A parent arrives at a first consultation with a folder of text messages, a calendar of missed pickups, and three years of bank statements. Some of it will matter a great deal. Much of it will not. Part of a family lawyer’s job is sorting one from the other, and doing it in a way that matches what the court will actually be asked to decide.
This article walks through how attorneys review the facts in a divorce or custody case, using Oregon and Washington law as examples. The process is similar in other states, but the legal tests that give facts their weight are set by each state’s statutes.
Start With the Legal Question, Not the Pile of Documents
Facts only matter in relation to the question the court has to answer. In a divorce, that is usually how to divide property and debt, whether support is owed, and, if there are children, what parenting arrangement serves them best. An attorney identifies those questions first, then reads the evidence against them.
The statutes supply the checklist. When Oregon courts decide custody, ORS 107.137 directs them to weigh factors such as the child’s emotional ties to family members, each parent’s interest in and attitude toward the child, the value of continuing existing relationships, any abuse by one parent, a preference for a fit primary caregiver, and each parent’s willingness to support the child’s relationship with the other. In Washington, RCW 26.09.187 lists factors for the residential schedule and says the strength and stability of the child’s relationship with each parent gets the greatest weight.
| Question the court decides | Oregon | Washington |
| Custody and parenting time | Best-interest factors, ORS 107.137 | Parenting plan factors, RCW 26.09.187; limitations, RCW 26.09.191 |
| Property division | “Just and proper,” with a presumption of equal contribution to marital assets, ORS 107.105 | “Just and equitable” division of community and separate property, RCW 26.09.080 |
| Financial disclosure | Required documents within 30 days of request, ORS 107.089 | Financial declarations and discovery under court rules |
A message about who drove the children to school may seem trivial on its own. Against Washington’s focus on who performs daily parenting functions, it can be important evidence.
Build the Timeline
Many family law questions turn on when something happened. Dates show patterns, such as which parent handled medical appointments over several years, and they can change legal outcomes directly.
Washington offers a clear example. Under RCW 26.16.140, once spouses are living separate and apart, each spouse’s earnings and accumulations are generally that spouse’s separate property. Pinning down the date of separation can therefore decide whether a bonus, a retirement contribution, or a new account is shared or separate. Attorneys compare leases, mail, bank records, and messages to establish that date, and they flag records that conflict.
Gaps matter too. An event described without a date, or two documents that place the same event at different times, does not answer a legal question by itself, but it shows where more digging is needed before anyone relies on it.
Compare Accounts Against Records
Two parents can honestly describe the same weekend in completely different ways. Instead of choosing one version, an attorney tests each account against what can be documented: school attendance records, medical visits, calendars, photos, and messages.
Those records also have to be usable in court. Text messages and social media posts must be authenticated, meaning there must be evidence they are what they appear to be, under Oregon Evidence Code Rule 901 (ORS 40.505) and the similar Washington rule. Screenshots without context, or messages from an account whose owner is disputed, can carry less weight than a client expects.
When the accounts are sharply opposed and the children’s welfare is at stake, a court may order a custody evaluation. In Oregon, ORS 107.425 allows the court to order an independent investigation or evaluation, giving the judge a neutral professional’s view of the family.
Separate Facts From Assumptions
Divorce is emotional, and assumptions harden quickly into “facts.” A parent may be certain the other parent is hiding income, or that a new partner is a bad influence. An attorney sorts each claim into what is documented, what is reported by someone else, and what is a suspicion that still needs support.
That sorting matters because courts decide on evidence. It also protects the client: building a case around an allegation that turns out to be wrong can damage credibility on every other issue.
Look for What Is Missing
Missing information can matter as much as what is in the file. In an Oregon divorce, ORS 107.089 lets a party request core financial documents, including three years of tax returns, recent financial statements, debt statements, and retirement account statements, which must be produced within 30 days. A spouse who does not respond can be compelled by the court, and a willful failure can lead to an order to pay the other side’s attorney fees.
For custody, the missing piece might be a school record, a counselor’s report, or a message thread that one parent described but did not provide. Procedural gaps matter as well: a party who was never properly served or notified can find an order entered without them. Findattorneys.org’s explanation of how legal notices work in family law disputes covers why that step matters.
Weigh the Details Together
No single fact usually decides a family law case. A missed exchange means one thing if it happened once during a snowstorm, and something else if it fits a pattern documented over two years. A large withdrawal from a joint account means one thing if it paid the mortgage, and another if it went to a new apartment.
Reviewing the evidence as a connected set is often what turns a disorganized file into a clear presentation, and it is also how a skilled attorney at Pacific Cascade Legal or any experienced family lawyer can tell a client honestly which issues are worth contesting and which are better settled. Many cases resolve through negotiation or mediation once both sides see the same organized record; findattorneys.org’s overview of divorce mediation explains when that approach fits.
Where the Law Limits the Analysis
Some facts change the framework entirely. In Oregon, a finding that a parent committed abuse creates a rebuttable presumption that it is not in the child’s best interest for that parent to have sole or joint custody, under ORS 107.137(2). In Washington, RCW 26.09.191 requires the court to limit a parent’s residential time and decision-making when certain findings are made, such as a history of domestic violence. Oregon law also bars a court from preferring either parent based on sex alone. Because these rules can outweigh everything else in the file, attorneys check for them early.
Frequently Asked Questions
What evidence matters most in a custody case?
Evidence tied to the statutory factors, especially who has performed day-to-day parenting and the strength of each parent’s relationship with the child.
Are text messages admissible in a divorce?
Often yes, if they are relevant and properly authenticated. Context and proof of who sent them matter.
What financial documents are exchanged in an Oregon divorce?
Under ORS 107.089, either party can request tax returns, financial statements, debt and account records, and retirement statements, due within 30 days.
Does the date of separation matter in Washington?
Yes. Earnings and accumulations after spouses begin living separate and apart are generally separate property.
