I live with my partner and have done for many years. We have no dependent children and our house is owned as tenants in common.
We both have jobs which pay out if we die to the spouse automatically but I am not sure if I am on my partners. He is on mine.
We don't really discuss finances or wills or NOK issues as we are both a bit vague in this type of thing, but DP had a recent health scare and I think we need to look at protecting one another. Don't want all the hassle of marriage so what do we do?
