Protecting Separate Property in Idaho

Idaho is a community property state—courts divide community property substantially equally (50/50) under Idaho Code § 32-712. However, separate property can be protected: assets owned before marriage, gifts, and inheritances remain yours under Idaho Code § 32-903. Whether you're navigating an uncontested or contested divorce, understanding Idaho's unique rules—especially that income from separate property is community—is essential.

Idaho's Community Property System

Under Idaho Code § 32-906, all property acquired after marriage is presumed community property. Key rules:

• 50/50 division: Community property is divided substantially equally unless compelling reasons exist
• Presumption of community: Assets acquired during marriage are community unless proven otherwise
• Burden on claiming spouse: You must prove separateness with "reasonable certainty and particularity"

What Qualifies as Separate Property

Under § 32-903, separate property includes:

• Premarital property: Assets owned before the marriage
• Gifts and inheritances: Property received by gift, bequest, devise, or descent during marriage
• Traceable exchanges: Property acquired with separate property proceeds

Critical Rule: Income from Separate Property Is Community

Idaho has a unique rule that differs from most community property states: under § 32-906(1), "the income, including the rents, issues and profits, of all property, separate or community, is community property."

• Rental income: If you own a rental property from before marriage, the rent collected during marriage is community
• Dividends and interest: Income generated by your separate investments becomes community
• Business profits: Distributions from a separate property business are community income

Exception: Spouses can agree in a valid written agreement that income from specific separate property will remain separate. This must be explicit—simply keeping assets in your name alone isn't enough.

Community Continues Until the Decree

Under Suter v. Suter (1976), Idaho's community does not end when you physically separate:

• Post-separation earnings: Wages earned after separation but before the decree are community property
• Acquisitions remain community: Assets purchased post-separation are still community
• Debts presumed community: Debts for family necessities incurred before the decree are presumed community

This means filing quickly may be important if you want to limit community accumulation.

Tracing Commingled Property

Idaho recognizes multiple tracing methods under cases like Papin v. Papin (2019) and Houska v. Houska:

• Direct tracing: Bank statements and escrow records showing the source of funds
• Accounting/family expense method: If community income was fully consumed by community expenses, remaining acquisitions may be inferred separate
• Standard: Prove separateness with "reasonable certainty and particularity"

Warning: If tracing is impossible, the community presumption prevails and the asset will be divided equally.

Community Lien for Enhanced Separate Property

When community funds enhance separate property, the community is entitled to reimbursement under Gapsch v. Gapsch (1954):

• Principal reduction: Community mortgage payments on separate real estate create community equity
• Improvements: Community-funded renovations that add value entitle the community to the enhancement amount (not just cost)
• Passive appreciation stays separate: Natural market gains on separate property remain separate under Hoskinson v. Hoskinson (2003)

Property disputes involving tracing and community lien calculations can increase legal costs. Idaho filing fees are approximately $207. Use our calculator to estimate your total expenses:

Protection Strategies

• Get a written agreement: Use a prenup or postnup to specify that income from separate property remains separate
• Maintain separate accounts: Keep premarital and inherited funds in accounts in your name only
• Document baseline values: Get appraisals at marriage to establish the separate portion
• Avoid commingling: Don't deposit separate funds into joint accounts
• Track all contributions: Preserve records showing which funds paid for improvements or debt reduction
• Consider reinvestment: If income is community but principal is separate, document each clearly

Key Takeaways

• Community property state: 50/50 division of community assets under § 32-712

• Income from separate is community: Unless a valid written agreement states otherwise (§ 32-906)
• No separation cutoff: Community continues until the decree (Suter)
• Tracing required: Prove separateness with "reasonable certainty and particularity" (Papin)
