Adjust line spacing

This brief needs consistent spacing for legal filing. Set the body text to single-spaced, make the gap after each paragraph 6 points, ensure headings remain double-spaced above and below, and apply these changes across the whole document without altering character spacing or the pagination of exhibits.

Before I hand this to Court Services, make the spacing crystal: highlight any paragraphs that are accidentally double-spaced, surface the sections where different styles conflict, recommend which style to keep for consistent filing, and note any places where changing spacing will push exhibits onto a new page.

I just switched the document style and now reviewers say some paragraphs are too tight while others are loose. I need to file this by Monday and I cannot reflow exhibits. What probably caused inconsistent line and paragraph spacing, what three fixes get uniform spacing without breaking pagination, and what should I watch for when I reapply the style?

Every filing I end up chasing spacing issues at the last minute and that often shifts exhibits. I need a routine to stop this firefight. Which editorial habit and which style-template check at the start of drafting will prevent last-minute spacing fixes and preserve pagination?
