Interim maintenance may be allowed during pendecy of petition for final award of maintenance .

As the name itself suggests 'interim' means for a temporary period or for immediate stop gap arrangement and the interim maintenance is awarded to sustain till the time final award of maintenance is delivered during the pendency of petition and the maintenance granted would be after the final verdict.

interim maintenance is granted during pendency of petition so that party can sustain itself till petition is heard and finally disposed of . final maintenance would be granted at the time of disposal of proceedings

1. Interim maintenance is granted before the application for maintenance is heard & decided upon,

2. Maintenance is what is granted finally after hearing the maintenance petition.

Nothing more to add.
