for use by state legislatures. This was followed by publication of the Standard City Planning Enabling Act (SCPEA) in 1928. The SCPEA covered six subjects: (1) the organization and power of planning commissions, which was directed to prepare and adopt a master plan; (2) the content of the master plan; (3) provisions for a master street plan; (4) provisions for approval of all public improvements by the planning commission; (5) control of private subdivision of land; and (6) provisions for the creation of regional planning commissions.

Definition
The SCPEA included the following definition:
- "'Subdivision' means the division of a lot, tract, or parcel of land into two or more lots, plats, sites, or other divisions of land for the purpose, whether immediate or future, of sale or of building development. It includes resubdivision and, when appropriate to the context, relates to the process of subdividing or to the land or territory subdivided."
Attached to this definition was the following footnote:
- "for the purpose of sale or of building development: Every division of a piece of land into two or more lots, parcels or parts is, of course, a subdivision. The intention is to cover all subdivision of land where the immediate or ultimate purpose is that of selling the lots or building on them. The object of inserting a definition in the text of the act is to avoid the inclusion, within the planning commission's control, of such cases as a testator
A testator is a person who has written and executed a last will and testament that is in effect at the time of his/her death. It is any "person who makes a will."-Related terms:...
's dividing his property amongst his children, partners' dividing firm property amongst themselves on dissolution, or cases of that nature."

This definition, and its clarifying footnote, serves to underscore some important points about the legal nature of subdivisions. Importantly, a subdivision does not need to be sold, in whole or in part, for its resulting pieces to be considered separate parcels of land. A subdivision

approved by a local planning commission, once recorded in a registry of deeds, is generally deemed to have created the parcels of land identified on the plat itself.
The problem of testamentary division of property was identified by the SCPEA in the footnote to the definition of subdivision, but not fully clarified by it. In some jurisdictions, a testamentary division of property does not constitute a legal subdivision for purposes of separate conveyancing of the "subdivided" parcels.
Similarly difficult is the notion of "building development" in the definition, and whether the identification of multiple construction sites on a single parcel of land constitutes a subdivision subject to the review and approval authority of the planning commission. Interpretations of this vary among American jurisdictions. Subdivision developers may use an architect's services only once, with the rest of the

In the Philippines, subdivisions are areas of land that have been subdivided into individual residential plots. Whereas some subdivisions comprise exclusive gated communities, others are merely demarcations denoting a specific neighborhood. Some subdivisions may conduct autonomous security, or provide basic services such as water and refuse management. Most subdivisions are governed by associations made up of members who are residents of the subdivision. In the Philippines, subdivisions are also known as
villages.

, subdivision is the dividing of a single parcel of land into two or more parcels, each to be given a separate title. Subdivision is also used for existing lot line adjustments. Notwithstanding a few exceptional circumstances, subdivision approval and endorsement by the local municipality must always be received before the subdivision can be registered at the Land Titles Office and titles issued (including bare land condominiums). Exceptions may occur with parcels of land that contain more than one quarter section, a river lot, a lake lot, or some settlement lots created prior to July 1, 1950.
