What Is Simultaneous Conveyance?
Simultaneous conveyance means the lots or parcels were created together in one act, usually a subdivision plat or a single deed that cuts several lots at once. No lot is senior to another. Conflicts are resolved so the whole plan stays intact, not by awarding the overlap to the lowest lot number.

One moment, many parcels
When a owner records a plat, the lots, streets, and easements come into being together. Lot 1 does not get first pick over Lot 2. If the plat contains too little or too much distance to match every numbered dimension, the shortage or excess is handled under the rules for that kind of plat, often by honoring monuments and the plan rather than by reading the lots as a sequence of deeds. A deed that says Lot 12, Block C, according to the plat recorded in a named book and page, is a simultaneous-conveyance description. The plat is the description. You do not hunt for a senior lot unless something else was conveyed before the plat.
How this differs from selling the farm in pieces
Sequential conveyance is the other pattern: the west half deeded in May, the east half in August. The May deed is senior. People mix the patterns when a plat note says lots will be sold separately. The sales happen on different days, but the lots were created together by the plat. Seniority between lot buyers does not reopen the plat dimensions. What can be sequential is a later resubdivision, a lot-line agreement, or a deed of a strip that was never platted. Read whether the line you care about was born on the plat or in a later deed. The tax map collapses both patterns into polygons. It will not tell you which rule applies. The recording date of the plat versus the deeds is the clue.
Practical reading
Pull the plat that the deed cites, including later replats that may have replaced the lot. Check monuments the plat calls for. If two lot dimensions overlap on paper, look for a monument, a recorded correction, or a drafting error before you invent a senior lot. Do not move a fence to the dimension you prefer. A laser measure along the curb is not a survey of the plat, and a phone GPS will not apportion excess among the lots. Platbookmapper links to county GIS so you can identify the tax parcel and often the subdivision name. It does not apportion plat distances, draw lot lines, or show zip codes. A surveyor is who distributes a real excess or shortage the way the plat and the monuments require.
What to do next
- Cite the plat, book, and page as the source of the lots.
- Treat the lots as created together unless a pre-plat deed says otherwise.
- Look for replats and correction affidavits before you rank lot numbers.
- Do not use senior-deed logic on two lots from the same plat.
The mix-up to avoid
Declaring Lot 1 senior because it was sold first. The sale date is not the creation date. The plat created the lots together.
Questions people ask
What if the plat was never finished and lots were deeded by metes?
Then read those deeds. An unrecorded plan may explain names, but it may not be the conveyance. Unrecorded maps do not automatically create simultaneous lots. The recorded documents control.
Can one plat contain both patterns?
The lots on that plat are simultaneous with each other. A boundary of the parent tract may still be junior or senior to an outside neighbor whose deed is older or younger than the plat. Inside versus outside is the distinction to write down.
Find the county map
Start at Platbookmapper, search the county, and open the local GIS link. Write down the parcel number before you compare the screen to a paper plat.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
