Tracing Separate Property in a Texas Divorce

Separate property is not divided in a Texas divorce, but claiming it and proving it are two very different things. Texas presumes that property in either spouse’s hands is community, and the spouse who says otherwise has to prove the separate character by clear and convincing evidence. When separate money has been mixed with community money over years of marriage, the only way to meet that burden is tracing: following the asset back through every transaction to its separate origin.

Why Separate Property Has to Be Proven

Separate property includes what a spouse owned before marriage and what they received during marriage by gift or inheritance. It is not divided. But the community presumption means the law starts from the assumption that everything is community, so a spouse who wants an asset treated as separate must affirmatively prove it. Without that proof, separate property can be swept into the divisible community estate. The underlying characterization framework is covered on the property division page; this page is about how you actually carry the burden.

The Clear-and-Convincing Standard

The burden is clear and convincing evidence, meaningfully higher than the preponderance standard that governs most civil questions. It is not enough to say the money came from an inheritance; you have to show it, with records that connect the present asset to its separate source. The strength of your documentation often determines whether a separate-property claim succeeds or fails.

What Commingling Does

Commingling, mixing separate and community funds in the same account, does not automatically destroy the separate character of the money, but it makes proving it harder. Once funds are mixed, you have to demonstrate which dollars are separate, often through recognized accounting methods that identify separate funds even as money flows in and out. The more transactions and the longer the timeline, the more demanding the tracing.

The most common example that we encounter involves brokerage accounts. One spouse may have owned the brokerage account before marriage and therefore everything in that account on the day of marriage is that spouse’s separate property. But over time, the assets change value, they throw off dividends that may be reinvested, and one party or the other may make additional deposits into the account from community income.

In these scenarios, it’s tempting to look at the dollar value of the account on the date of marriage and compare it to the dollar value of the account on the day of divorce, or the day on which you are creating a property division proposal. This is not helpful analysis. Instead, look at the number of shares or units of the assets as of the date of marriage and the number of shares or units as of the date of division. The growth is probably community property.

For example, suppose you have a 401(K) that was started before marriage. Furthermore, let’s assume the participant spouse invested all contributions into an S&P 500 Index mutual fund. Now assume you have these balances:

What percentage of the account is separate property and what is community? If you look at the nominal dollar value of the account, you might divide the beginning balance by the ending balance and say that the account is 41% separate property and 59% community property. That would be completely wrong because it fails to separate growth from income (reinvested dividends and contributions) and growth from market appreciation.

The proper way to allocate the account is to say that 1,000 units (80%) are separate property and 250 (20%) units are community property. Then, on the day you are valuing the community estate, simply multiply the 250 community units by the then-current market price of the underlying instrument and that’s the amount to put on the property division spreadsheet. So, continuing the example, let’s say you are going to divide the account as of June 26, 2026 when the value of the S&P 500 was $7,354 per unit. Here are the values to use on the spreadsheet:

CORRECT

INCORRECT

To the participant spouse, this is a difference of whether they receive $3,895,080 (the wrong value) as their separate property or whether they receive $7,354,000 (the correct amount) as their separate property. If you had to pay a tracing expert $25,000 to review the statements, verify that there were no sales of shares during the marriage and that the only investment the account ever held was the lone S&P 500 mutual fund, create the trial exhibits, and write an expert report, that would be the best $25,000 ever spent because it would create an additional $3,458,920 in separate property wealth for the participant client.

Tracing Methods

Texas recognizes established methods for tracing separate funds through commingled accounts. These accounting approaches make assumptions about how separate and community dollars move when an account is drawn down and replenished, and they let an expert reconstruct the separate balance over time. Which method applies depends on the facts, and a forensic accountant typically performs the analysis and explains it to the court.

However, tracing is not the only way to establish separate property–it’s just the least nerve-wracking way from an evidentiary perspective. You can have the credible and uncontroverted testimony of the spouse who is claiming separate property as well as use some shorthand methods such as what we used in our examples above.

Records Are Everything

The practical lesson is that tracing lives and dies on documentation: account statements, closing documents, gift and inheritance records, and a clear paper trail from the separate source to the present asset. Gaps in the records are where separate-property claims collapse. If you have a separate-property claim, preserving and assembling those records early is one of the highest-value things you can do in the case.

Where This Connects

Tracing runs through many high-asset issues: retirement accounts with pre-marital contributions, a business owned before marriage, and real estate bought with mixed funds. It is also the backbone of reimbursement claims between estates.
