1. A judgment in a habeas corpus proceeding instituted by parents to secure the custody of their minor children is conclusive upon them unless a material change of circumstances affecting the welfare of the children is made to appear. In the instant suit by a father against a mother for the writ of habeas corpus to obtain the custody of minor children awarded to him by a previous judgment in such a proceeding between him and the mother, the judge was authorized to find that the evidence produced upon the hearing showed such a material change of circumstances substantially affecting the welfare and best interest of the children as would render the first judgment inconclusive on the parties.
(a) The evidence authorized the judge, in the exercise of a sound discretion, to award the custody of the children to the mother.
In a habeas corpus proceeding involving a contest between parents over the custody of minor children, the paramount issue is the welfare and best interest of the children, and an award *Page 59 made by the judge, based upon the evidence and in the exercise of a sound discretion, will not be controlled by this court. Code, §§ 50-121, 74-106, 74-107; Lamar v. Harris, 117 Ga. 993 (44 S.E. 866); Willingham v. Willingham, 192 Ga. 405 (15 S.E.2d 514); Attaway v. Attaway, 194 Ga. 448 (22 S.E.2d 50). Such a judgment is conclusive between the parties, and the principle of res judicata is applicable unless a material change of circumstances substantially affecting the welfare and best interest of the children is made to appear. Barlow v. Barlow,141 Ga. 535 (81 S.E. 433, 52 L.R.A. (N.S.) 683); Jordan v. Jordan, 195 Ga. 771 (1) (25 S.E.2d 500). A change of circumstances that would render a prior judgment inconclusive is not necessarily limited to a change in the moral or financial condition of the parent to whom the initial award was made, but includes any new and material change in the circumstances of either parent or of the children, which might substantially affect the health, happiness, or welfare of the children. "While judgments in habeas corpus proceedings instituted by parents to secure the custody of their minor children are conclusive upon them, such conclusiveness relates to the status existing at the time of the rendition of such judgments. Change of status may authorize a different judgment in a subsequent proceeding. . . The capacity, ability, or fitness of the party to whom the child was awarded in the previous proceeding may thereafter become entirely different. The status of both such parties and the child may have changed. Change of circumstances may render a change necessary in order to promote the health, happiness or welfare of the child. Williams v. Crosby, 118 Ga. 296 (45 S.E. 282)."Lockhart v. Lockhart, 173 Ga. 846 (162 S.E. 129). See alsoKirkland v. Canty, 122 Ga. 261 (50 S.E. 90); Sells v.Sells, 172 Ga. 911 (159 S.E. 237); Milner v. Gatlin,143 Ga. 816 (85 S.E. 1045, L.R.A. 1916B, 977).
In the present case, the evidence was amply sufficient to show such a material change in circumstances substantially affecting the welfare and best interest of the minor children as would render the judgment awarding the custody of the children to the father in the initial habeas corpus proceeding inconclusive on the parties, and the judge did not abuse his discretion in awarding custody of the children to the mother. *Page 60 Judgment affirmed.
