Roman Contract Law: A Comprehensive Guide

Roman Contract Law

Consensual Contracts

Source

Consent of the parties regarding the delivery obligation, not necessarily involving a physical item.

Features

  • Expression of will
  • Consensual obligation by consent of the parties (e.g., sale, lease, partnership, mandate)
  • Creates obligations and rights enforceable by both parties
  • Arises from consensual agreement and ends by various means (e.g., error, fraud, duress)

Execution and Unfulfilled Contracts

One party can refuse to perform if the other party doesn’t fulfill their obligations. A valid contract includes three elements: Conclusion (agreement), Perfection (necessary conditions present), and Enforcement.

Purchase and Sale

A seller agrees to transfer legal ownership of an item to a buyer, who, in turn, is obligated to pay a price.

Duties

  • Seller: Deliver the item
  • Buyer: Pay the agreed price

Evolution

  • Barter: Exchange of goods
  • Mandate: Delivery of the item
  • Stipulation: Formal promise to comply
  • Good faith obligations beyond the delivery of the item

Requirements

  • General legal capacity (e.g., curators cannot buy property they manage)

Elements of the Purchase and Sale Contract

  • Thing: Can be sold or not (e.g., inalienable property)
  • Sale of expected goods: Payment is due even if the goods do not materialize
  • Price: Sum of money
  • Consent: Agreement between the parties

Proof of Consent (Arras)

A quantity delivered to the buyer by the seller as proof of consent.

Effects of the Contract

  • Buyer: Pays the price; if late, pays interest. Bears the risk of loss.
  • Seller: Transfers possession and custody, liable for fraud and defects.

The seller must guarantee against defects (Law of the Twelve Tables) and disclose any flaws, or pay double the price within six months or reduce the price within a year.

Lease

A lessor agrees to provide a lessee with the use of a thing for a specific time in exchange for payment, with the thing returned at the end of the term.

Obligations

Bilateral contract with reciprocal obligations, transferable to heirs.

Elements

  • Thing: The object of the lease
  • Price: Must be real and certain

Classes of Lease

  • Lease of services: A person provides services for a salary
  • Lease of work: The lessee performs work on a thing provided by the lessor

Effects and Termination

The lessor is responsible for defects that prevent use. Termination occurs due to loss of the thing, end of term, non-payment, or unsuitability of the thing. It does not end with sale or donation.

Renewal and Eviction

Renewal can be tacit or express. Eviction is the lessor’s right to reclaim the property.
