It is the state’s policy to ensure the child’s welfare when granting custody (Fam. C. § 3020), and it is safe to assume that the court issues “an order for the custody of a child during minority that seems necessary or proper” (Fam. C. § 3022). Therefore, when the court grants custody to one parent, the court has already decided based on the circumstances surrounding the child and the custodial parent (or nonparent), and determined according to the child’s best interest based on Fam. C. § 3040 et seq.
For issues involving custody and child welfare, it is best to contact an attorney who is an expert in family law for more information and proper guidance.
