Buying and selling personal property, and the property has no other owner, does not require the signature or consent of the spouse.

If the house is personal property before marriage, and there is no agreement between the owner and the husband and wife on the house, the owner does not need the consent and signature of the spouse to sell the personal property under his name, but only needs the owner to sign the power of attorney to sell the house, but the notary office needs to make a record of the spouse to confirm the above facts.

However, there are exceptions. If there is a marital property agreement similar to the joint property of husband and wife, then the owner needs the consent of the spouse to notarize the power of attorney for selling the house, and both husband and wife need to sign the power of attorney for selling the house.
