Oregon Best Interests of the Child: How Judges Decide Custody Under ORS 107.137

When Oregon parents can't agree on custody, a judge decides for them. That decision isn't arbitrary — it follows a specific statutory framework laid out in ORS 107.137, and understanding exactly what judges evaluate gives you a concrete advantage in mediation and in court.

Here's what the statute actually says and how each factor plays out in practice.

The Six Statutory Factors

1. Emotional Ties

The court examines the depth and quality of the child's emotional bonds with each parent, siblings, and extended family. This isn't about who the child "likes more" — it's about established psychological attachment patterns.

Evidence that strengthens this factor: consistent involvement in bedtime routines, emotional comforting during illness or distress, and maintaining relationships with the child's broader support network (grandparents, cousins, close family friends).

2. Interest and Attitude Toward the Child

Judges distinguish between parents who actively prioritize the child's daily needs and those who treat custody as a proprietary right. This factor looks at hands-on parenting history — who attends school conferences, schedules medical appointments, manages homework, and handles the unglamorous daily logistics.

A parent who has been disengaged during the marriage can't suddenly claim equal involvement at the custody hearing. Courts look at the pattern over time, not the last three months of effort.

3. Continuity and Stability

Oregon courts strongly prefer maintaining stability. If the child is thriving in their current school, neighborhood, and social environment, the court will weigh disruption heavily against any proposed change. This factor is why the parent who stays in the family home often has a structural advantage — they're offering the child the status quo.

4. Abuse History

This is the factor with the sharpest teeth. Under ORS 107.137(2), if a parent has committed "abuse" — defined as physical injury, fear of imminent physical injury, or forced sexual relations — a rebuttable presumption triggers against awarding custody to that parent.

The presumption means the abusive parent starts at a deficit and must affirmatively overcome it with evidence. Documented protective orders, police reports, and Family Abuse Prevention Act (FAPA) restraining orders carry significant weight.

5. Primary Caregiver Preference

If the court identifies a fit primary caregiver — the parent who has historically managed daily nutrition, medical care, school involvement, and emotional comforting — there's a statutory preference for maintaining that arrangement.

This factor doesn't create an automatic win, but it creates momentum. The parent who can demonstrate a consistent track record of hands-on caregiving has a meaningful advantage under this framework.

6. Willingness to Facilitate the Other Parent's Relationship

Courts measure whether each parent actively encourages the child's relationship with the other parent. A parent who badmouths the other parent in front of the child, interferes with scheduled parenting time, or attempts to alienate the child will face negative judicial scrutiny.

There's an important safety exception: the court cannot penalize a parent for being unwilling to facilitate contact if they can demonstrate that the other parent has engaged in a pattern of abuse or sexual assault that poses a risk to the child or the protective parent.

What Courts Cannot Consider

ORS 107.137 also sets clear boundaries on judicial discretion:

• Gender — The court is explicitly prohibited from preferring one parent based on sex. Mothers and fathers receive identical treatment under the statute.
• Disability — A parent's physical or mental disability cannot be used against them unless specific findings show the disability creates an active danger to the child.
• Lifestyle — A parent's marital status, income level, social environment, or lifestyle choices are irrelevant unless there's direct evidence they cause physical or emotional damage to the child.

How to Strengthen Your Position

Understanding these factors is the first step. The next is organizing your evidence around them. Document your involvement in daily caregiving. Keep records of school engagement, medical appointments you've attended, and your child's extracurricular schedule. Show a pattern of cooperative, child-focused parenting.

The Oregon Child Custody & Parenting Plan Guide includes a best-interests self-assessment worksheet that maps your evidence to each ORS 107.137 factor, helping you build a structured case for mediation or court.
