Montana Divorce MP-500 Property Distribution: How to Fill It Out Strategically

What the MP-500 Does and Why It Matters

The MP-500 Proposed Property Distribution is the form where you lay out exactly how you want the marital estate divided. Every asset, every debt, every piece of property you and your spouse own gets listed here, along with your proposed allocation — who gets what.

Montana District Court judges review this form to determine whether the proposed split is equitable under MCA § 40-4-202. If both parties agree and submit a joint MP-500, the judge still reviews the proposal under the applicable equitable-distribution factors. If you and your spouse disagree, each of you submits your own version, and the judge decides.

The form itself is available for free from the Montana Judicial Branch at courts.mt.gov. But the form gives you blank spaces and column headers — it doesn't tell you how to organize your assets, what values to assign, or how to structure the allocation so it satisfies the statutory factors a judge evaluates. That strategic layer is where most self-represented litigants struggle.

Before You Start: Building Your Asset and Debt Inventory

Don't sit down with a blank MP-500 and try to fill it out from memory. Build a complete inventory first, then transfer the organized data onto the form.

For every asset, you need three pieces of information:

1. What it is — real estate, bank account, retirement account, vehicle, personal property
2. Its current value — Montana courts have discretion to adopt a reasonable value supported by competent evidence; a filing-date or trial-date valuation may be relevant depending on the case
3. Its origin — was it acquired during the marriage, brought in before the marriage, or received as a gift or inheritance?

For every debt, document the current balance, the monthly payment, whose name is on the account, and whether the debt was incurred for marital purposes or one spouse's sole benefit.

Structuring the MP-500 for Judicial Approval

Montana judges evaluate property division proposals using the statutory factors in MCA § 40-4-202(1): the duration of the marriage, each spouse's age and health, their earning capacity and employability, each spouse's contribution to the marriage (including homemaking), and the needs of any custodial parent.

A well-structured MP-500 makes it easy for the judge to see that your proposal accounts for these factors. Here's how to organize it effectively:

Group assets by category. List real estate first, then financial accounts, retirement accounts, vehicles, and personal property. Within each category, show the item, its value, and which spouse you're proposing receive it. Running subtotals at the end of each category help the judge see balance at a glance.

Show the equalization math. If one spouse receives more in total value, include an equalization payment line item. For example, if Spouse A receives $180,000 in assets and Spouse B receives $140,000, an equalization payment of $20,000 from A to B brings both sides to $160,000.

Address separate property explicitly. Under Montana's all-property system, everything goes into the pool — but the court can and often does allocate separately-acquired property back to the owning spouse. If you're claiming certain assets as your separate property, list them on the MP-500 with a note about their origin. The judge needs to see them in the estate to make an equitable allocation; leaving them off entirely creates the appearance of concealment.

Include the home buyout details. If one spouse is keeping the marital home and refinancing, the refinance terms must appear on the MP-500 and be incorporated into the final decree — not in a side agreement. This is critical for Fannie Mae Rate/Term treatment, which saves thousands in interest costs. Specify the buyout amount, the refinance deadline, and the fallback if refinancing fails (typically listing the home for sale).

Common Mistakes That Get MP-500s Rejected or Challenged

Using purchase price instead of current value. The court wants fair market value now, not what you paid in 2015. For real estate, get a recent appraisal or at minimum a comparative market analysis. For vehicles, use NADA or Kelley Blue Book. For retirement accounts, use the most recent statement balance.

Forgetting debts. An MP-500 that shows only assets and ignores liabilities looks incomplete. Joint credit card balances, the remaining mortgage, car loans, student debt, and medical bills all belong on the form.

Ignoring tax-adjusted values. A $100,000 brokerage account and a $100,000 traditional IRA have different after-tax values. The brokerage account's cost basis determines the capital gains tax owed on sale, while taxable withdrawals from the IRA are generally taxed as ordinary income. Assigning both the same value on the MP-500 creates a hidden inequity.

Omitting deadlines for transfers. Vaguely stating that one spouse "will refinance the home" without a deadline gives the retaining spouse indefinite time, leaving the departing spouse liable on the mortgage. Include specific dates — refinance within 120 days, vehicle titles transferred within 30 days, retirement accounts divided within 60 days.

From Inventory to Proposal: A Practical Sequence

1. Gather every financial document — bank statements, retirement statements, mortgage payoff, vehicle titles, tax returns
2. Build a four-column ledger: item, value, Spouse A allocation, Spouse B allocation
3. Run the equalization math — do the columns balance?
4. Transfer the organized data onto the MP-500 form
5. If filing jointly, both spouses sign; if filing separately, submit your version and note where you disagree with your spouse's figures

The Montana Divorce Financial Split & Asset Division Guide includes a four-column asset allocation ledger and an MP-500 preparation workbook that walks through each section of the form — so your proposed property distribution is organized, defensible, and ready for the judge.
