Nolo's Plain-English Law Dictionary


An out-of-the-ordinary increase in property that goes to the property owner. In real estate, accretion is an increase in land that results from the deposit of soil by a river or ocean. Accretion also occurs when someone who inherits assets receives more than expected because another beneficiary dies or doesn't accept a share, or when trust assets increase due to some unexpected and unusual event.
