Yes. This language exists in some leases. The language typically states that if the end of the world is imminent, the landlord has the right to accelerate rents for the remainder of the term. 

There are still a few hours left to check your leases for this language before the eclipse arrives today. 

Happy eclipse viewing today. And, good luck trying to collect with that clause!

We will be back to a regular lease administration post next week. Today, I am in Tennessee to see the eclipse!
