Sorry for your loss. You need to call honda and transfer the lease I guess - to be fair your attorney is very knowledgeable, so this might be wrong - but you usually have to call an FS to inform them to have it transferred.
This information may have changed since 2017, but it is a good starting point to try and resolve this affair. Most FS’ that usually don’t allow transfers make exceptions to that policy for the leasee’s death. In this case, I guess transferring to you, then you selling through the aforementioned dealer or brokers would be the best way to utilize that equity.
