A more thorough explanation:

Definition: Recto de advocatione is a legal term that refers to a writ that restores a person's right to present a clerk to a benefice when that right had been interfered with. The term comes from Law Latin and means "of the right of advowson." This writ was abolished by St. 3 & 4 Will. 4, ch. 27.

Example: If a person had the right to present a clerk to a benefice, but someone else interfered with that right, they could use the recto de advocatione writ to restore their right. For example, if a lord of the manor had the right to present a clerk to a benefice, but the bishop interfered with that right, the lord could use the writ to restore their right.

This example illustrates how the recto de advocatione writ was used to protect a person's right to present a clerk to a benefice when that right had been interfered with.
