I am not sure how the legal end of this works either. But as far as communication goes, you can ask her why she wants to do this? Did you have kids and now you have an empty nest. so your wife wants a project, for example. If you can talk about the underlying reason why she has a desire to take on a real estate project, you can better determine a resolution. I wouldn’t use her desires as a bargaining chip, but I definitely agree with the last person who posted – maybe you could both move forward together in achieving what you both desire (she gets real estate, you get “fill in the blank”). There may also be a piece of this real estate project you could help out with – a part of the project you would enjoy.
