Martin Lewis is urging couples who live together but are not married to have arrangements in place that will help manage their assets when they die.
If they don't want to tie to knot, the MoneySavingExpert founder said couples should either get a will, civil partnership or some other form of contract to lawfully inherit their partners assets.
Martin said in the latest MSE newsletter that those who are not married or in a civil partnership have no status under inheritance law.
