Short answer, do not sign anything before review by your attorney. There is a vast difference between custodial rights and parental rights.
Kentucky law regarding custody and parenting time has officially been modified effective April 26, 2018. This applies to both wed and unwed parents.
If a divorce or custody client asks about holiday v. vacation v. weekends v. regular parenting time, there is an order to parenting time with the children which is generally spelled out in any custody order or parenting plan.
