__________________________________________ Clerk Justice Ingrid Gustafson delivered the Opinion of the Court.

¶1 Taralyn DeCock (Taralyn) appeals from the August 25, 2025 deemed denial of her

M. R. Civ. P. 60(b)(6) motion for relief from the Findings of Fact, Conclusions of Law,

and Final Decree of Dissolution ordered by the Fifth Judicial District Court, Beaverhead

County, on February 25, 2025. Taralyn asserts the District Court’s deemed denial of her

Rule 60 motion was an abuse of discretion and that she is entitled to relief on account of

the gross neglect of her prior counsel. Specifically, Taralyn argues that counsel failed to

provide her with information regarding her spouse’s retirement assets prior to mediation,

which resulted in a distribution of assets that “shocks the conscience.” Additionally,

Taralyn argues the District Court’s October 31, 2024 order denying her motion to rescind

the Marital and Property Distribution Agreement (MPSA) constitutes reversible error, as

the agreement was unconscionable. Further, Taralyn asserts the District Court failed to

fulfill its statutory duty to ensure an equitable distribution of assets when it adopted the

MPSA into its final decree of dissolution. Taralyn, however, filed her Notice of Appeal on

August 29, 2025, 185 days after the District Court issued its final decree of dissolution.

While her appeal is timely as to the denial of her Rule 60 motion, her appeal of the District

Court’s final decree of dissolution is not.1 Accordingly, we restate the sole issue on appeal

as follows:

1 Under M. R. App. P. Rule 4(5)(a)(i), notice of appeal in civil cases “shall be filed with the clerk of the supreme court within 30 days from the date of entry of the judgment or order from which the appeal is taken.” Accordingly, Taralyn’s appeal of the District Court’s final decree, which she bases on allegations that the District Court erroneously denied her motion to rescind the MPSA and failed to ensure an equitable distribution of assets under § 40-4-202, MCA, is untimely. 2 Whether the District Court abused its discretion when it denied Taralyn’s Rule 60(b)(6) motion.

FACTUAL AND PROCEDURAL BACKGROUND

¶2 This case arises from the dissolution of a fifteen-year marriage between Taralyn and

Dean DeCock (Dean). The parties were married in Bozeman, Montana, on June 27, 2009.

Around October 1, 2023, Taralyn moved out of the couple’s marital home in Dillon,

Montana, along with their two minor children. On November 13, 2023, Taralyn filed a

petition for dissolution of marriage.

¶3 On February 15, 2024, Taralyn—through counsel—was served Dean’s initial

financial disclosures, which provided an accounting of Dean’s assets and liabilities. Under

“Retirement Benefits,” the disclosure specifically referenced the following assets: Social

Security, valued at $333,536.00; Newmont (Newmont Pension), valued at $127,825.43;

Fidelity (Covia Retirement), valued at $152,615.19; John Hancock (MTI Savings Plan),

valued at $81,350.42; Edward Jones (Roth IRA), valued at $139,872.39; and Edward Jones

(IRA Advisory Solutions Fund), valued at $278,964.59.

¶4 On March 5, 2024, Taralyn and Dean, along with their respective counsels,

participated in mediation. According to Dean, prior to meeting, counsel for Taralyn

requested that hard copies of Dean’s financial disclosures be distributed at mediation,

including account statements pertaining to Dean’s retirement assets. The parties met from

However, Taralyn’s appeal of the District Court’s August, 25, 2025 deemed denial of her Rule 60(b)(6) motion is timely, as her Notice of Appeal was filed only 4 days later. 3 10:00 a.m. to 3:12 p.m. and copies of both the disclosures and statements were provided.2

The mediator, Pat Gallagher, also had copies of the financial disclosures for both parties.

Though the parties were unable to resolve certain issues related to the parenting plan, the

parties did reach an agreement as to all marital and property settlement issues. An

agreement—the MPSA—entitled “Marital and Property Distribution Agreement” was

executed and signed by both Taralyn and Dean and filed with the District Court that day.

¶5 In the recitals, the MPSA provides the following:

D. The parties wish to effectuate an amicable settlement of the disposition of real and personal property and the payment and/or assumption of debts.

E. When the Decree of Dissolution is entered, it is the intention of the parties that this Agreement be determined by the [c]ourt to be fair and equitable, and it is specifically intended by the parties hereto that this Agreement be incorporated into the Decree of Dissolution of marriage that will be entered in the Fifth Judicial District Court, Beaverhead County.

F. The parties have made initial disclosures and explicitly waive final financial disclosures.

G. This Agreement is voluntary. Each of the parties have read and approved this Agreement.

The MPSA then proceeds to outline the disposition of marital assets, including the

disposition of vehicles and recreational property, real estate, business, bank accounts,

personal property, and retirement accounts. Regarding retirement accounts, the MPSA

specifically provides:

2 Taralyn does not dispute that financial disclosures and account statements were available for review at mediation. 4 5. Retirement Accounts/Life Insurance: a. Each party shall retain the retirement accounts and Social Security in their own name unless specified as follows; a. Dean shall retain the following: 1. Newmont Pension 2. Newmont Company Stocks 3. Newmont Investment Stocks 4. Covia Retirement (Fidelity) 5. MTI Savings Plan 401K JH 6. Roth IRA (Edward Jones) 7. IRA Advisory Solutions Fund (Edward Jones) 8. Community Property WROS Select (Edward Jones) b. Taralyn shall receive the following, and the parties shall effectuate exchange of personal items through counsel within 30 days of execution of this agreement; 1. NV TOD 2. CB&T IRA 3. CB&T Roth 4. $139,000 from Dean’s Edward Jones Roth IRA. Dean shall transfer $139,000 of the balance of his Edward Jones Roth IRA to Taralyn via a Qualified Domestic Relations Order. Taralyn shall designate the qualified account into which she requests the funds be transferred. If Taralyn is unable to obtain the full amount of this cash due to any “penalty” or taxes, Dean shall pay in cash the difference. This is specifically done to evenly distribute the retirement funds, but allow them both to have the most available cash, rather than Taralyn retrieving less in retirement funds, or Dean from having less equity in the home. 5. Taralyn shall receive $15,000 from a retirement account of Dean’s designation via a Qualified Domestic Relations Order. . . .

With regard to all marital assets, the MPSA further provides:
