We have life insurance and critical illness/unemployment insurance. I made a will before I met Tom after my divorce so my ex couldn't try to claim anything. My will currently stands that my dad and sister get 50% each of the house and my life insurance. If anything happens to me while I work for the police Tom gets a payout plus all my pension. My Dad and Lindsay both know that, if anything happens to me, my life insurance pays the mortgage, the house is put straight into Cole's name but Tom can live there indefinitely and Tom gets any leftover money from my life insurance.
Once I'm back at work and getting paid again we're going to make a joint will that says if one of us dies our life insurance pays the mortgage and the house goes straight into Cole's name then any money is for me/Tom to live on. Even though the house is in my name if anything happens to Tom I'll pay the mortgage off with his life insurance then put the house in Cole's name so if I ever meet anyone else they have no claim to it over Cole. We won't tell Cole the house is in his name, we'll put a clause in saying he can only claim it once we have both died, but it protects it for him. It's complicated because technically it's my house (I've had it 10 years) but Tom pays half of everything and isn't bothered about his name on the mortgage as we're both agreed it's Cole's (and any subsequent children's) house.
