Find the office that answers your question
Start with the kind of record or issue you have: an assessed value goes to Assessment; a delinquent property-tax claim goes to Tax Claims; and a court-record question starts with Court Administration. The links below are Northumberland County offices. Check the actual address or parcel with the office before relying on a record.
Sunbury city is in Northumberland County. A nearby office is not automatically the right office for a property, and a county record question is different from a city-specific question.

Official Northumberland County Court Administration websiteRules that can change the next step
Assessment and delinquent taxes are separate
Use the Assessment Office for an assessed-value question and Tax Claims for a delinquent property-tax claim or county tax-sale question.
A deed and a court judgment are different records
Confirm through Northumberland County’s official pages which office handles the specific record. Do not assume one record search covers both.
A mortgage sale is not a tax sale
For a mortgage foreclosure or sheriff-sale notice, use the lender, court, or sheriff contact named on that notice. Use Tax Claims for a county tax-claim or tax-sale question.

Sunbury and Northumberland County resource questions
Which Northumberland County office handles an assessed-value question?
Start with the Northumberland County Assessment Office for an assessed-value or county assessment-record question. A delinquent property-tax claim is a separate question for Tax Claims.
Where should I ask about delinquent property taxes or a tax sale?
Contact Northumberland County Tax Claims about a delinquent property-tax claim or tax-sale question. Assessment is a different office and answers a different kind of question.
Are deed and court-judgment records the same?
No. They are different record questions. Use Northumberland County’s official pages to confirm which office handles your specific deed or court record; do not assume one record search covers both.
Does Tax Claims handle a mortgage foreclosure or sheriff-sale notice?
No. A mortgage foreclosure or sheriff-sale notice is separate from a county tax-sale matter. Use the lender, court, or sheriff contact named on the mortgage notice; contact Tax Claims about a county delinquent-tax claim or tax-sale question.
How do I check which county office covers my actual property?
These links go to Northumberland County offices. Give the relevant office the property address or parcel number and ask it to confirm the correct jurisdiction and record. Do not assume a nearby office covers the property.
