How can I prove that I designed the site? I have designed a website for a client, But there is no contract between us. The client does not pay my salary, But our text and voice messages are available. How can I prove that I designed the site and complain about him?
By &quot;complain&quot; I assume you mean &quot;take legal action against him&quot;. You would need a legal basis, and a lawyer. When you say that you don't have a contract, I assume you mean that you don't have a piece of signed paper, but you do have an agreement – which is a contract. As far as websites are concerned, there are only a few likely causes of legal action: copyright infringement, and non-payment for services. As far as copyright is concerned, this law may be relevant. If we assume that you and the client are operating in Iran, your copyright is protected, but Iran does not enforce other country's copyright laws (they are not signatories to the Berne Convention). If the issue is that the client is not paying for services rendered, you can sue them. The civil code (in English) is here. See article 219 ff. for the specifics, but basically you show the judge that there is an agreement, and that you were not paid. The client can then argue that you didn't actually do the job agreed to, or that you were paid. There are other possible responses (e.g. the &quot;client&quot; might prove that you agreed to do the work for free), the details of which will come out in your discussion with the lawyer.
You clearly cannot provide data that you haven't stored – and not storing data is a good thing under the Art 5(1)(c) Data Minimization Principle. Despite the Art 20 data portability right being conditional on that the data subject has provided data and not on that data has been stored, I think responding to such a request with “sorry, as per our privacy policy we do not store this data” would be perfectly fine. It is also curious that you are using consent as the legal basis for the purpose of selecting the website language. How do you obtain consent from visitors? How can you prove that you got consent? In many ways, consent is the legal basis of last resort, and I'd think that legitimate interest would be a much more straightforward approach in your case.
You can hire someone to locate the defendant with the information that you have, or you can apply to a court for permission to serve them with process via &quot;substituted service&quot; because their physical address can't be determined. But, in general, better business practice is to not enter into contracts with people with whom you have more than a name that might be false, and an email address, unless you have some means of non-judicial enforcement of your agreement (like the practical ability to shut down access to an internet subscription). If you don't even know if someone's name is real and have done nothing to confirm that then you also have no assurances that they have any assets from which you could collect if you won a breach of contract lawsuit. If you deal with large numbers of people in low value contracts, it may be worth treating the fact that some contracts are effectively unenforceable as a cost of doing business. But, if a contract is important, it was foolish from a business perspective to rely on a contract on that basis alone, even if it is legal to do so.
if a manager emailed an prospective employee a contract containing the pay rate of $20/hr, if the prospective employee crossed out $20/hr and replaced it with $25/hr, then went to work and gave the manager the contract which he failed to carefully read, continued working for a few months, would the employee be entitled to $20/hr? A party ought to timely alert or notify the other counterparty about any disagreements or proposed changes. This is especially recommendable when evidence suggests that the counterparty's expectation that the party only would sign the contract was reasonable. In the example you outline, the employee's unilateral alteration of the compensation/rate in the contract seems unlikely to favor the employee's position. That is because typically employer and employee negotiate compensation prior to formalizing their agreement. In that case, the employee would need stronger evidence with which to overcome the employer's credible argument that he did not knowingly accept the altered rate.
The question does not say what reasons the other party gives for not paying, and so one cannot judge whether such reason is covered by the terms quoted in the question. In general a contract need not be highly specific if the intent is clear. However, any ambiguity will usually be resolved against the party who wrote the contract, so it is in that party's interest to be as clear and specific as possible. It is not clear from the quoted terms that they form a contract at all. No consideration is stated. Contractual provisions which deny all recourse are not always enforceable. They may be overruled by law or regulation, or by prior court decision or by an equitable decision. If there is a serious problem with the service provided, particularly in a consumer transaction, a court might reject a provision denying all refunds even if it is quite specific and clear. The question does not list the jurisdiction (country and, for federal countries, state or province). Laws on contracts and enforceable terms vary significantly in different jurisdictions. Without this a specific answer is not possible.
You already have a contract(s): you do work and they pay you is pretty much all you need to have a contract. Given that there is already a contract, formalising it in writing does not expose you to any greater risk and usually, clearly defining the terms of a contract reduces risk all around.
The issue of who pays directly for the items and/or to contractors is irrelevant. The important thing is to memorialize the agreement/arrangement in writing so as to preempt or solve eventual disputes. A clearly written agreement signed by the parties would supersede any presumption of conditions and rights arising solely from the parties' conduct.
It's not clear whether you mean that the entire agreement is carried out by text message. If you have a paper or electronic document stating what the parties will do, that is the agreement, and signatures are a conventional form of proof that there is an agreement. A handshake or a verbal statement – or text mesage – could also serve as evidence of the agreement, though there could be problems with the quality of the evidence (e.g. how do the witnesses know which piece of paper you agreed to). There is not a huge body of law surrounding text messages (and apparently none regarding text messages and contracts). We know that a text message is not a "printed receipt" (Shlahtichman v. 800 Contacts), and that a text message is a "call" w.r.t. the Do-Not-Call law (Campbell-Ewald Company v. Jose Gomez, Keating v. Nelnet). The closest that I have been able to come in terms of a decision about whether a text message is "written" is Commonwealth v. Mulgrave 472 Mass. 170, which states that While Massachusetts appellate courts have yet to approve admission of text messages or any other writing under the spontaneous utterance exception to the hearsay rule... The wording "any other writing" implies that the court believes text messages to be "writing", which of course it is if you look at the plain meaning of the word "write". Contracts can be formed and signed by email: 15 USC 7001 states that a signature, contract, or other record relating to such transaction may not be denied legal effect, validity, or enforceability solely because it is in electronic form....a contract relating to such transaction may not be denied legal effect, validity, or enforceability solely because an electronic signature or electronic record was used in its formation so the fact of electronic writing does not make the contract non-written. There must be a venerable and well-known rationale behind the written / oral asymmetry, which presumably has to do with the volatility of memory which would be front and center in a dispute about oral contracts. FRE 1001 "clarifies" that a "writing" consists of letters, words, numbers, or their equivalent set down in any form, and that a "recording" consists of letters, words, numbers, or their equivalent recorded in any manner. 15 USC 7001 also states that An oral communication or a recording of an oral communication shall not qualify as an electronic record for purposes of this subsection except as otherwise provided under applicable law So a recording of an oral contract would be useful to prove that there was an agreement, but would not change the fact that the contract is oral.
