Grandparents frequently provide financial support to grandchildren, particularly 'boomer' retirees enjoying stable pensions untouched by major reforms and full careers. Today's economic challenges—unemployment, part-time work, single-parent families, and soaring rents in cities like Paris—have shifted family dynamics.
Pensioners often become the sole family members with reliable income to assist divorcing children or students moving out. But can they legally stand as guarantors?
Landlords may require a guarantor if a tenant's income seems insufficient or unstable, to cover potential unpaid rent. Note: If the landlord has rent default insurance, they cannot demand both a deposit and a guarantor—except for students or apprentices.
The guarantor, named in the surety deed (acte de cautionnement), commits to paying the tenant's debts if they default.
Don't confuse this with the 'deposit' (dépôt de garantie)—a refundable sum paid by the tenant at lease signing for potential damages or repairs.
Before agreeing, assess your ability to cover payments. Landlords routinely verify guarantor solvency, requesting documents per the 2014 ALUR Law and Decree No. 2015-1437: recent tax notice, pension payment proof, property income, or investment yields.
Simple surety is uncommon: the landlord must first pursue the tenant before approaching the guarantor.
Joint and several surety lets the landlord demand payment directly from the guarantor upon default.
In either case, you're liable for rent, late interest, penalties per the lease, and repair costs for damages. Landlords rarely cap the guarantee amount.
For shared rentals with a solidarity clause (indivisibility of debt), guarantors are jointly liable. You could pay for all if one tenant defaults.
Mitigate by limiting to one named roommate via clause (rarely accepted) or insisting on individual leases—your commitment then covers only your grandchild's debts.
If unspecified or indefinite duration, terminate unilaterally via registered letter with acknowledgment (LRAR) to the landlord. It takes effect only at the end of the current lease (initial or renewal).
Upon death, heirs inherit the commitment (Civil Code art. 2294), but only for debts arising before death—even if not yet due (Cass. civ., June 10, 1997, n°95-19352). Post-death debts are excluded.
