N.J.S.A. 9:17-43(a)(1) establishes a presumption that "[a] man is presumed to be the biological father of a child if . . . [h]e and the child's biological mother [were] married to each other and the child [was] born during the marriage." The decedent here died intestate, leaving siblings and a child, who was born when his mother was married to another man. Decedent's siblings claim this presumption, as well as other circumstances, required the court to assume that the mother's husband had "equitably adopted" the child and thereby severed the child's relationship to the decedent. The court affirmed the trial court's grant of summary judgment, holding that N.J.S.A. 9:17-43(a)(1)'s presumption had been rebutted by DNA evidence that conclusively established that the decedent fathered the child, and that the other circumstances were of insufficient weight to cause a break in that natural relationship.
