Imagine that you're a landlord in Santa Monica and you've rented a place to an elderly tenant for a long time for $666/month. After he dies, you want to increase the rent for the place to the market rate, which is $3500/month. But his caregiver apparently married him a little over a year before he died, and says that she's entitled to stay in the place at the original rate. So you have your attorney file an eviction action, and it proceeds apace.
Then imagine that you see who's representing the surviving tenant: Munger, Tolles & Olson.
Shucks for you.
P.S. - The landlord loses.
