Transfer ordered because action filed in wrong court: plaintiff pays transfer costs and fees within 5 days after service of notice of transfer order (else another party may pay)

If those costs and fees have not been paid by the plaintiff within five days after service of notice of the transfer order, any other party interested in the action or proceeding, whether named in the complaint as a party or not, may pay those costs and fees, and the clerk shall transmit the papers and pleadings of the action or proceeding as if those costs and fees had been originally paid by the plaintiff ... The cause of action shall not be further prosecuted in any court until those costs and fees are paid.

CCP 12: "The time in which any act provided by law is to be done is computed by excluding the first day, and including the last, unless the last day is a holiday, and then it is also excluded." CCP 12a(a): "If the last day for the performance of any act provided or required by law to be performed within a specified period of time is a holiday, then that period is hereby extended to and including the next day that is not a holiday. For purposes of this section, “holiday” means all day on Saturdays, all holidays specified in Section 135 and, to the extent provided in Section 12b, all days that by terms of Section 12b are required to be considered as holidays." CCP 12b: "If any city, county, state, or public office, other than a branch office, is closed for the whole of any day, insofar as the business of that office is concerned, that day shall be considered as a holiday for the purposes of computing time under Sections 12 and 12a." CCP 10: "Holidays within the meaning of this code are every Sunday and any other days that are specified or provided for as judicial holidays in Section 135."
