What is the name of your state (only U.S. law)? Delaware
What Title and Chapter of the Delaware Code is perjury/false swearing in Court testimony or documents?
Just an FYI...
Perjury is a crime that must be prosecuted by the DA in order to go anywhere.
I have yet to see a DA, anywhere, being willing to prosecute someone for lying in a divorce or child custody case.
I have seen people try to push through a perjury case in very extreme circumstances (family law) without being able to convince a DA to even consider the case.
