Authorship disputes are among the most common conflicts in research. Disagreements over who should be listed as an author, in what order, or how credit is shared can damage working relationships, delay publications, and even lead to formal complaints. The good news is that most authorship disputes can be prevented with clear communication and simple planning.
This guide on how to avoid authorship disputes offers practical strategies for researchers, supervisors, and students, from setting expectations at the start of a project to handling changes and resolving disagreements if they arise.

Why Authorship Disputes Happen
Authorship matters because it affects careers, funding, promotions, and professional reputation. Common causes of disputes include:
- No early discussion about who will be an author
- Different understandings of what counts as a contribution
- Disagreement over the order of authors
- Changes in roles as a project develops
- Team members joining or leaving partway through
- Power imbalances between senior and junior researchers
- Different norms across disciplines or countries
Start the Conversation Early
The single most effective way to avoid disputes is to discuss authorship at the beginning of a project, before any data is collected or analysed. Early conversations help everyone understand expectations and reduce surprises later.
Key questions to discuss include:
- Who is expected to contribute to each part of the project?
- Which criteria will be used to decide authorship?
- How will author order be determined?
- Who will be the corresponding author?
- How many papers are expected from the project?
- What happens if someone’s role changes or they leave?
Agree on Authorship Criteria
Teams should agree on clear criteria for authorship. Many fields follow guidance from the International Committee of Medical Journal Editors (ICMJE), which recommends that authors make substantial contributions, help draft or critically revise the work, approve the final version, and accept accountability. Other disciplines have their own norms, so it is important to check relevant journal and professional guidelines.
Agreeing on criteria helps the team decide who qualifies as an author and who should be acknowledged instead.
Create a Written Authorship Agreement
A simple written agreement can prevent misunderstandings. It does not need to be complicated or legally formal.
| Item to Include | Why It Helps |
|---|---|
| Expected contributors and their roles | Clarifies responsibilities from the start |
| Authorship criteria | Sets a shared standard |
| Proposed author order | Reduces later disagreements |
| Corresponding author | Identifies who manages submission and communication |
| Process for changes | Explains how roles and order can be updated |
| Dispute resolution steps | Provides a clear path if disagreements arise |
Share the agreement by email or in a shared document so everyone has a copy. Some universities provide authorship agreement templates through their research offices, which can save time and ensure key points are covered.
Understand Author Order Conventions
Author order means different things in different fields:
- Many life and medical sciences: the first author did most of the work, and the last author often leads the research group
- Some social sciences: order reflects the size of contribution
- Mathematics, economics, and some physics fields: authors are often listed alphabetically
- Large collaborations: may list authors alphabetically or by group
Discussing these conventions is especially important in interdisciplinary teams, where members may have different expectations.
Shared or Equal Contributions
When two or more people contribute equally, many journals allow a note indicating “equal contribution” or “joint first authorship.” Agreeing on this early can prevent competition for the first position.
Document Contributions as You Go
Memories fade over long projects. Keeping records helps everyone remember who did what:
- Keep a project log of tasks and contributors
- Record decisions from team meetings
- Track who wrote and revised each section of a manuscript
- Use contributor role frameworks, such as the CRediT taxonomy, to describe contributions clearly
Revisit Authorship Regularly
Projects evolve. Someone may take on more work than expected, while another person may contribute less. Revisit authorship agreements at key milestones, such as:
- After data collection
- Before drafting the manuscript
- Before submission
- When new team members join or others leave
Open, regular check-ins make adjustments feel fair rather than sudden, and they give everyone a chance to raise concerns while they are still easy to resolve.
Special Considerations for Students and Supervisors
Authorship between students and supervisors can be sensitive because of the power imbalance.
- Supervisors should explain authorship expectations clearly from the start
- Students who do most of the work on thesis-based papers are commonly first authors
- Supervisors should avoid demanding authorship without meaningful contribution
- Students should feel safe raising questions without fear of consequences
Working in International and Interdisciplinary Teams
Teams spanning different countries, institutions, or fields may have different authorship traditions. Fair practices include recognising local collaborators, especially in research conducted in lower-income countries, and agreeing early on how contributions from each partner will be credited.
Common Scenarios and How to Handle Them
A Team Member Leaves the Project
Agree in advance how departing members will be credited for work already completed. If they meet authorship criteria, they should be kept informed and given the chance to approve the final manuscript.
Someone Contributes More Than Expected
If a team member takes on a much larger role, such as rescuing a stalled analysis, revisit the author order openly rather than assuming the original plan still applies.
A Senior Colleague Asks to Be Added
Politely refer to the agreed criteria and discuss what contribution they could make. If they have not contributed substantially, offering an acknowledgement may be more appropriate.
Multiple Papers from One Project
Plan authorship for each expected paper, so team members can lead different publications and share first-author opportunities fairly.
Before Submission: Final Checks
- Confirm that all authors meet agreed criteria
- Ensure every author has reviewed and approved the final manuscript
- Check that author names, affiliations, and order are correct
- Include contributor statements if the journal requires them
- Acknowledge non-author contributors with their permission
Handling Changes After Submission
Changing authorship after submission is possible but usually requires approval from all authors and the journal. Editors often ask for a written explanation and signed agreement. Making changes after publication is more complex and may require a formal correction.
What to Do If a Dispute Arises
- Talk directly: discuss concerns calmly and privately with co-authors
- Refer to agreements: use your written agreement and contribution records
- Seek mediation: involve a neutral colleague, mentor, or ombudsperson
- Contact institutional offices: research integrity offices can provide guidance
- Involve the journal if necessary: editors generally expect authors and institutions to resolve disputes but may pause publication until they are settled
Many journals follow guidance from the Committee on Publication Ethics when handling authorship disputes.
Final Thoughts
Learning how to avoid authorship disputes comes down to communication, clarity, and fairness. By discussing authorship early, agreeing on criteria, putting expectations in writing, documenting contributions, and revisiting plans as projects evolve, research teams can prevent most conflicts before they begin. Clear authorship practices protect relationships, careers, and the integrity of research.
