Obligations are not uniformly simple. Some are immediate and payable at once between one creditor and one debtor. Others are suspended on an uncertain future event, or deferred to a term, or involve several parties who are jointly bound or among whom the debt is divided. Doctrine calls these characteristics the modalities of obligations, and they are not theoretical details. They determine when a debtor may be pursued, from whom the debt may be recovered, and what happens to sums paid if a condition fails. Kuwait Civil Code No. 67 of 1980 regulates them with precise rules bearing directly on contract drafting. This article explains them with practical illustrations.
Conditions: Suspensive and Resolutory
A condition is an uncertain future event on which the existence or extinction of an obligation depends:
- Suspensive condition: the obligation arises only on its fulfilment. For example, I will sell you the land if a building permit is issued for it.
- Resolutory condition: the obligation exists from the outset and produces its effects but is extinguished on fulfilment of the condition. For example, I gift you these premises on terms that the gift is revoked if you cease trading there.
- Retroactive effect: where the condition is fulfilled, its effect relates back to the time the obligation arose, so the obligation is treated as having existed or been extinguished from that time, unless the parties' intention or the nature of the contract indicates otherwise.
- The pending stage: before fulfilment the creditor holds a contingent right and may take protective steps to preserve it, such as registering a caution or seeking security.
- Void conditions: an impossible condition or one contrary to public order or morals is void, and the whole obligation may be void where the condition was the inducing motive.
- Purely potestative conditions: an obligation conditional on the debtor's mere will, such as an undertaking to pay if they choose, is void for want of seriousness.
Terms and Acceleration
A term differs from a condition in being a future event certain to occur:
- Suspensive term: it defers the enforceability of the obligation, which exists but is not payable until the term arrives.
- Resolutory term: it brings the obligation to an end, as a lease ends on expiry of its period.
- For whose benefit: a term is presumed to be for the debtor's benefit, so they may waive it and pay early, unless it appears to be for the creditor's benefit or for both.
- Payment before the term: a person who pays before the term knowing this may not recover, having impliedly waived the term.
- Loss of the term: the debtor loses the benefit of the term and the debt becomes immediately payable in defined cases, principally on a declaration of bankruptcy or insolvency, on impairing by their own act the security given to the creditor, or on failing to provide promised security.
- Practical effect: finance contracts should state acceleration events expressly, which strengthens the creditor's position and avoids argument over whether an event occurred.
Alternative and Facultative Obligations
Two situations in which the subject matter is multiple or substitutable:
- Alternative obligation: the subject matter comprises several things and the debtor is discharged by rendering one, such as an undertaking to deliver a vehicle or to pay a sum.
- Who chooses: the choice belongs to the debtor unless otherwise agreed, and where they delay the creditor may apply to the court to fix a period or to determine the choice.
- Destruction of one option: where performance of one thing becomes impossible without the debtor's fault, the obligation concentrates on the remainder.
- Facultative obligation: the subject matter is a single thing, but the debtor may be discharged by rendering another agreed thing. The distinction matters: here there is one subject matter and the substitute is merely a means of discharge.
- Effect: where the principal subject matter of a facultative obligation is destroyed by force majeure, the obligation is extinguished and the debtor is not bound to the substitute, unlike an alternative obligation.
Solidarity Among Creditors and Debtors
Solidarity addresses multiplicity of parties and is among the modalities with the greatest effect on security:
- Solidarity is not presumed: a fundamental rule. Solidarity must arise from express agreement or a statutory provision. Many creditors overlook this and find themselves facing debtors among whom the debt is divided.
- Passive solidarity among debtors: the creditor may claim the whole debt from any of them, and payment by one discharges the others towards the creditor, the payer having recourse against the others for their respective shares.
- Insolvency of one: the others bear their share in proportion to their own, which makes solidarity a strong protection for the creditor.
- Defences: a solidary debtor may raise common defences such as invalidity of the contract but not defences personal to another, such as another's incapacity.
- Active solidarity among creditors: any of them may recover the whole debt, the debtor is discharged by paying one, and the others have recourse against the recipient.
- Solidarity in tort: where several persons are responsible for a single harmful act, they are solidarily liable in damages by operation of law without any agreement.
Indivisible Obligations
Similar in effect to solidarity but different in source and nature:
- Source: indivisibility arises from the nature of the subject matter where it cannot be divided, such as an obligation to deliver a vehicle or build a wall, or from the parties' agreement to treat it as indivisible.
- Effect: each debtor is bound to perform in full and may not insist on rendering only their share.
- Distinguished from solidarity: solidarity rests on unity of the legal bond despite a divisible subject matter, whereas indivisibility rests on the nature of the subject matter itself. Most importantly in practice, indivisibility passes to heirs whereas solidarity does not necessarily do so.
- Transmission: where a solidary debtor dies, the debt is divided among their heirs according to their shares, whereas in an indivisible obligation each heir remains bound to perform in full.
Effect on Contract Drafting
These rules bear directly on what should be written into a contract:
- State solidarity expressly where there are several debtors. Wording binding the parties jointly and severally is a necessity rather than surplusage.
- Define acceleration events precisely in finance and instalment contracts.
- Distinguish clearly between condition and term in drafting, as confusing them changes the legal effect entirely.
- Avoid making an obligation conditional on a matter depending solely on the debtor's will, as the condition is void and the obligation may fall with it.
- Where a contract is made conditional, fix a period after which the condition lapses, otherwise the contract remains suspended indefinitely.
- Specify who holds the choice in an alternative obligation and the period for exercising it.
- If an obligation is divisible by nature and you wish to prevent division, state its indivisibility expressly.
The modalities of obligations are the tools by which temporal and personal balance is built into a contract, and mastering them distinguishes a sound contract from one that invites dispute. Yamnak Law Firm drafts contracts with careful control of conditions, terms, and solidarity, and handles disputes over fulfilment of conditions, acceleration, and recourse among solidary debtors.
