There are two misconceptions I've noticed about partition lines of a field or charge (aka lines of division).
One misconception concerns "overall". It must not be used for a charge over a partition line. From the Glossary of Terms (the version with the May, 1996, LoAR):
Overall - A term applied to charges that cross over both edges of another charge to lie on the field on either side.
Note that this is a charge partially overlying a charge. A partition line is not a charge. Therefore, "Per pale indented gules and Or, overall a fess sable" is an incorrect blazon -- the word "overall" will be removed.
Another misconception is thinking that lines of division are counted in the "rule of thumb" complexity count, RfS VIII.1.a. A fuller explanation is in another article. Basically, that rule has the total of the number of tinctures plus the number of types of charges in a design should not exceed eight.
Note that lines of partition are not in that count.
