Are anti-stacking clauses in Georgia UM policies enforceable?


Anti-stacking clauses, which try to stop an insured from combining uninsured motorist limits, can be enforceable in Georgia, but only to the extent they are consistent with the UM statute and clearly written. The enforceability question turns on whether a clause conflicts with the protections O.C.G.A. § 33-7-11 builds into UM coverage and whether its language is unambiguous.

The tension between policy language and the statute

An insurer drafts its own policy and may include “other insurance,” “anti-stacking,” or limit-of-liability provisions intended to cap how UM coverage combines across vehicles or policies. Georgia courts will give effect to clear policy terms, but they read those terms against the backdrop of the UM statute, which exists to guarantee a minimum of first-party protection. A clause that would cut UM coverage below what the statute requires, or that contradicts the coverage the insured paid for, is vulnerable.

Two principles do a lot of the work here. First, ambiguities in an insurer-drafted policy are construed against the insurer and in favor of coverage. Second, a private contract term cannot override a statutory entitlement. So a clearly worded clause consistent with the statute may stand, while a vague or statute-defeating clause may not.

What tends to make a clause hold or fail

Courts look closely at the wording and context. Considerations that commonly matter:

  • Clarity. A clause that plainly and specifically limits stacking is far more likely to be enforced than one a court finds ambiguous.
  • Separate premiums. Where the insured paid a distinct UM premium for each vehicle, an insurer faces a harder argument that those coverages cannot combine.
  • Statutory floor. A clause cannot reduce coverage below what O.C.G.A. § 33-7-11 mandates.
  • Insured status. The analysis can differ for named insureds and resident relatives, whose coverage follows them, versus mere occupants.

Why the answer is rarely all-or-nothing

Because enforceability depends on the precise language and the specific facts, the same general type of clause can be upheld in one policy and struck down in another. The outcome is driven by how the clause is drafted and how it interacts with the statutory protections, not by the label “anti-stacking” alone.

The bottom line

Anti-stacking clauses in Georgia UM policies are not automatically valid or invalid. A clear clause that respects the statutory minimum can be enforced, while an ambiguous clause, or one that would shrink coverage below what O.C.G.A. § 33-7-11 guarantees or below what the insured separately paid for, may not be. The specific wording controls.
