How to document house expenses for a partition case in Missouri

Disclaimer: This is general information, not legal advice. For advice about your situation, consult a licensed attorney in Missouri.

Detailed answer — what paperwork proves house expenses in a Missouri partition action

In a partition action, the court sorts out ownership and money-related adjustments (credits, reimbursements, or accounting) between co-owners before dividing or selling the property. To obtain credits for money you paid for the house (repairs, improvements, taxes, insurance, mortgage payments, utilities, etc.), you must prove both that the expenditures occurred and what they were for. Good documentary proof makes the difference between getting credit and losing money.

Missouri law lets the court order an accounting and consider equities among owners in a partition action. See the Missouri partition statutes for the general framework: Mo. Rev. Stat. Chapter 527 (Partition).

Types of documents that commonly prove expenses

Original receipts and invoices: contractor receipts, hardware-store receipts, appliance invoices, estimates showing scope and cost.
Cancelled checks and bank transfers: front-and-back images of checks, or bank statements showing electronic payments.
Credit-card statements tied to receipts: statement + corresponding receipt or invoice that describes the work or items purchased.
Bank statements: to show payment origin, sequence, and totals. Highlight or annotate relevant entries to make review easier.
Contract or service agreements: signed contracts with contractors, handymen, roofers, plumbers, or companies who performed work.
Permits and inspection records: city/county permits and inspection records for permitted work (supports that work occurred and was authorized).
Photographs and before/after evidence: dated photos that match invoices and show the need and result of repairs or improvements.
Insurance claims and payments: insurance payout records and repair invoices tied to claims.
Property tax and mortgage records: tax bills and proof of payment; mortgage statements and proof of payments you made.
Receipts for routine expenses: utility bills, HOA fees, and other operating costs with proof of payment.
Affidavits or sworn statements: a short affidavit from you or a contractor verifying that a receipt is genuine or explaining missing originals.

How to organize and present the paperwork to the court

Create a clear accounting summary: a spreadsheet or ledger that lists each expense (date, payee, description, category—repair vs improvement, amount, and the supporting document reference).
Group supporting documents: for each line on the summary, include the corresponding receipt, invoice, check image, or statement copy. Number or tab them so the court and other parties can follow easily.
Make and bring originals: bring originals to hearings if possible. File copies with your pleadings and retain originals in case the opponent or court requests them.
Explain the purpose: for each expense, briefly note whether it was maintenance (routine, preserves value) or an improvement (adds value). This distinction can affect whether the court awards reimbursement or adjusts the division of proceeds.
Provide chain-of-custody or authenticity notes: if a bank or company keeps records electronically, include a short declaration explaining how the records were produced and why they’re authentic.

What to do if you lack originals

If originals are lost, produce secondary evidence (bank statement showing payment plus the vendor’s invoice). Attach an affidavit explaining why the original is unavailable.
Request duplicates from vendors, banks, credit card companies, or the court clerk. Banks and merchants often will reissue statements or receipts.
Consider subpoenas for bank records if the other owner refuses to provide relevant documents. The court can compel production during discovery in a partition case.

Common pitfalls to avoid

Submitting unorganized stacks of papers without a summary—this makes it harder for the judge to credit your claim.
Failing to tie payments to property expenses—personal spending on non-property items won’t be credited.
Mixing personal and property expenses without clear tracing—if funds were commingled, you may need to trace which payments funded property work.
No proof of payment—an invoice alone is weak unless paired with proof you paid it (check, bank record, or receipt).

Practical steps to take now

Collect and scan all receipts, invoices, canceled checks, and bank statements. Back them up securely.
Prepare a one-page summary of totals by category (repairs, improvements, taxes, insurance, mortgage payments) with citations to document tabs.
Obtain missing documents from banks, vendors, or the county (permits, tax payment records).
If needed, ask the court clerk or an attorney about discovery tools (subpoenas, interrogatories, requests for production) to get records from the other party or third parties.
Consult a Missouri attorney experienced in partition actions to review your proofs and help present them effectively in court.

Helpful hints

Label everything. Use tabs and a contents page so a judge can easily verify each claim.
Mark receipts with the property address, date, and a short note about the work performed.
Differentiate repairs (maintenance) from capital improvements—improvements are more likely to affect final sharing of proceeds.
File your accounting as part of your court pleadings and attach key documents as exhibits.
Keep a running construction log or diary for future projects: who did the work, when, for how much, and what permit numbers apply.
When in doubt, get sworn statements from contractors or vendors confirming work and payment amounts.
