Paternity & Legal Parentage in Michigan
If the parents were married at the time of the child’s birth, Michigan law generally presumes that both spouses are the child’s legal parents. For unmarried parents, legal parentage must be formally established before a father has enforceable custody or parenting-time rights. Until paternity is established, the mother typically has sole legal custody of the child, subject to later court orders.
​
Establishing paternity creates the legal parent-child relationship, but it does not automatically determine custody or parenting time. Once paternity is established, either parent may seek custody and parenting time through the court, and decisions will be made based on the child’s best interests.
​
Paternity is established in Michigan with:
​
-
Affidavit of Parentage
-
A voluntary form signed by both parents, often completed at the hospital or later through the state.
-
-
Court-Ordered Genetic Testing
-
Used when parentage is disputed or uncertain.
-
-
Judicial Determination of Paternity
-
A court order formally establishing legal parentage.
-
​
Once legal parentage is established, Michigan courts may issue orders addressing custody, parenting time, and decision-making authority.
Best Interest of the Child Standard
All custody and parenting-time decisions are guided by the best interest of the child. Courts apply this standard when determining legal custody, physical custody, and parenting time, with the goal of promoting the child’s stability, safety, and healthy development. These best-interest determinations are reflected in the court’s child custody order, which sets out legal custody, physical custody, and parenting time.
​
Michigan law sets out specific best-interest factors that courts must consider. Rather than focusing on a single issue or parent, judges evaluate the child’s overall circumstances and how each parent’s involvement affects the child’s well-being, both now and over time.
​
A few best interest of the child factors:
​
-
The emotional ties between the child and each parent
-
Each parent’s ability to provide love, guidance, and a stable environment
-
The child’s adjustment to home, school, and community
-
Each parent’s willingness to support the child’s relationship with the other parent
-
The mental and physical health of all individuals involved
-
Any history of domestic violence or substance abuse
​
Depending on the child’s age and maturity, courts may also consider the child’s reasonable preference, along with any other factor relevant to the child’s best interests.
​
Michigan courts do not begin with a presumption in favor of either parent. Instead, the focus remains on creating custody and parenting-time arrangements that support consistency, minimize conflict, and allow the child to maintain meaningful relationships with both parents when it is safe and appropriate to do so.
Physical Custody
Physical custody refers to where a child lives on a day-to-day basis, while parenting time describes the schedule that determines when each parent has time with the child. Courts address physical custody and parenting time together, with the goal of supporting the child’s stability, routine, and ongoing relationships.
Michigan courts may award joint physical custody, where a child spends significant time living with each parent, or sole physical custody, where the child primarily resides with one parent and the other parent is granted parenting time. There is no single default arrangement. Courts tailor physical custody and parenting-time schedules to fit the child’s age, developmental needs, and family circumstances.
​
When evaluating physical custody and parenting time, courts look at whether a proposed schedule:
​
-
Supports consistency in the child’s daily life
-
Fits the child’s school, activities, and routines
-
Minimizes disruption and unnecessary conflict
-
Allows for meaningful involvement by both parents, when appropriate
​
In practice, parenting-time arrangements in Michigan can take many forms, ranging from evenly shared schedules to more structured parenting time when one parent has primary physical custody. Courts focus less on labels and more on whether the arrangement promotes the child’s best interests, emotional security, and long-term well-being.
Legal Custody
Legal custody refers to a parent’s authority to make major decisions affecting a child’s life, including decisions about education, medical care, and religious upbringing. Courts address legal custody separately from physical custody and parenting time.
​
Michigan courts may award joint legal custody, in which both parents share decision-making authority, or sole legal custody, in which one parent has primary authority to make major decisions. Joint legal custody is common when parents are able to communicate and cooperate in a way that supports consistent, informed decision-making for the child.
​
When determining legal custody, courts focus less on how time is divided and more on how parents interact around important decisions. Courts often consider whether parents can share information, discuss major issues respectfully, and place the child’s needs ahead of conflict or disagreement.
​
Sole legal custody may be awarded when ongoing conflict, communication breakdowns, or safety concerns make shared decision-making impractical or harmful to the child. In those cases, courts aim to ensure that decisions affecting the child can be made clearly and consistently.
​
Regardless of how legal custody is allocated, Michigan courts prioritize arrangements that promote stability, reduce conflict, and support the child’s long-term well-being.
Court Expectations & Co-Parenting Responsibilities
Parents are expected to comply with court orders, communicate respectfully, and make reasonable efforts to support their child’s stability throughout the custody process and beyond. These expectations apply whether parents share custody or one parent is awarded primary physical custody.
​
Courts recognize that children generally benefit from predictability, consistent routines, and reduced exposure to adult conflict. Research in child development consistently shows that ongoing parental conflict can be more harmful to children than the specific structure of a parenting schedule. For this reason, Michigan courts pay close attention to how parents manage communication, transitions, and disagreements once a case is underway.
​
Courts often look at behavior such as:
​
-
How parents share information about the child’s education, health, and daily needs
-
Whether parenting-time schedules are followed consistently
-
How exchanges and transitions are handled
-
Whether parents support the child’s relationship with the other parent, when it is safe to do so
-
Whether adult conflict is kept separate from the child’s experience
​
Michigan courts do not expect parents to agree on every issue. Instead, the focus is on whether parents can communicate and function in a way that supports the child’s emotional security, minimizes disruption, and allows the child to maintain healthy relationships within a stable framework.

Parenting Plan Overview
Parenting plans are used to outline how parents will share parenting time and responsibilities moving forward. These plans are most common when parents share custody or are seeking a structured parenting-time arrangement that reflects the child’s daily needs and routines.
​
A parenting plan typically addresses schedules, transitions, holidays, and other practical considerations related to parenting time. While the plan may also touch on how parents communicate or resolve disagreements, Michigan courts focus primarily on whether the plan provides clarity, consistency, and stability for the child.
​
Parents may submit a parenting plan jointly when they are able to agree, or each parent may propose a plan for the court’s consideration. When reviewing proposed plans, courts evaluate whether the plan aligns with the child’s best interests and whether it is workable in practice.
Not every Michigan custody case requires a formal parenting plan. In some cases, the court may issue custody and parenting-time orders without adopting a detailed plan. When plans are used, their purpose is to reduce uncertainty, set clear expectations, and minimize future conflict around parenting time.
Creating a Parenting Plan
Parenting plans are not required in every custody case, but they are commonly used when parents want to propose a structured approach to parenting time and responsibilities. When parents are able to agree, a parenting plan can be submitted jointly for the court’s review. When parents do not agree, each parent may submit a proposed plan, or the court may issue custody and parenting-time orders without adopting a formal plan.
​
Courts evaluate parenting plans based on whether they are workable, child-focused, and consistent with the child’s best interests. Plans that reflect a child’s school schedule, daily routines, and developmental needs tend to be easier for courts to evaluate than plans that rely on assumptions about future cooperation or idealized arrangements.
​
Michigan courts look at whether the plan:
​
-
Clearly defines parenting-time schedules and transitions
-
Provides consistency and predictability for the child
-
Anticipates how parents will share information about the child
-
Minimizes opportunities for ongoing conflict
​
A parenting plan does not need to anticipate every future disagreement. Courts generally favor plans that provide clarity around day-to-day parenting while allowing flexibility as children grow and circumstances change.
Modifying a Parenting Plan
Parenting plans and custody orders in Michigan are not permanent. Changes to parenting plans are made through modification of the court’s child custody order, which governs custody and parenting-time arrangements. Courts recognize that children’s needs, family circumstances, and schedules often change over time, and custody or parenting-time arrangements may need to be adjusted as a result.
​
When a parenting plan is in place, a parent may ask the court to modify the plan if circumstances have changed in a way that affects the child’s well-being. Courts evaluate modification requests using the best interest of the child standard, with particular attention to whether the proposed change promotes stability and supports the child’s developmental needs.
​
Common reasons parents seek modification include changes in a child’s school schedule, relocation, shifts in a parent’s work availability, changes in the child’s developmental or medical needs, or ongoing conflict that interferes with effective co-parenting.
​
Court considerations when reviewing a request to modify a parenting plan:
​
-
Whether circumstances have changed in a meaningful way
-
How the proposed modification would affect the child’s routines and stability
-
Whether the change supports consistent, age-appropriate involvement by both parents, when appropriate
-
Whether the modification is likely to reduce or increase conflict
​
Parents are generally expected to follow the existing court order unless they reach an agreement that is approved by the court or the court issues a modified order.
Notes for Mothers
Mothers navigating custody matters in Michigan often do so during a period of meaningful change. Separation can reshape daily routines, caregiving responsibilities, and expectations that may have been in place for years. Courts recognize that these transitions can be challenging and focus on how parenting responsibilities will be shared moving forward in a way that supports the child’s stability and well-being.
​
Michigan courts evaluate custody arrangements based on the child’s best interests, with attention to how proposed schedules and decision-making structures function in practice. As roles evolve, courts consider how each parent supports the child’s emotional needs, maintains consistency, and adapts to new routines during times of change.
​
Mothers may find that clarity and predictability become increasingly important as families adjust. Parenting plans that provide structure, reduce conflict, and allow children to maintain meaningful relationships can help ease the transition for both parent and child when it is safe and appropriate to do so.
Custody proceedings can be emotionally demanding, particularly when familiar roles are changing. Understanding how courts approach these decisions may help mothers navigate the process with greater clarity while keeping the focus on their child’s long-term well-being.
Notes for Fathers
Fathers navigating custody matters in Michigan often do so during a time of uncertainty and adjustment. Separation can change daily contact with a child, disrupt familiar routines, and require fathers to redefine how they show up in their child’s life moving forward. Courts recognize that these transitions can be challenging and focus on arrangements that support the child’s stability and ongoing needs.
​
Michigan courts evaluate custody based on the child’s best interests, with attention to how parenting responsibilities are carried out in practice. As schedules and roles evolve, courts consider a parent’s consistency, reliability, and ability to meet the child’s emotional and developmental needs within the proposed arrangement.
​
Fathers may find that adapting to new parenting rhythms takes time. Clear parenting plans, predictable routines, and steady engagement can help support a child through these changes while preserving meaningful connections when it is safe and appropriate to do so.
​
Custody proceedings can be emotionally demanding, particularly when a father’s role is shifting or still taking shape. Understanding how courts approach these decisions may help fathers navigate the process with greater clarity while remaining focused on maintaining a stable and supportive relationship with their child.
Breastfeeding Considerations
Courts recognize that breastfeeding can be an important aspect of an infant’s care, particularly during early development. When breastfeeding is ongoing, courts may take it into account when establishing or adjusting parenting-time schedules, especially where feeding frequency or the child’s age makes extended separations impractical.
​
At the same time, breastfeeding does not automatically determine custody outcomes. Michigan courts continue to apply the best interest of the child standard and consider how parenting-time arrangements can support both the child’s nutritional needs and the development of a secure, meaningful relationship with each parent.
​
Courts often look at whether parenting-time schedules can be structured in a way that:
​
-
Supports the child’s health and feeding needs
-
Allows for age-appropriate bonding with both parents
-
Adapts as the child grows and feeding patterns change
-
Promotes cooperation and minimizes conflict
​
As children mature and feeding needs evolve, Michigan courts may revisit parenting-time arrangements to reflect the child’s changing development. The emphasis is typically on flexibility, stability, and ensuring that schedules remain responsive to the child’s needs rather than fixed to a particular stage.
Michigan Family Law & Statutes
Child custody and parenting time in Michigan are governed primarily by the Michigan Child Custody Act of 1970, along with related provisions addressing parenting time, jurisdiction, and modification of custody orders.
Key statutes that commonly apply in Michigan custody cases include:
​
Michigan Compiled Laws § 722.23
Establishes the best interest of the child factors used in custody determinations.
Michigan Compiled Laws § 722.26a
Addresses joint custody, including factors courts consider when deciding whether joint custody is appropriate.
Michigan Compiled Laws § 722.27
Governs custody orders, parenting time, and the court’s authority to modify child custody orders.
Michigan Compiled Laws § 722.27a
Addresses parenting time, including factors courts consider when establishing or modifying parenting-time schedules.
Michigan Compiled Laws § 722.28
Sets standards for reviewing and modifying custody orders, emphasizing stability for the child.
​
These statutes form the legal framework Michigan courts rely on when issuing and modifying child custody orders, determining parenting time, and applying the best interest of the child standard. Courts also rely on case law interpreting these provisions and the specific facts of each family’s situation.
