Guarantor Form

The Standard Financial Backstop

A guarantor form is the document used to create a guarantor agreement (borgstelling). This is the standard method used by Dutch landlords and agents to secure a tenancy for someone who does not meet the strict income requirements on their own, such as students, recent graduates, or freelancers. A guarantor—almost always a parent or close relative—signs this separate contract. In it, they promise to cover the tenant's financial obligations to the landlord if the tenant fails to meet them. This primarily covers unpaid rent (huurachterstand), but can also extend to the cost of repairing damages to the property beyond normal wear and tear. Unlike a co-signer, a guarantor is not a party to the rental agreement itself. They are a third party providing a financial guarantee, a safety net for the landlord.

A Legally Grey Area

Despite their widespread use, the legal validity of guarantor agreements in the Dutch residential rental market is a significant and contentious grey area. The law is complex, but courts have, in a number of cases, ruled these agreements to be invalid (nietig). The reasoning can be that such an agreement unreasonably disadvantages the guarantor, or that it is an unlawful practice if the tenant actually did have sufficient income to begin with. Landlords often use guarantor agreements as a default, risk-mitigation tool, demanding one even from tenants who meet the income criteria, simply to have an extra layer of security. For the guarantor, this is a major financial risk. They are making themselves liable for potentially tens of thousands of euros, often for a contract whose terms they have little say in. While often a practical necessity to secure housing, a tenant and their potential guarantor should be aware that these forms are not as legally ironclad as landlords present them to be and are a prime example of the power imbalance in the market.
