The NFL and NBA get the attention because their players have done it in public. The other leagues' agreements say the same thing, sometimes more plainly, and in soccer the worldwide regulations go further than any American union: they void a clause that punishes a player for negotiating alone. This page gives each league's rule from its own text, the fee cap where there is one, and what certification each requires. The NFL and NBA have their own pages.
NHL
The rule. NHL CBA Article 6.1: clubs "may not engage in negotiations for a Player's individual SPC with any person other than the Player or an agent certified by the NHLPA." Article 6.2: no contract is registered unless the player had a certified agent or, "if Player has no Certified Agent, acts on his own behalf." The text read is the 2012-2022 agreement; the 2025 extension was not checked.
The fee. No NHLPA cap was found in published text. Four to five percent is reported as typical, from secondary sources.
Certification. The NHLPA's FAQ says an applicant submits education, background and business history, and that about 200 agents are certified.
Cases. None documented well enough to list; a forum claim about one player was not substantiated.
MLB
The rule. The Basic Agreement keeps each player's right to negotiate individually above the minimums, and the MLBPA's regulations govern agents, not players. No clause worded like the NFL's or NBA's "acts on his own behalf" was found, which means the right is structural rather than spelled out: a player who negotiates his own contract is not using an agent, and the regulations bind only those who are.
The fee. No percentage cap. Section 6(I) of the regulations, as amended in 2019 with a 2023 memo, says no fee may be charged unless the negotiated salary exceeds the applicable minimum; no fee may bring net salary to the minimum or below; bonuses count only if earned; nothing on postseason pools, bargained allowances, group licensing or, since 2023, the pre-arbitration bonus pool. The agent invoices within 120 days of the season's end or forfeits the fee.
Certification. No degree requirement for general certification; a $2,500 application fee; an open-book written exam; an applicant is not certified until at least one major league player designates them, within four years of passing. Renewal is $1,500 for general certification, $500 for minor league or limited.
Cases. None documented.
WNBA
The rule. The WNBPA Regulations Governing Player Agents, § 1A: "No person (other than a player representing herself)" may negotiate without certification; the CBA language they quote has the league sign a contract when the player has a certified agent or "acts on her own behalf."
The fee. 5% of compensation actually received (base salary, signing bonus, earned performance bonus), and 5% on WNBA league or team marketing agreements. The regulations read are dated 2000; whether the 2026 CBA changed them was not confirmed.
Certification. A degree from an accredited four-year college, with experience accepted as a substitute.
MLS
The rule. The MLS and MLSPA CBA (February 2020 to January 2028), § 1.1: players may bargain "acting individually or through a player-agent." § 18.3(i): "A Player, if he so desires, may designate an agent." Certification applies only "if the MLSPA develops and implements an agent certification program"; players joining from or leaving for another league may use an agent the MLSPA has not certified.
The fee. A 10% figure in the standard player agreement was reported in September 2026 but not found in the CBA text, so it is not stated here as fact.
NWSL
The rule. The NWSL CBA (July 2024 to December 2030), § 7.2: "A player may designate a Player-Agent," and contracts "should specify the Player-Agent's ... FIFA license number." Certification is "within the purview of the NWSLPA" after consulting the league; no program was found in place. Dual representation is banned from 2026, and the league "may compensate a player Player-Agent up to ... ten percent (10%)"; agent fees count against the team salary cap.
Soccer worldwide: FIFA
The rule. The FIFA Football Agent Regulations, approved December 2024 and in force from January 1, 2025, Article 18(1)(a): clients "may engage a Football Agent ... provided that they do not choose to undertake such activities themselves." Article 12(13): any clause that limits or penalizes a player who negotiates "autonomously ... without the involvement of a Football Agent" is "null and void." No American union goes that far in writing.
The fee. Article 15 caps fees at 5% of remuneration up to $200,000 a year and 3% above it, 10% and 6% for dual representation. FIFA suspended the cap worldwide on December 30, 2023 pending litigation. On July 16, 2026 the Court of Justice of the European Union (C-209/23) held the cap is not a restriction of competition "by object" and sent the question of proportionality back to the Landgericht Mainz. Whether the cap is enforced in a given country today is unclear.
The licence. USD 600 a year. FIFA's FAQ, updated January 2025, says there is no professional exemption, even for lawyers: anyone who acts as an agent holds the licence.
What the set shows
Three things hold across every league above. The player's right to negotiate alone is written into the agreement, or structural where it is not spelled out. The thing no league allows is an uncertified intermediary, whoever they are. And the fee caps, where they exist, are low on the playing contract and absent on marketing, which is the pattern the fees page lays out. What the set lacks is a public record: the research found no documented self-negotiated contract in the NHL, MLB, WNBA, MLS or NWSL. That is not evidence it does not happen; it is evidence that when it does, nobody reports it.
How Leave fits
Leave is software for the athlete who handles the business side themselves, in any sport and at any level. It explains each contract in plain words with the money and the dates laid out, keeps deadlines on a countdown, and holds every deal in one record. It takes 0% from the athlete and does not negotiate, represent or sign for anyone. In every league above the player or a certified agent speaks to the club; Leave is what the player reads first.
Questions athletes ask
Can an NHL player negotiate his own contract?
Yes. NHL CBA Article 6.1 says clubs may not negotiate a player's contract "with any person other than the Player or an agent certified by the NHLPA," and Article 6.2 says a contract is registered when the player had a certified agent or, with none, "acts on his own behalf." No NHLPA fee cap was found in published text; 4 to 5% is reported as typical, and the NHLPA lists about 200 certified agents.
Can an MLB player negotiate his own contract?
Yes. The Basic Agreement preserves each player's right to negotiate individually above the minimum salary, and the MLBPA's regulations govern agents, not players. There is no percentage cap; the regulations bar any fee unless the negotiated salary is above the minimum and any fee that takes net pay to the minimum or below, with nothing on postseason pools or group licensing. No clause worded like the NFL's "acts on his own behalf" was found, and no documented self-negotiated MLB contract was found.
Can a WNBA player negotiate her own contract?
Yes. The WNBPA Regulations Governing Player Agents say no person "other than a player representing herself" may negotiate without certification, and the CBA language they quote has the league sign a contract when the player has a certified agent or "acts on her own behalf." The fee cap is 5% of compensation actually received, and 5% on WNBA league or team marketing agreements. The regulations read were dated 2000; a newer version was not found.
What about MLS and the NWSL?
MLS's CBA (2020 to 2028) says players bargain "acting individually or through a player-agent" and that a player "if he so desires, may designate an agent"; certification applies only if the MLSPA creates a program. The NWSL CBA (2024 to 2030) says "a player may designate a Player-Agent," puts certification within the NWSLPA's purview with no program found in place, lets the league compensate a player's agent up to 10%, and bans dual representation from 2026.
What do FIFA's rules say?
The FIFA Football Agent Regulations, in force from January 1, 2025, say a player "may engage a Football Agent ... provided that they do not choose to undertake such activities themselves," and that any clause limiting or penalizing a player who negotiates "autonomously ... without the involvement of a Football Agent" is "null and void." The fee cap, 5% of pay up to $200,000 a year and 3% above (10% and 6% for dual representation), was suspended worldwide in December 2023; in July 2026 the EU's top court held it is not a restriction "by object" and sent the proportionality question back to a German court.
Be your own agent. Leave.
