What legal action can be taken on the neighbor for using my parking

I have a corner house. One of My neighbour parks his one car on one side of my house and the other one on his front side Which is opposite to my gate and obstructs my entry. I have neighbor cars but we are able to park only one car on corner side of my house as he keeps on parking his car on my side and moreover i am not able to park my car inside my house as Gate entry is also obstructed by his second car. We have been asking him to stop parking on corner side wall of our home but he is not bothering. this causes lot of inconvenience. pls suggest a remedy or any legal recourse?
