We have had my fiancées daughter since the day she was released from the hospital after birth . Hes on her birth certificate . shes 3 months and we plan on getting married in the next few days . Her birth mothers Mother is trying to talk her out of it and looking into trying to take her from us , even tho her daughter said there is No way she will let her take her away from us nor will she change her mind . In seeking information on if the grandmother has any rights after the adoption and if there is a waiting period on how long we have to be married , how long ? Thank you .
