I have a great deal of experience with court matters, but I am now concentrating more of my time on Wills and Probate. I have been an arbitrator of Minnesota No Fault Auto Accident Claims. I graduated from Hopkins (MN) High School in 1967; St. Olaf College, Northfield MN in 1971 (BA History and Asian Studies) and William Mitchell College of Law (now Mitchell Hamline Law School) in 1975 (JD), working days and attending classes at night through a four year program. I am married and have two adult children.
A trickier question is whether you may record the other parent's conversations with the children. Under the doctrine of "vicarious consent," as long as a parent or guardian has "a good faith, objectively reasonable belief that the interception of telephone conversations is necessary for the best interests of the children," then he may consent to the interception (i.e. listening in or recording the call) on behalf of the children.  However, this can be risky, because if there is any dispute about whether your vicarious consent was in good faith or objectively reasonable, you may still end up having to defend against possible criminal charges or a civil lawsuit. The Wagner case I have cited, for example, was a civil lawsuit by a one parent against the other parent who had recorded telephone calls between the children and herself. The Court allowed that lawsuit to proceed because there was a genuine issue of material fact as to the motivations of the parent who had made the recordings. I don't recommend recording any such phone calls without first consulting a lawyer.
Most courts give parents the opportunity to work with independent evaluators soon after the case is filed to see if they can reach an agreement about custody, parenting time, money and property. The two types of ENE are: Financial ENE (FENE) to settle financial disputes and Social ENE (SENE) to settle custody and parenting time issues involving their children.
