What is the exam-ready distinction?
| Roadmap post | 199 of 500 |
|---|---|
| Official syllabus topic | Contracts: Contract Classification; Bilateral and Unilateral |
| Official PSI area | Contracts |
| Published weight | 19% of the 100-question national portion |
| Source edition | PSI Georgia Candidate Information Bulletin dated July 1, 2026 |
| Content checked through | August 2, 2026 |
The Rule
PSI publishes a weight for the complete official area, not a guaranteed count for this individual comparison. Use the source, document, actor, event, and timing stated in the question before applying a memorized definition.
Side-by-side comparison
Read across each row. The terms are deliberately compared on identical dimensions so the difference remains clear when the exam hides the vocabulary inside a scenario.
| Decision dimension | Bilateral contract | Unilateral contract |
|---|---|---|
| Exchange | Promise for promise | Promise in exchange for requested performance |
| Acceptance | Return promise creates the contract | Completion or beginning of performance as governing law provides |
| Obligations | Both parties make enforceable promises | Promisor seeks an act rather than a return promise |
| Real estate example | Ordinary purchase agreement | Broker reward or bonus offer accepted by specified performance |
Decision rule
Georgia-specific distinction
Worked example
Scenario. A seller promises to convey title, and a buyer promises to pay the agreed price at closing.
Reason it through. Each party's promise is exchanged for the other's promise.
Answer. The purchase agreement is bilateral.
Common exam traps
- Counting duties instead of promises
- Calling every reward bilateral
- Calling a drafted form unilateral
- Confusing unilateral contract with one-sided bargaining power
Original practice questions with detailed explanations
These are original instructional questions mapped to the July 1, 2026 PSI outline. They are not copied from PSI or any live examination. Choose an answer before opening the explanation.
Question 1What exchange defines a bilateral contract?
- A. Promise for completed performance only
- B. Deed for recording fee
- C. Possession for an easement
- D. Promise for promise
Show answer and explanation →
Answer: D. Promise for promise
Promise for promise is correct. A bilateral contract exchanges one promise for another, so both parties become obligated through the agreement. A unilateral contract offers a promise in exchange for requested performance rather than a return promise. Most real estate purchase agreements are bilateral because seller and buyer exchange promises to convey and pay. The rejected choices are Promise for completed performance only; Deed for recording fee; Possession for an easement. Each misses the legal category or controlling fact stated in the rule.
Question 2A seller promises to convey title, and a buyer promises to pay the agreed price at closing.
- A. The purchase agreement is bilateral.
- B. It is unilateral because the deed is delivered later.
- C. It is void until payment.
- D. It is an option merely because closing is future.
Show answer and explanation →
Answer: A. The purchase agreement is bilateral.
Each party's promise is exchanged for the other's promise. Therefore, The purchase agreement is bilateral. The other choices fail because they replace those controlling facts with a neighboring concept or an unsupported absolute rule.
Question 3What should a candidate identify first when comparing Bilateral Versus Unilateral Contract?
- A. The option with the longest definition, without classifying the facts.
- B. Ask whether acceptance occurs through a return promise or through the requested act.
- C. A memorized Georgia rule, even when the question asks for a national concept.
- D. The answer that sounds most favorable to the buyer, regardless of the document or event.
Show answer and explanation →
Answer: B. Ask whether acceptance occurs through a return promise or through the requested act.
Ask whether acceptance occurs through a return promise or through the requested act. That sequence identifies the legal category before the label. Choosing by definition length ignores the facts, importing a Georgia rule can answer the wrong jurisdictional question, and favoring one party substitutes sympathy for classification.
