I thought being married meant your partner and child got your assets! My financial advisor or solicitor (can't remember which) said it'll be a waste of my money making a will for this reason.
A lot of it depends on how the major things are set up. If you are set up as joint tenants for your house (tenants just as in 'people who occupy the house' - not renters, as it only applies to people who own their home) and you have all of your money in a joint account(s), your spouse won't so much 'inherit' what you leave as automatically take over in full any joint assets which you have forfeited any claim to by dying!
I suppose car ownership could be slightly more tricky as cars can't (AFAIK) be registered to more than one owner. Most other things that are already in the house would just be naturally taken over by the surviving spouse, unless there was somebody to challenge them over items that specifically and provably belonged to you only, as opposed to furniture or kitchen appliances. It's a sobering thought that most people's everyday chattels, which they spent a lifetime accumulating, would be valued at maybe £500 at the very most - unless you have valuable jewellery or paintings etc, its basic second-hand market-value status will be as 'junk'.
Even if somebody did challenge them, surely a spouse would be awarded the possessions over anybody else, unless they could make a solid legal case with proof to the contrary?
Life assurance and critical illness cover are not an option (for me at least, because of my various medical conditions and family history). We probably should make a will sometime soon, although the only thing that really concerns me is who would look after our DS if we both died before he was an adult. Everything else would go to the surviving spouse, or our son if we both died, and then, after that, presumably any surviving parents and then our sisters, which is what we'd choose anyway (parents would almost certainly pass half each straight to our sisters anyway).
Of course, anybody can die at any time, but going purely on probability, most of us will likely get (or have already had) Covid-19 and suffer minor or no effects. Those who have sadly died are naturally devastating for their families and friends, but statistically, it's an extremely tiny percentage - especially as we don't have widespread testing yet and, even when we do, many of those who do die will have done so with CV rather than necessarily exclusively from it.
