Dāyavibhāga (Inheritance Apportionment) and Household Precedence — Dialogue of Yudhiṣṭhira and Bhīṣma
पाणिग्रहणमन्त्राणां निष्ठा स्यात् सप्तमे पदे । पाणिग्रहस्य भार्या स्याद् यस्य चाद्ि: प्रदीयते । इति देयं वदन्त्यत्र त एन॑ निश्चयं विदु:
pāṇigrahaṇamantrāṇāṁ niṣṭhā syāt saptame pade | pāṇigrahasya bhāryā syād yasya cādiḥ pradīyate | iti deyaṁ vadanty atra te enaṁ niścayaṁ viduḥ |
毗湿摩说：“婚礼咒辞的约束之力，于七步礼（saptapadī）第七步方告圆满；至此夫妻之分才得确立。女子在立誓并以水为供而正式被交付于某男子时，便成为那男子之妻；唯此人是她的 pāṇigrahītā——执其手而成婚者。博学之士正是如此阐明‘施女礼’（kanyādāna）的程序，并以此为定论。”

Educational Q&A
Bhishma states a dharma-rule about marriage: the marriage mantras are considered fully effective at the seventh step of the saptapadī, and the woman is regarded as the wife of the man to whom she is ritually given with the formal resolve and water-offering—this establishes the definitive marital bond.
In Anuśāsana Parva, Bhishma is instructing Yudhiṣṭhira on dharma and proper conduct. Here he clarifies the authoritative determination of when marriage becomes binding and who is recognized as the lawful husband in the context of pāṇigraha and kanyā-dāna.
