Taxes & rules
Model contract for a private loan in the Netherlands
In short
A usable private-loan model records the parties, amount, purpose, interest, term, payment schedule, default process, security and signatures. It structures the evidence but does not by itself guarantee enforceability, tax acceptance or mortgage-interest deduction.
1. Parties, principal and purpose
Identify lender and borrower with their full legal names and addresses. State the principal, transfer date and account, and describe the purpose precisely. For an own-home loan, connect the amount to the purchase, improvement or maintenance expenditure.
Example: “The lender advances €25,000 to the borrower on 1 September 2026 for the renovation invoices listed in Schedule 1.”
2. Interest and supporting evidence
State the annual rate, whether it is fixed or variable, the fixed period or reference, payment frequency and calculation method. Attach the dated comparisons used to support the rate.
Example: “Interest is 4.5% per year, fixed for five years, calculated monthly on the outstanding principal.”
3. Repayment and early payment
Attach a schedule showing each payment and its interest and principal components. State whether additional repayment is permitted and how it changes later installments. An own-home loan may need an annuity or linear schedule within 360 months.
4. Missed payments, changes and security
Describe notice, a reasonable cure period, default interest and escalation. Require amendments in writing. Describe any guarantee or pledge accurately. A mortgage right exists only after a notarial deed and registration.
5. Signatures and records
Date and sign the same version, retain proof of the principal transfer and keep all payments and amendments with the agreement. Ask a lawyer, civil-law notary or tax adviser to review large, secured, business or disputed arrangements.
