Paul McCartney is purported to have written the melody to “When I’m Sixty-Four” around the tender age of 14. Sir Paul, course, has long since passed the milestone memorialized in that song, and for an increasing percentage of the legal profession’s baby boomer generation, it is also passing by in the rearview mirror.

By the same token, what may have been traditional notions of retirement age a generation ago no longer apply with the same degree of uniformity, as an increasing number of lawyers maintain vigorous practices throughout their 60s and into their 70s or even beyond, working in law firms that impose no mandatory retirement age. But regardless of whether firms mandate retirement or not, they all share a common concern, which is how to ensure the preservation and eventual transition of client relationships to the next generation.
