Co-Parenting Agreement: What Should Be Included?
A co-parenting agreement can help clarify expectations before having a child together. Here are the key topics to discuss and include.
When two people decide to have and raise a child together, they may agree on the big picture very quickly.
They both want to be involved. They both want what is best for the child. They trust each other.
The harder questions usually live in the details.
Where will the child live? How will expenses be divided? What happens if one parent wants to move? Who makes medical decisions? What happens when either parent enters a serious relationship?
A co-parenting agreement is one way to put those conversations in writing before they become real-life disagreements.
It does not need to predict every situation your family will ever face. Its purpose is to make expectations clearer and give both people a shared starting point.
What is a co-parenting agreement?
A co-parenting agreement is a document that records how two people intend to approach raising a child together.
It may cover practical responsibilities, financial arrangements, decision-making and the kind of relationship both parents expect to have with the child.
This can be especially useful for intentional co-parents who are choosing to have a child together without being in a romantic relationship.
But there is an important distinction between an agreement and the law.
Depending on where you live, a private co-parenting agreement may not determine legal parenthood, custody, financial responsibilities or what a court would decide if a dispute arose.
That is why the agreement should be treated as part of the planning process—not as a substitute for professional legal advice.
Start with each person's intentions
Before getting into schedules and expenses, record what both people are actually agreeing to.
Are you both intending to be full parents?
Will the child know both of you as parents from birth?
Do you expect roughly equal involvement, or will one person take on a larger day-to-day role?
These points may feel obvious while everything is going well, but writing them down helps ensure that both people are entering the arrangement with the same understanding.
This is particularly important when donor conception is involved, because the difference between being a donor and being a co-parent should be absolutely clear.
Where will the child live?
Living arrangements are one of the most practical areas to address.
You might discuss:
- Where the child is expected to live after birth
- Whether both parents will maintain separate homes
- How close those homes should ideally be
- How parenting time may be divided
- How arrangements might change as the child grows
A schedule for a newborn may look completely different from one for a school-age child, so avoid creating an agreement that assumes one timetable will work forever.
Instead, record the general principles you want to follow and how you intend to review the arrangement over time.
How will parenting time be divided?
If both people intend to have an active parenting role, discuss what that means in practice.
Will one parent take weekdays and another weekends? Will time be divided more evenly? How will holidays and birthdays work?
You may also want to think about:
- School holidays
- Travel
- Important family occasions
- Religious celebrations
- Mother's Day or Father's Day
- Time with grandparents and extended family
You do not need to schedule the next 18 years.
The more useful goal is to agree on how both parents will remain meaningfully involved and how scheduling decisions will be made.
How will financial responsibilities work?
Money deserves its own section.
Consider expenses such as:
- Pregnancy and fertility-related costs
- Childcare
- Healthcare
- Clothing
- Food
- Housing
- Education
- Extracurricular activities
- Travel
- Insurance
Will costs be split equally?
Will contributions be based on income?
What happens if one parent earns significantly more than the other?
Also discuss how larger or unexpected expenses will be approved.
A simple principle such as “major expenses should be discussed beforehand” can be just as useful as setting exact amounts.
Who makes important decisions?
Parenting involves hundreds of everyday choices, but some decisions have much larger consequences.
Your agreement might address how you intend to make decisions about:
- Healthcare
- Schooling
- Religion
- Where the child lives
- International travel
- Major extracurricular commitments
- Changes of surname
- Important medical procedures
What happens if you disagree?
It may be useful to agree that major decisions require discussion between both parents, while routine decisions can be made by whichever parent is caring for the child at the time.
What happens if someone wants to move?
Relocation can completely change a co-parenting arrangement.
A move across town may be manageable. A move to another city or country may make regular parenting time much harder.
Discuss whether either person expects to relocate in the future and what should happen before a significant move.
For example, you might agree that relocation plans should be discussed well in advance rather than announced after a decision has already been made.
Even if the agreement cannot determine the legal outcome of a future relocation dispute, having the conversation now can reveal whether your long-term plans are compatible.
What about future partners?
If the co-parents are not romantically involved, future relationships are likely to become part of family life eventually.
You may want to discuss:
- When serious partners should meet the child
- Whether the other co-parent should meet them first
- What role a future spouse or partner may have
- Whether future partners can participate in parenting decisions
- What happens if a future relationship involves relocation
It is usually unrealistic to create rigid rules about people who do not yet exist in your lives.
Still, discussing boundaries and expectations now can prevent assumptions later.
How will you handle disagreements?
Even highly compatible co-parents will disagree eventually.
A useful agreement can include a process for handling disputes.
That might mean:
- Discussing the issue directly
- Allowing time before making a major decision
- Using mediation if you cannot reach agreement
- Obtaining professional advice where necessary
The goal is not to eliminate conflict.
It is to decide how you want to respond to conflict before emotions are high.
Include a review process
Families change.
A plan that works when a child is two may not make sense when they are twelve.
Consider agreeing to review your co-parenting arrangement periodically or after major life changes.
That might happen when:
- The child starts school
- One parent moves
- Someone's work situation changes
- A parent enters a serious relationship
- Another child joins either household
A good agreement should be able to evolve.
Get legal advice before relying on the agreement
This is especially important.
Legal parenthood, parental responsibility, child maintenance and parenting arrangements are governed by the law where you live.
A private agreement does not necessarily override those rules.
For example, UK fertility guidance notes that co-parenting or donor agreements can be useful for recording intentions, but they do not automatically determine someone's legal or financial responsibilities.
If donor conception, fertility treatment or a private donation arrangement is involved, the route to conception can also affect legal parenthood.
Before trying to conceive, both prospective parents should therefore consider obtaining independent legal advice in their own jurisdiction.
The conversation may matter as much as the document
A co-parenting agreement is valuable partly because of what ends up on paper.
But its greatest value may come from the conversations required to create it.
Talking about money, relocation, discipline, future partners and disagreements can expose differences before those differences affect a child.
Banbino can help people connect with others who are looking for the same family-building arrangement, including intentional co-parenting. But finding someone who shares the label “co-parent” is only the beginning.
Before making the decision to have a child together, make sure you both understand what that role means.
A thoughtful agreement cannot guarantee that life will follow the plan.
It can, however, make sure that you begin with far fewer assumptions.
