SAPCR stands for Suit Affecting Parent-Child Relationship. Generally, a parent files a SAPCR when they want to court to order child custody, visitation or support. It is essentially a legal request and often accompanies divorce proceedings. Although it is most often filed by a parent, a SAPRC can also be filed by a legal guardian, a man claiming to be the child's father, a person with visitation rights, foster parents or even Child Protective Services.
