In Scots law, tailzie (/ˈteɪli/) is a feudal concept of the inheritance of immovable property according to an arbitrary course that has been laid out, such as in a document known as a "deed of tailzie".
Other spellings of the word are tailie, taillie, tailze, tailyie, tailye, taylzie, teally, teilzie, telyie, teylyie tyle, talyee.
It is derived from the Old French tailler 'to cut' and taille 'cutting'.
The 'z' was, until the simplification of printing to 26 characters, a yogh (tailȝie) and so is not sounded.
[4][not specific enough to verify] The Entail Amendment Act 1848 gave all heirs in tailzie power to apply to the Court of Session to cease the deed of tailzie, compensate respective claims, thus take estate possession in fee simple.
