Hi Serena - it depends how much there is and what type of sand. If it's the stuff used for making mortar, which I'm assuming it is, you'd be better removing it as best you can. It makes soil stick together, as opposed to the gritty stuff which helps open it up.
If there isn't too much, you can add organic matter - manure and compost - to help disperse it, but it would help if you could give us an idea of the volume you have
