Trouble in paradise, tenants looking to divorce, both want to stay without the other

[Boyd Sutherland]

Quick overview - Tenants have been in the house for +/- 16 months, their initial 1yr lease is now month to month.  Rent has been punctual, they are great tenants.  House is located in SW Oregon.

In the past month, both the husband and the wife have reached out to me individually letting me know that divorce is on the horizon, and both have expressed an interest in staying in the house, sans partner.  Both are listed on the lease agreement, both are employed with the local school district with steady, long term jobs.  What is/are the best course/s of action here?  I have a direction that I am planning on, but wanted to put it out to the community think tank to get different experiences/perspectives.
