Your question, explained
You file where YOU and the child live — not where the biological parent lives. If you live in another state but the biological parent is in Oklahoma, the adoption is filed in YOUR state, not Oklahoma.
However, if you and the child live in Oklahoma:
- You file in Oklahoma District Court
- The biological parent can be served anywhere — in Oklahoma or in another state
- The adoption follows Oklahoma law regardless of where the other parent lives
- 6 months residency required (10 O.S. § 7503-1.1)
If the biological parent lives in Oklahoma and you live elsewhere:
- You file in YOUR state's court
- The biological parent is served at their Oklahoma address
- Oklahoma's laws do not govern — your state's laws do
- Contact us and we'll prepare documents for your state
Cross-state service of process:
- A sheriff or process server in Oklahoma can serve the biological parent
- If the parent is cooperative, they can sign consent and have it notarized in Oklahoma
- If the parent's location in Oklahoma is unknown, service by publication may be used
Cost: $349 regardless of which state | Call (855) 924-0450 to discuss your multi-state situation.
