v4.c63.t2.49.4

The Dharmasindhu ¹³¹⁵ also says that when a boy of another gotra is adopted after his upanayana is performed in the family of birth or when only the upanayana is performed by the adoptive father, the adopted boy should repeat both gotras at the time of bowing at the feet of elders or in śrāddha and other rites; but when all the ceremonies including the cūḍā are performed by the adoptive father then the adopted boy has only one gotra (viz. that of the adopter).
