# Entireties Clause

An entireties clause is a provision in an oil and gas lease that directs how royalty is apportioned among owners when the leased tract is later divided — generally requiring royalty to be shared across all owners in proportion to acreage, rather than paid only to the owner of the tract where a well happens to sit.

## The problem the clause solves
When a single leased tract is later subdivided — sold in parts, or split among heirs — a question arises: if a well is drilled on one parcel, does that parcel's owner get all the royalty, or is it shared with the others who were part of the original lease? Without guidance, the default in many states (the "nonapportionment rule") is that only the owner of the parcel with the well is paid.
The entireties clause overrides that by directing the operator to apportion royalty across all the subdivided owners in proportion to their acreage, as if the tract were still whole. It keeps the original owners sharing in production regardless of exactly where the wellbore lands.

## Why it matters to a mineral owner
For an owner whose land might later be split — or who inherited a piece of a once-larger leased tract — the entireties clause can be the difference between receiving a proportional royalty and receiving nothing because the well sat on a neighbor's parcel. It is one of the many lease terms that quietly determines who gets paid, alongside pooling, Pugh, and shut-in clauses.
When Buckhead Energy evaluates an interest carved out of a larger original tract, the lease's apportionment language is one of the title questions that affects the decimal — and therefore the value.

## Frequently asked questions

**What is an entireties clause?**
A lease provision that directs how royalty is divided when the leased tract is later subdivided — generally requiring royalty to be shared across all owners in proportion to acreage, rather than paid only to the owner of the parcel where a well sits.

**Why does an entireties clause matter?**
Without it, many states pay royalty only to the owner of the subdivided parcel that has the well. The clause keeps all the original owners sharing in production proportionally, which can be the difference between a royalty and nothing for owners whose parcel has no wellbore.
