The hook
Sequential vs. simultaneous determines who gets the excess and who eats the deficiency when measurements don't match deeds. Sequential = senior wins. Simultaneous = everyone shares proportionally. Same starting numbers, drastically different outcomes.

Concepts that show up on the exam
Sequential conveyance
Parcels deeded over time from a parent tract. Senior (earlier) deeds get full call; junior (later) absorb any excess or deficiency.
Simultaneous conveyance
Parcels created at the same instant — a single recorded subdivision plat. All lots share excess/deficiency proportionally.
Senior rights
The earlier-recorded deed wins where it conflicts with later deeds. Order is by RECORDING date, not signing date.
Junior rights
Later parcels take whatever land remains. They benefit from excess (when bounded) and absorb deficiency.
Proportional distribution
For simultaneous: each lot gets (lot deed dimension / sum of deed dimensions) × measured total. Same fraction for everyone.

Worked example
The problem
Three lots created by an 1880 plat (simultaneous): deed widths 50, 60, 50 ft. Today's measured total = 156 ft. Compute each lot's width.

What trips people up
Calling a subdivision sequential because lots SOLD at different times
The conveyance type is determined by when the LOTS were CREATED (platted), not sold. Same plat = simultaneous, regardless of sale dates.
Forgetting original monuments outrank the math
Even with a deficiency, ORIGINAL MONUMENTS control. Find them first; apply proportional distribution only to gaps where monuments are missing.
