Paragraph 1 No maintenance calculation in force: more than one application for a maintenance calculation by the same person under section 4 or 6 or under sections 4 and 6 of the Act
Where an effective application is made or treated as made, as the case may be, for a maintenance calculation under section 4 or 6 of the Act and, before that calculation is made, the applicant makes a subsequent effective application under that section with respect to the same non-resident parent or person with care, as the case may be, those applications shall be treated as a single application.
Where an effective application for a maintenance calculation is made, or treated as made, as the case may be, by a person with care—
under section 4 of the Act; or
under section 6 of the Act,
and, before that maintenance calculation is made, the person with care—
in a case falling within head (a), is treated as making an application under section 6 of the Act; or
in a case falling within head (b), makes a subsequent effective application under section 4 of the Act,
with respect to the same non-resident parent, those applications shall, if the person with care does not cease to fall within section 6(1) of the Act, be treated as a single application under section 6 of the Act, and shall otherwise be treated as a single application under section 4 of the Act.
