NRS-21414 | Notices of Sale (Microfilm)

Notices of Sale (NOS) are records which detail ownership details on a land title, and are lodged at the time of a land titles transfer with Dealings. The information extracted from these forms is loaded into the Integrated Property Warehouse (IPW) database and then electronically delivered to various government agencies and rating authorities. The information that these authorities and agencies receive from the agency based on the NOS form lodged and held by LPI is essential to their key functions. Disputes or concerns raised regarding data extracted from NOS requires the agency to refer to the NOS form that was lodged and retained by the agency.Prior to the introduction of Notices of Sale, it was the solicitor's or conveyancer's responsibility to notify authorities of any ownership changes in order to effect changes in their respective record systems. The Conveyancing Legislation (Notice of Sale) Amendment Act 1992 was introduced to allow Notices of Sale to be lodged with LPI and on 1 September 1993 it became mandatory to lodge these notices with LPI. From this date, LPI was responsible for the collection, control, storage and distribution of NOS Data. The manual NOS form and its processing was introduced by LPI, and the agency started distributing information from these forms to the relevant authorities with the information being dispatched by post and later electronically. Notices of Sale were originally lodged exclusively by a paper pro forma, consisting of a completed NOS form. From April 2010, Notice of Sale were able be lodged and stored electronically, in a format known as eNOS; however, paper hardcopy NOS forms are still being used. Hardcopy NOS forms from 1996 onwards are destroyed following the storage of a digital version of the record in LPI's Document and Integrated Imaging Management System (DIIMS) database. In 2009 LPI commenced a project to digitise all of its 16mm microfilm record collection, and the microfilmed Notices of Sale from 1992-1995 are a part of what is internally referred to as the miscellaneous series". Notices of Sale are referenced by the Dealings numbering convention to which they relate. In general this reference takes the form of a number prefixed by an alpha characters; the exceptions being from 7 February 1863 to 4 December 1911 and March 1996 to 22 September 2003 were no alpha prefixes were used with the allocated numbers.

售卖通知书（Notices of Sale, NOS）是记录土地产权权属详情的文书，需在土地产权转移至交易登记环节时提交。从该类文书中提取的信息会被录入综合物业仓库（Integrated Property Warehouse, IPW）数据库，随后以电子形式分发至各类政府机构及评级主管部门。上述机构及部门从LPI留存的NOS提交文书中获取的信息，对其核心职能至关重要。若对从NOS中提取的数据存在争议或疑问，需查阅由LPI提交并留存的NOS原始文书。
在售卖通知书制度推行前，由律师或房产交割专员负责通知主管部门权属变更情况，以完成各自记录系统的更新。1992年《交割立法（售卖通知书）修正案》出台，允许将售卖通知书提交至LPI，并自1993年9月1日起，向LPI提交该类通知书成为法定要求。自此，LPI负责NOS数据的收集、管控、存储与分发。
LPI最初推出纸质制式NOS文书及相关处理流程，初期通过邮寄、后续以电子形式向主管部门分发文书信息。早期售卖通知书仅能通过纸质制式表格提交，即填写完成的NOS纸质文书。2010年4月起，售卖通知书可采用电子形式提交并存储，即电子售卖通知书（eNOS），但纸质NOS文书仍在使用。
1996年起的纸质NOS文书，在其数字版本被录入LPI的文件与综合成像管理系统（Document and Integrated Imaging Management System, DIIMS）数据库后，即可销毁纸质原件。2009年，LPI启动项目对其全部16毫米缩微胶片馆藏进行数字化处理，1992年至1995年的缩微胶片版售卖通知书属于内部所称的“杂项系列”馆藏。
售卖通知书通过其所关联的交易编号规则进行标识。通常该标识为带字母前缀的编号；但1863年2月7日至1911年12月4日，以及1996年3月至2003年9月22日这两个时间段内，分配的编号未使用字母前缀。
