What constitutes interference with custody?

Interference with custody primarily involves the unlawful taking of a child from someone who has legal custody or authority over them. The correct answer highlights a situation where a child under the age of 18 is taken from a lawful custodian without the legal right or authority to do so. This act undermines the custodial rights of the individual who has legal responsibility for the child, potentially placing the child at risk and violating custodial agreements or court orders.

The other options do not describe interference with custody. For instance, removing minors from the state with a valid court order is permissible and does not constitute interference, as it is done within the parameters of the law. Documenting lawful authority to detain a child is also not an infringement on custody; rather, it demonstrates the appropriate legal framework under which a child can be taken into temporary custody. Lastly, providing legal guardianship does not interfere with custody; instead, it designates a new legal status for the child under guardianship, which is typically established through legal processes.
