You will hear people talk about "elder lawyers" sometimes as a solution to certain problems with older folks. They don't mean old lawyers, they mean people focusing on the needs of the aging population.
But what is the practice of "elder law?" It's tricky, and involves a whole range of disciplines. Elder law has certain facets which are more commonly used (Medicaid or Social Security applications, disability laws, asset planning, wills & trusts...) but it is not at all surprising to run into any of a number of different practice areas during a brief consultation or an entire case. Elder law attorneys need to be versed in a wide variety of laws, and know how to reach out for help when the answer is not immediately forthcoming.
