I imagine we should post complete statements, however, this is really giving me great difficulty and I cannot translate or convey meaning as I don't quite understand or find the thought clear.
known by me to be the individuals who signed the foregoing SPECIAL POWER OF ATTORNEY AND AUTHORIZATION FOR MEDICAL TREATMENT, and each of them acknowledged that document of her or her free and voluntary act and deed, for the uses and purposes therein mentioned. I certify that I have examined documents, witnesses, or other evidence, and satisfied myself that the persons signing above are the true and lawful parents or legal guardians of named CHILD.
My Attempt:
Y quien según me conocimiento me consta que son las personas que firmaron el anterior PODER Y AUTORIZACION ESPECIAL para TRATAMIENTO Y Atención médica, y cada uno de ellos reconoció el documento de ella o a su acto libre y voluntario de firmar la escritura, para el uso y propósitos aquí mencionados. Certifico que he examinado los documentos, testigos u otras pruebas, y estoy satisfecho que las personas que firmaron anteriormente, son los verdaderos y legítimos padres o tutores legales de dicho NIÑO.
Your help is greatly appreciated.
