Gifted property with no notice

[Steve Barrett]

Interesting occurrence...

My wife’s grandmother has decided to deed her house to my wife. She told us she was going to do it, but we thought it would just be an estate issue. 

I searched the tax rolls today and see that, in fact, my wife is now listed as the “Special Warranty Gift Deed” holder.

I don’t understand how this can happen without my wife having signed or even really agreed to accept it.

Thoughts?
