A Land Information Memorandum (LIM) can be ordered from the local council. Your lawyer can help you review a LIM which may contain information such as unconsented building works, contamination issues, flood risks, zoning (which tells you what you can do with the land) and rates. When you visit a Property, you should compare the information in the LIM with what is at the Property e.g. check to make sure the outline of the house matches the outline shown on the original plans.
