During the divorce process, one spouse may be able to temporarily prevent the other from selling or refinancing the house by:

1. Filing a lis pendens: A legal notice that alerts potential buyers or lenders of the pending divorce and dispute over the property.

2. Obtaining a restraining order: A court order that temporarily restricts the other spouse from selling, refinancing, or encumbering the property.

3. Including a provision in the divorce agreement: A clause that requires both spouses' consent for any sale, refinance, or encumbrance of the property.

4. Seeking a court order: A judge may grant an injunction or other relief to prevent the sale or refinance if it would unfairly impact one spouse's interests.

However, these measures are typically temporary and intended to maintain the status quo until the divorce is finalized. Ultimately, the court will determine the division of assets, including the house, based on the divorce agreement or state law.

To prevent unnecessary delays and conflicts, it's crucial to consult with a divorce attorney and explore alternative solutions, such as:

1. Mediation or counseling

2. Temporary agreements or stipulations

3. Cooperative divorce negotiations

Remember, every situation is unique, and the specific circumstances and local laws will influence the outcome.
