Requesting one or more guarantors from your tenant is a way to secure your rental income.

This is not an obligation, especially since more and more landlords are using a rent guarantee (GLI). However, the combination of GLI and guarantor is theoretically impossible, except if the tenant is a student or apprentice. Nonetheless, this can ensure the smooth running of your rental investment.

If you choose to make the request, here’s what you need to know. We talk interchangeably about guarantor or security for the rental lease. This can be a physical person or a legal entity. Its role - and not the least - is to pay the rent and the rental charges if the tenant were to default.

Simple guarantee or joint guarantee 👯

There are two types of guarantors:

  • the simple guarantor: the owner reminds the tenant to comply, and only in the case of accumulated debts does the guarantor intervene;

  • the joint guarantor: this is the most common, the guarantor is called upon from the first unpaid rent, without going through the tenant.

In both cases, the guarantor must therefore be solvent. The documents relating to the guarantor to be included in the rental file (identity document, tax notice, employment contract, last 3 pay slips) aim to prove their ability to fulfill their role.

The act of guarantee 📃

In order for the guarantor to be engaged, they must complete a written guarantee deed. This tripartite document (between landlord, tenant, and guarantor) can be established directly amicably or before a notary. The guarantee deed stipulates:

  • The type of guarantee: simple or joint;

  • The amounts covered by the guarantee: rent, utility charges, taxes, repairs, interest…;

  • A duration of validity (in order to avoid any inconvenience in the event of tacit renewal of the lease in particular).
