If you're interested in reading some of the case law dealing with haunted houses, try this advanced search in the source "State Cases" on WestlawNext:
SY,DI(haunt! or poltergeist /p residence or home or house)
If you are not familiar with synopsis/digest searches yet, you should make them part of your research strategy when you're trying to locate relevant case law quickly and efficiently. A synopsis/digest search, or "sy/di search," searches only West Topic and Key Number descriptions, headnote text, and the synopsis text (the editorial summary that appears at the beginning of a case). Using a sy/di search can help you eliminate cases that only briefly mention the legal concepts you're searching for (like footnote references or parentheticals). You can use the advanced search menu to format your synopsis/digest search or just use the search query format shown above.
