Yes, adoption establishes all rights and duties to parents as if the parents were the biological parents of the child.  An adopted child can inherit property from his new parents, receive care from them, and becomes a loved and cared for child, just like a biological child. 

A person may adopt a child if the court finds it in the child best interest.  If persons are married, both husband and wife must join in the adoption.  A person does not have to be married to adopt a child.  

A stepparent may adopt a child if- the  child is at least 2 years old; the  parent-child relationship has been terminated with the other parent; and the step-parent has had possession of the child for at least 6 months (if the other parent consents to adoption) or at least 12 months (if the other parent doesn’t consent to adoption).

A parent may have their rights terminated if the court determines it is in the best interest of the child for that parent to have their rights terminated.  The court must also determine that the father has either abandoned the child, was imprisoned for greater than 2 years, neglected the child, abused the child, failed to pay child support for greater than 1 year, uses drugs, or is mentally ill.

A child over 12 must give his consent to be adopted unless the court finds it in his best interest.

It all depends upon the circumstances.  Some adoptions take place within a short period of time while others can take over a year.  

You do not have to have a lawyer, but it is highly recommended that individuals seeking to adopt a child hire a lawyer to assist them with the process.  Without the right guidance, adoption can be a difficult and often frightening process.  With a lawyer by your side it is often a much more enjoyable and fruitful experience for you and your new family.
