delivered the opinion of the Court.
This is the appeal of two negligence cases. In each case a joint tort-feasor had been released by the plaintiffs. Subsequently, the trial court refused to apply the 1979 covenant-not-to-sue statute and ruled that the other joint wrongdoer also had been released. The sole question is whether the statute affects substantive rights of joint tort-feasors or merely impacts procedural aspects of their remedy.
In October of 1977, a motor vehicle operated by appellant Mary W. Shiflet, in which appellant Harvey H. Shiflet, III was a passenger, was in a collision with two other motor vehicles in the City of Virginia Beach. The other vehicles were operated by Everette F. Horton and appellee Murray L. Eller. In separate damage suits filed in 1979, the Shiflets sued Horton and Eller seeking judgments against the defendants jointly and severally. The plaintiffs asserted the defendants were guilty of simple negligence that proximately caused their injuries.
Effective July 1, 1979, the General Assembly enacted Code § 8.01-35.1, the statute in question. Acts 1979, ch. 697. 1
*118 In May of 1981, the Shiflets settled their respective claims with defendant Horton, executing separate documents labelled “Release or Covenant Not To Sue Agreement Pursuant to Virginia Code Section 8.01-35.1, As Amended.” These documents discharged Horton from further liability to the Shiflets and purported to reserve all claims or rights that the Shiflets had against Eller. Thereafter, the trial court sustained pleas of release filed by Eller and dismissed with prejudice the plaintiffs’ suits against him. We awarded the plaintiffs appeals from the September 1981 final orders and consolidated the cases; for clarity, we will treat them as one.
The plaintiff contends the trial court’s ruling that the release of one joint tort-feasor released both ignored the provisions of the statute in question and the terms of the release document, which was drawn in strict compliance with the statute. The court below erred, the plaintiff argues, in refusing to apply the 1979 statute to *119 the 1981 release document, even though the plaintiffs cause of action for damages arose in 1977.
The plaintiff admits that prior to the 1979 enactment of Code § 8.01-35.1, the release of one joint wrongdoer released all joint tort-feasors.
Wright
v.
Orlowski,
The plaintiff contends that when the foregoing principles are applied to the present case, application of the 1979 covenant-not-to-sue statute to the 1981 transaction does not “disturb Eller’s so-called vested right of discharge.” According to the plaintiff, until such time as payment or settlement by a joint tort-feasor has been made, the discharge of Eller remains a mere possibility, contingent on a future event, and therefore cannot be considered vested.
Analogizing to
Walke
v.
Dallas, Inc.,
*120 The defendant Eller contends that the plaintiff erroneously dwells on the existence of a “vested” right instead of properly focusing on the presence of a “substantive” right. He argues that the proper analysis is simply to determine whether or not a right of contribution, regardless of when it ripens, involves substantive or procedural rights. Eller argues that if any substantive right is involved, “then any statute affecting that right cannot be applied retroactively to a cause of action which accrued prior to enactment of” the statute in question. He contends the trial court properly decided, in the court’s language, “that the substantive rights of the participants were determined in 1977, when this cause of action arose.” Thus, Eller concludes, the trial court correctly applied the 1977 law to the 1977 cause of action and decided that the release of one joint wrongdoer released the other. We agree with Eller.
Preliminarily, we observe that “substantive” rights, as well as “vested” rights, are included within those interests protected from retroactive application of statutes. The concept of protection of substantive rights was incorporated by the General Assembly into Virginia civil procedure with the enactment of Title 8.01, effective October 1, 1977. Specifically, § 8.01-1 provides for retroactive application of all provisions of the Title, unless a particular provision “may materially change the substantive rights of a party (as distinguished from the procedural aspects of the remedy) . . . .” Substantive rights, which are not necessarily synonymous with vested rights, are included within that part of the law dealing with creation of duties, rights, and obligations, as opposed to procedural or remedial law, which prescribes methods of obtaining redress or enforcement of rights. Black’s Law Dictionary 1281 (5th ed. 1979). “While all vested rights may be considered substantive ... it does not necessarily follow that the only subject matter that is considered to be substantive is that which relates to vested rights.”
Joseph
v.
Lowery,
Next, we must determine the nature of the right of contribution and when it comes into existence, keeping in mind the difference between a cause of action and a right of action. A right of action is a remedial right to presently enforce a cause of action; operative facts giving rise to a right of action comprise a cause of action.
First Virginia Bank-Colonial
v.
Baker, 225
Va. 72, 81,
In the case of contribution, the cause of action and the right of action do not arise at the same time. “[T]here is a valid distinction between the accrual of the equitable,
inchoate
right to contribution that arises at the time of jointly negligent acts and the maturation of the right to
recover
contribution that arises only after payment of an unequally large share of the common obligation.”
Nationwide Mutual Insurance Co.
v.
Minnifield,
Because the cause of action for contribution accruing to Eller, a joint tort-feasor, arose at the time of the jointly negligent acts in October of 1977, it necessarily follows that the 1979 statute in question, which adversely affects that substantive right, cannot be applied retroactively to impair that right.
Carickhoff
v.
Badger-Northland, Inc.,
The plaintiff has referred us to cases from other jurisdictions to support the view that no vested or substantive right accrued to Eller before enactment of the statute in question. They are inapposite and we will address only the one upon which principal reliance is placed.-

Notes
Code § 8.01-35.1 presently provides:
“Effect of release or covenant not to sue in respect to liability and contribution. —
*118 A. When a release or a covenant not to sue is given in good faith to one of two or more persons liable in tort for the same injury, or the same property damage or the same wrongful death:
1. It shall not discharge any of the other tort-feasors from liability for the injury, property damage or wrongful death unless its terms so provide; but any amount recovered against the other tort-feasors or any one of them shall be reduced by any amount stipulated by the covenant or the release, or in the amount of the consideration paid for it, whichever is the greater. A release or covenant not to sue given pursuant to this section shall not be admitted into evidence in the trial of the matter but shall be considered by the court in determining the amount for which judgment shall be entered; and
2. It shall discharge the tort-feasor to whom it is given from all liability for contribution to any other tort-feasor.
B. A tort-feasor who enters into a release or covenant not to sue with a claimant is not entitled to recover by way of contribution from another tort-feasor whose liability for the injury, property damage or wrongful death is not extinguished by the release or covenant not to sue, nor in respect to any amount paid by the tortfeasor which is in excess of what was reasonable.
C. A release or covenant not to sue given pursuant to this section shall be subject to the provisions of §§ 8.01-55 and 8.01-424.
D. This section shall apply to all such covenants not to sue executed on or after July 1, 1979, and to all releases executed on or after July 1, 1980, regardless of the date the causes of action affected thereby accrued.”
The original enactment did not refer to releases; references to such documents were added in subsequent years by Acts 1980, ch. 411 and Acts 1983, ch. 181.
The statutes designated in subsection (C) deal with compromises of wrongful death claims and compromises of actions in which persons under disability are parties.
Subsection (D) was added by a 1982 amendment. Acts 1982, ch. 196.
