Can i put topsoil ontop of existing lawn, and then re-lay new grass?
I bought a house off a developer who didn't put down new topsoil when laying the lawn. Do I need to rotivate it and start again or can I simply lay topsoil on top of my current lawn and then relay more turf? In addition, I have a squirrel who keeps digging holes in the grass. How do I stop it!!!

I would not lay topsoil just on top. I would prepare the yard as it should be done as to not promote root rot from the dying grass underneath. If these large clumps are broken up, and tilled in, then they pose much less of a threat, since it will decompose much faster in that fashion.
My recommendation would be starting from scratch. Another option would be to only fill in low spots, then seed, but you may get less than desirable results.
