Adoption

दत्तकग्रहणम् (the classical dharmaśāstra term for formal legal adoption, discussed with specific inheritance-share rules in texts like the Dattaka Mīmāṃsā literature) is available and not wrong, but the fuller descriptive phrase is preferred here to foreground full inheritance rights without importing dharmaśāstra’s specific partial-share adoption rules, which do not match Romans’ picture of complete heirship.
