A seemingly simple question, but if not included in the contract, you may lose control over the entire sales kit later.
With the sales kit and marketing materials, you can request the original files and editing rights. This is a healthy standard in design collaboration. It is important to specify two things in the contract: who owns the rights, and whether the source files will be delivered and when. According to Article 39 of the Intellectual Property Law, the ownership rights to works created under a contract default to the party commissioning the work when signing directly with the author, unless otherwise agreed; when signing with a studio, the rights typically transfer to you through a transfer clause, and many design contracts specify conditions, so it is necessary to read the terms carefully. Additionally, fonts, stock images, and illustrations purchased from third parties may come with separate restrictions beyond the studio's control.
The original files are something you should proactively ask for right when discussing the scope, not wait until delivery to remember. The studio holding the files does not always have bad intentions, but if it is not clearly stated in the contract, everything can become a point of contention later. Below are things for you to know what you can request and what you need to check before signing.
When referring to "original files" in the sales document package project, you should understand that it includes at least four things:
.ai Or .eps.If the studio only delivers PDFs or exported images, you receive the results but not the tools. These two are completely different.
According to Article 39 of the Intellectual Property Law, when a work is created under a contract for hire, the ownership rights default to the party commissioning the work, unless the contract states otherwise. When you sign with a studio as a legal entity, the studio is usually the original owner of the works created by their employees, and the rights transfer to you through a transfer clause in the contract. The moral rights of the author, such as attribution or integrity of the work, remain with the creator. Since this default can be reversed by contract, you need to read the transfer clause carefully, which often includes conditions for full payment, and compare it with the current laws and any recent amendments.
Ownership rights and the delivery of source files are two different matters: having rights does not mean the studio must deliver the files, so the contract needs to specify both. The "work made for hire" doctrine is a concept from U.S. copyright law, and you should not copy foreign clauses directly into domestic contracts. For specific cases, it is advisable to consult a lawyer.
Even if the studio is willing to deliver all files, there are still parts that cannot be freely transferred due to third-party dependencies:
You should ask the provider to clearly list any third-party assets in the deliverables, so you know which parts need separate handling.
Holding onto files to demand more money can damage your reputation. Delivering files with goodwill leaves a positive final impression and opens up opportunities for future collaboration.
Practical experience, according to Michael Janda, Should You Deliver Source Files to Clients
There are three ways to use the files after delivery, each suitable for different circumstances. If the business has someone familiar with design, they can edit it themselves, which is the cheapest and fastest option. If the business does not have such a person, they can hire a freelancer or another studio as needed, and in that case, a well-organized layered file determines whether their work goes smoothly. Returning to the original studio is appropriate for major changes, as it is important to maintain the original spirit of the documentation.
Regardless of the chosen method, there should be at least one person on the team who is familiar with opening files or understands enough to delegate tasks to outsiders. Receiving files without anyone understanding the structure means you still depend on the studio as before, even though you may have full ownership on paper.

You need to separate this into two questions. Regarding rights: according to Article 39 of the Intellectual Property Law, when signing directly with the author, the ownership rights default to the party commissioning the work unless the contract states otherwise; signing with a studio typically requires a transfer clause. The moral rights still belong to the individual author (the designer). Regarding the files: if the contract is silent, there is no obligation for the studio to deliver the source files, as what is purchased may only be the final result. The safe approach is to clearly state both points before signing or before the final payment. For specific clauses, it is advisable to consult a lawyer.
Legally, yes, but in practice, it may not be sufficient. Receiving Illustrator or Figma files without anyone on the team skilled enough to open and edit them means you still depend on the studio as before. When receiving the files, you should check that they are openable, layers are clearly separated, and at least one person understands the file structure well enough to hire someone else for editing later.
