Mr. Justice Stewart
delivered the opinion of the Court,
We here review the decisions of two three-judge federal District Courts that upheld thé constitutionality of Florida and Pennsylvania laws authorizing the summary seizure of goods or chattels in a person’s possession under a writ of replevin. Both statutes provide for the issuance of writs ordering state agents to seize a person’s possessions, simply upon the ex parte application of any other person who claims a right to them and posts a [70]*70security bond. Neither-statute provides for notice to be given to the possessor of the property, and neither statute gives the possessor an opportunity to challenge the seizure at any kind of prior hearing. The question is whether these statutory procedures violate the Fourteenth Amendment's guarantee that no State shall deprive any person of property, without due process of law.

The appellant in No. 5039, Margárita Fuentes, is a résident of Florida. She purchased a gas stove and service policy from the Firestone Tire and Rubber Co. (Firestone) under a conditional sales contract calling for monthly payments over a period of time. A few months later, she purchased a stefeophonic phonograph from the same company under the same sort of contract. The' total cost of the stove and stereo was about $500, plus an additional financing charge of over $100. Under the contracts, Firestone retained title to the merchandise, but Mrs. Fuentes was entitled to possession unless and until, she should default on her installment payments.
For more than a year, Mrs. Fuentes made her installment payments. But then, with only about $200 remaining to be paid, a dispute developed between her and Firestone over the servicing of the stove. Firestone instituted an action in a small-claims' court for repossession of both the stove and the stereo, claiming that Mrs. Fuentes had refused to make her remaining payments. Simultaneously with the filing of that action and before Mrs. Fuentes had even received a summons to answer its complaint, Firestone obtained a writ of replevin ordering a sheriff to seize the disputed goods at once.
In conformance with Florida procedure,1 Firestone [71]*71had only to fill in the blanks on the appropriate form documents and submit them to the clerk of the small-claims court. The clerk signed and stamped the documents and issued a writ of replevin. Later the same day, a local deputy sheriff and an agent of Firestone went to Mrs. Fuentes’ home and seized the stove and stereo.
Shortly thereafter, Mrs. Fuentes instituted the present action in a federal district court, challenging the constitutionality of the Florida prejudgment replevin procedures under the Due Process Clause of the Fourteenth Amendment.2 She sought declaratory and in-junctive relief against continued enforcement of the procedural provisions of the state statutes that authorize prejudgment replevin.3
The appellants in No. 5138 filed a very similar action in a federal district court in Pennsylvania, challenging the constitutionality of that State’s prejudgment re-plevin process. Like Mrs. Fuentes, they had had possessions seized under writs of replevin. Three of the appellants had purchased personal property — a bed, a table, and other household goods — under installment sales contracts like the one signed by Mrs. Fuentes; and the sellers of the property had obtained and executed summary writs of replevin, claiming that the appellants had fallen behind in their installment payments. [72]*72The experience of the fourth appellant, Rosa Washing'-'-' ton, had b.een more bizarre. She had been divorced from a local deputy sheriff and was engaged in a dispute with him over the custody of their son. Her former husband, being familiar with the routine forms used in the replevin process, had obtained a writ that ordered the seizure of the boy’s clothes, furniture, and toys.4
In both No. 5039 and No. 5138, three-judge District Courts were convened to consider the appellants’ challenges 'to the constitutional validity of the Florida and Pennsylvania statutes. The courts in both cases upheld the constitutionality of the statutes. Fuentes v. Faircloth, 317 F. Supp. 954 (SD Fla); Epps v. Cortese, 326 F. Supp. 127 (ED Pa.).5 We noted probable jurisdiction of both appeals. 401 U. S. 906; 402 U. S. 994.
[73]*73II
Under the Florida statute challenged here,6 “[a]ny person whose goods or chattels are wrongfully detained by any other person . . . may have a writ of replevin to recover them . . . Fla. Stat. Ann. § 78.01' (Supp. 1972-1973). There is no requirement that the applicant make a convincing showing before the seiz[74]*74ure that the goods are, in fact, “wrongfully detained.” Rather, Florida law automatically relies on the bare assertion of the party . seeking the writ that he is entitled to one and allows a court clerk to issue the writ summarily. It requires only that the applicant file a complaint, initiating a court action for repossession and reciting in conclusory fashion that he is “lawfully entitled to the possession” of the property, and that he file a security bond
“in at least double the value of the property to be replevied conditioned Ihat plaintiff will prosecute his action to effect and without delay and that if defendant recovers judgment against him in the action, he will return the property, if return thereof is adjudged, and will pay defendant all sums of money recovered, against plaintiff by defendant in the action.” Fla. Stat. Ann. § 78.07 (Supp. 1972-1973).
[75]*75On the sole basis of the complaint and bond,' a writ is issued “command [ing] the officer to whom it maybe directed to replevy the goods and chattels in possession of defendant. . . and to summon the defendant to answer the complaint.” Fla. Stat. Ann. § 78.08 (Supp. 1972-1973). If the goods'are “in any dwelling house or other building or enclosure,” the officer is required to demand their delivery; but, if they are not delivered, “he shall cause such house, building or enclosure to be broken open and shall make replevin according to the writ....” Fla. Stat. Ann. §78.10 (Supp. 1972-1973).
Thus, at the same moment that the defendant receives the complaint seeking .repossession of property through court action, the property is seized from him. He is provided no prior notice and allowed no opportunity whatever to challenge the issuance of the writ. After the property has been seized, he will eventually have an opportunity for a hearing, as the defendant in the trial of the court action for repossession, which the plaintiff is required to pursue. And he is also not wholly without recourse in the meantime. For under the Florida statute, the officer who seizes' the property must keep it for three days, and during that period the defendant may reclaim possession of the property by posting his own security bond in double its value. But if he does not post such a bond, the property is transferred to the party who sought the writ, pending a final judgment in the underlying action for repossession. Fla. Stat. Ann. §78.13 (Supp. 1972-1973).
The Pennsylvania law7 differs, though not in its essential nature, from that of Florida. As in Florida, [76]*76a private party may obtain a prejudgment writ of replevin through a summary process of ex parte application to a prothonotary. As' iii Florida, the party seeking [77]*77the.writ may simply post with his application a bond in double the value of the property to be seized. Pa. Rule Civ. Proc. 1073 (a). There is no opportunity for a prior hearing and no prior notice to the other party. On this basis, a sheriff is required to execute the writ by seizing the specified property. Unlike the Florida statute,- however, the Pennsylvania law does not require that there ever be opportunity for a hearing on the merits of the conflicting claims to possession of the replevied property. The party seeking the. writ is not obliged to initiate a court action for repossession.8 In[78]*78deed, he need not even formally allege that he is lawfully entitled to the property. The most that is required is that he file an “affidavit of the value of the property to be replevied.” Pa. Rule Civ. Proc. 1073 (a). If the party who loses property through replevin seizure is to get even a post-seizure hearing, he must initiate a lawsuit himself.9 He may also, as under Florida law, post his own eounterbond within three days after the seizure to regain possession. Pa. Rule Civ. Proc. 1076.

Although these prejudgment replevin statutes are descended from the common-law replevin action of six centuries ago, they bear very little resemblance to it. Replevin at common law was an action for the return of specific goods wrongfully taken or “distrained.” Typically, it was used after a landlord (the “distrainor”) had seized possessions from a tenant (the “distrainee”) to satisfy a debt allegedly owed. If the tenant then instituted a replevin action and 'posted security, the landlord could be ordered to return the property at [79]*79once, pending a final judgment in the underlying action.10 However, this prejudgment replevin of goods at common law did not follow from an entirely ex parte process of pleading by the distrainee. For “[t]he distrainor could always stop the action of replevin by claiming to be the owner of the goods; and as this claim was often made merely to delay the proceedings, the writ de proprietate probanda was devised early in the fourteenth century, which enabled the sheriff to determine summarily the question of ownership. If the question of ownership was determined against the distrainor the goods were delivered back to the distrainee [pending final judgment].” 3 W. Holdsworth, History of English Law 284 (.1927),
Prejudgment replevin statutes like those of Florida and Pennsylvania are derived from this ancient posses-sory action in that they authorize the seizure of property before a final judgment.. But the similarity ends there. As in the present cases, such statutes are most commonly used by creditors to seize goods allegedly wrongfully detained — not wrongfully taken — by debtors. At common law, if a creditor wished to invoke state power to recover goods wrongfully detained, .he had to proceed through the action of debt or detinue.11 These actions, however, did not provide for a return of property before final judgment.12 And, more importantly, on the occasions when the common law did allow prejudgment seizure by state power, it provided some kind [80]*80of notice and opportunity to be heard to the party then in possession of the property, and a state official made at least a summary determination of the relative rights of the disputing parties before stepping into the dispute and taking goods from one of them.
IY
For more than a century the central meaning of procedural due process has been clear: “Parties whose rights are to be affected are entitled to be heard; and in order that they may enjoy that right they must first be notified.” Baldwin v. Hale, 1 Wall. 223, 233. See Windsor v. McVeigh, 93 U. S. 274; Hovey v. Elliott, 167 U. S. 409; Grannis v. Ordean, 234 U. S. 385. It is equally fundamental that the right to notice and an opportunity to be heard “must be granted at a meaningful time and in a meaningful manner.” Armstrong v. Manzo, 380 U. S. 545, 552.
The primary question in the present cases is whether these state statutes are constitutionally defective in failing to provide for hearings “at a meaningful time.” The Florida replevin process guarantees an opportunity for a hearing after the seizure of goods, and the Pennsylvania process allows a post-seizure hearing if the aggrieved party shoulders the burden of initiating one. But neither the Florida nor the Pennsylvania statute provides for notice or an opportunity to be heard before the seizure, The issue is whether procedural due process in the context of these cases requires an opportunity .for a hearing before the State'authorizes its agents to seize property in the possession of a person upon the application of another.
The constitutional right to be heard is a b'asic aspect of the duty of government to follow a fair process of decisionmaking when it acts to deprive a person of his possessions. The purpose of this requirement is not [81]*81only to ensure abstract fair play to the individual. Its purpose, more particularly, is to protect his use and possession of property from arbitrary encroachment— to minimize substantively unfair or mistaken deprivations of property, a danger that, is especially great when the State seizes goods simply upon the application of and. for the benefit of a private party. So viewed, the prohibition against the deprivation of property without due process of law reflects the high value, embedded in our constitutional and political history, that we place on a person’s right to enjoy what is his, free of governmental interference. See Lynch v. Household, Finance Corp., 405 U. S. 538, 552.
The requirement of notice and an opportunity to be heard raises no impenetrable barrier to the taking of a person’s possessions. But thé fair process of decision-making that it guarantees works, by itself, to protect against arbitrary deprivation of property. For when a person has an opportunity to speak up in his own defense, and when the State must listen to what he has to say, substantively unfair and simply mistaken deprivations of property interests, can be prevented. It has long been recognized that “fairness can rarely be obtained by secret, one-sided determination of facts decisive of rights. .... [And n]o better instrument has been devised for arriving at truth than to give a person in jeopardy, of serious loss notice of the case against him and opportunity to meet it.” Joint Anti-Fascist Refugee Committee v. McGrath, 341 U. S. 123, 170-172 (Frankfurter, J., concurring).
If the right to notice and a hearing is to serve its full purpose, then, it is clear that it must be granted at a time when the deprivation can still be prevented. At a later hearing, an individual’s possessions can be returned to him if they were unfairly or mistakenly taken in the first place. Damages may even be [82]*82awarded to him for the wrongful deprivation. But no later' hearing and no damage award can undo the fact that the arbitrary taking , that was subject to the right of procedural due process has already occurred. “This Court has not . . , embraced the general proposition that a wrong may be done if it can be undone.” Stanley v. Illinois, 405 U. S. 645, 647.
This is no new principle of constitutional law. The right to a prior hearing has long been recognized by this Court under the Fourteenth and Fifth Amendments. Although the Court has held that due process tolerates variances in the form of a hearing “appropriate to the nature of the case,” Mullane v. Central Hanover Tr. Co., 339 U. S. 306, 313, and “depending upon the importance of the interests involved and the mature of the subsequent proceedings [if any],” Boddie v. Connecticut, 401 U. S. 371, 378, the Court has traditionally insisted that, whatever its form, opportunity for that hearing must be provided before the deprivation at issue takes effect. E. g., Bell v. Burson, 402 U. S. 535, 542; Wisconsin v. Constantineau, 400 U. S. 433, 437; Goldberg v. Kelly, 397. U. S. 254; Armstrong v. Manzo, 380 U. S., at 551; Mullane v. Central Hanover Tr. Co., supra, at 313; Opp Cotton Mills v. Administrator, 312 U. S. 126, 152-153; United States v. Illinois Central R. Co., 291 U. S. 457, 463; Londoner v. City & County of Denver, 210 U. S. 373, 385-386. See In re Buffalo, 390 U. S. 544, 550-551. .“That the hearing required by due process is subject to waiver, and is not fixed in form does not affect its root requirement that an individual be given an opportunity for a hearing before he is deprived of any significant property interest, except for extraordinary situations where some valid governmental interest is at stake that justifies postponing the hearing until after the event.” Boddie v. Connecticut, supra, at 378-379 (emphasis, in original).
[83]*83The Florida and Pennsylvania prejudgment replevin statutes fly in the face of this principle. To be sure, the requirements that a party seeking a writ must first post a bond, allege conclusorily that he is entitled to specific goods, and open himself to possible liability in damages if he is wrong, serve to deter wholly unfounded applications for a writ. But those requirements are hardly a substitute for a prior hearing, for they test no more than the strength of the applicant’s own belief in his rights.13 Since, his private gain is at stake, the danger is all too great that his confidence in his cause will be misplaced. Lawyers and judges are familiar with the phenomenon of a party mistakenly but firmly convinced that his view of the facts and law will prevail, and therefore quite willing to risk the costs of litigation. Because of the understandable, self-interested fallibility of litigants, a court does not decide a dispute until it has had an opportunity to hear both sides — and does not generally take even tentative action until it has itself examined the support for the plaintiff’s position. The Florida and Pennsylvania statutes do not even require the official issuing a writ of replevin to do • that much.
The minimal deterrent effect of a bond requirement is, in a practical sense, no substitute for an informed evaluation by a neutral official. More specifically, as a matter of constitutional principle, it is no replacement for the right to a prior hearing that is the only truly effective safeguard against arbitrary deprivation of property. While the existence of these other, less [84]*84effective, safeguards may. be among the considerations that affect the form of hearing demanded by due process, they are far. from enough by themselves to obviate the right to a prior hearing of some kind.
.V
The right to a prior hearing, of course, attaches only to the deprivation of an interest encompassed within the Fourteenth Amendment’s protection. In the present cases, the Florida and Pennsylvania statutes were applied to replevy chattels in the appellants’ possession. The replevin was not cast as a final judgment; most, if not all, .of the appellants lacked full title to the chattels; and their claim even to continued possession was a matter-in dispute... Moreover, the chattels at stake were nothing more than an assortment of household goods. Nonetheless, it is clear that the appellants were deprived of possessory interests in those chattels that were within the protection of the Fourteenth Amendment.
A
A deprivation of a person’s possessions under a prejudgment writ of replevin, at least in theory, may be only temporary. The Florida and Pennsylvania statutes do not require a person to wait until a post-seizure hearing and final judgment to recover what has beén replevied. Within three days after the seizure, the statutes allow him to recover the goods if he, in. return, surrenders other . property — a payment necessary to secure a bond in double the value of the goods seized from him.14 But it is now [85]*85well settled that a temporary, nonfinal deprivation of property is nonetheless a “deprivation” in the terms of the Fourteenth Amendment. Sniadach v. Family Finance Corp., 395 U. S. 337; Bell v. Burson, 402 U. S. 535. Both Sniadach and Bell involved takings of property pending a final judgment in an underlying dispute. In both cases, the challenged statutes included recovery provisions, allowing the defendants to post security to quickly regain the property taken from them.15 Yet the Court firmly held that these were deprivations of property that had to be preceded by a fair hearing.
The present cases are no different. When officials of Florida of Pennsylvania seize one piece of property from a person’s possession and then agree to return it if he surrenders another, they deprive him of property whether or not he has the funds, the knowledge, and the time needed to take advantage of the recovery provision. [86]*86The Fourteenth Amendment draws no bright lines around three-day, 10-day or 50-day deprivations of property. Any significant taking of property by the State is. within the purview of the Due Process Clause. While the length and consequent severity of a deprivation may be another factor to weigh in determining the appropriate form of hearing, it is not. decisive of the basic right to a prior hearing of some kind.
B
The appellants who signed conditional sales contracts lacked full legal title to the replevied goods. The Fourteenth Amendment’s protection of “property,” however, has never been interpreted to safeguard only the rights of undisputed ownership. Rather, it has been read broadly to extend protection to “any significant property interest,” Boddie v. Connecticut, 401 U. S., at 379, including statutory entitlements. See Bell v. Burson, 402 U. S., at 539; Goldberg v. Kelly, 397 U. S., at 262.
The appellants were deprived of such an interest in the replevied goods — the interest in continued possession and use of the goods. See Sniadach v. Family Finance Cory., 395 U. S., at 342 (Harlan, J., concurring). They had acquired this interest under the conditional sales contracts that entitled them to possession and use of the chattels before transfer of title. In exchange for immediate possession, the appellants had agreed to pay a major financing charge beyond the basic price of the merchandise. Moreover, by the time the goods were summarily repossessed, they had made substantial installment payments. Clearly, their possessory interest in the goods, dearly bought and protected by contract,16. [87]*87was sufficient to invoke the protection of the Due Process Clause.
Their ultimate right to continued possession was, of course, in dispute. If it were shown at a hearing that the appellants had defaulted on their contractual obligations, it might well be that the sellers of the goods would be entitled to repossession. But even assuming that the appellants had fallen behind in their installment payments, and that they had no other valid defenses,17 that is immaterial here. The right to be heard does not depend upon an advance showing .that one will surely prevail at the hearing. “To one who protests against the taking of his property without due process of law, it is no answer to say that in his particular case due process of law would have led to the same result because he had no • adequate defense upon the merits.” Coe v. Armour Fertilizer Works, 237 U. S. 413, 424. It is enough to invoke the procedural safeguards of the Fourteenth Amendment that a significant property interest is at stake,, whatever the ultimate outcome of a hearing on the contractual right to continued possession and use of the goods.18
[88]*88c
Nevertheless, the District Courts rejected the appellants’ constitutional claim on the ground that the goods seized from them — a stove, a stereo, a table, a bed, and so forth — were not deserving of due process protection, since they were not absolute necessities of life. The courts based this holding on a very narrow reading of Sniadach v. Family Finance Corp., supra, and Goldberg v. Kelly, supra, in which this Court held that the Constitution requires a hearing before prejudgment wage garnishment and before the termination of certain welfare benefits. They reasoned .that Sniadach and Goldberg, as a matter of constitutional principle, established no more than that a prior hearing is required with respect to the deprivation of such basically “necessary” items as wages and welfare benefits.
This reading of Sniadach ahd Goldberg reflects the premise that those cases marked a radical departure from established principles of procedural due process.. They did not. Both decisions were in the mainstream of past cases, having little or nothing to do with the absolute “necessities” of life but establishing that due process requires an opportunity for a hearing before a deprivation of property takes effect.19 E. g., Opp Cotton Mills v. Administrator, 312 U. S., at 152-153;, United States v. Illinois Central R. Co., 291 U. S., at 463; Southern R. Co. v. Virginia, 290 U. S. 190; Londoner v. City & County of Denver, 210 U. S. 373; Central of Georgia v. Wright, 207 U. S. 127; Security Trust [89]*89Co, v. Lexington, 203 U. S. 323; Hibben v. Smith, 191 U. S. 310; Glidden v. Harrington, 189 U. S. 255. In none of those cases did the Court hold that this most basic due process requirement is limited to the protection of only a few types of property interests. While Sniadach and Goldberg emphasized the special importance of wages and welfare benefits, they did not convert that emphasis into a new and more limited' constitutional doctrine.20
Nor did they carve out a rule of “necessity” for the sort of nonfinal deprivations of property that they involved. That was made clear in Bell v. Burson, 402 U. S. 535, holding that there must be an opportunity for a fair hearing .before mere suspension of a driver’s license. A driver’s license clearly does not rise to the level of “necessity” exemplified by wages and welfare benefits. Rather, as the Court accurately stated, it is an “important interest,” id., at 539, entitled to the protection of procedural due process of law.
The household goods, for which the appellants, contracted and paid substantial sums, are deserving of similar protection. While a driver’s license, for example, “may become [indirectly], essential in the' pursuit of a livelihood,” ibid., a stove or a' bed may be equally éssen-tiál to provide a minimally decent environment for human, Beings in their day-to-day lives. „ It is,' after all, such consumer goods that people work and earn a livelihood in order to acquire.
No doubt, there may be many gradations in the “importance” or “necessity” of various consumer goods. Stoves could be compared, to television sets, or beds [90]*90could be compared to tables. But if the root principle of procedural due process is to be applied with objectivity, it cannot rest on such distinctions. The Fourteenth Amendment speaks of “property” generally. And, under our free-enterprise-system, an' individual’s choices in the marketplace are respected, however unwise they may seem to someone,’ else. It is not the business of a court adjudicating due process rights to make its own critical evaluation of those choices and protect only the ones that, by its own lights, are “necessary.” 21 -
VI
There are “extraordinary situations” that justify postponing notice and opportunity for a hearing. Boddie v. Connecticut, 401 U. S., at 379. These situations, however, must be truly unusual.22 Only in a few limited sit[91]*91uations has this Court allowed outright seizure23 without opportunity for a prior hearing. First, in each case, the seizure has been directly necessary to secure an important governmental or general public interest. Second, there has beén a special need for very prompt action. Third, the State has kept strict control over its monopoly of legitimate force: the person initiating the. seizure has been a government official responsible for determining, under the standards of ¿ narrowly drawn statute, that it. was -necessary and justified in the particular instance. Thus, the Court has allowed summary seizure of property [92]*92to collect the internal revenue of the United States,24 to meet the needs of' a national war effort,25 to protect against the economic disaster of a bank failure,26 and to ^protect the public from misbranded drugs27 and contaminated food.28
The Florida and Pennsylvania prejudgment replevin statutes serve no such important governmental or general public interest. They allow, summary seizure of a person’s possessions when no more than private gain is directly at stake.29 The réplevin of chattels, as in the [93]*93present cases, may satisfy a debt or settle a score. . But state intervention in a private dispute hardly compares to state action furthering a war effort or protecting the., public health.
Nor do the broadly drawn Florida and Pennsylvania statutes limit the summary seizure of goods to special situations demanding prompt action. There may be. cases in which a creditor could make a showing of immediate danger that, a debtor will destroy or conceal disputed goods. But the statutes before us are not-'‘narrowly drawn to meet any such unusual condition.” Sniadach v. Family Finance Corp., supra, at 339. And no such unusual situation is presented by the facts of these cases.
The statutes, moreover, abdicate, effective state control over state power. Private parties, serving their own private advantage, may unilaterally invoke state power to replevy goods from another.. No state official participates in the decision to seek a writ; no state official reviews the basis for the claim to repossession; and no state official evaluates) the need for immediate seizure. There is not even a requirement that the plaintiff provide any information to the court on these matters. The State acts largely in the dark.30
[94]*94VII
Finally, we must consider the contention that the appellants who signed conditional sales contracts thereby waived their basic procedural due process rights. The contract signed by Mrs. Fuentes provided that “in the event of default of any payment or payments, Seller at its option may take back the merchandise . . . .” The contracts signed by the Pennsylvania appellants similarly provided that the seller “may retake” or “repossess” the merchandise in the event of a “default in any payment.” These terms .were parts of printed form contracts, appearing in relatively small type and unaccompanied by any explanations clarifying their meaning.
In D. H. Overmyer Co. v. Frick Co., 405 U. S. 174, the Court recently outlined the considerations relevant to determination of a contractual waiver of due process rights. Applying, the star dards governing waiver of constitutional rights in a criminal proceeding31 — although not holding that such standards must necessarily apply — the Court held that, on the particular facts of that case, the contractual waiver of due process [95]*95rights was “voluntarily, intelligently, and knowingly” made. Id., at 187. The contract in *Overmyer was negotiated between two corporations; the waiver provision was specifically bargained for and drafted by their lawyers in the process of these negotiations. As the Court noted, it was “not a case of unequal bargaining power or overreaching. The Overmyer-Frick agreement, from the start, was not a contract of adhesion.” Id., at 186. Both parties were “aware of the significance” of the waiver provision. Ibid.
The facts of the present cases are a' far cry .from those of Overmyer. There was no bargaining over contractual terms between the parties who, in any event, were far from equal in bargaining power. The purported waiver provision was a printed part of a form sales contract and a necessary condition of the sale. The appellees .made no showing whatever that the appellants were actually aware or made aware of the significance of the fine print now relied upon as a waiver of constitutional rights.
The Court in Overmyer observed that “where the contract is one of adhesion, where there is great disparity in bargaining power, and where the debtor receives nothing for the [waiver] provision, other legal consequences may ensue.” Id., at 188. Yet, as in Over-myer, there is no need in the present cases to canvass those consequences fully. For a waiver of constitutional rights in any context must, at the very least, be clear. We need not concern ourselves with the in voluntariness or unintelligence of a waiver when the contractual language relied upon does not, on its face, even amount to a waiver.
The conditional sales contracts here simply provided that upon a default the seller “may take back,” “may retake” or “may repossess” merchandise. The contracts [96]*96included nothing about the waiver of a prior hearing. They did not indicate how .or through what process— a final judgment, self-help, prejudgment replevin with a prior hearing, or prejudgment replevin without a prior hearing-^-the seller could take back the goods. Rather, the purported waiver provisions' here are no more than a statement of the seller’s right to repossession upon occurrence of certain events. The appellees do not suggest that these provisions waived the appellants’ right to a full post-seizure hearing to determine whether those events had, in fact, occurred and to consider any other available defenses. By-the same token, the language of the purported waiver provisions did not waive the appellants’ constitutional right to a preseizure hearing of some kind.
VIII
We hold that the Florida and Pennsylvania prejudgment replevin provisions work a deprivation of property without due process of law insofar as they deny the right to a prior opportunity to be heard before chattels are taken from their possessor.32 Our holding, however, is a narrow one. We do not question' the power of a State to seize goods before a final judgment in order to protect the security interests of creditors so long as those' creditors have tested their claim to the goods through the process of a fair prior hearing. The nature and form of such prior hearings, moreover, are legitimately open to many potential variations and are a [97]*97subject, at this point, for legislation — not adjudication.33 Since the essential reason for the requirement of a prior hearing is to prevent unfair and mistaken deprivations of property, however, it is axiomatic that the hearing must provide a real test. “[D]ue process is afforded only by the kinds of ‘notice’ and ‘hearing’ that are aimed at establishing the validity, or at least the probable validity, of the underlying claim against the alleged debtor before he can be deprived of his property . . . .” Sniadach v. Family Finance Corp., supra, at 343 (Harlan, J., concurring) . See Bell v. Burson, supra, at 540; Goldberg v. Kelly, supra, at 267.
For the foregoing reasons, the judgments of the District Courts are vacated and these cases are remanded for further proceedings consistent with this opinion.
It is so ordered.
Mr. Justice Powell and Me. Justice Rehnquist did not participate in the consideration or decision of these ' cases.
