accessory before the fact

In one sentence

Helping someone plan or prepare to commit a crime before it happens.

Plain English

An accessory before the fact is someone who helps another person plan, prepare for, or encourage a crime, but isn't present when the crime actually happens. For example, you might help someone plan a robbery, give them tools, or provide information—but you're not there when they do it. You're still criminally liable because you intentionally helped make the crime possible.
