When discussing special provisions in disability insurance, what specifically covers legal and other related expenses?

The correct answer highlights that additional benefits within a disability insurance policy can cover legal and other related expenses. This provision is designed to provide extra support for policyholders who may incur costs associated with legal actions or other services directly arising from their disability claim or the consequences of their disability.

For instance, if a policyholder needs to engage legal services to enforce their policy benefits or address disputes that arise as a result of their claim, additional benefits can help cushion those financial demands. Such a feature enhances the overall value of a disability insurance policy, as it acknowledges the complex situations that can arise beyond merely compensating for lost income.

In contrast, the other options do not pertain to covering legal and related expenses in the same manner. A waiver of premium facilitates the process where the insured does not have to pay their premium during a period of disability, while a legal rider is not a standard term in disability insurance but might refer to adding specific legal protections to a policy. Lastly, a cost of living adjustment is designed to increase the benefit amount as living costs rise, which does not encompass legal costs or related expenses directly.
