A grants a life estate in fee to B and thereafter to C. C holds a?

In this scenario, C holds a remainder interest. A remainder interest is a future interest that becomes possessory when a life estate ends. In this case, B is given a life estate, which means that B has the right to use and occupy the property during their lifetime. Once B passes away, C, as the remainderman, will receive full ownership and control of the property.

The concepts of dower interest, lien interest, and curtesy interest do not apply in this situation. Dower and curtesy are traditional common law concepts that granted surviving spouses a life estate or interest in the deceased spouse's property upon their death, which is not relevant here. A lien interest refers to a legal right or claim against an asset, typically used to secure a debt. In this context, we are concerned with ownership rights rather than claims against the property.

Thus, since C's interest depends on the termination of B's life estate, C's interest aptly fits the definition of a remainder interest.
