A more thorough explanation:

Estover refers to the wood that a tenant is allowed to take for necessary supplies such as fuel, agricultural instruments, fences, and hedges. This right to obtain wood is also known as the tenant's right to estover.

For example, if a farmer rents a piece of land, they may have the right to take wood from the property to use as fuel for their home or to repair their farming equipment. This wood is considered estover.

Estover can also refer to alimony, which is the financial support paid by one spouse to another after a divorce. However, this usage is less common.
