8.2 Senior Rights vs. Junior Rights in Overlapping Conveyances

The Doctrine of Senior Rights

When a single tract of real estate is subdivided and conveyed over time through a series of private deeds, the legal relationships between adjoining parcels are governed by the Senior Rights Doctrine. In Mississippi property jurisprudence, seniority of title is rooted in one of the most fundamental maxims of Anglo-American property law:

$$\textbf{"Nemo dat quod non habet"} \quad \text{— } \textit{No one can give that which they do not possess.}$$

When an owner of an unencumbered parent tract (the Common Grantor) executes a deed conveying a portion of that land to a purchaser, title to the described property passes to the grantee on delivery of the deed, and recording protects it against later purchasers (§ 89-5-1). That first conveyance out creates a Senior Deed. The land retained by the grantor constitutes the Remainder (or Residue).

If the common grantor subsequently executes a second deed conveying another parcel from the remainder, this subsequent instrument is a Junior Deed. The grantor can convey to the junior purchaser only that land and those rights which the grantor still owns at the moment of execution. If the junior deed contains a legal description whose physical boundaries overlap the land previously conveyed to the senior grantee, the senior title prevails, and the junior deed is legally void to the extent of the overlap.

Overlaps and Gores: Causes, Legal Status & Resolution

Discrepancies in boundary descriptions between adjoiners commonly manifest in two distinct geometric forms: Overlaps and Gores (often called Gaps).

The Anatomy of an Overlap

Consider the classic scenario illustrated above:

1. A common grantor owns a parcel recorded as 1,000.00 feet wide east-to-west.
2. In 1980, the grantor conveys "the West 600.00 feet" to Smith (Senior).
3. In 1995, the grantor conveys "the East 500.00 feet" to Jones (Junior).
4. When a boundary survey is conducted, the surveyor measures the total parent tract width and finds it measures exactly 1,000.00 feet on the ground.
5. Adding the two descriptions: $600.00\text{ ft} + 500.00\text{ ft} = 1,100.00\text{ ft}$. There is an overlap of 100.00 feet.
6. Result: Smith owns the entire West 600.00 feet. Jones receives title to only the East 400.00 feet. The fact that Jones's deed calls for 500.00 feet is legally irrelevant to Smith's property rights because Smith's senior deed exhausted the grantor's title to that westerly 100-foot strip 15 years before Jones acquired the property. This assumes Smith's deed was recorded before Jones's or that Jones took with notice. Under § 89-5-1, an unrecorded senior deed is not good against a later purchaser for value without notice who records first, so check recording dates as well as execution dates.

The Anatomy of a Gore (Gap)

Suppose the same common grantor in 1980 conveyed "the West 500.00 feet" to Smith. In 1995, the grantor conveyed "the East 450.00 feet" to Jones. The total parent tract measures 1,000.00 feet on the ground.

• $500.00\text{ ft} + 450.00\text{ ft} = 950.00\text{ ft}$.
• A 50.00-foot gap (gore) exists between Smith's east line and Jones's west line.
• Neither Smith nor Jones has legal deed title to this 50-foot strip.
• Crucial Rule: The surveyor has no legal authority to split the 50-foot gore down the middle or extend either party's boundary. Under the usual rule, that 50-foot strip remains the property of the common grantor (or their heirs if deceased). Title can only be acquired through an adverse possession claim under Miss. Code Ann. § 15-1-13 (if open, notorious, hostile, and exclusive for 10 continuous years) or through a corrective deed from the common grantor.

Sequential vs. Simultaneous Conveyances

One of the most critical legal distinctions tested on the Mississippi land surveyor examination is the operational difference between sequential conveyances and simultaneous conveyances.

                             TYPES OF CONVEYANCES
                                      |
         +----------------------------+----------------------------+
         |                                                         | 
         v                                                         v 
   SEQUENTIAL CONVEYANCES                                SIMULTANEOUS CONVEYANCES
   - Parcels created at different times                  - Parcels created at exact same instant
   - Deeds recorded chronologically                      - Recorded subdivision plats
   - SENIOR RIGHTS APPLY STRICTLY                        - Wills / testamentary partitions
   - First deed out gets full call                       - APPORTIONMENT RULE APPLIES
   - Junior absorbs all deficiency                       - Excess/deficiency distributed
   - Overlaps resolved by seniority                        proportionately among all lots

Sequential Conveyances (Deed by Deed)

• Created over a timeline by successive, independent deeds from a common grantor.
• Seniority governs absolutely. Senior tracts take their full dimensions. Junior tracts absorb all shortages and receive any unanticipated remaining surplus only if described as the residue.

Simultaneous Conveyances (Subdivision Plats & Partitions)

• Created at the exact same legal moment in time. The primary example is a recorded subdivision plat (see §§ 19-27-21 to -31 and local subdivision ordinances), where multiple lots are platted and established concurrently.
• Other examples include judicial partition decrees and land devised simultaneously to multiple heirs under a probated will.
• Senior rights DO NOT exist between lots in a simultaneous subdivision. Because all lots were created at the identical instant, neither Lot 1 nor Lot 2 has seniority over the other.
• The Apportionment Rule (Rule of Proration): If a modern boundary survey reveals an excess or deficiency in the total platted block dimension between original exterior monuments, and no original interior lot monuments can be recovered, the excess or deficiency must be distributed proportionally among all the lots in the block according to their platted frontage, unless the plat explicitly reserves the remainder to an irregular lot.

Chain of Title Research: The Mississippi Surveyor's Duty

Mississippi's Standards of Practice require the plat to show all discrepancies between the survey and the recorded descriptions, and the sources used (Rule 7.3). That cannot be done from the client's deed alone. A surveyor who ignores the adjoining instruments risks serious boundary errors and professional liability.

Essential Research Steps in Chancery Clerk Records

1. Locate the Common Grantor: Trace the client's chain of title backward in the county deed records (Chancery Clerk's office) to the grantor who originally owned both the subject tract and the adjoining property.
2. Determine Order of Alienation: Identify the date of execution and date of recording of the first parcel conveyed out by that common grantor to determine which adjoiner holds senior rights.
3. Inspect the Adjoiner's Senior Deed: Read the adjoiner's legal description. If the adjoiner's deed is senior, the boundary line between the properties is fixed by the senior deed description. The junior client's boundary is legally defined by the adjoiner's property line, regardless of what the junior deed's mathematical calls state.
4. Check for Unrecorded Prior Deeds: Under Mississippi's recording statute (Miss. Code Ann. § 89-5-1), a conveyance is not good against a later purchaser for value without notice, or a creditor, unless it is lodged with the chancery clerk for recording. Priority of filing then sets priority among conveyances of the same land. Notice matters: open possession by an earlier grantee can put a later purchaser on inquiry, so document occupation carefully.

Federal and State Patents as Roots of Title

In Public Land Survey System states like Mississippi, all private titles originate from a sovereign Patent issued by the United States General Land Office (GLO) or the State of Mississippi (for swamp and overflowed lands, internal improvement lands, or forfeited tax lands).

• An earlier, valid federal patent conveys legal title out of the sovereign public domain.
• A subsequent patent mistakenly issued by the federal government for the same land is entirely void because the government had already divested itself of title.
• In the historic Natchez District and coastal counties (Jackson, Harrison, Hancock), private land claims based on British and Spanish royal grants confirmed by federal land commissioners predate the regular PLSS surveys and hold senior title over subsequent GLO township section patents.

Common Exam Traps & Retracement Pitfalls

• Applying Proration to Sequential Deeds: The most dangerous trap on licensing examinations. When an exam question presents two deeds created sequentially from a common grantor (e.g., deed in 1972 and deed in 1985) with an unexpected 10-foot shortage, candidates frequently attempt to prorate the shortage 50/50. Never prorate sequential deeds! The senior deed gets its full measurement; the junior deed absorbs the entire shortage.
• Ignoring the Gore: Assuming that because an unmentioned 8-foot strip exists between two fences, the boundary line must run down the center of the gap. A surveyor cannot create property rights. The surveyor must show the gore on the plat, monument the deed corners of both tracts, and note that title to the intervening gore remains in the common grantor.
• Failing to Pull Adjoiner Deeds: Believing that a surveyor's contract only requires surveying the client's boundary description. Rule 7.3 requires discrepancies with adjoining records to be shown, and a boundary monumented without checking the senior adjoiner's deed may be wrong.
