Summary:
In this work, necessary and sufficient conditions for the oscillation of solutions of 2-dimensional linear neutral delay difference systems of the form $$ \Delta \left [\begin{matrix} x(n)+p(n)x(n-m)\\ y(n)+p(n)y(n-m) \end{matrix} \right ]= \left [\begin{matrix} a(n) & b(n) \\ c(n) & d(n) \end{matrix} \right ]\left [\begin{matrix} x(n-\alpha )\\ y(n-\beta ) \end{matrix} \right ] $$ are established, where $m>0$, $\alpha \geq 0$, $\beta \geq 0$ are integers and $a(n)$, $b(n)$, $c(n)$, $d(n)$, $p(n)$ are sequences of real numbers.
