Quick answer: the deadline that shapes the whole schedule is whichever of two dates arrives later — 4 months from the first publication of notice, or 30 days after an individually mailed notice to a known creditor. See the full Oregon probate timeline calculator for your specific estimate.
The core deadlines, in order
| Deadline | Oregon rule | Statute |
|---|---|---|
| Small Estate Affidavit eligible | 30 days after death | ORS 114.515 |
| PR diligent search for creditors | Within 3 months of appointment | ORS 115.003 |
| Individual notice to known creditors | Within 30 days after search period ends | ORS 115.003 |
| Inventory due | 90 days after appointment | ORS 113.165 |
| Creditor claim deadline | Later of 4 months from publication or 30 days after individual notice | ORS 115.005 |
| Proof of notice compliance filed with court | Within 60 days of claim period expiring | ORS 115.008 |
| Oregon estate tax return (if over $1M) | Form OR-706 within 12 months | ORS 118.010 |
Why a "later of" rule doesn't reward speed
The search duty comes before the notice duty
Oregon requires more upfront legwork than many states: the personal representative has 3 months from appointment to make a reasonably diligent effort to identify creditors, and then 30 days after that search period ends to individually notify anyone found. Only after both the publication and any required individual notices have gone out does the 4-month (or 30-day) claim clock have a fixed starting point.
