The Nevada M-4 Motion for Change of Custody or Visitation is a legal document used by a parent in Nevada to request a change of child custody or visitation rights. The motion must be filed in the court where the current child custody and visitation order was issued. The motion can request a full or partial change in custody or visitation rights. There are two types of Nevada M-4 Motion for Change of Custody or Visitation: 1) Motion for Modification of Custody: This type of motion is used to request a modification of an existing custody order. This type of motion may be used if the custodial parent wishes to request a change in the custody arrangement or if a noncustodial parent wishes to request a change in the visitation rights. 2) Motion for Emergency Change of Custody: This type of motion is used to request an emergency change in child custody due to an immediate danger to the child. This type of motion is typically used when the child’s safety is at risk due to abuse, neglect, or abandonment.
