How old are you? How is your health?
How do you compare to your STBX as it relates to education?
Your STBX is 60 years old so what was his previous employment? Does he have a pension? 401K? You are entitled to your marital half of those funds.
You would NOT be giving your SBTX half of your 401k. You would be giving him half of what accrued during the marriage only.
Let's be clear - you say that your name is not on the mortgage - are you referring to the mortgage note? But you are on the Deed?
Is he receiving unemployment benefits?
Why did you leave the home and incur additional rent expense?
Is he able to cover utilities, car insurance, medical insurance, food?
