The Law Code of Devala 6.4: Smṛticandrikā · Nirṇayasindhu · Śrāddhacandrikā (Divākarabhaṭṭa) +1

6.4

śrāddhaṃ kṛtvā tu yo vipro na bhuṅkte ca kathaṃcana | devā havyaṃ na gṛhṇanti kavyāni pitaras tathā

At a death or a birth, for female slaves, / and for wives taken in natural order of castes, / purification is equal to that of the master; when the master dies, it is by uterine kinship.

If a Brahmin who has performed a śrāddha does not eat of it at all, the gods do not accept the offerings, nor the ancestors theirs.
