accretion - Legal Definition
- In property law, the gradual increase in land through natural processes; for example, the creation of land caused by the deposit of sediment on a shoreline of a river or ocean. The new land becomes the property of the owner of the property to which it is attached. See also alluvion, reliction, and avulsion.
- In succession law, the increase in an heir or legatee’s interest in property when a co-heir or co-legatee dies before the property vests, rejects his inheritance or legacy, fails to comply with a condition to be met before vesting, or otherwise becomes incapable of taking the property.
