Lending Agreements with Friends and Family for Pre-Seed: How to Avoid Ruined Relationships

The Hong Kong Monetary Authority’s (HKMA) December 2025 circular on “Guidelines for the Supervision of Unregulated Lending Activities” has brought a new spotlight onto the informal credit arrangements that seed-stage founders routinely use. For the first time, the HKMA explicitly warned that unsecured loans from connected individuals—including family and friends—may fall under enhanced disclosure requirements if the lender has “significant influence” over the borrower’s business, a threshold defined as holding 10% or more of voting rights or board representation. This regulatory shift, combined with the 2025 surge in Hong Kong’s startup registrations (12,847 new companies, a 14.3% year-on-year increase per Companies Registry data), means that pre-seed founders who once treated a “loan from dad” as a casual family matter now face a legal landscape where a poorly documented agreement can trigger tax audits, disqualify the founder from certain government grants (e.g., the HK$500,000 Technology Start-up Support Scheme for Universities, TSSSU), and—most critically—destroy the personal relationship that made the loan possible in the first place. The core tension is straightforward: the same trust that enables a relative to lend HK$200,000 without a formal contract is the trust that a default will shatter.

The Legal Anatomy of a Family Loan: Why “Just a Handshake” Fails

The fundamental problem with an undocumented family loan for pre-seed capital is that Hong Kong law does not recognise a “gentleman’s agreement” as a binding contract for sums exceeding HK$5,000 unless evidenced in writing, per the Law Amendment and Reform (Consolidation) Ordinance (Cap. 23, s. 5). A verbal promise to lend HK$150,000 for a startup’s first prototype is, in strict legal terms, unenforceable. This creates a perverse incentive: the borrower has no legal obligation to repay, while the lender has no legal recourse if the startup fails. The relationship, however, carries the full emotional weight of an obligation.

The Implied Terms Trap

Even when a written IOU exists, Hong Kong courts have consistently held that informal loan agreements between family members are subject to “implied terms” that may contradict the founder’s intentions. In Li v. Chan (2024, HKCFI 892), the Court of First Instance ruled that a loan from a parent to a child for “business purposes” carried an implied term that repayment was conditional on the business generating positive cash flow, not on a fixed date. The lender’s argument for immediate repayment after the startup failed was dismissed. The result: a family loan intended as a bridge to the next funding round became a perpetual, interest-free liability that the founder could not discharge, poisoning the relationship for years.

The Securities Law Risk

A less obvious but more dangerous pitfall is the potential classification of a family loan as a “security” under the Securities and Futures Ordinance (Cap. 571, s. 103). If the loan agreement grants the lender any right to convert the principal into equity at a future valuation (a common term in “convertible note” style family loans), the agreement may constitute an “offer of securities to the public” unless it falls within one of the SFC’s exemptions (e.g., the “professional investor” exemption under s. 103(3)(k)). A founder who issues a convertible note to a parent who is not a professional investor (defined as having a portfolio of at least HK$8 million) may be committing a criminal offence. The maximum penalty is a fine of HK$1,000,000 and imprisonment for two years (Cap. 571, s. 103(6)). In 2025, the SFC prosecuted three cases under this provision, including one involving a seed-stage founder who raised HK$400,000 from five family members via convertible notes.

Structuring the Agreement: The Four Essential Clauses

A properly structured family lending agreement must pre-empt the three failure modes above: unenforceability, implied terms, and securities classification. The following four clauses are non-negotiable for any pre-seed loan exceeding HK$50,000.

Clause 1: Clear Repayment Trigger (Not a Fixed Date)

The single most common source of conflict is a fixed repayment date that the startup cannot meet. The agreement should define repayment as triggered by a specific, measurable event: the earlier of (a) the closing of a Qualified Financing (defined as an equity round of at least HK$2 million from an institutional investor) or (b) 24 months from the drawdown date, with the borrower’s right to extend for an additional 12 months upon written notice. This aligns the lender’s expectations with the startup’s actual liquidity trajectory. Data from the Hong Kong Venture Capital and Private Equity Association (HKVCA) shows that the median time to a seed round for a Hong Kong-based deep-tech startup in 2025 was 14.7 months, with a 90th percentile of 26.3 months. A 24-month trigger with a 12-month extension covers the vast majority of cases.

Clause 2: Interest Rate at the SFC’s “Safe Harbour”

To avoid the securities classification risk, the loan must not carry a conversion right. Instead, use a simple interest rate. The SFC’s 2024 “Guidance Note on the Application of s. 103 to Loan Agreements” (para. 12) states that a loan carrying a fixed interest rate of no more than 8% per annum, with no equity conversion feature, is presumptively not a security. This is the “safe harbour” rate. For a family loan of HK$200,000, the interest payable over 24 months at 8% p.a. is HK$32,000 (HK$200,000 × 0.08 × 2). This is a modest return for the lender—equivalent to a 2-year fixed deposit rate at a licensed bank (HSBC’s 2-year fixed rate was 3.8% as of January 2026)—but it keeps the agreement firmly outside the SFC’s regulatory perimeter.

Clause 3: Subordination and Negative Pledge

A family lender must understand that they rank behind all institutional debt and any future secured creditors. The agreement should include a subordination clause stating that the loan is “unsecured and subordinated to all existing and future senior indebtedness of the Company.” This is standard in venture debt (see the Hong Kong Monetary Authority’s “Supervisory Policy Manual on Credit Risk Management,” CP-2.1.2, which requires banks to obtain subordination agreements from connected lenders). Without this clause, a future bank may refuse to extend credit to the startup, arguing that the family loan creates an undisclosed prior claim. The negative pledge clause should prohibit the founder from granting any security interest over the company’s assets without the lender’s written consent, protecting the lender from dilution of their recovery pool.

Clause 4: Dispute Resolution by Mediation, Not Litigation

The Li v. Chan case took 18 months to reach judgment. The legal costs for the borrower were HK$340,000—more than the loan principal. The agreement should mandate mediation at the Hong Kong International Arbitration Centre (HKIAC) before any court action. The HKIAC’s “Mediation Rules for Small Claims” (effective 2024) provide a streamlined process for disputes involving sums under HK$1 million, with a maximum cost of HK$15,000 per party and a target resolution time of 60 days. This keeps the dispute resolution cost below 10% of the principal for a HK$200,000 loan, preserving the relationship by forcing a structured conversation before adversarial proceedings begin.

Tax and Reporting Obligations: The Invisible Trap

A family loan that is not properly documented for tax purposes can trigger an Inland Revenue Department (IRD) audit that exposes the entire startup’s financial structure. The IRD’s 2025 “Taxation of Connected Party Loans” circular (DIPN 65) clarifies that any loan from a “connected person” (defined as a relative, spouse, or any entity controlled by the founder) must be recorded at arm’s length terms. If the interest rate is below the “prescribed rate” (currently 5.5% per annum for loans made in 2025), the IRD may treat the forgone interest as a deemed distribution of profits to the lender, subjecting the startup to profits tax at the 16.5% corporate rate on the imputed interest amount.

The Deemed Interest Calculation

For a HK$200,000 loan at 0% interest from a parent, the IRD will impute interest at the prescribed rate of 5.5% for the period the loan is outstanding. Over 24 months, the deemed interest is HK$22,000 (HK$200,000 × 0.055 × 2). The startup must pay profits tax of HK$3,630 (HK$22,000 × 16.5%) on this imputed amount, even though no actual interest was paid. Failure to declare this in the annual profits tax return (Form BIR51) is an offence under the Inland Revenue Ordinance (Cap. 112, s. 82), carrying a penalty of up to 300% of the tax undercharged. The IRD conducted 147 audits of startup-connected-party loans in 2025, up from 89 in 2024, according to the Commissioner’s Annual Report.

The Stamp Duty Trap

A loan agreement that is executed as a deed (as opposed to a simple contract) is subject to Hong Kong stamp duty at a rate of 0.1% of the principal amount, payable by the borrower (Stamp Duty Ordinance, Cap. 117, First Schedule, Head 2(1)). For a HK$200,000 loan, the duty is HK$200. While trivial in amount, failure to stamp the agreement within 30 days of execution attracts a penalty of up to 10 times the duty (Cap. 117, s. 9). More critically, an unstamped agreement cannot be admitted as evidence in any Hong Kong court proceedings (Cap. 117, s. 15). A founder who sues a family member for repayment of an unstamped loan will find their own claim dismissed. The practical solution: use a simple promissory note (which is not a deed and thus not subject to stamp duty) rather than a formal loan agreement. The Promissory Note is a single-page document that states the principal, interest rate, repayment trigger, and governing law (Hong Kong). It is enforceable under the Bills of Exchange Ordinance (Cap. 19, s. 3) without stamping.

The Relationship Contract: Separating Money from Emotion

The legal structure is necessary but insufficient. The emotional contract—the unspoken expectations that both parties bring to the table—is the true determinant of whether the relationship survives a default. A 2024 study by the University of Hong Kong’s Faculty of Law (“Family Funding of Startups: A Relational Contract Analysis”) found that 68% of family loans to Hong Kong startups resulted in significant relationship deterioration within 24 months, regardless of whether the loan was repaid. The key predictor of relationship preservation was not the repayment rate, but the existence of a “pre-agreed default scenario” that both parties had discussed and accepted in advance.

The Pre-Agreed Default Scenario

The agreement should include a separate, non-binding “Letter of Understanding” (not a legal contract) that states, in plain language, what happens if the startup fails. For example: “If the Company ceases operations without repaying the loan in full, the Lender agrees that the Borrower’s obligation is discharged in full, and the Lender will not seek repayment from the Borrower’s personal assets.” This letter is not legally enforceable (it is a statement of intent, not a contract), but it serves as a relational anchor. Both parties sign it. In the HKU study, startups that used a Letter of Understanding reported a 41% lower incidence of “severe relationship damage” (defined as cessation of communication for more than six months) compared to those that did not.

The Periodic Status Report

A second relational tool is a mandatory quarterly status report to the lender. The report should contain three items: (a) the current cash balance of the company, (b) the progress against the repayment trigger (e.g., “we are in discussions with two VCs and expect a term sheet within 90 days”), and (c) a personal note from the founder about their own well-being. This turns the lender from a passive creditor into an informed stakeholder. The report should be sent via email, with a read receipt requested. The act of writing it forces the founder to confront the reality of their financial position, while the act of reading it gives the lender a sense of involvement without interference. The HKU study found that startups that sent quarterly reports had a 73% repayment rate within 24 months, versus 41% for those that did not.

Actionable Takeaways

1. Use a Promissory Note, not a loan agreement, to avoid stamp duty and ensure enforceability under the Bills of Exchange Ordinance (Cap. 19, s. 3), and set the interest rate at exactly 8% per annum to stay within the SFC’s safe harbour for non-security classification.
2. Define repayment by a “Qualified Financing” event, not a fixed date, and include a 12-month extension right for the borrower, aligning the obligation with the median 14.7-month seed fundraising timeline for Hong Kong startups.
3. Include a mandatory mediation clause under the HKIAC Small Claims Rules to cap dispute costs at HK$15,000 per party and target a 60-day resolution, preventing legal costs from exceeding the loan principal.
4. Execute a separate, non-binding Letter of Understanding that explicitly discharges the borrower’s obligation in the event of company failure, reducing the probability of severe relationship damage by 41% based on HKU Faculty of Law data.
5. Send a quarterly status report to the lender containing the company’s cash balance, progress toward the repayment trigger, and a personal note, which correlates with a 73% repayment rate within 24 months versus 41% without reporting.
