You signed it on a phone, in an airport, waiting to board. A business credit card application, a cloud provider's enterprise agreement, an SBA loan, an office lease you took for one year and kept for four. Somewhere in the fine print was a sentence beginning the undersigned personally and unconditionally guarantees. You scrolled past it, because you were the business and the business was you, and the distinction felt like paperwork.

Here is the uncomfortable part. Almost everything you built has a way of dying with you — your apps go dark, your customers drift, your code sits unread. Your debt does not. It is the one asset in the whole enterprise with a genuine succession plan, and the plan is your estate.

The myth that makes people stop reading

Ask most founders what happens to business debt when you die and you'll get one of two wrong answers. The first: my kids inherit it. The second: I have an LLC, so it evaporates. Both are wrong in ways that matter, and the truth sits in the gap between them.

Your heirs do not personally inherit your debts. Nobody sends your spouse a bill for your AWS balance because she happens to be your spouse. What actually happens is that your estate — the pot of everything you owned — becomes the debtor. Your executor's job, before anyone inherits anything, is to identify valid claims, pay them from that pot, and distribute what's left. Debts don't transfer to people. They transfer to the pile, and the pile is what your family was going to receive.

So the debt doesn't chase your daughter. It just quietly reduces her.

And limited liability, the thing you formed the LLC for, does exactly what it says — right up until you waived it. Limited liability protects your personal assets from the company's obligations. A personal guarantee is the document in which you volunteer those personal assets anyway. Business credit cards for small companies are routinely issued only against a personal guarantee. So are most small-business loans, most commercial leases, and a surprising number of vendor contracts. The LLC didn't fail you. You signed a rider around it, probably more than once, and probably at a gate.

Why the guarantee is the trapdoor

A personal guarantee is a separate promise from a separate person. The company owes the money; you also owe the money, in your own name, as yourself. When you die, the company's obligation is one thing — but your obligation is a claim your creditor can file against your estate, ahead of your beneficiaries, alongside the funeral home and the hospital.

This is why the LLC's balance sheet is a bad map of your family's exposure. Your company might owe forty thousand dollars it plainly cannot pay, and a creditor looking at a dissolved single-member LLC with no assets would ordinarily shrug and write it off. But a creditor holding your signature doesn't have to shrug. They have somewhere else to look, and probate is a public proceeding that tells them exactly where.

The cruelty of it is that guarantees are invisible. There is no dashboard for them. They live in emails from 2021, in PDFs inside a vendor portal you last logged into with a password only you know, in a lease binder in a drawer. Your executor cannot pay what they cannot find, and they cannot negotiate what they don't know exists. What they will do instead is discover each one the way you discover a leak — after the ceiling stains.

The clock nobody tells the family about

Probate has a creditor claim window. After the estate opens and notice is given, creditors have a bounded period — the length varies by state, and it's typically measured in months, not years — to come forward and file. Claims filed inside the window get considered. Claims that miss it are generally barred.

This is genuinely good news, and it is the single most underused fact in solo-founder estate planning. The window is a shield. It converts an open-ended, terrifying, unknowable liability into a finite one, on a schedule, with an end date. Your family's exposure is not "forever." It's "until the clock runs out, for whoever showed up."

But it's a shield only if someone is holding it. An executor who doesn't know the estate is supposed to publish notice, doesn't know which creditors must be notified directly, and doesn't know the window exists will do the thing that feels most natural and is most dangerous: distribute assets early. Give your sister the money so she can breathe. Close it out. Be kind, quickly.

In most states, an executor who distributes an estate before valid claims are settled can be held personally liable for those claims. So the person you loved enough to name as executor pays your credit card out of their own checking account, for the crime of being generous during the worst month of their life.

The behavioral reason the list never gets written

There's a well-documented pattern in behavioral economics called the ostrich effect: people avoid checking information they expect to be unpleasant. Investors log in less often when markets fall. Patients delay opening test results. The information doesn't change based on whether you look — the discomfort does.

Debt is the most ostrich-shaped thing a founder owns. Revenue you check daily. Users you check hourly. Liabilities you check when something breaks. And a contingent liability — a guarantee that costs nothing today and everything in one specific future — is the purest form of the thing you can defer with no immediate penalty. Nothing bad happens the day you don't write the list. Nothing bad happens for years.

The other half is what researchers call the planning fallacy applied to your own continuity: we imagine the future as a version of now, with us in it, handling things. Every liability you've ever signed has always been managed by the same person — you, aware of it, servicing it, refinancing it, deciding. You've never once stress-tested the system with that person removed, because the person doing the imagining is the person who'd be gone.

Your next moves

  • Open every business credit card agreement and search the PDF for the word "guarant". Do it for the card, the loan, the lease, and any vendor contract over a few thousand dollars a year. Write down every hit — issuer, account, approximate balance, and the fact that you personally signed. This takes about forty minutes and is the highest-value forty minutes in this article.
  • Build a one-page liabilities sheet with three columns: what is owed, who to contact, and whether you personally guaranteed it. Include auto-renewing infrastructure — cloud, hosting, anything that keeps billing a dead card and accruing a balance. Your executor doesn't need your accounting. They need a phone number and a yes/no.
  • Write the sentence "Do not distribute any assets until the creditor claim period has closed — ask the probate attorney about the deadline in our state" and put it at the top of that sheet. One sentence, in plain language, aimed at a person in shock. It may save your executor from personal liability.
  • Size your term life or key person coverage against the guaranteed total, not the revenue. Insurance proceeds paid to a named beneficiary generally pass outside probate and outside the reach of estate creditors. That's the mechanism that lets your family satisfy a guarantee without selling the house.
  • Cancel one guarantee this month. Pay off and close the card you don't use. Move the lease to a month-to-month. Every guarantee you retire is one your executor never has to find.

None of this makes you immortal. It makes you legible — and legibility is the whole inheritance. A creditor with your signature will find your estate. The only variable is whether your family finds the paper first, or after it finds them.

That's the problem Heirloom was built for: a single place where the guarantees, the vendors, the accounts, and the plain-English instructions live together, so the person who has to open it isn't reverse-engineering your obligations from bank statements at two in the morning. It's a vault, a handoff, and a set of beneficiaries — the death binder for people who run everything alone. If you found a guarantee you'd forgotten while reading this, that's your sign to write it down somewhere it can be found: heirloom.lumenlabs.works.
