Even if the trust does protect your other assets from liability associated with the land, the land itself won't be protected without insurance.
The amount of liability protection that a trust will provide depends on the type of trust, so we would need additional information in order to fully answer this question. If the trust is a Revocable Living Trust (the type of trust most commonly established and funded during your lifetime) established under NC law, then the trust provides no additional liability protection and so it would be a good idea to continue to carry the liability policy on the property.
I agree with Attorney Dalman. If the trust is a "revocable" or a "living" trust, then there is no liability protection simply because the property is in the trust. Please consult with an experienced asset protection attorney regarding other mechanisms which are available in your state to provide additional creditor protection. Good luck to you.
