Marital Property vs Separate Property in Maine

The classification of assets as marital or separate is the single most consequential decision in a Maine divorce property division. Once an asset is classified as marital, it goes into the equitable distribution pool under 19-A M.R.S. § 953. Once it's classified as separate, it's set aside to the owning spouse and is not divided.

Getting this wrong — or failing to document it — can cost you tens or hundreds of thousands of dollars.

What Is Marital Property?

Maine law presumes that all property acquired by either spouse during the marriage is marital property, regardless of how the title is held. If your name is the only one on the deed, the bank account, or the brokerage statement, it does not matter. If you acquired it during the marriage with marital income, it is marital.

This includes the family home, vehicles, savings, retirement contributions made during the marriage, business interests developed during the marriage, and even the cash value of life insurance policies.

What Is Separate Property?

Under § 953(2), separate property includes:

• Pre-marital assets — property you owned before the marriage date
• Gifts and inheritances — assets received by one spouse individually through gift, bequest, devise, or descent
• Property excluded by agreement — assets protected by a valid prenuptial or postnuptial agreement
• Assets acquired in exchange for pre-marital or gifted/inherited property
• Passive appreciation on separate property — market-driven growth (interest, inflation, stock market gains) on assets you kept separate

The critical word is "passive." If the separate asset grew because of marital effort or marital funds, that growth becomes marital property.

How Separate Property Becomes Marital

This is where most people get caught. Maine law recognizes several ways separate property loses its protected status:

Commingling

Depositing an inheritance into a joint bank account. Using pre-marital savings to fund joint expenses. Mixing separate funds with marital funds in any way that makes them impossible to trace back to their separate source.

Once funds are commingled, the burden shifts to you to prove which portion is separate through detailed tracing — bank statements, transaction records, and a clear paper trail showing the separate funds were never mixed. Without that evidence, the court will treat the entire commingled account as marital.

Transmutation (Joint Title Gift Presumption)

If you owned a home before the marriage and later added your spouse to the deed, Maine law presumes you intended to gift that property to the marital estate. This is the "joint title gift presumption," and rebutting it requires clear and convincing evidence that you never intended to make a gift — a high bar.

The same logic applies to adding a spouse's name to a pre-marital investment account, car title, or business entity.

Active Appreciation

Under § 953(2)(E), the increase in value of a separate asset becomes marital property if either spouse played a "substantial active role" in managing, preserving, or improving it during the marriage.

Example: You owned a rental property before marriage. During the marriage, you used marital income to renovate it and your spouse managed the tenant relationships. The property's value increased from $200,000 to $350,000. The $150,000 in appreciation is likely marital property because it resulted from marital labor and funds — even though the underlying property was pre-marital.

By contrast, if a pre-marital stock portfolio grew from $100,000 to $140,000 purely through market gains with no active management, that $40,000 in passive appreciation remains separate.

Protecting Your Separate Property

If you have assets you believe are separate, take these steps before or early in the divorce process:

1. Gather original documentation — the deed, account statement, or gift letter showing when and how you acquired the asset
2. Trace the funds — if separate money was ever deposited into a joint account, build a transaction-by-transaction trail showing the source and destination of those funds
3. Document passive vs. active growth — show whether any increase in value came from market forces or from marital labor/investment
4. Check for transmutation — if you added your spouse to any title or account, prepare to explain the circumstances
5. Disclose everything on FM-043 — the sworn Financial Statement requires you to list all assets and classify them; this is your opportunity to formally assert which assets are separate

The Maine Divorce Financial Split Guide includes a separate property tracing ledger and commingled asset diagnostic worksheet designed specifically for Maine's § 953 classification rules — so you can build your evidence file before the 21-day disclosure deadline hits.
