Dāya-Tattva
The Dāya-Tattva is a Hindu law treatise written by Raghunandana regarding the proper procedure for inheritance following the death of the father. It is considered by many to be a follow up text to Jīmūtavāhana's digest, the Dāyabhāga. Raghunandana is considered to be a "disciple" of Jīmūtavāhana, and his texts subsequently differ only slightly from the Dāyabhāga.
