3.1 Louisiana Contract Requirements

Key Takeaways

  • Louisiana contracts are governed by the Civil Code; the four requisites are capacity, consent, a lawful/possible object, and a lawful cause
  • 'Cause' replaces common-law 'consideration'; immovable transfers must be in writing (an authentic act or act under private signature)
  • The Act of Sale transfers ownership; Louisiana practice executes it before a notary with two witnesses (an authentic act)
  • Lesion beyond moiety lets a seller of immovable property rescind if the price was below half the fair value, generally within one year
  • Earnest-money deposits go into the broker's trust account; standard contingencies (financing, inspection, appraisal) control cancellation

Louisiana real estate contracts are governed by the Louisiana Civil Code, so the terminology and a few doctrines differ from common-law states.

The Four Requisites of a Valid Contract

Under the Civil Code, a valid contract requires:

RequisiteMeaning
CapacityParties must be legally able to contract (18+, mentally competent)
ConsentFree, mutual agreement - not vitiated by error, fraud, or duress
ObjectA determinate thing that is lawful and possible
CauseThe lawful reason each party obligates itself (civil-law analog of consideration)

A contract to transfer an immovable must be in writing. It may take the form of an authentic act (executed before a notary and two witnesses) or an act under private signature (signed by the parties). The authentic act carries the strongest evidentiary weight and is the norm for closings.

Exam point: If a question asks for the civil-law word for "consideration," the answer is cause. If it asks what is needed for a valid contract, recite capacity, consent, object, cause.

The Act of Sale

In Louisiana, ownership of immovable property transfers by an Act of Sale, the functional equivalent of a deed. Louisiana practice executes it as an authentic act before a notary public with two witnesses, and the notary plays a central, statutorily significant role in the closing.

RequirementDetail
WrittenAlways required for immovables
NotaryA Louisiana notary executes/authenticates the Act of Sale
WitnessesTypically two witnesses to the authentic act
RecordingRecorded in the parish conveyance records to affect third parties

Civil-law note: The Louisiana notary has broader powers than a common-law notary - a Louisiana notary can draft and pass authentic acts. That is why "the notary" appears at Louisiana closings where other states use only an attorney or title company (many deals still also involve an attorney or title company).

Lesion Beyond Moiety (Seller Protection)

Lesion beyond moiety (Civil Code) lets a seller of an immovable rescind a sale when the price received was less than one-half (the "moiety") of the property's fair market value at the time of sale.

ElementDetail
Who is protectedThe seller of immovable property
TriggerPrice below 50% of fair value at sale
Time limitGenerally one year from the sale
Buyer's optionThe buyer may keep the property by paying the difference to a fair price

Example: A property worth $200,000 is sold for $90,000 (below the $100,000 half-value line). The seller may seek rescission for lesion; the buyer can defeat it by paying up to the fair value. Note that lesion protects sellers, not buyers, and applies to immovables.

Earnest Money and Common Contingencies

The standard purchase contract in Louisiana is the Louisiana Residential Agreement to Buy or Sell (widely used Louisiana REALTORS form). Earnest money / a deposit signals the buyer's commitment and is handled by the broker in the trust account - never by a salesperson and never in an operating account.

ItemRule
Where depositedBroker's trust account
TimingPromptly per the contract (commonly within a few days of acceptance)
Disputed depositBroker holds it until the parties agree in writing, interplead, or LREC/court directs release

Contingencies that govern cancellation

ContingencyEffect
FinancingBuyer may cancel and recover the deposit if financing is denied within the deadline
Inspection / due diligenceBuyer may negotiate repairs or cancel during the inspection period
AppraisalProtects the buyer if value comes in below the price
Sale of buyer's propertyConditions the purchase on selling the buyer's current home

How a contract ends

MethodDescription
PerformanceBoth parties complete obligations (closing)
Mutual consentParties agree in writing to cancel
Contingency failureA condition is not met by its deadline
DefaultOne party breaches; remedies follow the contract
Rescission/dissolutionA court unwinds the contract (fraud, error, lesion)

Trap: A salesperson must never take a deposit into a personal account or release disputed earnest money on one party's say-so.

Consent Defects: Error, Fraud, and Duress

Because consent is a requisite, Louisiana voids or unwinds contracts where consent was defective.

DefectMeaningEffect
ErrorA mistake about a fact that was the principal cause of the contractMay invalidate consent
FraudA misrepresentation or suppression of truth to gain an unjust advantageVitiates consent; damages possible
DuressConsent extracted by unlawful threat or forceVitiates consent

A contract reached through fraud, serious error, or duress can be rescinded, and fraud can also generate damages.

Deadlines and Specific Performance

Most Louisiana purchase agreements make deadlines binding. Missing one can be a default that forfeits the deposit or lets the other party cancel. If a seller wrongfully refuses to close, the buyer may sue for specific performance (a court order to transfer the immovable, since each parcel is unique) or for damages.

Exam point: A buyer's default commonly forfeits earnest money to the seller; a seller's default lets the buyer recover the deposit and seek specific performance or damages.
