HIPAA Authorization Form for Parents

If the child has a single parent, then the form only requires the signature of that parent. If the child is under joint custody, both parents must sign the form.

Yes. Parents or guardians can choose to revoke the form. They can do so using the same form if it has a revocation clause or through a separate form for revocation. Do note that once it has been revoked, formerly authorized individuals will no longer have access to the child’s medical information.

That depends on the clause on the form. Some forms are only for one-time use. Some are valid until the parents revoke the access rights or the child becomes an adult.
