Key legal question
Whether the auction terms could validly provide that the ground rent obligation passes to the purchaser.
Extracted holding
Yes. In a bankruptcy sale of a leased building right, where a securing mortgage for the ground rent is entered, the personal ground rent duty may be transferred to the purchaser through the auction terms.
Extracted reasoning
The ground rent itself is a personal obligation, but in foreclosure it follows the system of transfer with the property. Since the security mortgage remains and secures future rent, the auction conditions may lawfully impose the corresponding payment duty on the bidder.
