How to Build a Marital Asset Inventory

Ask a divorcing spouse what the marriage owns and you get a story. Ask for the inventory and you get silence, because almost nobody has one. Yet every consequential number in the case, support, equalization, the settlement itself, is arithmetic performed on this missing table.

A marital asset inventory is one structured list: every asset, every debt, every income stream, each with a value, a date, a source, an owner, and a classification. Building it takes a weekend of focused work from documents you mostly already hold. This guide covers the structure, the classification questions, the valuation discipline, and the ways the finished inventory gets used.

The structure: columns before rows

The inventory's power comes from its columns. Every row, whether a checking account or the house, carries the same seven attributes.

Column	Why it exists
Item and identifier	"Chase checking x4417," not "bank account." Ambiguity breeds omission.
Owner / title	His, hers, joint, or entity-held. Title affects mechanics, not necessarily classification.
Classification	Marital, separate, or disputed, with the reason noted.
Value	Current figure, net of loans against the item.
Valuation date	One consistent date policy across the table. Mixed dates skew columns silently.
Source document	The statement, appraisal, or title page behind the value.
Tax attribute	Pre-tax, post-tax, or embedded gains. Decides what the value really is.

The rows: categories people forget

• Financial accounts. Checking, savings, brokerage, CDs, and P2P wallet balances. Closed accounts stay listed with their closing disposition.
• Retirement. 401(k)s, IRAs, pensions, and deferred compensation. Pensions need present-value treatment; unvested balances still count in most states.
• Real property. Home, rentals, land, timeshares, valued net of mortgages and realistic selling costs.
• Business interests. Any ownership stake, with the entity's own assets and debts behind it. The valuation fight lives here in owner cases.
• Equity compensation. Vested and unvested RSUs, options, and ESPP holdings. The unvested grants are the ones that vanish from casual lists.
• The forgettables. Crypto, HSAs, 529 plans, life insurance cash value, tax refunds in process, loss carryforwards, security deposits, airline miles and points programs of real value, collections, tools, and loans owed to the marriage by friends or family.
• Debts. Mortgages, cards, student loans, tax debt, personal loans, with the same columns: balance, date, source, and whose name.
• Income streams and child costs. Salaries, business draws, rental income, plus tuition, childcare, and medical costs, the inputs the support modeling runs on.

The document set behind these rows is the standard divorce record: statements, returns, titles, and plan documents, all cataloged in our full document checklist. Where a row's supporting document is missing, that absence goes on the discovery list, not into a guess.

Classification: the column that gets contested

Marital property is generally everything acquired during the marriage, whatever the title says. Separate property typically covers premarital assets, inheritances, and gifts to one spouse. The mess lives in between: the inheritance deposited into the joint account, the premarital house paid down with marital income, the separate brokerage that traded actively for fifteen years. Commingling and active management convert separate property in many states, partially or wholly, and the answers turn on tracing: following the money through statements from source to destination. Mark contested rows as disputed rather than arguing them inside the table; the inventory's job is completeness first, resolution second. State frameworks are summarized at Justia's property division center.

Valuation discipline

• One date policy. Pick the valuation date your state uses and apply it to every row. Note exceptions explicitly.
• Net, not gross. The house is worth its equity after the mortgage and realistic selling costs. The 401(k) is worth its balance minus the tax embedded in it, a point that reshapes settlements per our fairness guide.
• Sources over estimates. Statement values for accounts, pricing guides for vehicles, appraisals or market analyses for property, professional valuation for any contested business.
• Version the table. Values move during a case. Date each version and keep the history; the trajectory itself sometimes becomes evidence.

Using the finished inventory

The completed table does four jobs immediately. It fills the financial affidavit from documents rather than memory, which protects you from your own omissions. It exposes the other side's: compare their disclosure against your inventory and the differences become the discovery list, with concealment leads chased through our hidden accounts guide. It powers the settlement math, since equalization is column arithmetic on this exact table. And it prices every offer in minutes: drop a proposed division onto the inventory and each side's net lands on one page.
