Case Date Legal Subject Abstract
Ritchie v. Patersons 1794 Succession, Aliment, Interlocutor, Liferent, Debt, Jus Relictæ Agnes Ritchie pursued the Patersons for one-fifth of her grandfather John Paterson’s moveable estate under his settlement, seeking to claim the share notwithstanding her mother’s predecease. The defenders maintained that she was entitled only to one-fifth of the dead’s part of the estate rather than one-fifth of the whole personal estate.
Ross, et al. v. Aglianby 1796 Debt, Terce, Jus Relictæ, Deed, Succession, Interlocutor Ross and others pursued Aglianby in a dispute over estate distribution involving competing claims to terce and conventional provisions. Mrs Lowthian challenged an interlocutor voiding her conventional provisions and sought to retain funds and claim terce from her late husband's estate, prompting the respondents to answer regarding the exclusion of terce and the effect of obligations to George Mackenzie's trustees. Mrs Sarah Aglianby subsequently petitioned the court to alter its recent interlocutor respecting her own claim to terce from her husband's Scottish lands.
