Unauthorized. Valeria and Doctor Doom worked to found his own team of Avengers during AXIS in Avengers World #15-16. It's quite unlikely they were recognized as an official extension of the roster.
Valeria Richards has a complicated history. Reed and Sue Richards's second child was originally conceived in Fantastic Four (1st series) #254. Because the child was conceived in the Negative Zone, complications arose and Sue miscarried in #267. In Fantastic Four (3rd series) #15, a teenaged girl named Valeria von Doom debuted, claiming to be the future daughter of Sue and Victor von Doom. In #49, it was revealed Valeria was actually Sue and Reed's second child, saved and transplanted into a future timeline by Franklin's reality-altering powers. After the confrontation with Abraxas, Valeria von Doom's existence was negated and Sue's pregnancy was restored to the third trimester. Valeria Richards was then delivered by Doctor Doom in #54.
