COURT OF APPEALS

COURTNEY LYNN TROOST, also known as UNPUBLISHED COURTNEY LYNN HORNBECK, September 11, 2025 1:37 PM Plaintiff-Appellant,

v No. 372188 Montcalm Circuit Court SEAN MICHAEL-ALLEN TROOST, LC No. 2019-025447-DM

Defendant-Appellee.

Before: FEENEY, P.J., and BORRELLO and LETICA, JJ.

PER CURIAM.

Plaintiff, Courtney Lynn Troost, also known as Courtney Lynn Hornbeck, appeals as of right the trial court’s order granting a motion by defendant, Sean Michael-Allen Troost, to change custody of the parties’ minor children, JT and FT. We affirm.

I. FACTS

Plaintiff and defendant married in December 2012, and they had two children during the marriage, JT and FT. Plaintiff filed a complaint for divorce in June 2019. In March 2020, the trial court entered a judgment of divorce, which provided that: the parties would share joint legal custody of the children, the children would reside with plaintiff, and defendant would have liberal parenting time as agreed by the parties. In 2021, the trial court entered an order granting defendant parenting time as set forth in the Montcalm County Friend of the Court (FOC) parenting-time policy and as the parties agreed.

Plaintiff married Shane Hornbeck in November 2022, and the couple had a child together in 2023. In June 2023, plaintiff filed an ex parte motion to suspend defendant’s parenting time and asserted that defendant emotionally and verbally abused the children by convincing them to lie and say that Shane was physically abusive. But in July 2023, during the referee’s hearing on plaintiff’s motion, evidence disclosed that Children’s Protective Services (CPS) substantiated a report that both plaintiff and Shane physically abused FT. Accordingly, defendant asked for an expedited court hearing on the basis that the children were not safe in plaintiff’s home. The referee stated that the only issue before it was plaintiff’s motion to suspend defendant’s parenting time,

-1- and plaintiff failed to show proper cause or change in circumstances to modify defendant’s parenting time; however, the referee noted that defendant could file an ex parte motion if he wanted to address his concerns with the trial court. The very next day, defendant moved for sole legal and physical custody, and in an ex parte order, the trial court: (1) granted defendant’s motion in part, (2) ordered that Shane could not have contact with the children, and (3) ordered the FOC to conduct a full custody investigation. Plaintiff subsequently filed an objection.

In August 2023, the FOC completed its report. Thereafter, the referee conducted an evidentiary hearing to address custody, parenting time, child support, and plaintiff’s objection to the ex parte order. The referee found that the children did not have an established custodial environment with either parent and that defendant proved by a preponderance of evidence that a change in custody was in the children’s best interests. In November 2023, the trial court signed the referee’s recommended order, which provided that the parties would share joint legal custody of the children, defendant would have primary physical custody, and plaintiff would have parenting time in accordance with the circuit court’s FOC parenting-time policy. The order also stated that Shane could not have contact with the children.

Plaintiff filed a timely objection, asking the trial court to conduct a de novo review. Plaintiff noticed the hearing for January 2024, but then adjourned the hearing to February 2024. Plaintiff moved to supplement the record to add witnesses at the de novo hearing, which the trial court partially granted. In June 2024, the trial court began the de novo hearing. In July 2024, the parties made their closing arguments, and the trial court gave its opinion from the bench, finding that: (1) the referee correctly found proper cause or change in circumstances to reconsider the previous custody order, and (2) granting defendant physical custody was in the children’s best interests. The trial court then issued its written order, stating that the order of November 2023 would remain in effect. Plaintiff now appeals.

II. PRESERVATION AND STANDARD OF REVIEW

Generally, a party preserves an issue for appeal by raising it in the trial court. Kuebler v Kuebler, 346 Mich App 633, 652 n 9; 13 NW3d 339 (2023). In this case, plaintiff preserved her content-based objections to the ex parte order and the order following the referee’s custody hearing by filing her objections in the trial court. See id. But plaintiff never objected to, or raised any argument about, the timing of the trial court’s review of her objections; therefore, her untimeliness- claims are not preserved for appellate review. See id.

As set forth in the Child Custody Act, MCL 722.21 et seq., we must affirm a child custody order on appeal unless the trial court’s factual findings, including those regarding the existence of an established custodial environment and the best-interest factors, were against the great weight of the evidence; the trial court committed a palpable abuse of discretion; or the trial court made a clear legal error on a major issue. See MCL 722.28; Fletcher v Fletcher, 447 Mich 871, 876-877; 526 NW2d 889 (1994); Safdar v Aziz, 342 Mich App 165, 175-176; 992 NW2d 913 (2022); Pennington v Pennington, 329 Mich App 562, 570; 944 NW2d 131 (2019). Additionally, “[w]e defer to the special ability of the trial court to judge the credibility of witnesses.” Cassidy v Cassidy, 318 Mich App 463, 476; 899 NW2d 65 (2017) (quotation marks and citation omitted).

-2- As our Supreme Court explained in Sabatine v Sabatine, 513 Mich 276, 284; 15 NW3d 204 (2024):

MCL 722.28 incorporates three standards of review into the act: (1) “a reviewing court should not substitute its judgment on questions of fact unless the factual determination clearly preponderates in the opposite direction,” Pierron v Pierron, 486 Mich 81, 85; 782 NW2d 480 (2010) (cleaned up); (2) “an abuse of discretion occurs if the result is so palpably and grossly violative of fact and logic that it evidences not the exercise of will but perversity of will, not the exercise of judgment but defiance thereof, not the exercise of reason but rather of passion or bias,” Maier v Maier, 311 Mich App 218, 221, 874 NW2d 725 (2015) (cleaned up); and (3) clear legal error exists when “a court incorrectly chooses, interprets, or applies the law,” Fletcher[, 447 Mich at 881].

Plaintiff also argues that the trial court violated the court rules, which is a claim that we review de novo. See McGregor v Jones, 346 Mich App 97, 100; 11 NW3d 597 (2023).

Unpreserved claims in a child custody proceeding are reviewed for plain error. Quint v Quint, ___ Mich App ___, ___; ___ NW3d ___ (2024) (Docket No. 368002); slip op at 7.

To show that a plain error occurred warranting reversal, the following four elements must be established on appeal:

1) error must have occurred, 2) the error was plain, i.e., clear or obvious, 3) the plain error affected substantial rights, and 4) once a defendant satisfies these three requirements, an appellate court must exercise its discretion in deciding whether to reverse. Reversal is warranted when the plain, forfeited error seriously affected the fairness, integrity or public reputation of judicial proceedings. [Id. (quotation marks and citation omitted).]
