Definition - What does Common Counts mean?
Common counts are a type of common law pleading. These pleadings are used when a party believes that another party owes him or her money, but no formal contract was exchanged between the two parties. Instead, there was an oral agreement between the two parties to exchange money for services rendered.
Justipedia explains Common Counts
Common counts are a more traditional type of pleading. They are no longer used, and have been replaced by complaints. A situation where a common count pleading may have been used would be if a man was promised to be paid $1,000 for building a fence for another man, and the man who promised to pay never actually did. So, in essence, common counts are pleadings where a party is trying to recover a debt that is owed to them.
