  Let $\mathbf{k}$ be a field of arbitrary characteristic, let $\Lambda$ be a
finite dimensional $\mathbf{k}$-algebra, and let $V$ be an indecomposable
Gorenstein-projective $\Lambda$-module with finite dimension over $\mathbf{k}$.
It follows that $V$ has a well-defined versal deformation ring $R(\Lambda, V)$,
which is complete local commutative Noetherian $\mathbf{k}$-algebra with
residue field $\mathbf{k}$, and which is universal provided that the stable
endomorphism ring of $V$ is isomorphic to $\mathbf{k}$. We prove that if
$\Lambda$ is a monomial algebra without overlaps, then $R(\Lambda,V)$ is
universal and isomorphic either to $\mathbf{k}$ or to $\mathbf{k}[[t]]/(t^2)$
