Domestic problem tenant

[John R Kepler]

This weekend the female tenant of one of my properties called requesting I take the male tenant off the lease as they split up. The last thing I want is to be in the middle of this dispute. Both names are on the lease and listed as being financialy responsible. I have had no communication with him. At the moment I am in a holding pattern to see if this works itself out. My question is how to proceed legally and ethically with regards to the lease and deposit. Appreciate any advice.
