Yes. A party may be able to receive credits and/or offsets for upgrading a property in a partition action under many circumstances. In a partition lawsuit, two parties disagree about what to do with the jointly-owned property.
In those circumstances, one party can seek the sale of the property and then have the equity divided between all of the owners. Once the property is sold, the parties can make claims to the money left from the proceeds from the house.
One issue that often arises, however, is whether an improvement to the property—as opposed to a repair—is subject to an offset as part of the partition action. For example, if one party remodels a bathroom, would they have the right to an offset for that work?
