The Rule against Hearsay and its Exceptions
You’ve probably heard of the rule against hearsay, sometimes called popularly “he said, she said.”
What hearsay actually is is an out of court statement offered for the truth of the thing said. In other words, if I testify “he shouted that she was a liar,” the evidence can’t be used as proof that she was a liar. But it can be proof that he shouted (I witnessed that) or that he SAID she was a liar (for purposes of her claim of slander, for example – I witnessed that, too).
In debt litigation, this comes up with business records, which are, after all, things that were written (statements) out of court and offered for the truth of what they say.
Your case will probably depend on applying the rule against hearsay to these documents. There are actually many exceptions, but none will be more important than the business records exception. You must know the hearsay rule and the business records exception in your jurisdiction.
