The Overlapping Aliquot in a Section with a Meander Line
You are retracing Section 14, T12N, R3W, Seward Meridian. The 1887 GLO plat shows the north half of the NE1/4 as 80.00 acres, but a modern closing of the original corners gives the NE1/4 a total area of 165.4 acres. The east boundary of the NE1/4 is a meander line along a navigable river; the plat shows the meander line with three meander corners and the river as the boundary. A 2023 survey by another firm set a new monument at the position they computed for the E1/4 corner of Section 14, placing it 41.2 ft west of the position implied by the original 1887 bearing trees, which are still standing and sound. The adjoining owner has built a fence to that 2023 monument. Your client holds the north half of the NE1/4 by a deed describing 'the N1/2 of the NE1/4' with no acreage stated.
1. How do you treat the 2023 monument and the original bearing trees in re-establishing the E1/4 corner, and what controls the location of that corner?
Read the worked answer
The original 1887 bearing trees are the best available evidence of the original corner position. Under the hierarchy of evidence, original monuments and their accessories control over subsequently set monuments, and over measurements. The 2023 monument is a non-original monument set by a later surveyor; it carries weight only as evidence of that surveyor's opinion, not as control. Because the bearing trees are sound and identifiable, you re-establish the E1/4 corner at the position they indicate (using the recorded bearing and distance from the trees, checking against the plat's ties), and you treat the 41.2 ft discrepancy as a measurement error in the 2023 survey, not as a movement of the corner. You should document the bearing-tree evidence, the 2023 monument, and the discrepancy, and note that the fence built to the 2023 monument does not move the boundary; occupation to a mistakenly set monument does not, by itself, transfer title where the true corner is provable.
2. The NE1/4 closes at 165.4 acres rather than 160. How do you apportion the excess (or deficiency) between the north and south halves, and does the meander line change the answer?
Read the worked answer
First, confirm the 165.4-acre figure is the result of a proper closing on the original corners and that the excess is real, not a computational artifact. For a subdivision of an aliquot part into halves, excess or deficiency is apportioned proportionally to the plat acreage of each part, because the original survey created the halves as equal-area aliquot parts. The N1/2 and S1/2 each take half of the excess: each is entitled to 82.7 acres of area, and the division line is located so as to produce that result, measured from the controlling corners. The meander line does not change this: the meander line is not a boundary; the river is. The area shown on the plat beyond the meander line is not part of the aliquot subdivision for apportionment purposes, and accretion or reliction along the river is a separate question governed by the rules for navigable water boundaries. Do not use the meander line as a basis for shifting the half-section line.
3. The client asks whether the 2023 fence line has become the boundary by acquiescence or adverse possession. What is your analysis?
Read the worked answer
Acquiescence requires that the adjoining owners treat a line as the boundary, typically for the statutory period, with the mistaken belief that it is the true line, and that the true boundary is uncertain or unascertainable. Here the true corner is provable from original bearing trees, so the boundary is not uncertain; a fence built to a monument set in error is weak acquiescence evidence. Adverse possession in Alaska requires, among other elements, actual, open, notorious, exclusive, hostile, and continuous possession for the statutory period (AS 09.10.030, 10 years), and payment of taxes is a statutory condition for a claim of title by adverse possession. A fence alone, without the required possession and tax payment, does not ripen into title. Advise the client that the record boundary controls, that the fence is a trespass to the extent it crosses the true line, and that the client should not rely on the fence as a boundary; document the original evidence and consider a boundary line agreement or quiet title action if the neighbor disputes it.
