Short answer. Yes, your neighbour can sue you. Article 2180 of the Civil Code makes guardians liable for damages caused by incapacitated persons who are under their authority and live with them. You can defend by proving you observed all the diligence of a good father of a family to prevent the damage.

What the law says

Guardians are liable for damages caused by the minors or incapacitated persons who are under their authority and live in their company.

Guardians face vicarious liability for their wards

Article 2180 of the Civil Code creates a system of vicarious liability — responsibility for another person's wrongful act. It specifically addresses guardians: "Guardians are liable for damages caused by the minors or incapacitated persons who are under their authority and live in their company." Your nephew is incapacitated, he is under your authority as his legal guardian, and he lives in your home. All three conditions are met. The neighbour's car was damaged. That combination is precisely what Article 2180 covers, and the neighbour has a legal basis to sue you directly for compensation.

The underlying obligation: quasi-delict

Article 2180 builds on Article 2176, which states that whoever causes damage through fault or negligence must pay for it. The vicarious liability rules extend this principle: when the person who caused the damage is under someone else's supervision and care, the law also holds the supervisor responsible. The rationale is that guardians are in the best position to prevent their wards from harming others — they have custody, they set the rules of the household, and they can monitor behavior. The law places the financial consequence on the person who had the power to prevent the harm.

The defense available to you

Article 2180 is not a trap with no exit. The statute ends with a crucial limitation: "The responsibility treated of in this article shall cease when the persons herein mentioned prove that they observed all the diligence of a good father of a family to prevent damage." This is the due-diligence defense. If you can show that you took reasonable steps to supervise your nephew, address his condition, and prevent this kind of incident — and that despite those precautions the damage still occurred — you may escape or reduce liability. The burden is on you to prove diligence, not on the neighbour to prove negligence.

What 'diligence of a good father of a family' requires

There is no single checklist, but the standard is proportionate to the risks created by the ward's condition. For an incapacitated adult, reasonable steps might include appropriate housing arrangements, monitoring of the ward's whereabouts and activities, professional care if the incapacity is severe, and clear household protocols. The more foreseeable the risk of harm — if your nephew has a history of damaging property, for example — the more diligence the law expects. Simply being busy, or not being present when the incident happened, is generally not enough on its own to satisfy the standard.
