Spousal Consent On Purchase Agreement

[Belinda D.]

I cannot find the answer to this under the search tab:

Scenerio 1: Husband and wife are living in the matrimonial home, but wife is not on title.   If they decide to sell the house, does the wife need to sign the Purchase Agreement?

Scenerio 2: Matrimonial home is vacant and husband and wife are separated or getting a divorce. Husband wants to sell and wife is not on title. They are not speaking to each other. Can he sell without her signature or does he have to wait to see the conditions of the separation agreement or divorce decree?

Thanks.
