Legal Advice On Whether To Lend Money To A Friend’s Business (2026 Updated)

Lending money to a friend’s business can feel like a win-win. You’re helping someone you trust, and you might even earn interest or support a business you genuinely believe in.

But when money and friendship mix, things can get messy fast - especially if expectations aren’t written down, the business hits cashflow trouble, or you later discover you weren’t protected in the way you assumed.

This (2026 updated) guide walks you through the practical legal questions to ask before you lend, the common ways to structure a “friend loan” in New Zealand, and the key documents that help protect both sides from day one.

Should You Lend Money To A Friend’s Business At All?

Before we get into documents and legal structures, it’s worth taking a step back and asking the most important question: is lending money the right way to help?

Sometimes the answer is “yes” - for example, if you understand the risks, you can afford to lose the money (worst-case), and the business has a clear plan to repay you.

Other times, the kindest and safest option is to not lend at all, or to help in a different way (introductions, advice, buying products/services, or helping them access proper finance).

Common Red Flags (That Don’t Mean “Run”, But Do Mean “Slow Down”)

• It’s all urgent. If you’re being pressured to transfer money quickly, that’s a sign to pause and get clarity.
• No clear repayment plan. “We’ll pay you back when we can” is where friendships go to die.
• The business is already behind on bills or tax. That may indicate deeper cashflow issues.
• You don’t understand what you’re funding. If it’s unclear whether you’re covering stock, wages, rent, debt, or “general expenses”, you can’t assess risk properly.
• They’re offering you a return that sounds too good. High interest can be a clue that the business can’t access normal funding.

Start With A Reality Check: What Happens If You’re Not Repaid?

This sounds blunt, but it’s the best “friendship protection” question you can ask:

• If the business can’t repay you, will you be okay financially?
• If the business can’t repay you, will you still want to stay friends?
• Would you actually take legal action to recover the money if needed?

If you wouldn’t enforce the debt, you might be making a gift, not a loan. That’s fine - but you should be honest with yourself about which one it is.

What Are Your Options For Funding A Friend’s Business?

When people say “I’m lending money”, they often mean one of several different arrangements. Each option has different risk levels, and different legal paperwork.

Here are the most common ways to fund a friend’s business in NZ.

Option 1: A Straight Loan (Most Common)

You lend a fixed amount, and the business (or your friend personally) agrees to repay it. This is usually the simplest approach, and it’s often documented using a Loan Agreement.

A properly drafted loan agreement isn’t “overkill” - it’s what prevents misunderstandings later.

Option 2: You Buy Shares (Equity Investment)

Instead of being repaid like a lender, you become an owner (a shareholder) and your return depends on the business doing well (dividends or selling your shares later).

This can work well, but it’s usually more complex than people expect. You’ll want to understand:

• what percentage you’re getting,
• what rights come with those shares (voting, information rights, dividends), and
• what happens if someone wants to exit or if new investors come in.

If your friend’s business is a company, a Shareholders Agreement is often the document that sets the “rules of the relationship” between owners.

Option 3: Convertible Note Or SAFE-Style Funding

Sometimes friends want something in between a loan and equity - money goes in now, and later it may convert into shares (usually at a discount) if the business raises capital.

This is common in startups, but it can still be used for smaller businesses when everyone understands the mechanics. The key is: don’t agree to “it’ll convert later” without a document that spells out exactly how and when.

Option 4: You Act As A Guarantor (High Risk)

Occasionally a friend asks you to guarantee the business’s obligations (like a lease or a loan). This is not the same as lending money - it can expose you to a much bigger financial hit than you expect.

If you’re guaranteeing something, you need to understand what you’re guaranteeing, when the guarantee can be called on, and whether you have any realistic ability to control the risk.

This is a situation where getting tailored legal advice upfront matters.

Key Legal Issues To Think About Before You Transfer Any Money

Once you’ve decided you’re open to funding the business, the next step is to get clear on the legal and commercial basics. This doesn’t have to be awkward - it’s actually a sign you’re taking your friend’s business seriously.

Who Are You Lending To: The Company Or Your Friend Personally?

This is one of the biggest “hidden” issues in friend loans.

• If you lend to a company: your borrower is the company, not your friend personally. If the company fails and has no assets, your friend might not be personally responsible to repay you (unless there’s a personal guarantee).
• If you lend to your friend personally: your friend owes you the money, even if the business fails - but enforcing that can be uncomfortable and may still be difficult in practice.

It’s also common to have the company as borrower and the director/shareholder provide a personal guarantee (but that should be documented properly, not done informally).

Is It A Loan, Or A Gift?

If things aren’t clearly documented, disputes often turn into “you said / I said” about whether repayment was actually expected. If you want it treated as a loan, your documents and communications should consistently reflect that.

Even if you trust each other, clarity now avoids pain later.

Will You Charge Interest?

Charging interest isn’t “mean” - it can be a fair way to reflect that your money is tied up and you’re taking a risk.

If you do charge interest, your agreement should set out:

• the interest rate (and whether it’s fixed or variable),
• how it’s calculated (daily, monthly, simple vs compounding), and
• when it’s payable (monthly, at the end, or included in repayments).

If you don’t charge interest, that’s okay too - but you still want the repayment terms in writing.

What Is The Repayment Plan (And Is It Realistic)?

Repayment terms should match how the business actually operates.

For example, if your friend runs a seasonal business (like tourism, markets, or hospitality), setting a flat weekly repayment might be unrealistic. Instead, you might agree on:

• a short interest-only period,
• a delayed start date for repayments,
• a balloon payment at a certain milestone, or
• repayments linked to revenue (more complex, but sometimes workable).

Can You Call The Loan In Early?

A “repay on demand” loan sounds great for you as the lender - but it may not be realistic for the borrower. On the other hand, if you lock yourself into a long repayment period, you might regret it if your own circumstances change.

This is usually handled through clear “events of default” and acceleration rights (meaning: if certain things go wrong, you can require immediate repayment).

Are You Getting Security, Or Is This Unsecured?

An unsecured loan means you’re basically relying on goodwill and the borrower’s ability to pay. If the business goes under, unsecured lenders often sit behind secured creditors (like banks) in the repayment queue.

A secured loan may give you better protection, but it’s more formal and needs careful drafting and registration where appropriate. In some cases, a General Security Agreement can be used to secure obligations over business assets (this is an area where you should get tailored advice, because “security” that isn’t done properly can be ineffective when you actually need it).

What Should A Friend Loan Agreement Include?

If you’re lending money to a friend’s business, a written agreement is what keeps the relationship clear and reduces the risk of disputes.

At a minimum, a good loan agreement should cover the “who, what, when, and what if something goes wrong” pieces.

Core Terms To Include

• Parties: the correct legal names of the lender and borrower (and the company number if applicable).
• Loan amount: how much is being advanced and when.
• Purpose (optional but helpful): what the funds are intended for (e.g. equipment purchase, fit-out, working capital).
• Interest: the rate and how/when it’s paid (or confirm it’s interest-free).
• Term: the length of the loan.
• Repayments: dates, frequency, and payment method.
• Fees and expenses: whether the borrower pays your legal costs to prepare the documents (common in commercial loans, but sensitive with friends).
• Default and enforcement: what counts as default and what happens next.

Important “What If” Clauses That Save Friendships

This is where well-drafted agreements earn their keep. Consider including terms for situations like:

• The business is sold: does the loan need to be repaid at settlement?
• Your friend stops running the business: does that trigger repayment or a renegotiation?
• Additional borrowing: can the business take on more debt that ranks ahead of you?
• Communication and information: can you request basic financial updates while the loan is outstanding?
• Dispute resolution: a process to resolve issues before they escalate.

It can feel overly formal to add these at first, but it’s usually far less stressful than trying to negotiate them after something has already gone wrong.

Don’t Rely On Text Messages Or Templates

A text thread saying “I’ll pay you back” is better than nothing, but it’s rarely strong protection when a dispute happens - especially if key terms are missing.

And while templates can look convenient, they often miss the details that matter for your situation (like whether a director is personally guaranteeing repayment, whether you have security, and what happens if the business is restructured).

If you want to stay friends and protect your position, getting the agreement drafted properly is usually the best investment you can make.

How Does This Interact With Company Set-Up And Ownership?

Friend funding often happens at the exact moment a business is growing up - maybe your friend is moving from “side hustle” to a registered company, bringing in other investors, or signing a lease. That’s why it’s important to understand how your loan fits into the broader structure.

If They’re A Company, Check The Paperwork Matches Reality

If your friend operates through a company, it’s worth confirming:

• who the directors and shareholders are,
• who has authority to enter into contracts, and
• whether the company has any internal rules that affect borrowing.

Sometimes a company will have a constitution that sets out how decisions are made and what approvals are needed for certain actions. Where relevant, a Company Constitution can affect what the company can do and how it must approve major transactions.

If You’re Becoming An Owner, Don’t Skip The “Exit” Conversation

If you’re funding the business in exchange for shares, it’s not just about what you get today - it’s about what happens later.

For example, imagine the business takes off and your friend wants to bring in another investor. Or imagine it doesn’t work out and one of you wants out. Those are normal business scenarios, but they can be emotionally loaded when it’s friends.

This is exactly why investors and co-founders usually document the rules early, including how shares can be transferred and what happens if someone wants to exit.

Be Clear On Whether You’re A Lender Or A Partner

One of the most common sources of conflict is when the money-provider starts behaving like an owner (wanting decision-making power), while the business-owner sees it as “just a loan”.

Neither is automatically wrong - the key is to agree upfront:

• Do you get any say in how the business is run?
• Do you get information rights?
• Can they spend the money however they choose?

A clean agreement helps keep expectations aligned.

Other Legal Considerations People Often Miss

When you’re supporting a friend’s business, it’s easy to focus only on repayment. But depending on the situation, a few other legal angles can matter too.

Personal Information And Confidentiality

If your friend shares business financials, customer lists, supplier pricing, or investor discussions with you, that information may be sensitive. Even in an informal setting, it can be smart to treat it as confidential and be careful about who you share it with.

And if the business holds customer or client data, it needs to handle that properly under the Privacy Act 2020 - which is why many businesses have a clear Privacy Policy in place (especially if they collect information online).

If You’re Also Helping Out In The Business

Sometimes the lender also “chips in” by doing work - marketing, admin, sales, bookkeeping, or operational help.

That’s generous, but it can create confusion about whether you’re:

• a contractor,
• an employee, or
• effectively acting like a business partner.

If you’ll be doing regular work (even part-time), it’s worth documenting the arrangement properly so expectations are clear and both sides are protected. Depending on the set-up, that might look like a services arrangement or even an Employment Contract if there’s an employment relationship.

What If The Business Can’t Pay - Practical Next Steps

If repayments stop, the “right” next step depends on your agreement and your relationship.

In many cases, the first step is a calm conversation and a written variation to the repayment plan. If the business is still viable, restructuring repayments can be better for everyone than trying to enforce immediately.

But if the business is insolvent or heading that way, you may need legal advice early - not just to recover money, but to understand where you sit compared to other creditors and what enforcement options are realistic.

The main point is this: if you don’t have a clear written agreement, your options can be much more limited than you expect.

Key Takeaways

• Lending money to a friend’s business can be a practical way to help, but it’s important to treat it like a real commercial decision so your friendship is protected.
• Before you lend, get clear on whether you’re lending to the company or your friend personally, because that changes who is legally responsible for repaying you.
• A written loan agreement should cover the loan amount, repayment schedule, interest (if any), what counts as default, and what happens if the business is sold or can’t repay.
• If you want stronger protection, consider whether the loan should be secured, but make sure security is documented and set up correctly.
• If you’re receiving shares instead of repayment, you’ll usually need clear rules around decision-making and exits, often documented in a shareholders agreement.
• Avoid relying on text messages or generic templates - getting the terms right from day one can save you serious time, cost, and stress later.
