So sorry to hear about your loss. I unfortunately can relate. My father past away 2 months before I went to seminary and I had to fill out things still at that point not application but info stuff for the school. My sister this year is actually in seminary and what we both did/ do in the circumstance is you fill out the space with your father’s name ??? and then by contact stuff put N/A but they might wanna know things about who he was like questions about his past but things that refer to the present put N/A (non applicable)
I unfortunately cannot help with info on chemdas I do not know anything about it but lots of luck!
