UNDERSTANDING LEGAL LAND DESCRIPTIONS - IT'S EASY!
The United States uses
several different methods of describing a unique parcel of land. Generally speaking,
the Eastern United States uses the METES AND BOUNDS system, while the Western
United States uses the RECTANGULAR SURVEY method. This is because the Eastern
United States was settled before the rectangular survey method was designed.
This is also true of Canada with a few added quirks. There are some exceptions
to this rule, the most important one being certain parts of Texas, which will
be discussed later. We will learn the rectangular survey method first because
it is the easiest.
In the following example we are going to be locating an 80 acre parcel of land.
This land is described as:
Township 2 South, Range 2 East, 6th PM
Section 31: S1/2 SW1/4
This method is based on a measurement from a particular Meridian and degree
of latitude, called a baseline. Each meridian has a matching baseline, so the
baseline is never referred to in legal descriptions. For example, most of Colorado
and Wyoming are measured off of the 6th Principal Meridian (abbreviated 6th
PM). This meridian is not even in Colorado, but rather runs north and south
through Kansas or Missouri (I can't remember exactly where the 6th PM is and
it isn't important anyway). Parts of Illinois are measured off of the 5th PM.
Montana is measured off of the Montana Principal Meridian (MPM). Parts of California
and Nevada are measure off of the Mount Diablo Prime Meridian (MDPM). Meridians
and baselines aren't that important to you in general because they are understood
and often aren't mentioned in an old legal description. Some states, such as
Colorado, have rectangular surveys based off of more than one meridian. Colorado
has a small area in the southwest that is measured off of the Ute Meridian.
This is because the Ute Indian Reservation was surveyed at a later date and
the surveyors used a different meridian. The most important thing for you to
know here is that Meridians are lines running North-South (with parcels of land
being measured as East or West of the Meridian) and baselines run East-West
(with parcels of land being measured as North or South).
The goal here is to narrow down a description to a smaller and smaller area.
The Rectangular Survey uses something called a Township to do this. A Township
is a square parcel of land 6 miles long on each side. If we do the math, we
determine that it contains 36 square miles (6x6=36). Townships are numbered
as being North or South of the baseline and East or West of the Meridian. Once
you have determined your Township, you have your lands narrowed down to 36 square
miles. Look at the example below.
First you locate your Township by going 2 squares east of the Prime Meridian
and 2 squares south of the baseline. The pink parcel is the target. After you
have found your Township, you need to narrow it down further. Notice the blowup
of the pink Township. A Township is divided into 36 Sections which are 1 mile
square each. Numbering begins with Section 1 in the upper right corner and winds
back and forth until it finally ends up with Section 36 in the lower right hand
corner. In this exercise we were given Section 31 to locate, which is in the
lower left hand corner. Section 31 is blown up and shown in green below.
Now we have narrowed our search down to 1 square mile of land which contains
640 acres. When we describe subdivisions of a Section, we describe them in halves
or quarters such as the East half of Section 31, which is usually written:
Township 2 South, Range 2 East, 6th PM
Section 31: E1/2
or
E1/2 of Section 31, Township 2 South, Range 2 East, 6th PM.
We know that the E1/2 of Section 31 contains 320 acres, because it is half
of a full Section. We can also describe smaller parcels of land such as the
Southwest quarter of Section 31. This would be abbreviated Section 31: SW1/4
and would contain 160 acres, which is ¼ of 640 acres. Now it gets trickier as
we describe smaller parcels of land. You have to read them backwards to locate
your piece.
Consider the following examples:
Section 31: E1/2SE1/4
This is read as the East half OF the Southeast quarter. First you locate
the Southeast quarter of Section 31, which contains 160 acres. Then you divide
that piece into halves and locate the East piece, which will contain 80 acres.
Section 31: SE1/4NW1/4
Read this as the Southeast quarter OF the Northwest quarter. Find the Northwest
quarter and then divide it into quarters. The Southeastern quarter is your target
and contains 40 acres.
NOW A WORD ABOUT COMMAS - THEY ARE IMPORTANT!
Commas separate different parcels of land and when you see one, substitute
the word AND for the comma.
Consider the following 2 similar descriptions:
Section 31: S1/2NE1/4
Section 31: S1/2, NE1/4
They are the same, except for the comma! The first parcel contains 80 acres
and the second parcel contains 480 acres - a big difference!
The first parcel reads "the South half OF the Northeast quarter"
The second parcel reads "the South half AND the Northeast quarter"
One final note on the Rectangular Survey. Although most Sections contain
640 acres, this is not always so. Corrections were made by the surveyors because
the earth is curved. The top tier of Sections in a Township will always be smaller
than the bottom tier because of this curvature. Corrections were made along
the top tier and along the western column of sections in a Township. Sometimes
you will see these corrections referred to as Lots with the acreage indicated
in parethensis, such as:
Section 31: Lot 1 (38.06), S1/2NE1/4
If this had been a normal Section, Lot 1 would have been the NE1/4NE1/4
and would have contained the usual 40 acres. You will also often find Lots when
a river meanders through a Section. If you need to know exactly where the Lots
are, you can order an MT plat (master title plat) from the Bureau
of Land Management that handles your state for about $2.00. Just give
them the Township and Range and they will send you the plat for the entire township.
