Montana Rule: A Buy-Sell + Seller-Financing Amendment Is Enforceable Despite Later “Mutually Agreed” Contract-for-Deed Terms; Added Public-Access Encumbrances Breach Condition-of-Title

I. Introduction

Melby v. Doering (Mont. 2026 MT 119) arises from a failed sale of “Marshall Mountain,” a 156-acre property in Missoula County. Plaintiffs Spencer and Collette Melby (buyers) and defendants Bruce and Kim Doering (sellers) executed a written Buy-Sell Agreement, later amended to replace conventional financing with a seller-financed contract for deed. When the parties began negotiating the final contract-for-deed document, the sellers inserted extensive additional terms—most notably a sweeping “Public Access” easement concept—and then terminated the transaction when the buyers refused the change.

The central appellate issue was contract-formation: whether the Amendment’s statement that the “Final contract for deed [is] to be mutually agreed upon by both parties” meant there was no enforceable contract at all until the final contract-for-deed document was agreed upon and signed. The Montana Supreme Court held the opposite: the Buy-Sell Agreement and Amendment together formed an enforceable contract; the “mutually agreed” language, at most, concerned performance (closing), not formation.

II. Summary of the Opinion

The Court affirmed partial summary judgment for the Melbys on breach of contract. It held:

  • The executed Buy-Sell Agreement—expressly labeled a “legally binding contract”—and the seller-financing Amendment contained all essential elements and material terms for a land sale.
  • The clause “Final contract for deed to be mutually agreed upon by both parties” did not clearly and unambiguously create a condition precedent to contract formation.
  • Additional terms the sellers later demanded (default provisions, guaranty, indemnity, possession/access details, etc.) were generally “subsidiary” or performance-related, not material terms required for formation.
  • The sellers’ proposed “Public Access” provision was atypical, contradicted the Title Contingency/Commitment/Condition of Title, and materially altered what was being sold; inserting it and terminating over it constituted breach.

The Court remanded for further proceedings (damages and other claims), leaving intact the District Court’s ruling that factual disputes remained on the implied covenant claim.

III. Analysis

A. Precedents Cited (and How They Shaped the Decision)

1. Contract interpretation and reading documents together

  • Schwend v. Schwend (cited in GRB Farm v. Christman Ranch, Inc.): Reinforced the baseline rule that clear, unambiguous contracts are enforced as written. This undergirded the Court’s textual approach to the Buy-Sell’s “legally binding contract” language and “Entire Agreement” clause.
  • Lewis & Clark Cnty. v. Wirth and statutes §§ 28-3-202 and 28-3-203, MCA: Supported reading the Buy-Sell and Amendment together as parts of a single transaction, harmonizing general intent with specific clauses. This framework let the Court treat the Amendment as a financing modification, not a wholesale re-negotiation of contract existence.
  • Mary J. Baker Rev. Tr. v. Cenex Harvest States, Coop. Inc.: Emphasized discerning mutual intent from the writing at the time of contracting, limiting post hoc characterizations that the parties “didn’t really mean to be bound” until later paperwork.

2. Formation vs. “agreement to agree” and the enforceability of preliminary writings

  • Hurly v. Lake Cabin Dev., LLC: Provided the three-part enforceability framework for informal vs. contemplated later formal contracts: (1) essential elements; (2) all agreed material terms; (3) no clear requirement that a later formal agreement is a condition precedent to formation. The Court applied this structure directly, treating the Buy-Sell/Amendment as the binding core and the later contract-for-deed drafting as implementation detail.
  • Kluver v. PPL Mont., LLC: Supplied the principle that “tentative” labels or ongoing drafting do not defeat enforceability where the writing shows intent to be bound. Kluver’s assent-focused analysis (“manifested assent” and “has not manifested an intent not to be bound”) helped the Court reject the sellers’ reliance on continued negotiations.
  • Steen v. Rustad: Anchored Montana’s long-standing rule: a binding agreement is not rendered unenforceable merely because the parties plan to later memorialize it more formally, so long as there is “reasonable certainty and completeness” on critical issues. The Court relied on Steen to classify many later-proposed terms as nonessential to formation.
  • GRB Farm v. Christman Ranch, Inc.: Distinguished enforceable preliminary agreements from unenforceable “agreements to agree,” reinforcing that only future agreement on material terms threatens enforceability.

3. Conditions precedent: formation vs. performance

  • Hanson v. Town of Fort Peck: The Court used Hanson to show that where a condition precedent to formation exists, the record typically contains a clear, agreed condition (there, town council approval). Here, by contrast, the Buy-Sell’s structure (enumerated contingencies with notice/waiver mechanics) suggested the parties knew how to draft explicit conditions and did not do so for “final contract for deed” agreement.
  • Davidson v. Barstad, Thompson v. Lithia Chrysler Jeep Dodge of Great Falls, Inc., and Bender v. Rosman: These cases supplied the doctrinal split: a condition precedent can govern formation (no contract until event occurs) or performance (contract exists, but duty to perform is contingent). This distinction was dispositive: the “mutually agreed” clause was read, “at most,” as a condition to closing/performance, not to contract formation.
  • Patton v. Madison County: Served as the counterexample where the parties used clear, definite language conditioning settlement on later document approval. The Court contrasted Patton’s explicit conditional phrasing with the Buy-Sell’s explicit “legally binding contract” language and the absence of a new contingency term.
  • Olsen v. Johnston (also cited in the “manifest, clear, and definite” condition-to-formation discussion): Used to show courts do not find formation conditions unless the language clearly excludes other interpretations.

4. Land-sale material terms and contract-for-deed disputes

  • Perl v. Grant and Olsen v. Johnston: Provided the modern list of land-sale “material terms” (parties, subject matter, property description, price/price criteria, mutual assent). The Court agreed the Buy-Sell/Amendment met these requirements and then emphasized Olsen’s corollary: performance/collateral matters are not material terms unless the parties make them so.
  • Dineen v. Sullivan: Invoked by the sellers to argue a writing must contain all “stipulations and undertakings.” The Court distinguished Dineen as a statute-of-frauds problem involving alleged oral terms omitted from the writing; here, the sellers did not claim pre-existing oral material terms were left out.
  • Maxted v. Stenberg: The closest analog—seller refused to convey after a buy-sell was executed but before final contract-for-deed terms were reduced to writing. Maxted supported enforceability: absence of later performance-detail terms did not defeat the buy-sell; similarly, Doerings’ added “protective” provisions did not retroactively become material terms.
  • Smith v. Johnson: Reinforced that attempts to negotiate additional contract-for-deed terms do not negate the underlying buy/sell agreement or the ability to sue on it.
  • Zier v. Lewis: Supplied the “same thing in the same sense” mutuality formulation, which the Court satisfied by pointing to the executed Buy-Sell/Amendment terms and the approved title commitment.

B. Legal Reasoning

1. The Amendment did not undo the Buy-Sell’s binding character

The Court treated the Amendment as exactly what it said it was: an “Amendment to Agreement between Parties for Existing Terms and Conditions” that modified only the “Purchase Price and Terms” to adopt seller financing, while incorporating the rest of the Buy-Sell unchanged. The Buy-Sell’s opening admonition—“This is a legally binding contract”— and the “Entire Agreement” clause were key textual anchors.

2. “Final contract for deed to be mutually agreed” was not a formation condition

The Court refused to read one sentence as silently transforming a signed land-sale contract into a nonbinding “agreement to agree,” especially when:

  • The Buy-Sell contained multiple expressly drafted contingencies (inspection, appraisal, insurance, lead-based paint, financing, title), with specific notice/waiver procedures.
  • The parties had blank “This Agreement is contingent upon...” placeholders they did not use to add a new formation contingency about executing a final contract for deed.
  • Montana law disfavors conditions unless “unambiguous language” indicates a conditional obligation.

Read in context, the clause was treated as addressing the mechanics of closing under seller financing (performance), not the existence of the deal (formation).

3. Material terms were present; later-drafted “protections” were performance details

The Court applied Perl/Olsen’s material-terms list and held the Buy-Sell/Amendment supplied them, including seller-financing specifics (down payment, interest rate, amortization, balloon, escrow allocation). Proposed additions like guaranty, default/remedies, indemnity, maintenance, escrow timing, and possession/access were categorized as collateral/performance-related—similar to Maxted’s rejection of arguments that missing details about taxes, interest, security, or time of performance defeated formation.

4. The “Public Access” provision was legally and contractually disruptive

Although the Court’s holding did not require deciding every draft-term dispute, it highlighted the Public Access provision as a pivotal fact for two reasons:

  • Conflict with title terms: The Title Contingency, the approved preliminary title commitment (listing only three discrete easements), and the “Condition of Title” clause barred sellers from placing “additional encumbrances, restrictions, easements or other adverse title conditions” after the commitment’s effective date. A broad public-access easement over “any part of the 156 acres” directly contradicted these bargained-for title protections.
  • Mismatch with the seller-financing justification: The sellers argued seller financing inherently required more terms. But the negotiation breakdown arose from a new public-encumbrance demand, unrelated to financing risk allocation, and described as atypical even by counsel. This undermined the narrative that the parties merely hadn’t finished financing terms.

5. Procedural note: attorney-client privilege dispute mooted

The Court denied as moot the sellers’ motion to strike materials allegedly reflecting privileged communications, stating its analysis did not rely on such communications. Practically, this signals the holding rests on contract text and non-privileged record facts, reducing vulnerability to evidentiary skirmishes.

C. Impact

1. Drafting lesson: “mutually agreed” language will not lightly negate a signed land contract

The decision strengthens Montana’s enforceability baseline for signed buy-sell agreements and amendments: if parties want a later document (e.g., final contract for deed) to be a condition to formation, they must say so with clarity comparable to Patton’s conditional settlement language, or by adding a specific contingency in the agreement’s contingency framework.

2. Seller-financing amendments: include core financing economics; do not rely on later forms to supply formation essentials

The Court treated the inclusion of down payment, interest, amortization term, balloon date, and fee allocation as “crucial” to the seller-financing relationship. Future litigants will likely argue enforceability turns on whether such core economic terms were fixed in the amendment, even if other provisions remain to be drafted.

3. Title protections have teeth even during “financing document” negotiations

By tying the Public Access term to the Title Contingency/Commitment/Condition of Title, the Court indicates sellers cannot use later contract-for-deed drafting to introduce new easements or encumbrances inconsistent with the agreed title package. This gives buyers a strong textual hook to treat such late additions as breach, not mere negotiation.

4. Litigation posture: summary judgment is viable where the writings are complete on material terms

The Court’s willingness to affirm partial summary judgment suggests that, when the contract documents are clear and the missing terms are plausibly “subsidiary,” Montana courts may resolve enforceability and breach as a matter of law, leaving only damages and ancillary claims for trial.

IV. Complex Concepts Simplified

  • Contract for deed: A seller-financing device where the buyer makes payments over time and the seller typically retains legal title until payoff. It often requires detailed default/remedy terms, but those details are not automatically “material” to whether the parties formed a binding sale contract.
  • Condition precedent to formation vs. performance: A formation condition means “no contract exists unless X happens.” A performance condition means “the contract exists, but a party’s duty to perform is not triggered unless X happens.” The Court read “final contract for deed to be mutually agreed” as, at most, the second type.
  • Agreement to agree: A nonbinding arrangement where parties leave essential terms to future negotiation. Montana distinguishes this from a binding agreement that leaves only collateral/performance details for later documentation.
  • Material terms (land sale): Generally the identity of parties, the property, a reasonably certain description, price (or method), and mutual assent. Other items are usually “subsidiary” unless the parties expressly make them conditions of the deal.
  • Title commitment / exceptions: The preliminary insurer/lender title report listing what burdens (easements, liens, restrictions) will be excepted from coverage. Here it effectively defined the agreed encumbrance set; adding a new public-access easement later conflicted with the contract’s title promises.

V. Conclusion

Melby v. Doering clarifies Montana law at the intersection of land-sale contracts and seller financing: an executed buy-sell agreement and a financing amendment remain enforceable even if the parties later fail to finalize contract-for-deed paperwork—unless the writings clearly make later execution a condition to formation. The decision also underscores that negotiated title protections constrain later “financing document” drafts: sellers cannot introduce new easements or adverse title conditions inconsistent with the approved title commitment and condition-of-title clause without risking breach.
