The sports sector is no longer just an area where sporting activities take place. It has become a comprehensive structure that generates high economic value and involves many contractual relationships and different legal rules at the same time. Professional athletes, sports clubs, federations, agents, sponsors, broadcasters, organisers, investors and fans are the different parties in this structure.

As sporting activities have grown in economic scale, the scope of sports law has also widened. Athlete contracts, transfers, sponsorship agreements, broadcasting rights, disciplinary proceedings, intellectual property, advertising relationships, athletes’ image rights, doping disputes and international sports arbitration make up a large part of the legal work in this area.

For this reason, sports law should be assessed at the intersection of different fields of law such as contract law, commercial law, employment law, intellectual property law, competition law, personal data protection, tax law, disciplinary law and international law.

Athlete, Transfer and Agency Contracts

Athlete Contracts and Professional Relationships

Setting up the legal framework of the relationship between a professional athlete and a club correctly is one of the fundamental issues in the sports sector. Unlike ordinary service contracts, athlete contracts are assessed together with federation regulations, sporting rules and transfer systems.

A professional athlete contract may regulate not only pay and the contract term but also many other elements, such as sporting performance, the bonus system, the use of kit and equipment, advertising obligations, medical checks, the provisions that apply in the event of injury, disciplinary obligations and the conditions for termination of the contract.

The following issues may be particularly important in athlete contracts:

Contract term and renewal conditions
Fixed salary, bonuses and performance bonuses
Transfer and release clauses
Injuries and medical checks
Sporting and disciplinary obligations
Participation in advertising and sponsorship activities
Image and likeness rights
Termination of the contract and its consequences
Dispute resolution method

Because an athlete’s professional career is short and dependent on performance, it is important to assess contracts in a way that takes into account not only the current season but also the athlete’s career planning.

Transfer Processes and Transfer Agreements

In professional sport, transfers can have significant economic consequences. Especially in football, basketball and other high-budget sports, a transfer is not just a contract between the athlete and the new club.

A single transfer may involve several different legal relationships, such as the termination of the contract with the current club, the transfer compensation (bonservis bedeli), transfer fees, performance-related add-ons, sell-on clauses and agent commissions.

In international transfers, federation regulations, foreign player status, work permits, the payment currency, international tax issues and foreign law elements may also come into play.

Because transfer agreements have high financial stakes, clearly defining the parties’ rights and obligations is important to prevent receivables or breach of contract disputes that may arise later.

Sports Agency and Representation Contracts

Sports agents may play an important role in managing athletes’ relationships with clubs, sponsors and other commercial parties. The scope of the legal relationship between the agent and the athlete should be set out in a written representation or agency contract.

Agency contracts should clearly regulate matters such as:

The scope of the authority to represent
The commission rate
The contract term
Exclusivity clauses
Powers in transfer negotiations
The agent’s role in sponsorship and advertising deals
Coverage of expenses
Termination of the contract

These issues need to be addressed explicitly.

Situations such as an athlete working with more than one representative at the same time, the limits of the authority to represent, or a commission being claimed even though no transfer took place can lead to disputes in agency relationships.

Sponsorship, Image and Broadcasting Rights

Sponsorship and Advertising Agreements

The high viewing figures of sport and its reach to wide audiences have made sponsorship agreements one of the most important sources of income in the sector. Sports clubs, federations, events and individual athletes may enter into sponsorship relationships with different brands.

Sponsorship agreements may regulate where the brand will be used, the visibility the sponsor will obtain, the athlete’s or club’s participation in advertising activities, social media posts, kit and in-stadium advertising, and attendance at events.

In athlete sponsorships in particular, category conflicts between different brands may arise. When an athlete enters into sponsorship relationships with two companies operating in the same product group, exclusivity clauses become important.

It is also important for the agreements to regulate matters such as conduct that may affect the reputation of the athlete or club, early termination of the campaign, the use of advertising materials, and how long existing content may be used after the agreement ends.

Athletes’ Image, Name and Likeness Rights

Today, the economic value of professional athletes does not come only from sporting performance; their name, photograph, voice, signature, shirt number and personal brand elements can also carry significant commercial value.

Where an athlete’s image is used in an advertising campaign, a video game, social media content, a promotional item or a commercial product, the scope of the right of use needs to be clearly defined.

In image rights agreements, the duration of use, the countries where the image may be used, the media channels, the scope of the campaign, the right of re-use and the status of existing content after the agreement ends are particularly important.

Unauthorised use of a name or image may have different legal consequences under personality rights, intellectual property and unfair competition rules.

Broadcasting Rights and Sports Media

A large part of the economic value of professional sports events comes from television and digital broadcasting rights. The broadcasting rights of leagues, tournaments and individual sports events are often the subject of high-value commercial contracts.

Broadcasting rights agreements may regulate matters such as:

The matches that may be broadcast
Live and delayed broadcasting rights
Digital broadcasting rights
Mobile and social media usage rights
Geographical broadcasting limits
Use of highlights
The right to grant sub-licences
Sharing of advertising revenue

These matters can all be covered in the agreement.

As digital platforms have entered sports broadcasting, it has become increasingly important to regulate broadcasting rights separately for the internet, mobile applications and social media.

Clubs, Federations and Sports Arbitration

Corporate and Commercial Structure of Sports Clubs

The legal structure of sports clubs is not limited to sporting activities. Professional clubs carry out many economic activities, such as transfers, sponsorship, sales of licensed merchandise, broadcasting revenue, facility management and commercial partnerships.

For this reason, company law and corporate governance issues are important for clubs. The limits of management powers, company structures, sponsorship and commercial contracts, borrowing, investments and the legal framework of transactions with third parties need to be set up correctly.

Clubs’ relationships with their subsidiaries, sports companies and investors may also require separate legal arrangements.

Sports Federations and Disciplinary Law

Sporting activities have their own specific rules, and these rules are usually set by the relevant federations. Athletes, clubs, officials and other sports stakeholders must act in accordance with federation regulations.

Disciplinary proceedings may involve sporting conduct, match incidents, licence violations, penalties, match bans or sanctions imposed on clubs.

The legal nature of disciplinary decisions, the right of defence, deadlines for objections and available remedies should be assessed separately according to the federation regulations of each sport.

Doping Disputes and Athletes’ Rights

Doping control is one of the important regulatory areas of professional sport. Athletes have obligations regarding prohibited substances and methods, while the conduct of doping tests and the evaluation of their results are also subject to specific procedures.

In doping disputes, many factors may be assessed, such as how the sample was taken, laboratory procedures, how the prohibited substance came to be used, the athlete’s fault and the proportionality of the sanction that may be imposed.

The medicines used by the athlete, the information given by the medical team and therapeutic use exemptions may also be important in some disputes.

In these proceedings, not only sporting regulations but also the athlete’s right of defence and the principles of a fair trial must be taken into account.

International Sports Law and Sports Arbitration

The international nature of professional sport has led to the development of a special legal system in which disputes are not resolved only before national courts.

While international sports federations apply their own regulations, some sports disputes may be brought before international arbitration mechanisms. In particular, CAS (Court of Arbitration for Sport / Spor Tahkim Mahkemesi) is one of the main dispute resolution mechanisms in international sports law.

In international transfers, doping sanctions, federation decisions and some contractual sports disputes, it is important to determine the applicable law and the available remedies correctly at the outset.

Events, Facilities and Esports

Sports Events and Event Contracts

Organising tournaments, races, marathons, championships or private sports events can give rise to many contractual relationships.

Different contracts may be concluded between the organiser and athletes, facility operators, sponsors, security companies, broadcasters, ticketing companies and suppliers.

In event contracts, provisions on cancellation and postponement, weather conditions, security measures, participant liability, insurance, ticket refunds and force majeure are important.

Especially at large events, cancelling an event may affect not only relationships with spectators but also sponsorship, broadcasting, accommodation and logistics contracts at the same time.

Sports Facilities and Real Estate Law

Stadiums, sports halls, training grounds, tennis courts, golf facilities and other sports venues may give rise to separate legal relationships in terms of real estate and facility management.

The purchase, lease, transfer of operating rights or use of facilities by third parties may be carried out through different contracts.

Issues such as spectator safety, facility maintenance obligations, damage that third parties may suffer and the operator’s liability may also arise at sports facilities.

Esports and the Digital Sports Economy

The professionalisation of esports has created a new area where sports law intersects with technology law. Different contractual relationships are being formed between professional esports players, teams, game developers, tournament organisers, broadcasters and sponsors.

In esports, issues such as:

Player contracts
Team and transfer relationships
Tournament participation agreements
Broadcasting and streaming rights
Sponsorship agreements
The game developer’s intellectual property rights
Use of digital content
Personal data protection

may require legal assessment.

In the esports ecosystem, the intellectual property rights in the game are usually controlled by a private company, which creates a legal structure different from that of traditional sports events.

Sports Technology, Data and Brands

Sports Technology, Data Analytics and Artificial Intelligence

Professional sports clubs and athletes are increasingly using technological systems for performance analysis. Wearable devices, GPS tracking systems, biometric sensors, AI-assisted performance analysis and injury prediction systems generate large amounts of data.

Since some of this data may relate to the athlete’s health or biometric information, it may require a specific assessment in terms of personal data protection.

It is important to clearly regulate who may use athlete performance data, whether it may be transferred to other clubs, whether it may be retained after the contract ends, and its use in commercial analysis systems.

AI-assisted scouting and transfer systems are also becoming more widespread in the sports sector, and the use of algorithms in decision-making is raising new legal questions regarding data security, discrimination and automated decision-making.

Personal Data Protection in the Sports Sector

Sports clubs and organisations may process a significant amount of personal data about athletes, employees, fans and members. In addition to identity and contact details, this may include health data, performance information, membership records, ticketing data and camera footage.

The processing of athletes’ health and biometric information in particular may require a more careful assessment under the Law on the Protection of Personal Data No. 6698 (KVKK).

In ticketing and fan systems, it should be clearly defined for what purposes user information is collected, whether it is used for marketing and whether it is shared with third parties.

Sports Brands and Licensed Products

Club crests, team names, tournament logos and athlete brands may carry significant commercial value. The manufacture and sale of shirts, accessories and other licensed products require the protection of trademark and intellectual property rights.

Licence agreements may regulate matters such as which products the manufacturer may produce, in which territories it may use the brand, sales channels, quality standards and the licence fee.

Infringements such as the sale of counterfeit shirts and unlicensed products may be assessed separately under trademark, unfair competition and intellectual property rules.

Employment Law in the Sports Sector

Employment relationships in the sports sector are not limited to professional athletes. Head coaches, coaches, medical staff, administrative employees, facility staff and event staff may work under different employment contracts.

Working hours, bonus systems, seasonal work, termination of employment contracts and employees’ confidentiality obligations may require specific arrangements depending on the nature of the sector.

Where technical staff move to rival clubs, the protection of trade secrets and the club’s strategic information may also be addressed separately in the contracts.

Determining the Legal Route in Sports Disputes

An important feature of sports disputes is that not every dispute can be resolved in the ordinary courts. Federations’ own boards, arbitration boards and international sports arbitration mechanisms may have special jurisdiction over certain disputes.

For this reason, in a sports dispute the first step is to determine which body has jurisdiction, the deadline for applying and the applicable rules. Short deadlines make this especially important in some sports disputes.

Transfer agreements, athletes’ receivables, disciplinary penalties, sponsorship disputes, broadcasting rights and commercial contracts may be subject to different dispute resolution mechanisms.

Legal Advice in the Sports Sector

Building an effective legal structure in sports law is not only about resolving disputes once they arise. At every stage, from drafting an athlete contract to a club’s sponsorship model, and from a transfer to the licensing of broadcasting rights, it is important to align economic and sporting goals with the legal structure.

Attorney Ezgi Çalışkan assesses legal matters in the sports sector within the framework of sports law, contract law, commercial law, intellectual property law, IT and technology law, personal data protection and international law.

Athlete and agency contracts, transfer processes, sponsorship agreements, image rights, broadcasting rights, relationships with sports federations, disciplinary and doping disputes, esports, sports technology, the use of digital data and international sports arbitration are among the main legal issues that can be addressed in this context.

Today, as sport becomes increasingly intertwined with competition, technology and global capital, a sound legal framework helps athletes, clubs and commercial players in the sector to structure their long-term decisions in a more predictable and sustainable way.
