Negotiorum Gestio in Kuwaiti Law: Intervening for Another Without a Mandate
30 July 2026

Can someone who intervenes to save another's property claim compensation? The rules of negotiorum gestio, its conditions, the obligations of the gestor and the principal, and limits of liability.

Sometimes a person intervenes to manage an urgent matter for another without authorisation — such as repairing a neighbour's roof during their absence to prevent collapse. This intervention is called negotiorum gestio (management of another's affairs), and it is an independent source of obligation under the Kuwaiti Civil Code.

Not free volunteering: the gestor is entitled to recover expenses and compensation for any damage suffered — provided the intervention was justified and lawful.

1) The Concept

  • Definition: a person (the gestor) intentionally undertakes to manage an urgent matter for another (the principal) without being obliged to do so.
  • Independent source: a third source of obligation alongside contract and tort.
  • Justice: prevents someone who helped another from suffering loss.
  • Distinction: it is not a contract (no agreement) and not tort compensation (no fault).
Legal basis: Articles 258 to 261 of the Kuwaiti Civil Code govern negotiorum gestio.

2) Conditions

  1. Urgent matter: the action must be necessary and cannot wait.
  2. For another's benefit: the gestor must act for the principal's benefit, not their own.
  3. No obligation: the gestor must not be legally or contractually obliged to act.
  4. No mandate: the gestor acts without the principal's order or permission.
  5. Intent to manage: the gestor must intend to act for another — not merely by accident.
Urgency is essential: if the matter could wait and the principal could have been contacted, there is no gestio and no right to compensation.

3) The Gestor's Obligations

  • Reasonable care: exercising the care of a reasonably prudent person.
  • Completion: if begun, the gestor must complete the task or hand it over to the principal or their agent.
  • Notification: informing the principal of what was done as soon as possible.
  • Accounting: returning any of the principal's assets received and rendering an account.
  • Liability: liable for damage caused by negligence — but the court may mitigate liability where the urgency was justified.
Mitigated liability: the court considers the urgency of the circumstances — someone who intervenes to extinguish a fire is not held to the same standard as a professional.

4) The Principal's Obligations

  • Reimburse expenses: compensate the gestor for all expenditure incurred in managing the affair.
  • Compensate for damage: compensate for any harm the gestor suffered because of the intervention.
  • Remuneration: if the work is of a type ordinarily remunerated, the gestor is entitled to a fee.
  • Even if unsuccessful: the obligation to reimburse exists even if the intervention did not achieve its purpose — provided the gestor exercised reasonable care.
Limits: the principal's obligation is limited to the actual benefit received — they do not pay more than they gained except in special cases.

5) Scope of Compensation

Covered

  • Necessary expenses incurred.
  • Physical or material damage suffered.
  • Work fee if the task is of a remunerated type.
  • Interest on sums spent.

Not covered

  • Unnecessary or excessive expenses.
  • Acts performed for the gestor's own benefit.
  • Damage caused by the gestor's own negligence.
  • Gifts or courtesies.

6) Difference from Unjust Enrichment

  • Gestio: intentional intervention for another — creating mutual obligations between gestor and principal.
  • Unjust enrichment: unintentional enrichment or without a voluntary act — a subsidiary remedy.
  • Scope: in gestio the gestor recovers all necessary expenses — in enrichment only the lesser of two values.
  • Priority: if gestio conditions are met, its rules apply rather than unjust enrichment.
Relationship: gestio takes precedence over unjust enrichment — if its conditions are met, its specific rules apply. See unjust enrichment.

7) Practical Applications

  • Repairing a neighbour's property: fixing a water leak or crack in a neighbour's property during their absence.
  • Rescuing goods: saving another's goods from fire or flood.
  • Paying an urgent debt: paying an urgent debt to prevent seizure of the absent person's assets.
  • Animal care: feeding and caring for an absent person's animal to prevent its death.
  • Medical intervention: providing first aid to an injured person in an emergency without their consent.
Neighbourly relations: many gestio cases arise between neighbours — especially for urgent repairs affecting adjacent properties. See property sale and pre-emption.

8) Practical Guidance

If you intervened for another

  • Document what you did with photos and receipts.
  • Notify the principal as soon as possible.
  • Do not exceed what is necessary.
  • Keep receipts for everything you spent.

If someone intervened in your affairs

  • Assess whether the intervention was genuinely necessary.
  • Request an account of what was spent.
  • Pay proven necessary expenses.
  • Object to excessive expenses.
