The Operations pillar walked you through forming the LLC. This lesson is about not un-forming it by accident. The liability shield — the "veil" between business debts and your personal assets — isn't a permanent force field the state grants at filing. It's a legal presumption that courts can set aside (piercing the veil) when the owner treats the company as a personal pocket. The good news: everything that maintains the shield is cheap, boring hygiene. The bad news: the failures are exactly the shortcuts busy owners take by default.
Education only, not legal advice. Piercing standards are state-specific and fact-heavy; an attorney should sanity-check your structure, especially once real money or real risk is involved.
Working as designed: a business creditor — the supplier, the lease, the customer who sues — collects from business assets. Your house and savings sit outside the blast radius. That's the entire economic point of the entity.
But two holes exist regardless of how clean your practices are, and owners chronically over-estimate their coverage:
What's left — ordinary business debts and claims — is real and valuable protection. If the presumption holds. Courts pierce when the entity was a fiction: no separation, no formalities, a shell run as an alter ego. Which brings us to the hygiene list.
Money separation, absolute. The classic veil-killer is commingling: business and personal money in one account, the business card buying groceries, revenue deposited personally "just this once." Separate accounts (Operations covered opening them), every dollar crossing the line labeled — owner pay as formal draw/salary/distribution (the pay-yourself lesson's machinery is veil hygiene), personal money in as documented contributions or loans, never casual transfers. If an opposing lawyer could flip through your statements and narrate "he treated it as a personal wallet," the shield is already cracked.
Sign as the company, always. Contracts name the LLC as the party; your signature block reads "Jane Doe, Member/Manager, XYZ LLC" — not bare "Jane Doe." Bare signatures can make you personally a party, PG or no PG. Same discipline on invoices, quotes, and the website: the world should constantly be told it's dealing with an entity (using the LLC name, not just a naked brand).
Keep the entity formally alive. Annual state filings and franchise fees paid (a lapsed entity can mean no shield during the lapse — Operations' annual-compliance lesson just gained stakes), registered agent current, basic records maintained: the operating agreement (yes, even single-member — it's Exhibit A that the entity is real), major decisions memorialized in short written resolutions (big purchases, loans, adding an owner), and up-to-date licenses in the entity's name.
Fund it credibly. Courts look sideways at entities set up with nothing and kept at nothing — undercapitalization — especially in businesses with obvious risk. An entity that can never possibly pay its own foreseeable obligations reads as a liability dodge, not a business. Reasonable working capital plus appropriate insurance is both good finance (this pillar's reserves lesson) and veil evidence.
One more modern leak: the "business" accounts that aren't. The PayPal on your personal email, the Venmo toggling between pizza and clients, the card-processor account opened on your SSN before the LLC existed. Migrate them into the entity's name and EIN. Every payment rail that predates the LLC is a little thread of commingling.
None of this is dramatic — that's the point. The veil is maintained in fifteen boring decisions a year, and pierced in the fifteen lazy versions of the same decisions.
