Forensic Accountant vs. Tracing Software vs. DIY: What a California Divorce Actually Needs

You know which money you think is yours — pre-marital savings, an inheritance, a 401(k) you funded before the wedding. It got mixed into joint accounts, and now you have to prove it. There are three ways to do that work, and they cost wildly different amounts:

  1. Hire a forensic accountant — $2,500 to $10,000+ for a typical tracing engagement.
  2. Use tracing software — free to a few hundred dollars.
  3. Do it yourself in a spreadsheet — free, but your time and your credibility are on the line.

The honest answer is not "always pick the cheapest." It's that the three options do different jobs, and most people should use them in sequence, not choose one. This guide compares them on cost, speed, and — most importantly — what each one can actually prove in court. It's general education, not legal advice about your case.

The 60-second version

The mistake to avoid: paying $5,000 to learn what a careful first pass would have told you for free — or, the reverse, walking into a contested hearing with a spreadsheet.

Option 1: DIY — where it works and where it breaks

Building your own spreadsheet is the natural first instinct, and it has a real use: figuring out whether you have a claim at all. If you had $8,000 in savings before marriage and it's been sitting untouched in an account with your name on it, you don't need anything fancier.

DIY breaks the moment money moved. California puts the burden of proof on the spouse claiming separate property, and the courts recognize two specific tracing methods — direct tracing (See v. See) and the family-expense or exhaustion method (Marriage of Mix). A spreadsheet that just labels deposits "mine" and "ours" applies neither, and opposing counsel will say so. The common failure modes:

If your case is a DIY case, the output you want is still the same as the professionals': a range, with the evidence attached.

Option 2: Tracing software — the methodical middle

Software like Reckon exists for one recurring shape of problem:

"I had clearly separate money. It got commingled in a joint account. The other side is treating all of it as community. How much is still mine?"

That is a document-tracing problem, and it's exactly the kind of work a deterministic engine does well. From your bank, brokerage, and retirement statements, tracing software should:

Software is enough when the asset is a bank, brokerage, or retirement account (not a private business or a house), you can gather the statements, and the dispute is about classifying documented funds, not about money you think is hidden.

What it can't do is just as important. Software does not value a business, apportion a home under Moore/Marsden, chase assets someone is hiding, or take the stand. It produces evidence; it does not testify.

Option 3: The forensic accountant — when you need the human

Budget for the expert if your case looks like any of these:

The smartest play: sequence them

For most people this isn't either/or. It's an order of operations:

  1. DIY the inventory. List every account, when it was opened, and roughly what it held at marriage. Ten minutes, zero dollars. This tells you whether there's anything to trace.
  2. Run software on anything that moved. If separate money went through a joint account, get the deterministic trace, the range, and the chase list. Gather the statements it asks for.
  3. Look at the dollars at stake. A trace showing $12,000 of separate property doesn't justify a $5,000 expert. A trace showing $400,000 might.
  4. Escalate to the expert with the trace in hand. A forensic accountant's bill is largely hours × documents. Handing them an organized schedule and the statements behind it starts the clock from a running start, not a pile of raw PDFs.

You can spend $5,000 and learn your records don't support the claim. The expertise was real; the answer just wasn't in your favor. A first pass lets you find that out before the retainer check.

A quick decision rubric

Score one point for each that's true:

0 points: start with DIY and software. 1–2 points: run the software trace first, then take it to an expert for a limited-scope review. 3+ points: retain the expert now — and still hand them the trace.

What "good" output looks like, whoever produces it

The only tracing result worth trusting is a range with the evidence attached. That means a conservative floor, an aggressive ceiling, a list of what would tighten the gap, and unexplained deposits flagged rather than assumed. Anyone — a spreadsheet, a tool, or a credentialed expert — who hands you one confident number with nothing behind it should make you skeptical.

Frequently asked questions

Can tracing software replace a forensic accountant?

No. Software handles the methodical work of tracing commingled bank, brokerage, and retirement accounts and produces a court-ready schedule. It does not value businesses, apportion real estate, investigate hidden assets, or testify. For those you need a credentialed expert — and a software trace gives that expert a head start.

Is a spreadsheet good enough for a California divorce?

For deciding whether you have a claim, yes. As evidence, rarely. California puts the burden of proof on the spouse claiming separate property and expects a recognized tracing method (See v. See direct tracing or Marriage of Mix exhaustion), with each figure tied to a statement. A hand-built spreadsheet usually has neither.

How much does a forensic accountant cost compared to software?

A forensic tracing engagement in California commonly runs $2,500–$10,000, with a $3,000–$5,000 retainer and $250–$600 per hour. Tracing software is typically free for a first pass with a modest one-time fee for court-ready exports. The trade-off is scope: software traces documented funds; the accountant also values, investigates, and testifies.

Will using software first save money if I hire an expert later?

Usually. The expert's bill is mostly hours times documents. Arriving with an organized per-transaction schedule and the statements behind it means they review and extend rather than start from scratch — and the first pass tells you whether the dollars at stake justify the fee at all.

Do I still need an attorney if I use tracing software?

Yes. A trace is decision-support that shows what your records support. It is not legal advice, and the right use of it is to hand the result to your attorney, not to go it alone.
