# Anti-Washout Clause

An anti-washout clause is a provision protecting an overriding royalty interest (or similar carved interest) from being "washed out" when the underlying lease terminates and is re-acquired, by extending the override to any extension, renewal, or new lease the working-interest owner takes on the same lands — so the interest survives a lease turnover instead of disappearing with the old lease.

## The washout problem
An overriding royalty interest is carved out of a lease and, by nature, dies when that lease dies. That creates a temptation and a trap called a washout: the working-interest owner lets the burdened lease lapse (or surrenders it), then takes a new lease on the same land — and because the override was tied to the old lease, it vanishes, while the operator keeps producing the same minerals free of it.
Whether done deliberately or through ordinary lease turnover, a washout can wipe out an override the holder expected to last as long as production. The anti-washout clause exists to stop it.

## How the clause protects the interest
An anti-washout clause provides that the override attaches to any extension, renewal, or new lease the working-interest owner (or its affiliates) obtains covering the same lands, for a defined period. If the old lease ends and a new one is taken, the override rides onto the new lease automatically, preserving the holder's cost-free share.
Well-drafted versions close the common loopholes: they reach top leases and new leases taken shortly after surrender, cover affiliates and successors so the interest cannot be washed out through a related entity, and sometimes extend for a stated number of months after any termination.

## Where anti-washout clauses appear
These clauses live in the assignment that creates the override — a farmout, a sale of a lease with a retained override, or a compensation grant to a landman or geologist. Anyone accepting an override as payment or retaining one in a deal has a strong interest in a robust anti-washout provision, because without it the override is only as durable as the current lease.
The same logic can protect other lease-dependent carved interests, but the override is where anti-washout language matters most.

## Why it matters when valuing an override
Because an override's lifespan is tied to a lease, the presence and strength of an anti-washout clause is a central question in valuing one. An override with solid anti-washout protection is far more durable — and more valuable — than a bare override that a routine re-lease could extinguish. A buyer reads the creating assignment specifically for this language.

## Frequently asked questions

**What is an anti-washout clause?**
A provision that protects an overriding royalty (or similar carved interest) from being washed out when the underlying lease terminates and is re-acquired, by extending the interest to any extension, renewal, or new lease the working-interest owner takes on the same lands.

**What is a washout of an overriding royalty?**
When the working-interest owner lets the lease burdened by an override lapse or surrenders it, then takes a new lease on the same land — extinguishing the override, which was tied to the old lease, while the operator keeps producing free of it. An anti-washout clause prevents this.

**How does an anti-washout clause protect an override?**
It provides that the override attaches to any extension, renewal, or new lease the working-interest owner or its affiliates obtains on the same lands, so the interest rides onto the new lease automatically. Strong versions cover top leases, affiliates, and successors to close loopholes.

**Where is an anti-washout clause found?**
In the assignment that creates the override — a farmout, a lease sale with a retained override, or a compensation grant. Anyone accepting or retaining an override should want a robust anti-washout provision, since without it the override lasts only as long as the current lease.

**Does an anti-washout clause affect an override's value?**
Significantly. An override with strong anti-washout protection is far more durable, and more valuable, than a bare override that a routine re-lease could extinguish. A buyer reads the creating assignment specifically for this language.
