Withdrawal of any consent or relinquishment is not permitted except by order of the court after notice and opportunity to be heard is given to all persons concerned, and except when the court finds that the withdrawal is in the best interests of the child and that the consent or relinquishment was not given voluntarily or was obtained under duress or through coercion. Any person attempting to withdraw consent or relinquishment shall file the reasons for withdrawal with the family court. The entry of the final decree of adoption renders any consent or relinquishment irrevocable.

SECTION 20-7-1720 did not apply to a purported consent to adoption signed by the natural father, who, in reserving the right of visitation, did not agree to relinquish all rights to the child within the meaning of SECTION 20-7-1770(b). McLaughlin v. Strickland (S.C.App. 1983) 279 S.C. 513, 309 S.E.2d 787.

2. Under former law

Consent to adopt not technically "filed" prior to requested withdrawal, but filed and part of record when matter was heard by master, gave court discretion to accept or reject attempted withdrawal of consent and to find that it would be in best interest of child for adoption to be finalized. Ellison v. Camby (S.C. 1977) 269 S.C. 48, 236 S.E.2d 197.

Master's findings that statutory filing requirements had been sufficiently met where consent to adopt was not filed until 1 day after requested withdrawal of consent and therefore permitted court to accept or reject attempted withdrawal were well within scope of discretion statutorily granted to him; findings had evidentiary support in record and were not against preponderance of evidence. Ellison v. Camby (S.C. 1977) 269 S.C. 48, 236 S.E.2d 197.

When, in adoption proceedings, the natural parents withdrew their consent, and the petitioners joined in with the withdrawal of consent and withdrew their petition for adoption, the children's court of Spartanburg County lost jurisdiction, notwithstanding the provision of Section 15-1391 that when once the children's court obtains jurisdiction, such jurisdiction continues during the minority of the child. Driggers v. Jolley (S.C. 1951) 219 S.C. 31, 64 S.E.2d 19.
