If you bought a piece of property and house and a few years later your told that your front lot and driveway is on the old owners poperty is this negligent misrepresentation on their part?

Yes, this situation could potentially be classified as negligent misrepresentation if the previous owner knowingly provided false information about property boundaries, or failed to disclose relevant facts that they should have been aware of. If the owner had a duty to inform you of the property lines and did not do so, leading you to believe that the lot and driveway were part of your property, you may have grounds for a claim. However, the specific circumstances and applicable laws in your jurisdiction will ultimately determine the outcome. Consulting with a legal professional would be advisable to explore your options.
