Oregon Child Custody Laws: How Custody Is Decided

In Oregon, a judge decides child custody based on the "best interests and welfare of the child," weighing a specific list of factors — with no single factor controlling the outcome. Oregon does not favor mothers over fathers or fathers over mothers, and a court cannot order joint custody unless both parents agree to it. If one parent has committed abuse, Oregon law creates a rebuttable presumption against giving that parent sole or joint custody.

How Oregon judges decide custody

Oregon law directs courts to award custody based on the best interests and welfare of the child. To make that determination, the court considers a set of factors, and importantly, no single factor is allowed to control the decision on its own. Under ORS 107.137(1), those factors include:

• The emotional ties between the child and other family members
• Each parent's interest in and attitude toward the child
• The desirability of continuing an existing relationship the child already has
• Whether either parent has abused the other parent
• A preference for a fit primary caregiver, where appropriate
• Each parent's willingness to facilitate a close and continuing relationship between the child and the other parent

The court weighs all of these together — there is no formula that automatically hands custody to one parent based on a single fact, such as who earns more or who moved out of the family home. Oregon law also expressly states that no preference may be given to a parent based on that parent's sex: a mother does not get preference because she is the mother, and a father does not get preference because he is the father (ORS 107.137(5)).

The abuse presumption — flagged as important

If a parent has committed abuse as defined in ORS 107.705, Oregon law creates a rebuttable presumption that awarding that parent sole or joint custody is not in the child's best interests (ORS 107.137(2)). "Rebuttable" means the presumption can be overcome with evidence, but it starts the analysis strongly against custody for a parent with a history of abuse. If domestic violence is part of your situation, this presumption is one of the most important things to raise with the court, and it may also affect parenting time and safety planning. Separately, a valid protection order is enforceable across state lines nationwide under federal law (the Violence Against Women Act, 18 U.S.C. § 2265), which matters if a parent or child later moves to or from Oregon.

Joint custody requires both parents to agree

An Oregon court cannot order joint legal custody unless both parents agree to it (ORS 107.169). If parents cannot agree, the court will award sole custody to one parent based on the best-interests factors above. This rule also matters after a divorce is final: if parents who had joint custody later become unable or unwilling to cooperate with each other, that breakdown in cooperation can itself count as a change of circumstances that justifies modifying the custody order.

Modifying an existing custody order

Custody orders are not necessarily permanent. Under ORS 107.135, a parent can ask the court to modify custody, but only by showing (1) a substantial change of circumstances since the last order, and (2) that the requested change is in the child's best interests. Both parts generally must be shown — a change alone is not enough if it would not benefit the child. Oregon law recognizes that repeated, unreasonable interference with the other parent's parenting time can itself be treated as a substantial change of circumstances supporting modification. If a parent is regularly blocking scheduled parenting time without a good reason, that pattern — not just a single missed visit — is what courts look at.

Moving with your child — the 60-mile notice rule (time-sensitive)

If you have a custody or parenting-time order and you want to move, Oregon law requires advance notice in certain situations. A parent may not move to a residence located more than 60 miles farther distant from the other parent without giving the other parent reasonable notice of the change of residence, and providing a copy of that notice to the court (ORS 107.159). This requirement can be suspended for good cause, such as a safety concern, but the default rule is notice first. Because missing this notice can create real complications in a later dispute, treat any long-distance move as time-sensitive and confirm the current notice procedure with your Oregon court before you move.

Can you file for custody or divorce in Oregon? Residency and jurisdiction

Two different residency-type rules can come up, and they are not the same thing:

• Filing for divorce: Generally, at least one spouse must have been a resident of or domiciled in Oregon continuously for six months immediately before filing, when the marriage was not solemnized (performed) in Oregon (ORS 107.075).
• Custody jurisdiction: Oregon has adopted the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) at ORS 109.701 to 109.834. Under this framework, a child's "home state" — generally where the child has lived for the six months before the custody case is filed — is usually the state with authority to make the initial custody decision. The UCCJEA has been adopted in some form by 49 states and the District of Columbia, which is designed to prevent competing custody orders from different states.

Federal law backs this up. Under the Parental Kidnapping Prevention Act (28 U.S.C. § 1738A), every state must give full faith and credit to a custody order issued by the child's home state, and a second state generally cannot modify that order while the original state still has jurisdiction. Together, these rules are meant to stop a parent from "forum shopping" — moving a child to a new state to try to get a more favorable ruling there.

Special situations under federal law

A few situations bring in federal law on top of Oregon's custody rules:

• Native American children: The Indian Child Welfare Act (25 U.S.C. §§ 1901–1923) sets minimum federal standards for cases involving removal of a Native American child from their family, and for foster care, adoption, and termination proceedings. It gives tribes jurisdiction and a role in these cases, requires notice to the child's tribe, requires "active efforts" to keep the family together, imposes a heightened burden of proof, and sets placement preferences favoring relatives and tribal homes.
• International child abduction: If a child has been wrongfully taken to, or kept in, another country (or brought to the U.S. from another country), the International Child Abduction Remedies Act (22 U.S.C. § 9001 et seq.) implements the Hague Convention and provides a federal court process to seek the child's return to their country of habitual residence. This process decides return, not who should ultimately have custody.
• Military parents: Under the Servicemembers Civil Relief Act (50 U.S.C. § 3932), a servicemember whose military duties materially affect their ability to appear in court — including in a divorce, custody, or support case — can request a stay of at least 90 days. This is designed to prevent default judgments against a deployed or active-duty parent who cannot participate.

What you can do in Oregon

1. Confirm you're in the right court. Check that Oregon is the child's "home state" under the UCCJEA (generally six months of residence) before filing, or find out which state has jurisdiction if the child recently moved.
2. Gather evidence tied to the six factors. Document the child's relationships, your involvement in caregiving, school and medical records, and any history of abuse — this is what the court will actually weigh.
3. Decide whether joint custody is realistic. Since Oregon courts cannot order joint custody without both parents' agreement, think through whether you and the other parent can genuinely cooperate before requesting it.
4. Report abuse and safety concerns clearly. If ORS 107.705 abuse is present, raise it directly — it triggers a rebuttable presumption against custody for that parent and may support a protection order enforceable nationwide.
5. Give notice before a long-distance move. If you plan to move more than 60 miles farther from the other parent, provide reasonable notice to that parent and file a copy with the court — or ask the court about suspending the requirement for good cause.
6. Track interference with parenting time. Keep records if the other parent is repeatedly blocking scheduled time; a pattern can support a later modification request.
7. Confirm current numbers and deadlines with the court. Specific forms, fees, and local procedures vary and change; verify current requirements with the Oregon circuit court where your case is or will be filed.
