(a) Except as provided in subdivision (b), when money is deposited as provided in this article, the court shall order the money to be deposited in the State Treasury or, upon written request of the plaintiff filed with the deposit, in the county treasury. If the money is deposited in the State Treasury pursuant to this subdivision, it shall be held, invested, deposited, and disbursed in the manner specified in Article 10 (commencing with Section 16429) of Chapter 2 of Part 2 of Division 4 of Title 2 of the Government Code, and interest earned or other increment derived from its investment shall be apportioned and disbursed in the manner specified in that article. As between the parties to the proceeding, money deposited pursuant to this subdivision shall remain at the risk of the plaintiff until paid or made payable to the defendant by order of the court.

(b) If after entry of judgment but prior to apportionment of the award the defendants are unable to agree as to the withdrawal of all or a portion of any amount deposited, the court shall upon motion of any defendant order that the amount deposited be invested in United States government obligations or interest-bearing accounts in an institution whose accounts are insured by an agency of the federal government for the benefit of the defendants who shall be entitled to the interest earned on the investments in proportion to the amount of the award they receive when the award is apportioned.
