In order thereto, the consent of both parents if living and not divorced or separated, and if divorced or separated, or, if unmarried, the consent of the parent lawfully having the care and providing for the wants of the child, or if either parent is dead, then the consent of the survivor, or if both parents be dead, or the child shall have been and remain abandoned by them, then the consent of the mayor of the city where the child is living, or if not in a city, then the clerk of the district court of the county where the child is living, shall be given to such adoption, by an instrument in writing signed by the parties or party consenting, and stating the names of the parents, if known, the name of the child, if known, the name of the person adopting such child, and the residence of all, if known, and declaring the name by which such child is hereafter to be called and known, and stating also that such child is to be given to the person adopting, for the purpose of adoption as his own child. [§3499] [Sidenote: Instrument acknowledged and recorded.] Such instrument in writing shall be also signed by the person adopting and shall be acknowledged by all parties thereto in the same manner as deeds affecting real estate are required to be acknowledged; and shall be recorded in the recorder's office in the county where the person adopting resides, and shall be indexed with the name of the parents by adoption as grantors and the child as grantee, in its original name if stated in the instrument, [§3500.] A strict compliance in every particular with the provisions of the statutes is essential to constitute a legal adoption and to confer upon the adopted child rights of inheritance. If a minor child has a guardian his consent must be obtained before the child can be legally adopted. [Sidenote: Effect.] Upon the execution, acknowledgment and filing for record of such instrument, the rights, duties and relations between the parent and child by adoption, shall, thereafter, in all respects, including the right of inheritance, be the same that exists by law between parent and child by lawful birth. [§3501]. The right of a child by adoption to inherit from the parents by adoption, depends upon a strict compliance with the requirements of the law in every particular, including the acknowledgment and recording of the articles of adoption. It is also essential that the instrument shall be filed for record before the death of the adopted parent and while the child is a minor. A child by adoption does not lose the right to inherit from his natural parents, but is entitled to all rights of inheritance from both natural and adopted parents. [Sidenote: Maltreatment.]
