The way many older couples do this is to say the surviving spouse can have the house for life, but when they die the estate goes to the owner's children.
It's a straightforward process usually, so don't take notice of the 'scare' tales.
A good friend of ours did this. She married a widower in her 50s (she was widowed too) and sold her own small house which was worth less than his.
The agreement was she could have the house for life then his children would sell it and it would be their inheritance.
In effect, she went into a care home for a couple of years, at which point the house was sold and his children inherited.
Does your partner own a home? If he does, he'd be wise to rent it out.
If he doesn't where would he live if you die first? Would he have to start renting in his 70s or 80s? What's his income like?
How old are you both? Unless he is significantly younger the odds are you will outlive him.
