Co-Authorship Rules for Research Papers: Who Qualifies and Order

A person qualifies as a co-author only if they made a real intellectual contribution to the paper, helped write or critically revise it, approved the final version and accept responsibility for it. Author order, the corresponding author and each person’s role should be agreed in writing before you start writing, not after the paper is accepted. This guide sets out the common rules and gives you templates to avoid disputes.

Who qualifies as an author

There is no single law that defines authorship of a research paper in India, so journals rely on recognised ethics guidance. The most widely cited criteria come from the International Committee of Medical Journal Editors (ICMJE). Although written for medical journals, they are used as a benchmark in many disciplines. In summary, an author should:

1. Make a substantial contribution to the conception or design of the work, or to gathering, analysing or interpreting the material.
2. Draft the paper or revise it critically for important content.
3. Approve the final version to be published.
4. Agree to be accountable for all aspects of the work.

Law and social science journals often apply a simpler version of the same idea: every author must have contributed to the ideas and the writing, and every author must be able to defend the paper.

Who does not qualify on that basis alone

• A supervisor or head of department who only gave general permission or reviewed the topic.
• Someone who only arranged funding, access or data.
• A friend who only proofread or formatted the paper.
• A senior added to “add weight” to the submission.

These people can be thanked in the acknowledgements. Adding them as authors is called gift or honorary authorship. Leaving out someone who did qualify is ghost authorship. Both are treated as misconduct by journals that follow ethics guidance.

Order of authors

Conventions differ across fields, which is why you must agree on order early.

In student papers in Indian law journals, contribution order is the most common. If you use alphabetical order, consider adding a note so readers do not assume a ranking.

The corresponding author

The corresponding author handles communication with the journal on behalf of all authors. Their duties usually include:

• Submitting the manuscript and declarations.
• Confirming that all co-authors have approved the submission.
• Receiving and sharing reviewer comments, and coordinating revisions.
• Signing or arranging signature of the copyright or licence agreement.
• Answering post-publication queries and corrections.

The corresponding author does not have to be the first author. Choose the person who is most reliable on email and deadlines. Use an email address that will still work in two years; a college email that expires after graduation causes real problems later.

Contribution statements

Many journals now ask for a statement describing what each author did. A recognised framework is CRediT (Contributor Roles Taxonomy), which lists standard roles such as conceptualisation, methodology, investigation, formal analysis, writing (original draft), writing (review and editing), supervision and project administration.

Template

Author contributions: A. Sharma: conceptualisation, research, writing (original draft). P. Rao: methodology, analysis of case law, writing (review and editing). Both authors approved the final manuscript.

A clear statement protects everyone. It records who did what if a question is raised later.

Agree on authorship in writing before you start

Most authorship disputes come from assumptions made at the start of a project. A short written note, even an email that everyone replies “agreed” to, prevents most of them. Cover these points:

1. Working title and target journal.
2. Who will be an author and in what order.
3. Who will be the corresponding author.
4. Division of work and internal deadlines.
5. What happens if someone drops out or does much less than agreed (for example, they move to the acknowledgements).
6. How fees, if any, will be shared.
7. Who may reuse the material later, for example in a dissertation.

Changing authors after submission

Journals are cautious about authorship changes after submission because they can signal disputes or gift authorship. If you need to add, remove or reorder authors:

• Inform the editor before acceptance where possible.
• Give a reason.
• Provide written consent from every author, including anyone being removed.

Many journals will not process changes after acceptance or publication except through a formal correction.

Handling an authorship dispute

1. Talk first. Most disputes come from misunderstanding. Refer back to your written agreement.
2. Use the evidence. Drafts, email threads and version histories show who contributed what.
3. Involve a neutral senior such as a supervisor or the institution’s research integrity body.
4. Inform the journal if the paper is under review. Editors will usually pause the process until authors agree; journals are not generally in a position to decide who is right.
5. Do not submit without consent. Submitting a jointly written paper alone, or without a co-author’s approval, is a serious ethics breach.

Co-authorship and your career

Co-authored papers count, but selection committees often look at your role. A list of papers where you are always the fourth of five authors says less than two papers where you are the first or sole author. Plan a mix: some solo work that shows your independent thinking, and collaborations that build your network.

Also make sure your institution’s affiliation rules are followed and every author’s affiliation is accurate. If the paper used AI tools, all authors share the duty of disclosure: see rules on AI use in research papers. Ownership questions between co-authors are covered in copyright in research papers.

Frequently asked questions

Can my supervisor insist on being a co-author?

A supervisor qualifies as a co-author only if they made a substantial intellectual contribution and helped write or critically revise the paper. General guidance or permission is better recognised in the acknowledgements. Discuss it openly and refer to the journal’s authorship policy.

How many co-authors can a law paper have?

Many law journals set a limit, often two or three authors for student submissions. Check the author guidelines before you finalise the team.

Does the first author get more credit?

In contribution-order fields, yes, the first author is presumed to have done the most work. Where order is alphabetical, a note clarifying equal contribution helps.

Who should be the corresponding author?

Whichever author can reliably manage communication with the journal, including revisions and agreements. It need not be the first author.

What is a certificate of publication for co-authors?

Many journals issue each named author a certificate. Read certificate of publication explained to see what makes one verifiable.
