My question involves a child custody case from the State of: MN
I have sole physical custody and joint legal custody The divorce was final in 2009. The divorce decree states that my ex has parenting time each week Thursday 5 PM - Saturday 5 PM.
Last spring he agreed via email that we could change to every other Friday after school - Sunday 3 PM and every other Friday after school - Saturday 6 PM.
I re-confirmed that parenting time agreement with him in August and he agreed to continue it for the new school year for 2013-14.
Now he is asking to change back to Thursdays and keep the every other Saturday overnight. I have not agreed to this. The kids have been very happy with the current schedule of him picking them up on Fridays, as it interferes less with the school week.
He has told me that he is now going to pick the kids up on Thursday even though I have not agreed. Do I have any way to stop him from getting them on Thursday? Our divorce decree does say Thursdays, but we had an agreement through email on Friday pick up instead and I have not agreed to change that. Our divorce decree does say, "Unless otherwise agreed by the parties" in regards to the parenting time schedule. Is the email agreement for Friday pick up binding?
