California Bar Conditions
Last updated: May 2, 2026
Conditions questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
A condition is an event, not certain to occur, that must occur (unless excused) before performance under a contract becomes due. Express conditions are created by contract language ('if,' 'provided that,' 'on condition that') and must be satisfied by strict compliance—substantial performance does NOT satisfy an express condition. Constructive conditions (implied by law) are satisfied by substantial performance. Conditions can be excused by waiver, estoppel, hindrance/prevention, anticipatory repudiation, impossibility, or to avoid disproportionate forfeiture (Restatement (Second) of Contracts §§224, 227, 229, 237). California follows the Restatement approach on conditions; no material California deviation is tested here.
Elements breakdown
Express Condition
An event explicitly designated by the parties' contract language as a prerequisite to a duty to perform.
- Event not certain to occur
- Designated by contract language
- Must precede the conditional duty
- Strict compliance required (no substantial performance)
Common examples:
- 'Buyer's obligation is conditioned on obtaining financing at 6% or less'
- 'Payment due upon architect's written certificate of completion'
- Satisfaction clauses ('if Buyer is satisfied with the inspection')
Constructive (Implied-in-Law) Condition
A condition supplied by the court to ensure the parties' performances are exchanged as agreed, even though the contract is silent.
- Not stated in the contract
- Supplied by court to do justice
- Tied to order of performance under §234
- Satisfied by substantial performance
Common examples:
- In a service-for-pay contract, completion of work is a constructive condition to payment
- Tender of deed in land sale is constructive condition to tender of price
Condition Precedent
An event that must occur before a contractual duty to perform arises.
- Event not yet occurred at contracting
- Must occur before duty matures
- Non-occurrence excuses performance
- Burden on party seeking to enforce duty
Common examples:
- Financing contingency in a real estate purchase
- Approval by regulatory agency before merger closes
Condition Subsequent
An event whose occurrence cuts off an already-existing duty to perform.
- Duty already in existence
- Event occurs after duty arose
- Occurrence discharges the duty
- Burden on party claiming discharge
Common examples:
- Insurance policy terminates 'unless claim filed within 60 days'
- Lease provides duty ends 'upon condemnation of premises'
Concurrent Conditions
Conditions that must occur simultaneously, with each party's performance conditioned on the other's tender.
- Both performances capable of simultaneous exchange
- Each party must tender to put other in breach
- Neither in breach until other tenders
- Common in sales of goods and land
Common examples:
- Closing of a real estate transaction (deed for price)
- Cash sale of goods under UCC §2-507/2-511
Waiver of Condition
Voluntary, intentional relinquishment of a known condition by the party whom the condition was designed to protect.
- Party benefited by condition
- Knowledge of the condition
- Voluntary intent to relinquish
- Condition is not a material part of agreed exchange
Common examples:
- Buyer closes despite seller's failure to provide a survey required by contract
- Insurer accepts late premium without objection
Excuse by Hindrance or Prevention
A party cannot rely on non-occurrence of a condition where that party's own breach of the duty of good faith caused the non-occurrence.
- Condition's non-occurrence
- Caused by party benefited by condition
- Breach of implied duty of good faith and cooperation
- Excuses the condition
Common examples:
- Buyer sabotages own loan application to escape financing contingency
- Owner refuses architect access, then claims no certificate issued
Excuse to Avoid Disproportionate Forfeiture
A court may excuse non-occurrence of a non-material express condition to prevent disproportionate forfeiture (Restatement §229).
- Express condition has not occurred
- Strict enforcement causes disproportionate forfeiture
- Condition was not a material part of exchange
- Excuse does not deprive obligee of substantial benefit
Common examples:
- Insured's one-day-late notice of loss where insurer suffered no prejudice
- Minor procedural condition in long-term contract
Excuse by Anticipatory Repudiation or Other Breach
When a party repudiates or commits a material breach, conditions to the other party's performance are excused.
- Clear, unequivocal repudiation OR material breach
- By party whose performance was conditional
- Other party's conditions are excused
- Non-breaching party may suspend or terminate
Common examples:
- Seller declares 'I won't deliver,' excusing buyer's tender of payment
- Contractor abandons job, excusing owner's duty to obtain certificate
Common patterns and traps
The Substantial-Performance-on-Express-Condition Switch
The fact pattern frames a clearly express condition (using 'if,' 'provided that,' or a satisfaction clause) and then offers a tempting answer choice that says the conditional duty is owed because the performing party 'substantially performed.' This is wrong: substantial performance is the test for constructive conditions, not express ones. The bar loves this swap because both rules are real—candidates who don't classify the condition first get baited.
Right outcome (duty owed) tied to wrong rationale ('because Liu substantially completed the work'). The correct answer instead invokes waiver, hindrance, or strict compliance.
Condition-vs-Promise Mischaracterization
Same language can be a condition, a promise, or both, and the legal consequences differ sharply. A condition's non-occurrence excuses the other party's duty; a promise's breach gives rise to damages. The trap distractor treats the language as one when it's the other—e.g., calling the financing contingency a 'promise to obtain financing' (so failure = breach) instead of a condition (so failure = no duty to close).
'Reyes is in breach because she failed to obtain financing'—when in fact financing was a condition to her duty, not a promise to perform.
The Hindrance-Excuse Blind Spot
When the party benefited by a condition takes action that causes non-occurrence, that party cannot rely on non-occurrence to escape duty. Bar distractors set up clear hindrance facts and offer a literalist answer choice ('No certificate, so no duty to pay'), inviting candidates to apply the condition mechanically and miss the implied duty of good faith.
Vignette shows obstruction of the conditioning event; wrong choice mechanically applies the condition; right choice excuses it under good-faith/prevention.
Forfeiture-Avoidance Sleeper
Restatement §229 lets courts excuse non-material express conditions to avoid disproportionate forfeiture. Candidates often miss this because it feels like 'fudging' an express condition. Watch for facts where strict enforcement of a minor procedural condition (one-day late notice, missing form) would forfeit a major benefit with no prejudice to the other side.
Minor late notice with no prejudice; trap answer applies strict compliance; right answer excuses to avoid forfeiture.
Order-of-Performance Confusion
When the contract is silent on order, courts use constructive conditions of exchange (§234): if one performance takes time and the other is instantaneous, the time-consuming performance is a constructive condition precedent to the instantaneous one. Distractors invert this (demanding payment before completion of services) or treat simultaneous performances as sequential.
'Buyer must pay before contractor finishes'—wrong because work is a constructive condition precedent to payment when no order is specified.
How it works
Conditions are about timing and sequencing: who must do what before whom. Start by asking whether the contract uses condition-creating language ('if,' 'provided that,' 'subject to,' 'on condition that')—if yes, you have an express condition that requires strict compliance. Imagine Reyes hires Liu to paint her warehouse, with payment due 'upon delivery of the architect's written certificate of completion.' If Liu finishes the job perfectly but the architect refuses to issue a certificate because Reyes locked her out of the building, the condition is excused by hindrance—Reyes can't benefit from a non-occurrence she caused. If instead the architect issues the certificate but with a typo in the date, strict compliance probably still applies, though a court might excuse to avoid disproportionate forfeiture if the typo is trivial. Watch the difference between substantial performance (enough for a constructive condition like 'finish the painting') and strict compliance (required for express conditions like the certificate). The bar tests this distinction relentlessly.
Worked examples
Will Patel likely prevail?
- A No, because issuance of the architect's certificate was an express condition precedent to payment and strict compliance is required.
- B Yes, because Patel substantially performed the renovation work to industry standards.
- C Yes, because Reyes's interference with Liu's inspection excused the condition under the doctrine of prevention. ✓ Correct
- D No, because the architect's certificate is a condition subsequent that Patel had the burden to obtain.
Why C is correct: The architect's certificate is an express condition precedent to Reyes's duty to pay, so strict compliance ordinarily would be required. But Reyes prevented the condition's occurrence by blocking Liu's access—a breach of the implied duty of good faith and cooperation. Under Restatement §245 and the prevention/hindrance doctrine, a party cannot rely on non-occurrence of a condition that party caused. The condition is excused, and Reyes's duty to pay matures.
Why each wrong choice fails:
- A: Correctly identifies the express condition and the strict-compliance rule, but ignores the dispositive excuse: Reyes herself caused the non-occurrence. Strict compliance does not protect a party who hindered the conditioning event. (The Hindrance-Excuse Blind Spot)
- B: Right outcome (Patel wins), wrong rationale. Substantial performance satisfies a constructive condition, not an express condition. The certificate is express, so Patel's quality of work doesn't substitute—the condition is excused only because Reyes obstructed it. (The Substantial-Performance-on-Express-Condition Switch)
- D: Mischaracterizes the condition. The certificate must occur before payment is due, making it a condition precedent, not subsequent. Conditions subsequent cut off existing duties; here the duty to pay had not yet matured. (Condition-vs-Promise Mischaracterization)
What is the most likely outcome?
- A Reyes Properties prevails, because Liu had a duty to obtain financing and his failure to secure a 7.0% rate constitutes breach of that promise.
- B Liu prevails, because the financing contingency was an express condition precedent to his duty to close, and the condition did not occur. ✓ Correct
- C Reyes Properties prevails, because a 7.05% rate substantially complies with the 7.0% contractual ceiling.
- D Liu prevails, because the financing condition was a condition subsequent that discharged his duty to close.
Why B is correct: The contract language ('conditioned upon Buyer obtaining a commercial loan at an interest rate not exceeding 7.0%') created an express condition precedent to Liu's duty to close. Express conditions require strict compliance: a 7.05% rate is not 'not exceeding 7.0%.' Because the condition did not occur and there are no facts suggesting Liu hindered it, his duty to close never matured, and he is not in breach. The financing contingency is a condition, not a promise, so its non-occurrence excuses performance rather than triggering damages.
Why each wrong choice fails:
- A: Mischaracterizes the financing contingency as a promise rather than a condition. Without language showing Liu promised to obtain financing (e.g., 'Buyer shall use best efforts'), the contingency is a pure condition—non-occurrence excuses Liu's duty but does not create breach liability. (Condition-vs-Promise Mischaracterization)
- C: Applies the substantial-performance doctrine to an express condition. A numerical ceiling in a financing contingency is the paradigm express condition that requires strict compliance—7.05% does not satisfy 'not exceeding 7.0%,' however close. (The Substantial-Performance-on-Express-Condition Switch)
- D: Misclassifies the condition. A financing contingency precedes the duty to close (it must be satisfied before Liu must perform), making it a condition precedent. Condition subsequents discharge already-matured duties—not the structure here. (Condition-vs-Promise Mischaracterization)
Is Reyes likely to recover?
- A No, because the 30-day notice requirement is an express condition that must be strictly complied with regardless of prejudice.
- B Yes, because strict enforcement of the notice condition would cause disproportionate forfeiture and Coastline suffered no prejudice. ✓ Correct
- C No, because Reyes had a contractual duty to provide notice within 30 days and breached that promise.
- D Yes, because Coastline waived the right to enforce the notice condition by initially investigating the claim.
Why B is correct: Even though the 30-day notice clause is an express condition, Restatement §229 permits a court to excuse non-occurrence of a non-material condition to avoid disproportionate forfeiture, provided the condition was not a material part of the agreed exchange. A two-day delay with no prejudice to the insurer is the textbook §229 scenario: enforcing strict compliance would forfeit substantial coverage rights for a trivial procedural slip. California courts apply this doctrine to insurance notice provisions consistent with the Restatement.
Why each wrong choice fails:
- A: Correctly identifies the express condition and strict-compliance default but ignores §229's forfeiture-avoidance excuse. The bar specifically tests whether you remember the equitable safety valve for non-material express conditions where the obligor suffered no prejudice. (Forfeiture-Avoidance Sleeper)
- C: Mischaracterizes the notice clause as a promise giving rise to breach damages, when it is structured as a condition voiding coverage. A condition's non-occurrence excuses the insurer's duty (no breach action against insured); the question is whether that excuse itself can be excused under §229. (Condition-vs-Promise Mischaracterization)
- D: Right outcome, wrong rationale. Waiver requires voluntary, intentional relinquishment of a known right. Coastline's preliminary investigation—especially without an express reservation issue identified in the facts—is more naturally analyzed under forfeiture-avoidance than waiver, and waiver typically requires clearer manifestation of intent to relinquish a known condition. (The Hindrance-Excuse Blind Spot)
Memory aid
WHIP-A: Waiver, Hindrance, Impossibility, Prevention, Anticipatory repudiation—the five most common excuses for non-occurrence of a condition. For classification, ask: 'IF, PROVIDED, SUBJECT TO' = express; silence + sequencing = constructive.
Key distinction
The single most important distinction: express conditions require STRICT compliance (a 99% performance fails the condition), while constructive conditions are satisfied by SUBSTANTIAL performance (a 95% performance counts). Mixing these up converts winning answers into losing ones because the legal consequence flips: under an express condition, near-miss = no duty; under a constructive condition, near-miss = duty + offset for damages.
Summary
A condition is a timing trigger, not a promise—identify whether it's express (strict) or constructive (substantial), and check for excuses (waiver, hindrance, forfeiture, repudiation) before concluding a duty hasn't matured.
