Let $\mathfrak{U}$ be a $\phi$-Johnson amenable Banach algebra where $\phi \in\Delta(\mathfrak{U})$ ($\Delta(\mathfrak{U})$ is the character space of $\mathfrak{U}$). Suppose that $X$ is a Banach $\mathfrak{U}$-bimodule such that $a.x=\phi(a)x$ for all $a\in \mathfrak{U}$, $x\in X$ or $x.a=\phi(a)x$ for all $a\in \mathfrak{U}$, $x\in X$. We show that any Lie derivation (not necessarily continuous) $\delta:\mathfrak{U}\rightarrow X$ with the property that $\mathfrak{S}(\delta)\subseteq \mathcal{Z}_{\mathfrak{U}}(X)$ ($\mathfrak{S}(\delta)$ is the separating space of $\delta$) can be decomposed into the sum of a continuous derivation and a center-valued trace.
