Protecting Separate Property in Montana

Montana is an equitable distribution state with a distinctive approach—after Funk v. Funk (2012), all property is subject to equitable apportionment, including premarital assets, gifts, and inheritances. Under MCA § 40-4-202, courts divide property "however and whenever acquired." But source still matters for how it's divided. Whether you're navigating an uncontested or contested divorce, understanding Montana's unique all-property approach is essential.

Montana's All-Property Approach (Post-Funk)

After Funk v. Funk (2012), Montana courts include everything in the marital estate:

• Premarital property: Subject to equitable apportionment, not automatically excluded
• Gifts and inheritances: Included in the estate, but source is a key factor
• Title doesn't control: How property is titled doesn't determine division (Engen)
• Source matters for division: While included, premarital/gifted assets are subject to special subfactors

This differs from states that exclude separate property entirely. In Montana, the question isn't "is this separate?" but rather "what equitable share should each spouse receive?"

The Special Subfactors for Premarital/Gifted Property

Under § 40-4-202(1)(a)-(c), when dividing premarital, gifted, or inherited property, courts must consider:

• (a) Homemaker contributions: Nonmonetary contributions of the homemaker spouse
• (b) Maintenance of property: Extent those contributions facilitated maintaining the property
• (c) Alternative to maintenance: Whether the division serves as an alternative to spousal maintenance

These subfactors often protect the acquiring spouse's interest in inherited or gifted property—but only if the other spouse didn't contribute to its preservation.

Active vs Passive Appreciation

Montana distinguishes between how appreciation occurred, which determines whether the non-acquiring spouse shares in it:

• Passive appreciation: Market gains or inflation—generally awarded entirely to the owner (Steinbeisser, Bradshaw)
• Active appreciation: Increases from marital efforts, preservation, or improvements—can be shared equitably (Stoneman, Herrera)
• Homemaker preservation: If homemaking enabled the other spouse to maintain the asset, that contribution counts

Example: If you inherited a rental property that doubled in value due to market forces alone, your spouse generally has no claim to that appreciation. But if marital funds paid for renovations or your spouse managed the property, that portion becomes subject to equitable division.

Commingling Doesn't Automatically Destroy Separate Origin

Unlike many states, Montana does not apply automatic transmutation when you commingle assets:

• Horton rule: In re Marriage of Horton (2004) held that commingling a gift with joint property doesn't automatically preclude treating it as separate for division
• Traceability matters: If you can establish the gift's existence and value, courts can attribute it to you despite commingling
• Practical test: If prolonged commingling makes tracing impractical (Steinbeisser), courts may treat the result as marital

This is more favorable than states with strict transmutation rules, but documentation remains critical.

Valuation Date: The Unique Circumstances Exception

Montana generally values property "at or near the time of dissolution," but the unique circumstances exception allows earlier valuation:

• Financial separation test: If parties lived "separately, financially and otherwise" (Geror, Hochhalter, Hutchins)
• Key indicators: Separate residences, separate finances, separate tax returns, no mutual contributions
• Post-separation growth excluded: If separation date is used, later appreciation belongs to the owner

Protection Strategies

• Document the source: Keep wills, gift letters, transfer statements proving premarital/gifted origin
• Maintain records: Bank statements showing the flow from gift/inheritance to current assets
• Track contributions: Document who paid for improvements, maintenance, and taxes
• Avoid active involvement by spouse: Passive appreciation stays with the owner; active involvement creates claims
• Establish financial separation early: If divorcing, separate finances quickly to invoke the unique circumstances exception
• Get baseline appraisals: Values at marriage and at acquisition support tracing claims

Key Takeaways

• All property is in: Post-Funk, premarital/gifted/inherited assets are subject to equitable apportionment
• Source matters for division: Special subfactors under § 40-4-202(1)(a)-(c) protect acquiring spouse
• Passive appreciation protected: Market gains stay with the owner absent preservation contributions
• Commingling doesn't automatically convert: Horton allows attribution if gift is established
• Title doesn't control: How property is titled doesn't determine equitable share
• Unique circumstances exception: Financial separation can justify earlier valuation date
