If you're out of the light cone. :x
Hard to explain. Try wikipedia if this doesn't work.
When you drop a stone in a pool of water, ripples form and move away. Same happens with a Black Hole. If you graph where that 'ripple' is with space on X and time on Y, it turns into a cone, where the point is the place and time of the black hole's creation.
If you stand out of that cone, you won't be affected by it's gravity, until you move into it as time passes. :x
