Hi,
The adoption will be done through court proceedings, so you will need a lawyer to represent you. There are documentary requirements for the filing of the adoption. Since your daughter is an illegitimate child, both you and your husband must adopt your daughter. Once approved by the court, the rights of your child will be similar to that of a legitimate child. Thus, when you and your husband have children in the future, they and your daughter will have the same right to support, use the surname of your husband and right to inheritance with respect to you and your husband.
Since the father of your daughter is willing to give his consent to the adoption, it should a straightforward process.
If you need legal representation, you may email km@kgmlegal.ph
