Just FYI - In CA they can collect child support in advance...
4560. ... every order or judgment to pay child
support may also require the payment by the child support obligor of
up to one year's child support or such lesser amount as is equal to
the child support amount due to be paid by the child support obligor
between the time of the date of the order and the date when the
support obligation will be terminated by operation of law. This
amount shall be known as the "child support security deposit."
