the entire record, we are left with a definite and firm conviction that a mistake has been made.

Williams v. Williams, 2023 ND 240, ¶ 14, 999 N.W.2d 192 (quoting Updike v. Updike, 2022 ND 99, ¶ 5, 974 N.W.2d 360). “A court errs as a matter of law if it does not comply with the requirements of the child support guidelines.” Knudson v. Knudson, 2018 ND 199, ¶ 24, 916 N.W.2d 793. “The amount of child support calculated under the guidelines is rebuttably presumed to be the correct amount of child support in all child support determinations.” Williams, ¶ 14 (quoting Thompson v. Johnson, 2018 ND 142, ¶ 9, 912 N.W.2d 315); see also N.D.C.C. § 14- 09-09.7(4).

[¶11] “A correct finding of an obligor’s net income is essential to determining the proper amount of child support.” Knudson, 2018 ND 199, ¶ 25 (quoting Thompson, 2018 ND 142, ¶ 9). “Income must be sufficiently documented through the use of tax returns, current wage statements, and other information to fully apprise the court of all gross income.” N.D. Admin. Code § 75-02-04.1-02(7). After determining the obligor’s net income, the district court must apply the net

3 income to the child support guidelines to calculate the proper amount of child support. Knudson, ¶ 26. Section 75-02-04.1-02(11), N.D. Admin. Code, explains certain sources of the obligor’s income are deducted from the obligor’s gross annual income to calculate net income. Section 75-02-04.1-01(4), N.D. Admin. Code, defines gross income to mean “income from any source, in any form,” except for limited exclusions. “The definition of ‘gross income’ is ‘very broad and is intended to include any form of payment to an obligor, regardless of source, which is not specifically excluded under the guidelines.’” Knudson, ¶ 26 (quoting Wilson v. Wilson, 2014 ND 199, ¶ 24, 855 N.W.2d 105).

[¶12] Brett Kingstone argues the district court improperly considered irrevocable trust income reported on his personal tax returns when calculating his gross income.
