Under the Advisory Guidelines, the difference between the gross or Guidelines incomes of the spouses, which forms the basis for the percentage division under the "without child support" formula. (See also Guidelines income.)
The legislature occasionally skips outline levels.
For example:
(3) A person may apply [...]
(4)(a) A person petitioning for relief [...]
In this example, (3), (4),
and (4)(a) are all outline levels, but
(4) was
omitted by its authors. It's only implied. This presents an
interesting challenge when laying out the text. We've
decided to display a blank section with this note, in order
to aide readability.
