GNC Franchising, Inc., challenges the district court’s refusal to enforce a forum selection clause in its franchise agreement with Charles B. Jones. The company contends that the court erred in denying its motion to either dismiss or transfer venue under 28 U.S.C. §§ 1404 and 1406. For the reasons assigned, we affirm.

BACKGROUND

GNC, a subsidiary of General Nutrition Companies, Inc., is franchisor of General Nutrition Stores throughout the United States. The company’s principal place of business is Pittsburgh, Pennsylvania. Jones is the franchisee of a GNC store in LaVerne, California.

In January 1995 and August 1996, the parties entered into written agreements, including an Option Agreement and a Franchise Agreement, for Jones’ store. Each agreement contains a choice of law clause requiring that it be “interpreted and construed under the laws of the Commonwealth of Pennsylvania, which laws shall prevail in the event of any conflict of law.” Both agreements also contain a forum selection clause providing that any action instituted by a franchisee against GNC “in any court, whether federal or state, shall be brought only within the Commonwealth of Pennsylvania in the judicial district in which Franchisor has its principal place of business; and the parties waive all questions of personal jurisdiction or venue for the purpose of carrying out this provision.”

A dispute about the agreements arose and Jones filed suit in California state court alleging multiple causes of action. 2 GNC timely removed the litigation to federal court, invoking diversity jurisdiction. 3 The company subsequently moved to either dismiss or transfer venue to the Western District of Pennsylvania, citing 28 U.S.C. § 1406 (a). 4 Alternatively, GNC *497 sought a transfer of venue under 28 U.S.C. § 1404 (a). 5

After considering the motions and Jones’ response, the district court denied the motion to dismiss or transfer under § 1406(a), concluding that the forum selection clause was unenforceable because it contravened California’s strong public policy against such provisions. The court also denied the motion to transfer under § 1404(a) after weighing the relevant factors under the requisite “interest of justice” analysis.

GNC petitioned for permission to appeal the district court’s decision, citing 28 U.S.C. § 1292 (b) and Federal Rule of Appellate Procedure 5. Permission was granted.

ANALYSIS

I. Enforcement of the Forum Selection Clause under § 1406

In diversity cases, federal law governs the analysis of the effect and scope of forum selection clauses. 6 We have held that the rule set forth by the Supreme Court in M/S Bremen v. Zapata Off-Shore Co. 7 controls the consideration of a motion to dismiss for improper venue based upon a forum selection clause. 8

In Bremen, the Supreme Court held that a forum selection clause is presumptively valid and should not be set aside unless the party challenging the clause “clearly show[s] that enforcement would be unreasonable and unjust, or that the clause was invalid for such reasons as fraud or overreaching.” 9 The court added, however, that a contractual forum selection clause is “unenforceable if enforcement would contravene a strong public policy of the forum in which suit is brought, whether declared by statute or by judicial decision.” 10 Moreover, even though a clause is the product of a full and free bargaining process, and contravenes no public policy of the forum, it “may nevertheless be ‘unreasonable’ and unenforceable if the chosen forum is seriously inconvenient for the trial of the action.” 11 The party challenging the forum selection clause bears a “heavy burden” of establishing the existence of one of the aforementioned grounds for rejecting its enforcement. 12

The district court declined to enforce the parties’ contractual forum selection clause, concluding that it contravened California’s strong public policy against enforcing such clauses in franchise agreements, as expressed in § 20040.5 of the California Business and Professions Code. Section 20040.5 provides that “[a] provision in a franchise agreement restricting venue to a forum outside this state is void with respect to any claim arising under or relating to a franchise agreement involving a franchise business operating within this state.” 13 The forum selection clause at bar would restrict venue to Pennsylvania courts. It is apparent that § 20040.5 is *498 intended to void this clause with respect to any claim arising under or relating to the agreement involving the franchise located in LaVerne, California. GNC, however, contends that the district court erred in concluding that the California statute embodies a strong public policy interest precluding enforcement of the clause under federal law.

We find this contention to be without merit. Bremen teaches that a strong public policy may be “declared by statute.” 14 By voiding any clause in a franchise agreement limiting venue to a non-California forum for claims arising under or relating to a franchise located in the ■ state, § 20040.5 ensures that California franchisees may litigate disputes regarding their franchise agreement in California courts. 15 We conclude and hold that § 20040.5 expresses a strong public policy of the State of California to protect California franchisees from the expense, inconvenience, and possible prejudice of litigating in a non-California venue. A provision, therefore, that requires a California franchisee to resolve claims related to the franchise agreement in a non-California court directly contravenes this strong public policy and is unenforceable under the directives of Bremen. Accordingly, we affirm the district court’s order denying GNC’s motion to dismiss or transfer the action under § 1406(a).

II. Transfer of Venue under § 1404(a)

GNC also claims error in the district court’s denial of its motion to transfer venue to the Western District of Pennsylvania under the provisions of § 1404(a). We review that order for abuse of discretion. 16

Under § 1404(a), the district court has discretion “to adjudicate motions for transfer according to an ‘individualized, case-by-case consideration of convenience and fairness.’ ” 17 A motion to transfer venue under § 1404(a) requires the court to weigh multiple factors in its determination whether transfer is appropriate in a particular case. 18 For example, the court may consider: (1) the location where the relevant agreements were negotiated and executed, (2) the state that is most familiar with the governing law, (3) the plaintiffs choice of forum, (4) the respective parties’ contacts with the forum, (5) the contacts relating to the plaintiffs cause of action in the chosen forum, (6) the differences in the *499 costs of litigation in the two forums, (7) the availability of compulsory process to compel attendance of unwilling non-party witnesses, and (8) the ease of access to sources of proof. 19 Additionally, the presence of a forum selection clause is a “significant factor” in the court’s § 1404(a) analysis. 20 We also conclude that the relevant public policy of the forum state, if any, is at least as significant a factor in the § 1404(a) balancing. 21

The district court weighed each of the aforementioned factors and concluded that GNC failed to meet its burden of showing that Pennsylvania was the more appropriate forum for the action. 22 Although the forum selection clause designates Pennsylvania as the exclusive forum, the court determined that other factors “clearly” demonstrated that California was more appropriate. For example, the court found that the vast majority of the other agreements underlying Jones’ claims were negotiated and executed in California. The court noted that Jones chose California as the forum for his lawsuit, and his choice is supported by California’s strong public policy to provide a protective local forum for local franchisees. The court further found that the extent of the parties’ contacts with Pennsylvania and California clearly favored California, and that Jones’ claims arose out of the construction and initial operation of the store located in LaVerne, California. The court also concluded that the relative financial burdens of litigating in each of the forums favored California. Finally, the court noted that more of the relevant witnesses and other sources of proof were located in California. Review of the relevant law and record on appeal persuades us that the trial court did not abuse its discretion in denying the motion to transfer venue under § 1404(a).

The judgment appealed is, in all respects, AFFIRMED.

. Jones’ claims include: (1) breach of written contract, (2) negligence, (3) breach of the covenant of good faith and fair dealing, (4) selling franchises by means of untrue or misleading statements, (5) intentional misrepresentation of fact, (6) negligent misrepresentation of fact, and (7) intentional interference with contractual relations.

. The district court sua sponte remanded the action to state court based upon lack of diversity jurisdiction after GNC’s initial removal attempt. Upon GNC's second attempt at removal, the court determined that it had diversity jurisdiction.

A forum selection clause, however, is not dispositive. Id. at 31, 108 S.Ct. 2239 .

. Although the majority opinion in Stewart did not expressly state that the law of the forum is a relevant factor for consideration under § 1404(a), the Court noted that the district court must weigh "those public-interest factors of systemic integrity and fairness that ... come under the heading of 'the interest of justice.’ ” Id. at 30, 108 S.Ct. 2239 . In a concurring opinion, Justice Kennedy and Justice O’Connor recognized that "state policies should be weighed in the balance.” Id. at 33 , 108 S.Ct. 2239 . We conclude that the public policy of the forum is not dispositive in a § 1404(a) determination but, rather, it is another factor that should be weighed in the court’s § 1404(a) "interest of justice” analysis.

.Under the doctrine of forum non conve-niens, GNC bears the burden of proving that an adequate alternative forum exists. Cheng v. Boeing Co., 708 F.2d 1406, 1411 (9th Cir.), cert. denied, 464 U.S. 1017 , 104 S.Ct. 549 , 78 L.Ed.2d 723 (1983).
