Quick answer
Specific exchange arrangements can reduce conflict and protect children from adult disputes.
Do now
Identify recurring problems with timing, location, transportation, or communication. Ask about neutral locations, staggered exchanges, third-party assistance, or supervised services where appropriate. Put any proposed change through the proper agreement or court process.
Watch for
A police station is not automatically a staffed supervised-visitation service. A protection order may prohibit contact even at an exchange; arrange compliant terms through the court.
