Cal. Fam. Code § 4567

The court shall then provide an opportunity for hearing, and shall thereafter enter its order exercising its discretion under all the facts and circumstances as disclosed in the admissible evidence before it so as to maximize the payment and deposit of the amount required by Section 4560, or an equivalent adequate security for the payment thereof, without imposition of undue financial hardship on the support obligor. If the court finds that the deposit of the amount required by Section 4560 would impose an undue financial hardship upon the child support obligor, the court shall reduce this amount to an amount that the child support obligor can pay as the child support security deposit without undue financial hardship.
