Article 2Interest as Damages
Section § 3287
If someone is owed money that can be calculated and they have the right to get it on a specific date, they can also claim interest from that date unless the debtor can't pay due to legal reasons or creditor's actions. This applies to all types of debtors, including government entities. If damages are awarded in a contract case where the amount wasn't clear, the court may decide on interest from a date before the judgment, but not before the lawsuit started. For tax or fee claims against a public entity, interest rate follows the U.S. Treasury yield, capped at 7% per year, until the judgment is enforceable.
Section § 3288
This law says that when someone breaks a duty that isn't related to a contract, or in cases involving severe wrongdoing like oppression, fraud, or malice, a jury can choose to award interest on any damages given.
Section § 3289
This law explains what happens to interest rates on contracts when there's a breach, or breaking, of that contract. If a contract specifies an interest rate, that rate continues to apply even after the breach, until the contract is replaced or fulfilled by something like a court judgment. If no interest rate is mentioned in a contract made after January 1, 1986, then an interest rate of 10 percent per year applies once there's a breach. However, this rule does not apply to notes that are backed by a deed of trust on real estate.
Section § 3289.5
This law states that the interest rate for a finance charge on a retail installment contract will be the legal interest rate specified in that contract, as regulated under specific laws about retail installment sales.
Section § 3290
If you accept full payment of the original amount owed to you, you lose the right to claim any interest that was supposed to be paid on that amount.
Section § 3291
This law allows someone who sues for personal injury in California to request interest on the damages they’re seeking. If the person suing makes a settlement offer that the other side rejects and then they win a better amount in court, they can earn 10% interest per year on that amount starting from the date of the settlement offer. However, this does not apply to public organizations or government employees doing their jobs, who won't be responsible for paying this interest.
