The home is usually the largest asset of the parties, especially if substantial equity exists. If minor children are involved, a court is unlikely to order a sale of the home, which seems like the most equitable way to resolve the issue. Courts have viewed this issue in different ways, but the most common is to allow the custodial parent to retain the home to avoid major change for the children while the other party receives other assets to offset the value of the home. This is only possible when the custodial parent would be able to pay the bills associated with the home.
It's also possible for the custodial parent to secure refinancing in order to buy out the interest of the other party. If a buy-out or offset is not possible, the parties may continue to own the home as tenants in common, but the parties need to be able to work together on the maintenance, repairs and upkeep.
No matter the resolution, a residential appraisal should be done on day one so both parties are fully aware of the value of this asset. It's likely that the home will be sold at some point, and it's important to track the value from day one.
