LLINGTON, P. J., ANDREWS and RICKMAN, JJ.
ELLINGTON, PRESIDING JUDGE.
to a granted application for an interlocutory appeal, Richard
Chad McDowell contends that the Superior Court of Bryan
County erred in permitting Judith and Jeffrey Bowers, the
paternal grandparents of J. N. S., a minor child, to
intervene in his petition to adopt the child. Because Georgia
law does not permit the grandparents to intervene under the
circumstances presented in this case, we must reverse the
superior court's order allowing the intervention.
relevant, undisputed facts of this case are as follows. J. N.
S., the biological child of S. S. and E. S., was born in
2009. The child's parents divorced in 2012. The divorce
decree, which established the parents' visitation rights,
contained no provision concerning grandparent visitation. E.
S. died in an accident in 2014. In September 2014, S. S.
agreed to allow McDowell to adopt J. N. S., and the probate
court granted McDowell letters of guardianship. McDowell is
not a blood relative of J. N. S. Rather, McDowell was
previously married to S. S. They had a son in 2005; they
divorced in 2008. J. N. S. has regularly visited McDowell and
his half-brother and has reportedly formed a bond with them.
McDowell filed a petition to adopt J. N. S. on September 23,
2015. Shortly thereafter, the granparents filed their motion
to intervene, which the superior court granted. According to
their supporting brief, the grandparents are seeking custody
of the child pursuant to OCGA §§ 19-7-3 and
matters of adoption, the superior court has a very broad
discretion which will not be controlled by the appellate
courts except in cases of plain abuse." (Citation and

Ga.App. 117, 118 (640 S.E.2d 690) (2006). However, where, as
here, an appeal involves a question of law, we owe no
deference to the trial court and our review is de novo.

it is clear from the record that the grandparents believe
they can provide the best possible life for their grandchild,
Georgia law does not authorize them to intervene in this
third-party adoption proceeding to obtain custody under the
circumstances presented. Contrary to their contention,
"OCGA § 19-7-3 only authorizes grandparents to
intervene to obtain visitation rights in the
proceedings specified in the Code section." (Citation
omitted; emphasis supplied.) Murphy v. McCarthy, 201
Ga.App. 101, 102 (410 S.E.2d 198) (1991). This Code section
does not authorize intervention for the purpose asserted by
the granparents, that is, to object to the adoption and to
obtain custody themselves. Further, the only adoption proceedings
listed in this Code section are those in which the child is
being adopted by a blood relative or a stepparent, and
McDowell is neither. OCGA § 19-7-3 (b) (1) (B). See
Murphy v. McCarthy, 201 Ga.App. at 102. Finally,
because "an adoption is not the equivalent of a
proceeding to terminate parental rights within the meaning of
OCGA § 19-7-3, " id., OCGA § 19-7-3 (b) (1)
(B) provides no basis for permitting the grandparents to
OCGA § 19-8-15 governs when objections by grandparents
are allowed in adoption proceedings. Murphy v.
McCarthy, 201 Ga.App. at 102. It provides that the blood
relatives of a minor child may object to an adoption in
limited circumstances. OCGA § 19-8-15 (b) provides, in
If the child sought to be adopted has no legal father or
legal mother living, it shall be the privilege of any person
related by blood to the child to file objections to the
petition for adoption. A family member with visitation rights
to a child granted pursuant to Code Section 19-7-3 shall have
the privilege to file objections to the petition of adoption
if neither parent has any further rights to the child and if
the petition for adoption has been filed by a blood relative
of the child.
the circumstances of this case, this Code section does not
give the grandparents standing to object to the adoption. J.
N. S.'s legal mother is alive and she has consented to
the adoption. Further, by its plain terms, OCGA §
19-8-15 (b) only provides that objections may be made when a
blood relative files for adoption of the minor child, and
McDowell is a non-relative third party. Finally, the
grandparents have not established any visitation rights to J.
N. S. pursuant to OCGA § 19-7-3. Because the grandparents
have failed to show that they have a legal right to object to
the adoption, they are not authorized to intervene in this
adoption proceeding, and the order granting intervention must
be reversed. See Murphy v. McCarthy, 201 Ga.App. at
Andrews and Rickman, JJ., concur.
