Trust Accounting In Orange County: Why DIY Could Cost You More Than You Think

There’s a good reason why trust accounting is often described as “simple, but not easy.” The rules are out there, the forms are available, and there’s no shortage of online advice. But for trustees in Orange County, especially those overseeing high-value trusts, the do-it-yourself route can quietly become a ticking time bomb.

At Donna L. Stern, C.P.A APC, we’ve seen this pattern more times than we can count: a well-meaning trustee tries to keep things “in house,” only to find themselves stuck in a complicated mess.

So let’s talk about why cutting corners with trust accounting isn’t saving you anything—and how a professional CPA can help protect not just your finances, but your reputation.

What Is Trust Accounting, Really?

If you’re reading this, you probably already know that trust accounting isn’t just a spreadsheet with a few notes. It’s a formal, legally required report detailing every financial move you make as a trustee.

A trust accounting typically includes:

  • Beginning trust balance
  • Itemized income (rent, interest, dividends, etc.)
  • Disbursements (bills, distributions, taxes)
  • Gains and losses on investments
  • Ending trust balance
  • Supporting documents (bank statements, receipts, etc.)
  • And…potentially change of form assets

In California, the Probate Code outlines very specific rules around how this is done and when. For most trustees, that means providing an accounting annually, upon request, and when the trust terminates.

Miss something? That could open the door for more challenges than an awkward holiday get-together.

The Myth of “It’s Just Numbers”

Here’s where a lot of people get tripped up.

They assume trust accounting is just a fancier version of managing a personal budget or business books. After all, if you’ve balanced a checkbook or handled QuickBooks, how hard can it be?

The reality: trust accounting exists in its own world. It’s not just about “keeping track”—it’s about complying with specific standards that are enforced by the courts. And they don’t care how good your spreadsheet looks if it doesn’t follow the rules.

This is where the trouble begins for many DIY trustees.

Common DIY Mistakes We See

If you’re handling a trust of any size, even a small mistake can have major consequences. Some of the most common issues we encounter include:

  1. Commingling Funds

This is when personal and trust funds are mixed together—even temporarily. It makes the accounting even more complicated and can rack up more legal fees and accounting fees unwinding what was done.

  1. Improper Disbursements

Paying for things that aren’t allowed under the trust’s terms or not documenting them properly. Even if your intentions are good, this looks bad.

  1. Missed Deadlines

California law requires timely accountings. Waiting until the last minute or ignoring requests from beneficiaries is an open invitation for legal trouble.

  1. Lack of Documentation

You need to back up every entry with records. 

  1. Wrong Accounting Format

There’s a specific way trust accounting should be presented in California, governed by the California Probate Code. Using the wrong format could get your report rejected outright.

The Real Cost of DIY

Let’s put it plainly: the idea of “saving money” by handling trust accounting on your own only works if everything goes perfectly. One wrong turn, and it can cost you thousands.

Here’s a common scenario we see:

  • A trustee tries to DIY an accounting for a trust.
  • Misses some reporting requirements, mixes up a few distributions.
  • One beneficiary consults a lawyer after noticing inconsistencies.
  • The trustee is now facing scrutiny.
  • A professional is finally brought in to fix what could have been done right the first time.

End result? The trustee ends up spending far more money fixing the problem than they would have if they had hired expert help at the start.
