Dissipation of marital assets occurs when one spouse spends marital money in an improper or wasteful manner, generally during the breakdown of a marriage. Excessing spending, hiding money, gifting property, or otherwise squandering assets through gross financial mismanagement or in an extramarital relationship would constitute the dissipation of marital assets. If you suspect or discover evidence of dissipation, you will need to work closely with your attorney to keep track of funds and make a dissipation claim with the court.
