  Let $G_{\mathbb{Q}_p}$ be the absolute Galois group of $\mathbb{Q}_p$ and let
$L$ be a finite extension of $\mathbb{Q}_p$. Moreover let
$\bar\rho:G_{\mathbb{Q}_p}\rightarrow GL_n(k_L)$ be a continous representation
of $G_{\mathbb{Q}_p}$, where $k_L$ is the residue field of $L$ and $n$ is a
natural number greater than $1$. We find sufficient conditions for which a
trianguline representation $\rho:G_{\mathbb{Q}_p}\rightarrow GL_n(L)$ lifting
$\bar\rho$ is a point of the trianguline variety associated to $\bar\rho$.
