Maine's best-interest factors, laid out for actual use.

At different ages, stability, transitions, sleep, feeding, school readiness, peer ties, and separation tolerance can look very different. What helps a toddler regulate may not be what helps a teenager stay grounded.

• Age changes what "reasonable" looks like for schedule design and handoffs.
• Use examples from daily life, not broad labels about maturity.
• If the child is very young, frequent conflict and chaotic transitions often hit harder than abstract fairness arguments.

This factor is about who actually matters in the child's life: parents, siblings, grandparents, teachers, counselors, childcare providers, mentors, and anyone else with a meaningful role in the child's welfare.

• Strong, safe, stable relationships are protective for children under stress.
• Show who provides daily care, school support, appointments, and emotional steadiness.
• A court can only weigh relationships it can actually see.

A child's preference matters only if the child is old enough to express a meaningful preference. The point is not to put the child in charge. It is to take seriously what the child is actually experiencing.

• A child's stated preference should be evaluated in context, including age, stress, and possible pressure.
• Calm, consistent statements usually carry more weight than one dramatic moment.
• Do not turn this factor into a loyalty test.

This asks how long the child's current arrangement has lasted, whether it has been adequate, and whether continuity should be preserved. It is about lived reality, not theory.

• Continuity can protect sleep, schooling, treatment, friendships, and emotional regulation.
• A temporary arrangement that is chaotic or unsafe is not automatically a good continuity argument.
• Show the difference between mere familiarity and actual adequacy.

A proposal should be more than a preference. It should be workable. Housing, work schedules, transportation, childcare, distance, and backup plans all matter.

• A plan that sounds fair but falls apart every week may not support the child well.
• Courts often need real-world logistics, not just broad promises.
• Stable housing and predictable caregiving matter.

This factor looks at why the adults are asking for a given arrangement and whether they can actually provide warmth, direction, and steadiness for the child.

• Focus on parenting conduct, not self-description.
• Guidance includes boundaries, follow-through, and emotional availability.
• This factor is stronger when it is illustrated with patterns rather than slogans.

A child may be tied to a school, neighborhood, childcare setting, extended family network, activity, or treatment provider. Disrupting those ties can matter.

• School and community adjustment can be a major part of stability.
• The child's present functioning may reveal what is helping and what is not.
• Show both the benefits of continuity and the cost of change.

Maine policy generally values frequent and continuing contact with both parents, but safety and well-being stay primary. This factor is not a license to ignore abuse or real risk.

• Courts often look for whether a parent can support a child's relationship with the other parent.
• A true safety concern changes how this factor should be read.
• Do not blur safety evidence into ordinary scheduling friction.

Perfect harmony is not the test. The real question is whether the adults can exchange information, make basic decisions, and keep the child from carrying the conflict.

• Cooperation can be imperfect and still workable.
• The child should not be the message carrier.
• If cooperation is poor, explain whether structure or tools could improve it.

This factor asks what dispute-reduction methods exist and whether each parent is willing to use them. Parenting apps, written calendars, neutral exchange sites, mediation, and counseling may matter.

• The law is not limited to raw conflict; it can consider whether adults will use tools that reduce it.
• A workable communication method can matter as much as the adults' personal chemistry.
• The child benefits when conflict is structured away from daily life.

This is about what happens if one parent, rather than both, has sole authority over the child's upbringing. Some cases need one clear decision-maker in some areas; others do not.

• The goal is not to "win" authority for its own sake.
• The question is which decision structure best protects the child's well-being.
• Narrow, child-focused reasoning is stronger than broad control claims.

Maine expressly requires the court to consider domestic abuse and how it affects the child emotionally, the child's safety, and the other factors. Abuse is not a side note. It changes the meaning of the rest of the analysis.

• When abuse is present, safety cannot be treated as one equal factor among many.
• Exposure to violence can affect children directly and indirectly.
• The statute itself tells the court to read the rest of the factor list in light of abuse.

A history of child abuse is its own factor. It speaks directly to safety, trauma, trust, and the child's physical and psychological well-being.

• Child abuse history is not just "bad behavior" evidence; it is child-safety evidence.
• Specific dates, findings, reports, and treatment records matter more than broad accusations.
• If there is ongoing risk, use crisis and official-help doors first.

This is the catch-all for facts that do not fit neatly elsewhere but still matter to the child's physical or psychological well-being. Health, disability access, mental health, food, sleep, transport, supervision, and housing strain can all matter.

• This should not become a dump bucket for every grievance.
• Use it for facts with a clear connection to the child's well-being.
• Be explicit about the child impact, not just the adult frustration.

This factor exists, but the statute places a high bar on using it. It requires clear and convincing evidence, and the voluntary dismissal of a protection-from-abuse petition cannot, by itself, prove misuse.

• This factor is narrower than people often assume.
• Throwing it in carelessly can weaken the rest of the argument.
• If safety is real, safety remains primary.

For infants under one year old, feeding realities matter. The point is not ideology. It is to account for actual developmental and caregiving needs.

• Infant schedules can be driven by biology and caregiver logistics.
• This factor is limited, but it is explicit in the statute.
• Keep the explanation practical and child-centered.

A parent's conviction for a sex offense or sexually violent offense is an explicit factor because the safety implications can be profound.

• This is direct safety information, not just character evidence.
• Be accurate about the offense and status.
• If there is an immediate child-safety issue, move to emergency and official doors first.

Safety analysis does not stop with the parent. If someone living with a parent has certain sexual-offense history, that may matter to the child's safety and the proposed arrangement.

• The court can look at the environment around the child, not only the named parties.
• This is another factor where accuracy matters more than rhetoric.
• Tie the fact to actual child safety and supervision realities.

This is the bottom-line question: which allocation of parental rights and responsibilities best supports the child's safety and well-being. It pulls the whole analysis together.

• This is where the child-centered theory of the case should become clear.
• If your reasoning on A through R is coherent, S should read like the natural conclusion.
• Do not make S broader than the evidence you can actually show.
