Injuries on the property of another have very complex issues. Some of the important issues are whether the injured person was an invited guest or trespasser. Generally speaking, some of the rules that may apply are as follows:
a. Invitee or invited licensee:
Whether, at the time and place of the incident in this case (claimant) was invited on premises owned by or in the possession of (defendant). A person is invited on land or premises of another when he enters or remains there at the invitation of the owner or possessor. An invitation may be either express or reasonably implied from the circumstances. [A person remains invited as long as [he] [she] uses the premises in the customary manner or in a manner which the owner or possessor of the premises might reasonably have expected and at a place where the visitor was invited or where [he] [she] was permitted to be or where [he] [she] might reasonably have been expected by the owner or possessor.]
b. Discovered trespasser
Whether, at the time and place of the incident in this case, (defendant) had a duty to use reasonable care for the safety of (claimant). A person who owns or has possession of land or premises who knows of a condition on the premises which involves an unreasonable risk of harm to another person on the premises has a duty to use reasonable care to warn the other person of the condition and the risk involved, if the presence of the other person is known by the owner or possessor and if the other neither knew nor should have known of the condition and risk by the use of reasonable care.
