Legal Definitions - per aversionem

Per aversionem is a Latin term that means "for a lump sum." It is used in Roman and civil law to describe a type of sale where goods are sold in bulk or land is bought by estimating the number of acres.

The term is used because the buyer does not carefully examine each item before purchasing. Instead, they buy everything together for a single price.

For example, if a farmer wants to buy a large quantity of wheat, they might purchase it per aversionem. This means they buy all the wheat together without examining each individual bag.

Another example is if someone wants to buy a large piece of land. They might estimate the number of acres and purchase it per aversionem. This means they buy the land without examining each individual section.

In both examples, the buyer is taking a risk because they are not examining each item individually. However, the sale is considered complete once the buyer pays the lump sum price.
