Football player contracts: structure, essential clauses and common errors
A professional football player contract is not a simple employment agreement. It is the document that defines your career: how much you earn, how long you are involved, what happens if they want to fire you, what happens if you want to leave, and who is responsible if things go wrong.
The problem is that many players — especially young players who sign their first professional contract — do so without really understanding what they are signing. And mistakes in a football contract are not easily corrected: they can cost you years of career, money, and transfer opportunities.
In this article you will find everything you need to know about player contracts according to FIFA regulations (RETJ, July 2025 edition), with practical explanations about structure, key clauses, regulatory limits and the most common errors we see in the industry.

What makes a contract valid according to FIFA
For a player to be consideredprofessionalunder the RETJ, you must meet two simultaneous requirements (art. 2): have awritten contractwith a club and receive aremuneration greater than expenseswhich he generates from his football activity.
Without a written contract, there is no professional status. Without professional status, there is no formal transfer, no RETJ contractual protection, and no access to the Football Tribunal's dispute resolution system for international disputes.
The RETJ does not prescribe a single contract model, but it does establish minimum requirements and limits that every contract must respect. Added to this is the labor legislation of the country where the contract is executed, which may add additional requirements.
Contract duration: FIFA limits
Art. 18, section 2, of the RETJ establishes clear rules on the duration:
| Rule | Duration | Detail |
|---|---|---|
| Minimum duration | From the registration date until the end of the season | It cannot be less than this period. Ensures that the player is available for at least one full season. |
| Maximum duration | 5 years | Longer contracts are only permitted if they comply with the national legislation of the relevant country. |
| Under 18 years of age | Maximum 3 years | No longer period clause is accepted. Special protection for young players. |
The 3-year rule for minors is strict: any clause that extends the contract beyond that limit isnull. This includes the so-called "extension options" that some clubs include to secure the player beyond the age of majority. If the option results in a total period greater than 3 years, the clause is not recognized.
Structure of a contract: what it should include
The RETJ does not prescribe a standard format, but theAnnex 2(which regulates coaching contracts and serves as an analogical reference) lists the essential elements that every sports employment contract should contain. Applied to players, a complete contract should include:
Identification of the parties (club and player), object of the contract, rights and obligations of each party, duration (start and end dates), agreed remuneration (base salary, bonuses, bonuses), signatures of both parties.
Name, client and license number of the football agent (if involved), declaration on influence of third parties (art. 18bis), declaration on ownership of economic rights (art. 18ter), conditions of registration and status of the player.
Performance bonuses (goals, assists, games played), signing bonus, termination or buy-out clause, loan or transfer conditions, image rights, insurance, conduct obligations.
Clauses that matter: detailed analysis
Remuneration
Theremunerationis the central element of the contract and one of the criteria that defines the player's professional status. According to the definition of the RETJ (Agents Regulation), remuneration includesbase salary, payment upon signing and any amounts payable for compliance with conditions(bonuses for performance, loyalty, etc.).
Not included in the remuneration: compensation for future transfer agreed between clubs, nor non-financial compensation such as vehicle, accommodation or telephone.
Buy-out clause vs. compensation clause (liquidated damages)
This is one of the most important — and most misunderstood — distinctions in football contracts. According to the jurisprudence of the CAS, they are completely different things:
| Buy-out clause | Liquidated damages clause | |
|---|---|---|
| What is it | A pre-agreed right to terminate the contract by paying a predetermined sum | An amount contractually fixed as compensation for non-compliance |
| Legal nature | Terminationby mutual agreement(advance consent) | Breach of contractwith pre-agreed amount |
| Does it generate sports sanctions? | No—no breach | Yes, potentially—if the termination falls within the protected period |
| TAS criterion | The clause must expressly grant theright to terminatethe contract | The clause sets the amount of compensationin case of non-compliance |
The distinction matters a lot in practice. If a player exercises a buy-out clause, he is simply terminating the contract under previously agreed conditions: there is no breach, there are no sporting sanctions (no 4-month restriction for the player or no registration ban for the club).
If, however, the player terminates and pays an "agreed compensation", there is still a contractual breach, which may activate the sanctions of art. 17 of the RETJ if the termination occurs during the protected period.
The protected period: the invisible clause
Although it does not appear as a clause in the contract, theprotected periodis a concept that directly affects the consequences of any termination. It is defined in definition no. 7 of the RETJ:
- If the contract was signedbefore the age of 28of the player:3 full seasons or 3 yearsfrom entry into force (whichever occurs first).
- If signedafter 28 years of age: 2 full seasons or 2 years.
Terminating within the protected period implies automatic sporting sanctions:4 months restrictionto play (6 in aggravating cases) for the player, andprohibition of registering players for 2 windowsfor the offending club or for the new club that induced the non-compliance (art. 17, sections 3 and 4).
The protected period restarts when a contract is renewed by extending its duration.
Precontracts and freedom of negotiation
Art. 18, section 3 of the RETJ regulates when a player can start negotiating with another club:
A professional player has freedom ofsign a contract with another clubif your current contract has expired orwill expire within a period of 6 months. This enables so-called "pre-contracts" or preliminary agreements.
But there is a prior obligation: the club interested in hiring the player mustcommunicate its intention in writing to the current clubbefore starting negotiations. Violation of this provision generates sanctions.
A player in a Spanish club has a contract until June 30. As of January 1, any club can communicate its intention to the Spanish club, negotiate with the player and sign a pre-contract for him to join on July 1.
An Italian club directly contacts a Brazilian player who still has 8 months left on his contract, without informing the Brazilian club. Even if the player eventually transfers legally, the lack of prior communication can lead to disciplinary sanctions for the Italian club.
Double contracts: what happens if you sign two
If a professional player arrangesmore than one contract for the same period, the provisions of Chapter IV of the RETJ apply — that is, the rules on contractual stability and consequences of termination without justified cause (art. 18, section 5). In practice, the first contract takes precedence and the second can generate severe consequences.
What cannot condition the validity of the contract
Art. 18, section 4, of the RETJ is clear: the validity of a contractcannot be subordinateda:
- The positive results of amedical examination
- The granting of awork permit
This means that if a club signs a contract with a player and then the player fails the medical, the contract is still valid. The club cannot cancel it for that reason. The same logic applies to work permits: if permission is not granted, the club cannot use that as an excuse to ignore the contract.
Special protections for female players
The current RETJ includes significant protections for professional soccer players:
Maternity leave (art. 18, section 7):Players have the right to maternity leave, adoption leave and parental leave during the term of their contract. They will receive at leasttwo thirds of the salary. If a collective agreement or national legislation offers more favorable conditions, these prevail.
Protection against dismissal due to pregnancy (art. 18quater):If a club terminates the contract because the player is pregnant, on maternity leave, adoption leave or parental leave, it is considered terminationwithout justified cause. It is presumed that the termination was for these reasons (reversal of the burden of proof). The compensation includes the residual value of the contract plus6 additional monthly salaries.
Absolute prohibitions:The validity of a contract cannot be made subject to a pregnancy test or its results, nor to the fact that the player is or becomes pregnant.
How compensation is calculated when a contract is broken
Understanding how compensation for breach of contract is calculated is key to evaluating the risks of any contractual decision. The art. 17 of the RETJ establishes that compensation is calculated according to the principle of"positive interest", taking into account the damage suffered, the circumstances of the case and the legislation of the country.
| Situation | Calculation of compensation |
|---|---|
| The club terminates and the player does not have a new contract | Residual value of the terminated contract (what the player would have received until maturity) |
| The club terminates and the player has already signed a new contract | Residual value of the terminated contract less the value of the new contract during the remaining period ("reduced compensation"). If it was due to overdue debts: an additional compensation of 3 to 6 monthly salaries is added. |
| The player terminates without just cause | Compensation calculated according to the damage suffered by the club, considering: remuneration and benefits of the contract, remaining time (maximum 5 years), amortized transfer expenses, and whether the breakup was within the protected period. |
| There is an agreed compensation clause | The agreed amount applies, provided it is proportional and reciprocal. If it is not, the CAS may declare it void and apply the general criteria of art. 17. |
The player's new club can besolidarity responsibleof the payment of compensation if it induced the player to breach his contract (art. 17, section 2).
The 10 most common mistakes when signing a contract
- Not reading the entire contract before signing.It seems obvious, but it is the most common error. Each clause has legal and economic consequences.
- Do not verify the duration.Signing for more than 3 years while under 18 generates a void clause. Sign for more than 5 years without national legal support as well.
- Do not detail the complete remuneration.If the contract says "salary to be agreed" or does not specify the exact amount of the base salary and bonuses, it is a serious problem in any dispute.
- Accept grace period clauses.Clauses that give the club extra time to pay are not recognized by FIFA (art. 18, section 6). If your salary is delayed for 2 months, you have justified cause to leave.
- Do not distinguish between buy-out and liquidated damages.If your clause says "indemnification" instead of "right to terminate", there may be sporting sanctions when exercising it.
- Make validity conditional on the medical examination.If the contract says "subject to satisfactory medical examination", that condition is not valid under art. 18, section 4 of the RETJ.
- Do not include the agent's data.The omission of the name, license number and signature of the agent may generate validity problems (art. 18, section 1).
- Sign without advice.A football contract involves labor law, international sports law and tax regulation. It's not something to solve alone.
- Do not keep a signed copy of the contract.In the event of a dispute, the burden of proof falls on the person who alleges it. Without a signed contract, there is no proof.
- Sign a second contract without resolving the first.If you sign with another club while you have a current contract, the rules of art. 17 with all its consequences: compensation, sporting sanctions and joint liability of the new club.
What to do before signing: checklist for players
Is it appropriate for your age? Does it respect the 3-year limit if you are a minor? Does the maximum of 5 years comply with the country's legislation?
Are the base salary, bonuses and signing bonus detailed? Are premium payment conditions measurable and verifiable?
Is there a termination clause? Is it a buy-out (right to terminate) or an indemnity (compensation for non-compliance)? Is the amount proportional?
A sports lawyer who knows both the RETJ and local labor laws can save you years of problems. The investment is worth it.
