Ex moved out a year ago and we agreed he would pay half of mortgage and then when we sell he gets half of obey from house sale. However, he’s stopped paying now leaving me which the full mortgage and laughing about he’s still getting half of the house when we sell in a few years (a few years because I have young children and need to get back to work to get a mortgage by myself). Is there anything I can do to protect the amount I’m paying now? Anything that can be put in place to show I’ve paid the mortgage from this point? Thanks , I’m just so stressed.
