Perjury is lying under oath regarding a material fact. If you lied on a legal document, swearing it to be true, then yes, provided what you lied about is material. If you lied about your weight or hair color and those facts are immaterial to the legal document, then it's doubtful anything will come of it. If you lied on a court record like a summons or traffic ticket, you can be charged with obstruction of justice.
