Spanish to English Law/Patents Law (general)

Hi all,

I am translating an official letter by means of which a person is provided with copies of some legal documents he had requested. I am not sure how to translate "Resolucion de abandono y consentida", here's some context:


"Asunto: Solicita copias de la Resolucion de Abandono y Consentida

(...)

De mi consideracion:

Tengo el agrado de dirigirme a usted, en merito a la carta de la referencia mediante la cual solicita copias de la resolucion de abandono y consentida correspondientes a sus menores hijos, cuyas nuevas identidades son XXX y XXX, documentos que requiere para realizar tramites administrativos relacionados a sus pasaportes britanicos en Inglaterra, lugar donde estarian residiendo los citados niños."

Further down in the text they use the term "auto de abandono", is that the same as a "RESOLUCION de abandono"?

As you can see, it refers to the abandonment of two children, who were later adopted by a British couple.

My try is "Agreed decree of abandonment" but I'm not sure about the "consentida" bit.

Thanks in advance.
