Joint custody requires agreement
Under ORS 107.169, an Oregon court cannot impose joint legal custody over a parent's objection. If the parents do not agree, the judge must award sole custody to one of them.
That makes Oregon unusual: a contested case is often about who holds sole legal custody, not how to split it.
Custody and parenting time are separate
Custody in Oregon is about decision-making. Even a parent without sole custody usually has substantial parenting time. This is decided separately.
So "losing custody" is not the same as losing time with the child. Be clear about which you are focused on.
The best-interest factors
ORS 107.137 weighs the child's emotional ties, each parent's interest in and attitude toward the child, the desirability of continuing a current bond, any abuse, and โ importantly, which parent is more likely to support the child's bond with the other.
No single factor is used to the exclusion of the others.
What the numbers cannot show
The household shares above describe where Oregon children live, not who holds sole custody. Many families agree on arrangements without a contested trial.
Use the figures as context only. The factors and your evidence decide the case.
Building the record
Document the care you give and, because supporting the child's other bond is weighed, keep the messages that show how you cooperate. Log parenting time, exchanges and missed time with dates.
Casewell keeps those entries and files together. So an Oregon lawyer can review a clean record against ORS 107.137.
Does Oregon favor mothers?
No. Oregon put the answer directly into the custody statute.
No preference in custody shall be given to the mother over the father for the sole reason that she is the mother, nor shall any preference be given to the father over the mother for the sole reason that he is the father (ORS 107.137(5)).
The statute goes further in the other direction too. A parent's conduct, marital status, income, social environment or lifestyle counts only if it is shown to be causing or likely to cause the child emotional or physical damage.
That is worth knowing before you start a log. Details about the other parent's new relationship or spending are rarely the point. What happened to the child is.
The primary caregiver factor
One Oregon factor rewards day-to-day care by name. The statute lists "the preference for the primary caregiver of the child, if the caregiver is deemed fit by the court" among the things a judge weighs.
That is a question of fact, and it is answered with everyday detail. Who books and attends the appointments. Which parent does the school run and knows the teacher by name. Who the school calls when the child is ill.
No single factor decides an Oregon case, and the statute says so plainly. But a dated record of routine care is one of the few things that answers this factor directly.
Before you file in Oregon
Save any current order, track parenting time for a few weeks, and write the custody and parenting-time arrangement you want reviewed.
An Oregon family-law lawyer can weigh it against the statute and your county's practice before filing.

Does Oregon favor the mother in custody cases?
No. ORS 107.137(5) gives no preference to the mother just because she is the mother. It gives none to the father just because he is the father.
Can an Oregon court order joint custody if I disagree?
No. Under ORS 107.169 a court cannot order joint custody unless both parents agree to its terms. If you already share joint custody, an inability or unwillingness to keep cooperating can itself be a change of circumstances that supports changing the order.
Does Oregon publish a full-custody success rate?
No. Public data does not give a complete percentage of Oregon cases in which mothers or fathers receive sole legal and physical custody. Household statistics describe where children live, not court outcomes.
Do these statistics show that mothers get custody more often in Oregon?
They show the sex of the household householder in a living-arrangement table. They do not show legal custody, parenting-time percentages, the reason for the arrangement, or whether a court was involved.
Can documentation improve my chances of custody?
Yes. Good records can definitely improve your chances. They help you arrive prepared with clear, dated evidence in the right format. They give your lawyer a head start, saving time and fees. They cannot guarantee an outcome, but they can strengthen your case.
What should I record first?
Start with the current arrangement, then record each material change with the date, what was expected, what you observed, the source, the child-related effect, your response, and the outcome. Use Casewell to keep the entry and supporting file together.
