In real estate, words such as erosion, accretion, avulsion, and reliction do carry legal consequences, especially property rights along streams of water. Erosion is the general wearing down of land, normally through natural action such as wind, water, or ice.

This process, however, can lead to changes in property boundaries, impacting landowners’ rights. Let’s explore how erosion and other related processes affect property ownership and rights, especially along waterfronts.

What is erosion in real estate?

Erosion, in real property, is the slow destruction of land by natural forces, most commonly water or wind. It has the impact of diminishing a property over a period of time, particularly if the property is located on the edge of a river, lake, or ocean. Slow erosion of land can have implications on the rights of owners and the property value.

Erosion would normally cause a reduction in land area of a property, which could give rise to conflict between property owners. In such situations, outlining the legal status of property boundaries becomes of utmost importance.

The sudden loss of land through natural causes is called avulsion

Unlike erosion, which occurs gradually, avulsion refers to the sudden loss of land due to natural events like floods or earthquakes. Avulsion can result in significant changes to a property’s boundaries almost overnight. For example, if a river changes course after a heavy flood, the land previously located on the other side of the river may suddenly belong to a different property owner.

Property rights in such cases can be complex, as the law typically recognizes the immediate shift of land, but the affected property owner may be entitled to compensation depending on local regulations.

How is erosion the opposite of accretion?

While erosion involves the gradual loss of land, accretion refers to the gradual buildup of land. Accretion occurs when natural forces such as water or wind deposit sediments, creating new land. This process often happens along shores, riverbanks, or beaches.

In real estate, the process of accretion can increase the size of a property, giving the property owner new land. Typically, the newly formed land belongs to the adjacent property owner. This process is considered the opposite of erosion because instead of losing land, a property owner gains land.

What are littoral rights in real estate?

Littoral rights concern property owners whose lands border a water body, e.g., an ocean, sea, or lake. Littoral rights give property owners rights to the use of the water and its resources and the right to be able to move to the water. Littoral rights are restricted and are controlled by state or local statute.

Owners of land with littoral rights generally own up to the high-water mark but not the water itself. Those who own waterfront land should be aware of littoral rights since changes in the water edge (through accretion or erosion) affect their title to land directly.

Reliction and its effect on property ownership

Reliction is a legal term referring to the gradual recession of water, exposing land that was previously submerged. This often happens when a body of water recedes due to changes in water levels or water usage. When land is exposed due to reliction, the property owner typically gains rights to this newly uncovered land, similar to how accretion works.

Reliction is particularly important for property owners along lakes or rivers, as it can create new land that becomes part of the property. However, the rules around reliction can vary depending on local laws, so property owners should understand the legal implications of this process in their jurisdiction.

The legal implications of erosion, accretion, and avulsion on property ownership

The legal impact of erosion, accretion, and avulsion is significant, particularly when it comes to determining property boundaries. In many cases, property owners may not be aware of how changes in land due to natural forces can affect their legal rights.

  • Erosion can reduce the size of a property, potentially causing disputes over land ownership between neighboring property owners.
  • Accretion increases land size, allowing property owners to expand their holdings.
  • Avulsion leads to sudden changes in boundaries, which can create conflicts over ownership of the new land.
  • Reliction exposes new land, which typically becomes part of the adjacent property, provided the landowner claims it in accordance with the law.

Property owners need to be aware of these processes and their potential impact on land ownership. In some cases, state laws may grant property owners the right to reclaim land lost due to erosion or avulsion, while in other cases, the process may require legal intervention to resolve disputes.

How to protect your property from erosion?

Even though erosion is natural, landowners are able to take certain precautions in order to maintain their land from severe loss. Some of these steps are:

  • Building seawalls, ripraps, or jetties as walls to prevent erosion at waterfronts.
  • Seeding vegetation like grasses and shrubs anchor the soil and prevent erosion by wind and water.
  • Recurring patrol of the property boundaries to observe changes in land and catch erosion threats early.
  • Employing professionals such as engineers or environmental consultants to assess erosion risks and develop successful protection strategies.

Incorporating these interventions will help to protect the integrity of your land and prevent wastage by forces of nature.
