I had a conversation last year with a manufacturing client who had been running his business for eleven years. Good operator. Real revenue. The kind of guy who knows his shop floor better than he knows his own living room. He had built something genuinely worth protecting.
He also had no idea that the way his business was structured had left him personally exposed to a lawsuit that, if it went sideways, could have taken his house.
Not because he was reckless. Not because he skipped any obvious steps. He had an LLC. He had an accountant. He had been doing what most business owners do, which is assume that the entity structure they set up in year one is doing the job it was supposed to do.
It wasn't.
And in my experience, his situation is not unusual. It's practically the default.
The Problem Isn't That You Don't Have a Legal Structure
Most business owners I talk to at the $2M to $10M level have some form of entity in place. S-corp, LLC, maybe a C-corp if they took on early outside investment and someone talked them into it. They went to an attorney at some point, signed some paperwork, paid a filing fee, and considered the box checked.
The issue is that entity structures are not static instruments. They are living documents that are supposed to reflect how your business actually operates, who actually owns what, and where the real risk actually lives inside the organization. When the structure stops matching the reality of the business, you have a problem. And the gap between the structure on paper and the business as it actually runs tends to widen every single year, silently, while you're busy doing everything else.
I've seen it go wrong in a few distinct ways. Let me walk through the ones that come up most often.
The Single-Entity Mistake
The most common structural problem I see is the business owner who has grown a meaningful, multi-faceted operation inside a single entity. One LLC, everything inside it. The equipment, the real estate the business operates from, the intellectual property, the customer contracts, the employees.
This is fine when you're a two-person operation doing $400,000 a year. It's a serious problem when you're doing $8M and your balance sheet has real assets on it.
Here's what that looks like in practice. Let's say you're a landscaping and snow removal company. You've got a fleet of trucks and equipment worth $600,000. You own the property your shop sits on. You've got twelve employees. Everything is sitting inside one LLC.
A customer slips on a property you serviced. Or one of your trucks is in a serious accident. Or a disgruntled employee files a claim. Any one of these scenarios means that every asset inside that entity is potentially exposed to the liability event. The trucks, the real estate, the receivables, all of it is sitting in the same room as the risk.
The standard fix for this is something attorneys call an operating structure with asset protection in mind. You separate the high-risk operating activity from the assets worth protecting. Real estate goes into its own entity, typically an LLC. Equipment goes into a separate holding entity that leases back to the operating company. Intellectual property lives somewhere else. The operating company, the one that's actually touching customers and running the business day-to-day, becomes a lower-asset entity by design.
If something goes wrong in the operating company, there's less for a plaintiff's attorney to chase.
The Handshake Partnership Problem
I work with a lot of businesses that have partners. Two or three founders, or a situation where someone brought in a key person over the years and gave them equity as a way to retain them. These arrangements are often the product of a handshake, or a conversation over drinks, or a one-page agreement that hasn't been looked at since the second Obama administration.
What's usually missing is a real operating agreement that addresses what happens when things go wrong. Not just when things go well.
Who has the authority to take on debt? What happens if one partner wants out? What happens if a partner dies? What are the buyout terms? Who controls the vote when there's a disagreement about a major strategic decision? What happens if a partner gets divorced and their spouse has a claim on their equity?
That last one is not hypothetical. I have seen a partnership dispute get tangled up inside a divorce proceeding in ways that nearly froze the entire business operation. The other partners had no ability to force a clean separation because the operating agreement didn't contemplate it.
A weak or absent operating agreement isn't just a legal loose end. It is a structural liability that can paralyze your business at the exact moment when you need to be operating clearly and decisively.
The Personal Guarantee Accumulation
This one is less about entity structure in the formal sense and more about how the entity structure gets eroded over time through financing decisions.
When a business is growing, it needs capital. Banks and lenders, particularly for businesses in the $2M to $20M range, almost always require a personal guarantee on credit facilities, equipment loans, and lines of credit. That's normal. What's not normal is the business owner who has been operating for eight or ten years and has accumulated personal guarantees across five or six different credit instruments without ever sitting down to look at what the aggregate exposure actually is.
I've done this exercise with clients. We pull every credit instrument, every lease, every financing arrangement, and we map out what the personal guarantee exposure is across the full picture. In more than a few cases, the number has genuinely surprised the owner. They knew about each individual piece, but they had never added them up.
The exposure sitting inside those guarantees is real. If the business hits a rough patch, those guarantees don't care about your entity structure. They go directly to you, personally.
Part of good structural hygiene is understanding where your personal guarantee exposure lives, working to reduce it where you can as the business builds credit history and financial track record, and making sure you are not casually signing new guarantees on instruments that don't actually require them.
The Passive Owner Who Thinks They're Protected
This one is specific to people who have a minority ownership stake or a passive interest in a business they're not actively running. They often assume they're insulated from liability because they're not involved in operations.
That's not always true. Depending on how the entity is structured and what the operating agreement says, a passive owner can still carry exposure in certain scenarios, particularly if they've signed personally on any business obligations or if there are circumstances where the entity's liability protections could be challenged.
Which brings me to something that doesn't get enough attention.
Piercing the Veil Is Not Just a Legal Concept for Textbooks
Courts can, under the right circumstances, disregard your entity structure entirely and hold owners personally liable. This is called piercing the corporate veil. It sounds dramatic. It's not as rare as you'd like it to be.
The conditions that invite it are often things business owners do casually without realizing the implication. Commingling personal and business finances. Failing to maintain basic corporate formalities, like annual minutes or resolutions for major decisions. Using the business bank account as a personal slush fund. Undercapitalizing the entity from the start.
I've talked to business owners who run profitable companies and have been, for years, moving money between business and personal accounts in ways that would make an attorney very uncomfortable. Not because they're trying to hide anything. Just because it's convenient and no one ever told them it mattered.
It matters. The operational hygiene around your entity structure is part of the legal protection the structure is supposed to provide. If you're not running the entity like it's a separate legal person, a court may decide it isn't one.
So What Do You Actually Do With This
The first thing is to stop assuming the structure you set up is still the right structure. Pull out the documents. Read them. Look at your current business and ask whether the entity structure reflects how the business actually operates today.
Then get a conversation going with an attorney who does this specific kind of work, and do it alongside a financial advisor who can read your balance sheet and understand where the real asset exposure lives. These conversations work best when legal and financial are talking to each other, not in separate silos.
The things you're looking for are pretty specific. Does the structure separate high-risk operating activity from high-value assets? Does the operating agreement contemplate the actual scenarios that could disrupt the business? Do you know your total personal guarantee exposure across every instrument? Are you maintaining the basic formalities that keep the entity's protections intact?
None of this requires a complete overhaul in most cases. Sometimes it's a few targeted changes. Sometimes it's adding an entity. Sometimes it's updating an operating agreement that hasn't been touched since the business looked completely different.
The point is that you built something worth protecting. The entity structure is supposed to be the thing that protects it. If it hasn't been reviewed in three or more years, there's a real chance it isn't doing that job anymore.
