Does Alabama Allow UM/UIM Stacking? What the Statute Says

By the FigureMyTax Editorial Team · How we calculate

Yes, within one policy. Ala. Code 32-7-23(c) allows the primary coverage plus additional coverage for additional vehicles, but never more than two additional coverages in the same contract.

The statutory text

The rule sits in Ala. Code 32-7-23. Subsection (c) says the recovery by an injured person under the uninsured provisions of any one contract of automobile insurance is limited to the primary coverage plus such additional coverage as may be provided for additional vehicles, but not to exceed two additional coverages within that contract.

Why the cap is three, not unlimited

The statute counts coverages, not vehicles. A household with four cars on one policy still counts one primary and two additional coverages. See the difference in dollars in our stacked versus unstacked explainer.

What the statute does not say

The text we read limits recovery under any one contract. It does not address combining coverage from separate policies, and we found no primary source that does. An injury firm's summary says Alabama lets injured people stack two additional coverages on top of the primary coverage on claims involving single multi-vehicle policies; whether and when separate policies can be combined is a question for your insurers and an attorney.

Coverage is automatic unless rejected

Section 32-7-23(a) requires UM coverage in a covered auto liability policy "unless" the named insured rejects it, and says a rejected coverage need not be provided in a renewal unless the named insured requests it in writing. If you never rejected it, assume you have it and check the limits.

When stacking cannot help

Stacking only matters if UM/UIM is triggered. If the at-fault driver's liability coverage already covers your damages, nothing is left for UM/UIM to pay. Use the Alabama UM/UIM stacking calculator to see whether your numbers leave a gap.
