What is the statue of limitations for perjury?
My wife in 2006 made false statements to the police in regards to me assaulting her. I discovered she was having an affair with my then best friend. She then, under oath, lied in court about the incident and the affair. Since then she has admitted while in marital counseling with me about her lying to the courts and the police about the assault and the affair. She stated that she made the whole thing up because she was afraid of losing our kids. She has also admitted to the lies to our closest friends. I have her on CD from her phone call to me from jail on 10/08/09 admitting she lied as well.
The statute of limitations for perjury, as a Class B felony, is six years in your state. However, while you can file a criminal complaint, it will be up to the prosecutor to determine if this goes forward or not, as a criminal matter.
What might make more of a difference, for you, is how you might be able to use the recorded admission for civil purposes, or for clearing your own name.
I'd strongly recommend that before you do anything, you take the recording to an attorney, to discuss whether its contents are solid enough to use - and whether or not it was legal for you to make that recording in the first place.
