I am moving 40 miles away from non-custodial parent to secure better employment opportunity. I planned on giving non-custodia parent a 10 day notice along with kids new school info. I mailed 1 letter certified mail, but the non-custodial parent refused it. Thinking about delivery confirmation this time. is there a certain number of days I need to notify the non-custodial parent by? The parenting agreement only mentions moving out of state issues and moving more than 150 miles away. none of that applies to my situation.
