Semester 1: Lecture 10
Debt vs Equity: The Legal Difference That Changes Everything
▶ Watch the lecture
Semester 1 Course Outline
What this lecture is really about
One of the most common “quiet disasters” we see is this:
We start making money. We form a company.
And then we start moving money between us (a natural person) and the company (a separate legal entity) in a sloppy way.
That sloppy movement is where the problems begin.
So today we make it brutally simple:
There are only two clean ways to put money into a company we own or control:
Equity
Debt
Everything else is usually a messy version of one of those two.
And under stress, the law (and tax authorities, banks, accountants, courts) will force it into one bucket anyway.
The core idea
Money moving between us and the company creates classifications:
Money in → gets classified
Money out → gets classified
If we don’t classify it deliberately, someone else will classify it later.
And they won’t classify it in the way that makes us happy.
The running example (we use it all lecture)
Meet Sam.
Sam runs an online business (e-com, agency, SaaS—doesn’t matter).
He forms a company and opens a company bank account.
He owns 100%.
The business needs cash for growth: ads, contractors, inventory, runway.
So Sam wants to put $50,000 into the company.
The only real question is: What is that $50,000?
It must be either:
A) Equity, or
B) Debt
That answer matters more than Sam thinks.
Option A — Equity (plain English)
Equity means: we’re putting money into the company as permanent risk capital.
In human language, equity is basically:
“I’m funding the company as an owner.”
Key reality:
Equity is not “owed back.”
We don’t get to “take it back” just because we feel like it.
Equity is usually last in line if things go wrong.
So if the company collapses, equity often gets wiped out first.
Simple mental model:
Equity = we take risk with the company.
Equity as legal events (the state changes)
If we do it properly, it looks like this:
Decision (not the legal event yet)
We decide to inject capital as equity, ideally after sanity-checking implications (often including valuation logic, accounting treatment, future investor optics).Event > Approval
The company formally approves the issue / contribution in whatever way the company’s governance requires (director resolution, shareholder resolution, etc.).Event > Agreement
Any needed documentation is signed (share subscription, capital contribution terms, or whatever is appropriate in the jurisdiction).Event > Funds transfer
Money moves into the company bank account.Event > Issuance / register update
New shares are issued (if that’s the chosen mechanism). Registers are updated.Event > Books and records
The accounting records it as equity / paid-in capital / capital contribution.
What’s the “state change” here?
Sam can still own 100%.
The company now has $50k more equity capital.
There’s no repayment obligation just because Sam later wants cash.
Important nuance (for non-lawyers):
If we’re the only shareholder, issuing ourselves “more shares” doesn’t magically make us “more owner.” We’re still 100%. What changes is the company’s capital base and balance sheet classification.
Option B — Debt (plain English)
Debt means: the company owes us money.
In plain language:
“I’m lending the company $50,000.”
Debt is a creditor claim. It sits higher than equity in the usual priority stack.
Simple mental model:
Debt = the company must repay (on real commercial terms).
Debt as legal events (the state changes)
If we do it properly, it looks like this:
Decision (not the legal event yet)
We decide: “This is a shareholder loan.”Event > Authority
The company properly authorises the borrowing (again: resolutions / approvals as required).Event > Loan agreement signed
A loan agreement exists and is signed—even if it’s simple.Event > Payment
We transfer the $50,000 into the company account.Event > Recording
Bookkeeping records a loan payable to us.
What’s the “state change” here?
A creditor relationship exists. The company now owes us money.
“Arms length” matters (in real life)
If we say it’s a loan, it can’t be pure theatre.
We need terms that look broadly like what we’d accept from a real third party:
a plausible interest rate (or a reason why not)
repayment terms (even “on demand”)
documentation
behaviour consistent with the loan
If we don’t act consistent with it, someone will later call it what it really looked like: a distribution, salary, dividend, or just messy owner withdrawals.
What most founders actually do (the third option that ruins people)
Most new businesspeople don’t do debt or equity cleanly.
They do “later-base.”
paying company costs personally
moving money in/out whenever
using the company card for personal things
“we’ll clean it up later”
Sometimes this happens in early-stage reality. Fine.
But the danger is leaving it there. Because under stress, it collapses.
And under stress, we lose the ability to control the classification of what happened.
Why debt vs equity matters (4 big reasons)
For beginners, the differences matter for four reasons:
Priority when things go wrong
Tax treatment of money out
Disputes with partners / investors / creditors
Credibility under stress (proof beats intention)
1) Priority (who gets paid first)
When a company fails, everyone lines up.
In many systems the rough order is:
secured creditors
unsecured creditors
equity last
Debt puts us higher in the line. Equity puts us at the back.
2) Tax and reclassification risk
Founders think “money is money.”
Law thinks:
“What is this payment, legally?”
If we pull money out and call it “loan repayment” but there is no real loan:
no agreement
no ledger
no approvals
no consistent repayments
Then under stress, the payment gets reclassified.
And reclassification is where pain begins—because different labels have different consequences.
3) Disputes don’t require co-founders
Even if we’re alone today, disputes can come from:
a future investor
a lender
a partner later
a divorce
a creditor
an audit
Once another party appears, documentation stops being optional.
Debt vs equity changes the story of what happened—and the story affects the outcome.
Example:
We bring in a partner or sell equity later, and then we say:
“By the way, the company owes me $50,000.”
If the loan is clean and documented: great.
If it’s vibes: we’ve just created a fight.
4) Credibility under stress
Under stress, nobody cares what we “meant.”
They care what we did and what we can prove.
Debt requires loan paperwork + accounting record + consistent behaviour
Equity requires proper capital recording
If it’s “vibes,” we have nothing but vibes.
The practical rule we should use
Choose the bucket first. Then move the money.
Then behave consistently with the bucket.
This is not about being an accountant. It’s about not creating an avoidable mess.
Minimum viable setup (what we actually do)
Equity (beginner version)
Decide: “This is equity.” Confirm implications if needed.
Transfer money into the company account.
Record it as equity / capital contribution.
Treat it as risk capital (don’t grab it back randomly).
If we want money out later, we take it out through a clean channel (later lecture).
Equity is boring. That’s why it works.
Debt (beginner version)
We need three things:
Written document saying it’s a loan
Company books record it as a loan payable
Behaviour consistent with a loan
Loan agreement can be simple:
amount
date
parties
repayment terms (even “on demand”)
interest logic
signatures
Then we treat repayments like repayments—consistently and recorded.
If we treat the company like our wallet, the “loan” will eventually be treated like fiction.
A simple decision rule we can actually use
If we need the money back soon → Debt (document it)
If we don’t need the money back → Equity (keep it simple)
If we’re not sure → pick one and document it anyway
If we’re mixing randomly → stop and clean it up
Semester 1 goal is not perfection.
It’s clarity.
Whiteboard summary (the whole lecture in 20 seconds)
Equity: risk capital, last in line, not owed back
Debt: a creditor claim, higher priority, must be real + documented
Messy “later-base”: collapses under stress
Takeaway:
Don’t let money move between us and our company without a clear label.
Choose the bucket first. Document it. Behave consistently with it.
