Umbrella policy for a sold home

[Sonu Sharma]

I have an umbrella policy as an add-on to my auto policy to cover for my rentals. However, would anyone know if the same umbrella policy covers for properties once I sell them ? Asking as I heard that the buyers can sue the seller for certain issues after the sale. This happened to a person that I know who got sued for foundation issues a year after the sale although the case was withdrawn later by the buyer. I wanted to see how we could protect against such liabilities once we do not own the home.
