Gov. Code, § 912.6

(a) In the case of a claim against a local public entity, the board may act on a claim in one of the following ways:

(1) If the board finds the claim is not a proper charge against the public entity, it shall reject the claim.

(2) If the board finds the claim is a proper charge against the public entity and is for an amount justly due, it shall allow the claim.

(3) If the board finds the claim is a proper charge against the public entity but is for an amount greater than is justly due, it shall either reject the claim or allow it in the amount justly due and reject it as to the balance.

(4) If legal liability of the public entity or the amount justly due is disputed, the board may reject the claim or may compromise the claim.

(b) In the case of a claim against a local public entity, if the board allows the claim in whole or in part or compromises the claim, it may require the claimant, if the claimant accepts the amount allowed or offered to settle the claim, to accept it in settlement of the entire claim.

(c) Subject to subdivision (b), the local public entity shall pay the amount allowed on the claim or in compromise of the claim in the same manner as if the claimant had obtained a final judgment against the local public entity for that amount, but the claim may be paid in not exceeding 10 equal annual installments as provided in Section 970.6 only if the claimant agrees in writing to that method of payment and in such case no court order authorizing installment payments is required. If an agreement for payment of the claim in installments is made, the local public entity, in its discretion, may prepay any one or more installments or any part of an installment.
