We affirm in part, reverse in part, and remand.
Appellant raises the following issues on appeal:
1. Did the District Court err in declaring the judgment from the dissolution of the parties’ first marriage “null and void” where thе judgment required periodic installment payments from respondent to appellant for her interest in the ranch assets acquired during the parties’ first marriage?
2. Did the trial court err in failing to compensate appellant for her interest in the parties’ ranching operation developed during their second marriage?
*354 Respondent’s issue on cross-appeal is:
Did the District Court err in its valuation and distribution of the marital estate?
Patricia Halse Nordberg (now known as Patricia Halse) and Dean Nordberg were first married on May 5, 1981, in Sheridan, Montana. Prior to the time the parties married, Patricia was a homemaker and Dean was an ironworker. He later worked in cattle operations. No children were born of this marriage, although both parties have adult children from othеr marriages. Patricia was formerly widowed and brought the following assets to the first marriage: a family business, a homestead with a house and 19 acres, bonds from inheritance, life insurance proceeds, and various properties. Dean’s assets consisted of gold coins and personal property, and part ownership of a home. During this marriage the parties accumulated real property and livestock, farm and ranching equipment, and machinery. At the time of the present dispute, Patricia was 59 years of age and worked part-time at a sewing shop, and Dean was 58 years of age and operated his ranching business.
On April 21, 1987, with each party represented by their own attorney, the marriage was dissolved and the parties’ submitted property settlement agreement was incorporated into the final decree. The settlement granted the couple all property individually acquired before the marriage. Patricia received the two rental properties acquired during the marriage. Dean was granted the livestock, valued at $75,320, and ranch vehicles, equipment, tools, and machinery, valued at $39,800. As part of the property settlement of the cattle and machinery, Dean agreed to pay to Patricia $80,000 as full settlement of her claim to the property. Pursuant to the terms of the agreement, Dean paid $30,000 upon execution of the agreement. Dean was to pay the remaining $50,000 in the following manner: the first installment of $25,000 wаs due one year from the agreement date, and the second installment of $20,000 was due two years from the agreement date; Dean was to execute two promissory notes for $10,000, with one note having a security interest in Dean’s cattle, and the other secured by a title lien interest in his two pickups; and an additional $5,000 certificate of deposit was due two yeаrs from the agreement date. Dean never executed the documents nor did he pay the installment payments.
The parties were remarried approximately seven months later on September 30, 1987. This subsequent marriage was dissolved on June 29, 1993. During this second marriage the couple obtained *355 rental property and purchased more cattle. Patricia contributed her separately-owned real property for running the ranching operation and infrequently participated in the operation during this marriage. Dean maintained and managed the ranching operation.
On April 13,1992, Patricia filed for dissolution of her marriage to Dean. The parties’ relationship during the dissolution proceedings was hostile and both disputed the distribution of the assets. On April 21, 1992, prior to the entry of the final decree, Dean sold 52 cow/calf pairs. In June 1992, the court ordered the proceeds of the sale divided equally between the parties and granted $58,940 to each.
After the matter was heard before a Special Master on December 28-29, 1992, the Special Master issued findings of fact and conclusions of law. Both parties filed objections to these findings which were denied. On June 29,1993, the District Court issued a judgment confirming the Special Master’s findings, denying the parties’ objections, and declaring the February 3, 1987, judgment from the prior dissolution decree “null and void.” Patricia appeals the District Court’s findings distributing the property and voiding the prior dissolution judgment, and Dean cross-appeаls the division of the marital estate.
ISSUE 1
Did the District Court err in declaring the judgment from the dissolution of the parties’ first marriage “null and void” where the judgment required periodic installment payments from respondent to appellant for her interest in the ranch assets acquired during the parties’ first marriage?
The first dissolution settlement agreement between the parties granted Dean thе livestock and ranch vehicles, equipment, tools, and machinery. As part of the property settlement of the cattle and machinery, Dean agreed to pay to Patricia $80,000 as full settlement of her claim to the property. Dean paid $30,000 upon execution of the agreement. The remaining installments were never paid. Dean argues that the judgment from the prior dissolution settlement for the ranching operation was satisfied by his payments for property taxes on Patricia’s separate properties, by his payments for the parties’ income taxes, and also, by his contribution of physical labor to improve her separate property.
Unlike the first dissolution where the parties entered into a sеttlement agreement, they agreed that a Special Master would assist in the proceedings for division of the marital estate for the second *356 dissolution. The District Court adopted the Special Master’s findings. In Finding of Fact No. 7, the court states:
Neither party has performed or complied with the terms of the prior Property Settlement Agreement and Decree. The Court finds that both parties are estopped from asserting any rights under the previous decree and agreement. Both parties should be discharged from any obligation under that judgment.
In the judgment, the court further stated that “[t]he previous decree in Madison County Cause No. 7449 entered between these parties is declared null and void.”
Prior to the time a property sеttlement is approved and merged into a decree, § 40-4-201, MCA, allows the court to determine whether the agreement is unconscionable. In
Hadford v. Hadford
(1981),
Under section 40-4-201(2), MCA, the courts are bound by a property settlement agreement signed by both parties unless the court then finds the agreement to be unconscionable. Under this statute, the court can determine the question of conscionability on its own motion, or either of the parties can raise this issue before the agreement is merged into a decree and becomes final. [Emphasis added].
After the trial court determines that the property settlement is not unconscionable, § 40-4-201, MCA, provides in part:
(4)(a) unless the separation agreement provides to the contrary, its terms shall be set forth in the decree of dissolution ... and the parties shall be ordered to perform them; or
(5) Terms of the agreement set forth in the decree are enforceable by all remedies available for enforcement of a judgment, including contempt, and are enforceable as contract terms.
In the present case, the trial court found the parties’ sеttlement agreement was not unconscionable and the settlement was merged into the dissolution decree. The judgment became final when no appeal was taken by either party before the appeal time expired under Rule 5, M.R.App.P
In order to modify or revoke a final property disposition, § 40-4-208, MCA, requires in pertinent part:
(3) The provisions as to property disposition may not be revoked or modified by a court, except:
(a) upon written consent of the parties; or
*357 (b) if the court finds the existence of conditions that justify the reopening of a judgment under the laws of this state. [Emphasis added].
Rule 60(b), M.R.Civ.P., upon motion by a рarty or a party’s legal representative, for several enumerated reasons, allows relief from a final order, judgment, or proceeding. Since neither party filed a motion for relief in this matter, we consider the residual clause of Rule 60(b) which allows the filing of an independent action based on equitable grounds, stating in pertinent part:
This rule does not limit the рower of a court to entertain an independent action to relieve a party from a judgment, order, or proceeding, or to grant relief to a defendant not actually personally notified as may be required by law, or to set aside a judgment for fraud upon the court.
Those parties requesting relief under the 60(b) residual clause may base their claim uрon extrinsic fraud, lack of personal notification, and fraud upon the court.
Brown v. Small
(1992),
The District Court did not have jurisdiction to vacate the prior judgment. We need not discuss whether the court was justified to vacate the judgment bаsed upon equitable estoppel. We hold that the District Court erred in declaring the judgment from the dissolution of the parties’ first marriage “null and void.”
ISSUE 2
Did the trial court err in failing to compensate appellant for her interest in the parties’ ranching operation developed during their second marriage?
Patricia argues that she was not compensated fоr her contribution to the ranching operation and that Dean received more than a majority of the marital assets resulting in an inequitable distribution. She asserts that she contributed the greater portion to the parties’ *358 assets by her large financial contributions during the first marriage when she spent $90,919 of her separate funds to establish the ranching operation. She also argues that she made the following additional contributions during the second marriage without receiving her interest from the ranching operation: the contribution of $19,375 of her own separate funds to purchase additional cattle; the contribution of her separate real property for cattle grazing; and the financial contribution for all the parties’ personal living expenses and most of the property taxes and insurance.
Dean argues that because the judgment from the prior dissolution settlement for the ranching operation was satisfied as argued in the first issue, she received all her interest in the ranching operation from the first marriage. He also maintains that she made minimal contributions to the ranching oрeration during the second marriage and he made the greater contribution. He contends that although the District Court granted him the ranching operation, it fashioned an equitable distribution by adjusting all the marital assets between the parties, awarding her an interest in all the marital property, including the ranching operation, when it granted Patricia the rental properties and ring.
Distribution of the marital estate is determined by the guidelines in § 40-4-202(1), MCA, which provides in part:
In a proceeding for dissolution of a marriage ... the court, without regard to marital misconduct, shall... finally equitably apportion between the parties the property and assets belonging to either or both, however and whenever acquired and whether the title thereto is in the name of the husband or wife or both.
This statute grants the district court broad discretion to apportion the marital estate equitably to each party under the circumstances.
In re Marriage of Zander
(1993),
Our review of marital property divisions is whether the district court’s findings of fact are clearly erroneous.
In re Marriage of Maedje
(1994),
The court upheld the $59,940 distribution to Dean for the one-half interest in the interim sale of cattle, and granted him the ranching operation valued at $130,075 and debts associated with the operation totaling $35,624.24, along with the $5,500 debt associated with the diamond ring awarded to Patricia, giving a net total of $148,890.76. He also received miscellaneous persоnal property.
The record shows that the District Court properly considered the statutory requirements within § 40-4-202, MCA. The Special Master, in the memorandum in support of findings, stated:
The Court recognizes that the division of the marital estate is not equal in this matter. Respondent has received a slight majority of the marital estate. This finding is justified by the equities in this action when considering PATRICIAS extensive separate properties and DEAN’S relative lack thereof. It is in the Court’s discretion to divide the property in this matter.
Before distributing the marital property the court determined the value of the marital properties and debts, and found that the parties contributed to the marital assets either in the form of money or labor and management decisions. The сourt determined the contributions to be of equal value. The court also properly considered the source of the parties’ assets. In her argument that she should receive an interest in the ranching operation because she invested her separate assets in the operation, Patricia attempts to lump together all the monetary contributions she made during the parties’ first marriage and second marriage. As discussed above in the first issue, the marital assets in the first marriage were settled by the parties’ agreement. In the second dissolution, the District Court properly determined that the marital assets acquired only during the second marriage were to be considered marital assets.
Patricia argues that

(1987),
ISSUE 3
Did the District Court err in its valuation and distribution of the marital estate?
Dean argues that the District Court erred by not computing the net worth of the parties before distributing thе marital property pursuant to § 40-4-202, MCA.
After the Special Master issued the findings concerning the division of assets, Dean did not object to the absence of net worth, but only objected to personal property he did not receive. This Court will not find error in a district court’s ruling or procedure where the appellant acquiesced, participated, or did not оbject.

(1990),

Dean also argues that Patricia’s property was undervalued and much of her property was imprоperly omitted from the marital estate. After the time for discovery was over, the Special Master denied Dean’s motion for production of documents, stating that the motion was untimely, and that the parties had been granted ample time for discovery and raising the new issues at the close of evidence would necessitate an unwarranted continuancе of the hearing. Further, the court addressed the substance of the motion stating that the evidence was clear and convincing that Halse Enterprises was Patricia’s separate asset and that Dean did not facilitate the maintenance of the asset. Those assets belonging to a spouse prior to a marriage, or acquired by gift, bequest, devise, or desсent during the marriage are not part of the marital estate unless the spouse made contributions in the preservation or interest in that property.
In re Marriage of Smith
(Mont. 1994),
We affirm the District Court’s valuation and distribution of the marital assets. We reverse and remand to the District Court to reinstate the prior judgment and for further proceedings to determine the balance owed to Patricia from the judgment.
