How to Prove House Expenses in an Oregon Partition Case

Short answer: In an Oregon partition action you prove expenses on the property with contemporaneous documentation that ties payments to the property (receipts, invoices, cancelled checks, bank or credit-card statements, mortgage/tax/HOA bills, permits, contractor contracts), supported by photos, contractor affidavits, and a clear accounting. The court will credit or charge co‑owners based on evidence that a payment was made and benefited the property. See Oregon’s partition statutes in ORS Chapter 105 for how the court handles partition and accounting: https://www.oregonlegislature.gov/bills_laws/ors/ors105.html.

Detailed answer

Partition cases in Oregon (ORS Chapter 105) let co‑owners ask the court to divide or sell property and settle who paid what. When one party asks the court to credit them for expenses (repairs, improvements, taxes, mortgage, utilities), the court needs proof. The party seeking credit has the burden to show:

That the expense was actually paid;
That the payment was for the property at issue (not personal living costs); and
That the expense either preserved or improved the property or was otherwise necessary.

Key types of paperwork and evidence that courts commonly accept:

Receipts and invoices from contractors, suppliers, or stores showing the work or materials, dates, amounts, and the property address.
Cancelled checks or cleared online banking records showing payee, date, and amount.
Bank and credit‑card statements that show the payment. If you rely on statements printouts, be prepared to authenticate them (see tips below).
Paid contractor contracts that show scope of work and the agreed price, plus proof of payment (check stub, payment receipt, or ACH record).
Building permits and inspection records connected to the work. Permits show the work was authorized and tied to the property.
Photographs taken before, during, and after the work to show necessity or improvement.
Property tax, mortgage, and HOA statements showing payments that relate to the property.
Appraisals or repair estimates that can help quantify how an improvement changed value.
Affidavits or declarations from the payer, contractor, or other witnesses describing payment and work performed (signed under penalty of perjury).

How the court typically treats different documents:

Direct payment proof (cancelled checks, bank records with payee) is strong evidence of payment.
Receipts and invoices are necessary to show what was bought or done. A receipt without proof of payment is weaker—show both if possible.
Photographs and permits help show the nature and scope of work and that it benefited the property.
Business records (contractor invoices, store receipts) usually must be authenticated. A contractor’s affidavit or testimony can authenticate those records.
If you lack an original receipt, contemporaneous bank/credit records, cancelled checks, or third‑party testimony can often substitute.

Typical categories of expenses and what to collect

Repairs and improvements: contractor invoice, paid check/ACH, permit, before/after photos, contractor license and affidavit.
Mortgage payments: mortgage statement showing account and payment history; cancelled checks or bank statements showing the actual payment.
Property taxes: tax bill and proof of payment (tax collector receipt, cancelled check, bank or escrow statement).
Utilities/insurance/HOA fees: billing statements plus proof of payment.

When you don’t have perfect paperwork

Missing a receipt does not automatically prevent recovery. Use alternative proofs:

Bank or credit‑card statements that show the merchant name and amount.
Cancelled checks or check images from your bank.
Vendor or contractor testimony or a signed affidavit that confirms services and payment.
Third‑party records such as payment app histories (PayPal, Venmo) or escrow/title closing statements.
Photographs, emails, texts, and permit records that corroborate the work and timing.

Practical steps to prepare your paperwork

Collect originals when possible. Keep copies of receipts, invoices, checks, bank statements, permits, and photos in one folder.
Create a simple accounting spreadsheet summarizing each expense: date, vendor, description, amount, payment proof, and how it benefited the property.
Get contractor affidavits or declarations that state they performed work and were paid (include dates and amounts).
Mark photos with dates and descriptions; keep metadata if available.
If the other side disputes the records, be prepared to authenticate documents with testimony or written affidavits or ask the court to compel production of underlying records.

How the court may resolve credits and reimbursements

Under ORS Chapter 105 the court will consider accounts of contributions and may:

Charge or allow credits to co‑owners for necessary expenses;
Order an accounting; or
Order sale of the property and distribute proceeds after adjustments.

Courts weigh whether payments were for ordinary maintenance (often shared) versus capital improvements (may increase value and be treated differently). Clear evidence that an expense improved or preserved value supports a reimbursement or credit against proceeds.

Discovery and subpoenas

If an opposing party will not produce records, you can request documents through discovery under Oregon civil procedure or seek subpoenas to obtain bank or third‑party records. If you need records from a financial institution or payment platform, plan to subpoena them or obtain certified copies through the institution’s records department.

When to get a lawyer

If the amount at stake is significant, the other side disputes payments, or records are complex or missing, consult an attorney experienced with Oregon partition actions. An attorney can help organize evidence, draft affidavits, serve discovery, and argue for credits in court.

Helpful Hints

Keep originals; courts and title companies like originals or certified copies.
Organize expenses chronologically and create a one‑page summary the judge can read quickly.
Match payments to invoices and photos so each line item shows proof, purpose, and benefit to the property.
Obtain contractor affidavits when possible to authenticate invoices and describe work.
If you pay with a credit card or bank transfer, retain the merchant descriptors and confirmation emails—these often authenticate payments.
If a payment came from a jointly held account, show authorization or intent to demonstrate which co‑owner advanced funds.
Consider a neutral appraisal if improvements materially change value; this helps the court allocate proceeds fairly.
Preserve text messages, emails, and other communications that discuss scope, price, and payment; they can corroborate claims.
