Absolutely not. I'm trying to get a solution from different viewpoints. Plus I didn't know which subject to ask under. The question is the same in both posts but I am trying to keep the issue as specific as possible

Anyway, regardless of anything else, one cannot deny all rights to a property prior to the time where it would be applicable. In other words; disclaiming all rights now does not affect future rights and if we are speaking of a spouse, spousal rights, or the claim to them, accrue continually
The spouse can execute a quit claim deed today but marital interest will begin to accrue immediately after the deed is delivered. What the spouse does is if at the time of death they have any claim to any interest at that time, they would have to disclaim their interest.
Other than transferring it prior to death or using a transfer on death vehicle, there is always the issue of the possible claims of the spouse
