Contract Basics and Required Elements

Quick Answer: Civil Code 1549 says a contract is an agreement to do or not to do a certain thing. Civil Code 1550 then lists four essentials: parties capable of contracting, their consent, a lawful object, and a sufficient cause or consideration. CDI's Bail Educational Objectives (March 2023) test the same idea as six named pieces — offer, acceptance, consideration, agreement, competent parties, and legal purpose. Offer plus absolute acceptance is how consent is shown. Miss any one piece and the paper is not a California contract, no matter how many signatures are on it.

This chapter is the Bail Bond Contracts domain: 6 questions, 8 percent of the 75-question exam. One of those six items is contract basics. The exam will not ask you to recite a hornbook. It will give a Santa Rita, Twin Towers, or Fresno County jail fact pattern and ask which element is missing, which signature is worthless, or which side deal is unlawful. Capacity, language, coercion, and duress are Chapter 8. Indemnity enforcement is Chapter 9. Premium math and trust accounts are Chapter 10. This section is formation: when does a bail deal exist at all?

Definition first, then the four (and six) elements

Civil Code 1549 is the one-sentence definition. A contract is an agreement to do or not to do a certain thing. A hallway handshake that "we'll take care of it" is not a certain thing. A numbered premium receipt that states the surety, the arrestee, the court, the penal sum, and the filed premium is.

Civil Code 1550 is the existence test. It is essential to the existence of a contract that there should be:

  1. Parties capable of contracting.
  2. Their consent.
  3. A lawful object.
  4. A sufficient cause or consideration.

CDI's six labels do not replace 1550. They unpack it. Competent parties is 1550's first item (Civil Code 1556). Offer, acceptance, and agreement are how consent is formed (Civil Code 1565, 1580, 1585). Legal purpose is the lawful object (Civil Code 1667, 1598). Consideration is 1550's fourth item (Civil Code 1605). If an item lists six elements, answer with CDI's list. If an item quotes the Civil Code, answer with 1550's four.

CDI label (exam vocabulary)Civil Code hookWhat it means in a California bail deal
Competent parties1550(1), 1556Age 18, sound mind, identifiable; not a minor signing as the indemnitor
Offer1565, 1580A definite proposal: this surety, this penal sum, this filed premium, these terms
Acceptance1585Absolute and unqualified; a "yes, but cheaper and without collateral" is a new proposal
Agreement (consent)1550(2), 1565, 1580Free, mutual, and communicated; the parties agree on the same thing in the same sense
Consideration1550(4), 1605A bargained-for benefit or prejudice: premium, a promise to appear, a promise to indemnify
Legal purpose1550(3), 1667The object is lawful; extra charges that 10 CCR 2081 does not allow are not a lawful object

Offer: a definite proposal, not a jail-lobby slogan

An offer is a manifestation of willingness to enter a bargain on stated terms, made so the other person may reasonably understand that assent will close the deal. In bail, the offer is usually the agent's (or the surety's, through the agent) proposal to effect an undertaking for a named arrestee, in a stated penal sum, at the surety's filed rate set forth on the undertaking, on stated collateral and indemnity terms. Civil Code 1580 is the meeting-of-the-minds rule: consent is not mutual unless the parties all agree upon the same thing in the same sense.

A flyer that says "bonds 24/7" is advertising, not an offer. CIC 1800.75 still forbids unlicensed advertising, but a licensed agent's yellow-page listing does not, by itself, form a contract with anyone who calls. The offer happens when terms are specific enough that a "yes" would bind: this defendant, this booking, this court, this amount, this premium, this collateral. If the family says "we'll think about it," no contract has formed. The agent may withdraw the proposal before acceptance (Civil Code 1586 and 1587 govern when a proposal may be revoked). Do not treat a quoted figure as a contract until someone accepts it.

Exam trap — the "California 10 percent" quote is not an offer of a statutory rate. There is no Insurance Code section that sets premium at 10 percent of face. 10 CCR 2081(a) lets the licensee collect the premium at the rates established by the insurer and set forth on the undertaking, or permittee charges filed under 2094. CDI's consumer page says the cost is most commonly ten percent plus allowed expenses — a market description, not a statute. An agent who offers "the 10 percent everyone charges" has not identified the lawful rate. The offer that can be accepted is the filed rate for that surety, which the agent may then rebate lower under Proposition 103 (Pacific Bonding Corporation v. Garamendi). Chapter 10 is the premium chapter; the contracts point here is that an offer of an unfiled surcharge is an offer of an unlawful object.

Acceptance: absolute, or it is a counteroffer

Civil Code 1585 is high-yield. An acceptance must be absolute and unqualified, or must include an acceptance of that character which the proposer can separate from the rest. A qualified acceptance is a new proposal. The sister who says "we'll sign if you skip the deed of trust and take fifty dollars" has not accepted. She has made a counteroffer. The original offer dies unless the agent accepts her new terms, and those new terms still have to be lawful.

Civil Code 1565 adds the communication rule. Consent must be free, mutual, and communicated by each to the other. Silence in a holding cell is not acceptance. Signing the surety's bail-bond agreement, the premium receipt, and the indemnity packet is. Performance can also accept: Civil Code 1584 treats performance of the conditions of a proposal, or acceptance of the consideration offered with a proposal, as acceptance. Posting the undertaking after the family tenders the filed premium is the classic performance acceptance — but only if the parties actually agreed on those terms.

California scenario: At the Glenn Dyer Jail in Oakland, an agent quotes the surety's filed premium on a $25,000 county-schedule bond and asks the defendant's brother to sign the indemnity agreement and a collateral receipt for the title to a 2016 Honda. The brother says, "I'll pay the premium tonight if you forget the car." That is Civil Code 1585 in a hallway. It is a new proposal. If the agent posts anyway without a meeting of the minds on collateral, the court undertaking can still bind the surety to the people (the court contract is a separate writing under Penal Code 1459), but the private collateral promise is not formed. Chapter 9 is where indemnity terms live; formation is the gate.

Agreement and free consent — formation only

"Agreement" on CDI's list is not a seventh magic word. It is consent. Civil Code 1580 requires the same thing in the same sense. The indemnitor who thinks she is signing a $2,500 premium note while the agent thinks she is signing an unlimited indemnity for a $25,000 forfeiture is not agreeing on the same thing. Civil Code 1567 lists what makes apparent consent not real or free: duress, menace, fraud, undue influence, or mistake. Those defects, plus language barriers and capacity, are the enforceability cluster in Chapter 8. For this section, memorize the formation rule: if consent is not free, mutual, and communicated, Civil Code 1550(2) is missing and no contract exists (or the contract is voidable — Chapter 8 draws that line).

Competent parties

Civil Code 1556 is the capacity statute the exam can quote: all persons are capable of contracting, except minors, persons of unsound mind, and persons deprived of civil rights. Civil Code 1557 sends minor capacity to Family Code Division 11 and unsound-mind capacity to Civil Code sections beginning at 38. A person entirely without understanding has no power to make a contract of any kind, but remains liable for the reasonable value of necessaries. In practice, the bail exam's capacity item is almost always age 18. A 17-year-old boyfriend cannot bind himself as indemnitor. The defendant who is 17 is in the juvenile system, not a commercial-bail principal on an adult undertaking.

Civil Code 1558 adds that the parties must exist and be identifiable. "The family" is not a party. Maria Lopez, date of birth, driver license number, at a stated address, is a party. A corporation can contract; a bail corporation still transacts only through licensed natural persons (Chapter 6). The surety on the court bond is the admitted surety insurer, not the trade name on the agent's jacket.

Exam trap: "The defendant already signed, so we don't need a competent indemnitor." The court undertaking can issue without an indemnitor. The private indemnity contract cannot. If the only signer is a minor, or a person who cannot identify the paper, Civil Code 1556 is the reason that indemnity is not a contract. Do not confuse that with the separate rule that the defendant is the principal on the appearance bond.

Legal purpose and 10 CCR 2081

Civil Code 1667 defines what is not lawful: contrary to an express provision of law; contrary to the policy of express law though not expressly prohibited; or otherwise contrary to good morals. Civil Code 1598 voids a contract whose single object is unlawful, wholly impossible, or so vague as to be unascertainable. Civil Code 1608 voids a promise if any part of a single consideration is unlawful.

That is how 10 CCR 2081 enters a contracts question. 2081 is a closed list. No bail licensee shall, in any bail transaction or in connection therewith, directly or indirectly charge or collect money or other valuable consideration except (a) premium at the insurer's filed rates set forth on the undertaking, or permittee charges filed under 2094; (b) collateral; (c) actual, necessary, and reasonable expenses of that transaction, including guard fees after the first 12 hours following release, listed notary/recording/long-distance/travel/posting items, with travel capped at the IRS mileage amount or the State of California employee mileage amount, at the licensee's choice; (d) actual reasonable necessary expenses caused by the arrestee's breach of the written agreement, not exceeding the penal amount; and (e) if a forfeiture is not set aside, (c) and (d) expenses incurred within 180 days of the forfeiture, in addition to the forfeiture. 10 CCR 2082 then forbids any extra service charge except as 2081(c), (d), and (e) permit.

A side agreement to pay the agent a "document fee," a "jail run fee" that is not a permitted posting or travel charge, or a renewal premium (illegal since January 1, 2022 under Penal Code 1276.1) is an agreement with an unlawful object. Civil Code 1550(3) fails. CIC 1814 can make the same conduct a public offense because it violates a commissioner rule. The contracts answer is 1667 and 2081; the criminal overlay is 1814.

Consideration

Civil Code 1605 is the definition: any benefit conferred, or agreed to be conferred, upon the promisor, by any other person, to which the promisor is not lawfully entitled, or any prejudice suffered, or agreed to be suffered, by that person other than what the person is already bound to suffer, as an inducement to the promisor, is a good consideration for a promise. Civil Code 1607 requires the consideration itself to be lawful. A gift promise with no bargained-for exchange is not a contract.

In the four bail contracts (section 7.2), consideration looks different on each paper, but each paper needs some:

  • Agent and surety: the agent gets authority to execute undertakings and earn the producer share of the filed premium; the surety gets production, a power of attorney relationship, and typically the agent's indemnity and build-up obligations.
  • Arrestee and agent/surety: the arrestee (or the person who pays) tenders the filed premium and promises to appear and keep the surety informed; the surety posts the appearance guarantee.
  • Indemnitor and agent/surety: the indemnitor promises to make the surety whole; the surety extends credit it would not otherwise extend.
  • Court and surety: the people of the State of California release the defendant from custody; the surety promises the penal sum if the defendant fails the appearance conditions in Penal Code 1459.

Premium is consideration. Collateral is security for performance, not a second premium. Mixing those two is a Chapter 11 collateral error and a 2081(a)/(b) contracts error.

When the deal must be in writing

Civil Code 1622 allows oral contracts except those the law requires to be in writing. Civil Code 1624 (statute of frauds) is the writing statute that bail actually uses. Among other categories, a special promise to answer for the debt, default, or miscarriage of another, and an agreement for the sale of real property or an interest therein, are invalid unless the contract or a note or memorandum is in writing and subscribed by the party to be charged. That is why the indemnity agreement is a signed writing, and why a deed of trust is a recorded instrument, not a handshake over a house in Stockton. 10 CCR 2084 independently requires guarantor agreements to be in writing, or reduced to writing as soon as possible after consummation. Title 10 2083 independently requires a numbered written statement of the transaction at release. The Civil Code says when an oral promise is unenforceable. The regulations say what the licensee must deliver even if someone would have been willing to deal orally.

California scenario: A cousin at the Contra Costa County jail tells the agent, "If he runs, I'll cover you — you have my word." The agent posts. The defendant fails to appear. Civil Code 1624(a)(2) is why that cousin's oral guarantee is the wrong paper. 10 CCR 2084 is why the licensee should have delivered a written guarantor agreement at signing. The court still has the Penal Code 1459 undertaking against the surety. The cousin may have no enforceable private contract.

Formation is mechanical. Identify the parties. Find a definite offer. Find an absolute acceptance. Confirm they agreed on the same thing. Confirm each had capacity. Confirm the object is lawful under the Civil Code and 10 CCR 2081. Confirm consideration moved both ways. If a writing is required, find the writing. Then — and only then — you have a California bail contract.
