What are the invalidating factors of a contract?

• What Invalidates a Contract?

Contract invalidators are reasons or situations that render a contract absolutely null and void from the beginning — as if it never existed. Such a contract produces no legal effect and cannot be rectified later by unilateral will or even mutual agreement.

• Cases in Which a Contract is Invalidated (Absolute Nullity):

1. Lack of Consent or the Presence of a Fundamental Flaw

- Such as coercion or duress.

- Mistake regarding the essence of the subject or the person, if essential.

- Fraud that affects the contracting party’s will.

2. Lack of Legal Capacity to Contract

For example, if one party is a minor or entirely lacks legal capacity.

The contract is considered absolutely null and void if made by a person who completely lacks contractual capacity (e.g., someone insane or mentally incompetent).

3. Illegality of the Subject Matter or Purpose

For instance, a contract involving the sale of prohibited substances or aiming to commit an unlawful act.

4. Violation of Public Order or Morality

Such as contracts that interfere with the judiciary system or conflict with religiously established family law provisions.

5. Absence of One of the Essential Elements of a Contract

These are: (consent – subject – purpose – capacity).

If any of these elements is missing, the contract is considered absolutely void, has no effect, and does not bind anyone.

• What Are the Consequences of a Void Contract?

- It is treated as if it never existed.

- Parties are returned to their pre-contract position (if possible).

- Neither party can rely on the contract’s terms.

- Compensation may be claimed in some cases (if damage results from an unlawful act through the contract).

• Legal Advice:

To ensure the validity of the contract:

- Make sure there is genuine and lawful consent.

- Verify the other party’s legal capacity.

- Consult applicable laws when drafting the contract’s subject or purpose.

• Recommendation:
