Abstract Let be a field, H a Hopf algebra over, and R = (ᵢMⱼ) ₁ ₈, ₉ ₍ a generalized matrix algebra. In this work, we establish necessary and sufficient conditions for H to act partially on R. To achieve this, we introduce the concept of an opposite covariant pair and demonstrate that it satisfies a universal property. In the special case where H = G is the group algebra of a group G, we recover the conditions given in 7 for the existence of a unital partial action of G on R.
