Understanding Contracts: Types and Elements

Defining Contracts and Parties

Contract Definition

A contract is a verbal or written agreement between two or more persons who are obliged to give, do, or refrain from doing anything or providing any service.

Individuals

Individuals are natural persons who possess personality, rights, and obligations.

Legal Entities

Legal Entities include partnerships, corporations, associations, and foundations with a legal personality separate and distinct from their members. These members can be natural persons or other legal entities. Legal entities act through representatives or administrative/management bodies composed of natural persons.

Types of Contracts

By Form

  • Verbal Contracts

    These take place by word of mouth.

  • Written Contracts

    These are reflected in a written document.

By Legal Regulation

  • Typical Contracts

    These are regulated by the Civil Code, Commercial Code, or special laws.

  • Atypical Contracts

    These are created by the will of the parties and do not conform to the characteristics of typical contracts regulated by law.

By Applicable Law

  • Civil Contracts

    These are private agreements concluded between parties who are not merchants. They are regulated by the Civil Code.

  • Commercial Contracts

    These are concluded between traders or entrepreneurs in their professional business. They are regulated by the Commercial Code.

  • Administrative Contracts

    These are agreements between public administrations and companies. They are governed by public administrative law.

  • Labor Contracts

    These involve workers voluntarily offering their services for remuneration to an employer. They are regulated by labor law, which governs the status of workers.

By Bargaining Power of the Parties

  • Equal Contracts

    Both parties negotiate and agree on the terms until an agreement is reached.

  • Adhesion Contracts

    The contract terms are set by one party, and the other can only accept the terms without modification or choose not to contract. Examples: water, telephone, gas supply, etc.

The Sales Contract: Key Aspects and Obligations

The Tangible Sales Contract (CV)

Object of the Contract: The Property

The property refers to the tangible item the seller delivers to the buyer, known in trade as goods or merchandise.

The Price

The price is paid in cash or a representative instrument (check, bill of exchange, promissory note, etc.). It can also be paid partly in money and partly in an instrument. The price must be genuine, a fixed amount at the time of contract award, or determinable later without a new contract.

Elements of a Sales Contract: Parties

Seller and Buyer

Based on how the price is set, two classes of sales emerge:

  • Fixed Price

    The price is set at the time of contract award and cannot be modified later, even if agreed conditions have changed.

  • Variable Price

    The parties may allow for price variations based on factors such as market circumstances.

Obligations Arising from a Sales Contract

Seller’s Obligations

  • Preserve and guard the item in perfect condition.
  • Deliver the item at the agreed time and place.
  • Provide warranty against eviction and hidden defects (when the item sold is defective and the defects are not visible to the naked eye).

Buyer’s Obligations

  • Pay the price at the agreed time and place.
  • Pay off the price if payment is deferred.
  • Receive the purchased item.
  • Pay for transportation, unless otherwise agreed.

Special Sales Contracts

Installment Sale

This is where part of the price is paid upon delivery of the goods in generally equal or periodic fractions.

Place-to-Place Sale

This arises when merchandise is transferred from one locality to another. These contracts often utilize a number of clauses called Incoterms (EX WORKS, FAS, FOB, C&F, CIF, and Free at Home) or international commercial terms.

Supply Contract

A contract where one party provides successive and periodic deliveries of specific goods to another for a fee.
