Two people own a property together, but only one of them pays to improve it.
Maybe one co-owner renovated the kitchen, replaced the roof, finished the basement, installed new windows, or spent substantial money updating the property before the relationship between the owners broke down.
If the property is later sold in a New York partition action, that owner will often ask:
Do I get my renovation money back before we divide the proceeds?
Potentially—but not automatically.
A New York partition action is equitable in nature. That means the court is not limited to simply looking at the percentages on the deed and dividing the remaining money mechanically. An accounting can be used to determine the parties’ financial rights and whether adjustments should be made before the proceeds are distributed.
Renovations and improvements can be part of that analysis, but the person seeking a credit generally needs evidence supporting both the expenditures and the claim that equity requires an adjustment.
A 50/50 Deed Does Not Always Mean Every Expense Is Shared 50/50Suppose two co-owners each hold a 50% interest in a house.
One owner spends $75,000 renovating the property while the other contributes nothing. Years later, the property is sold through a partition action.
It may seem obvious to the paying owner that the first $75,000 should simply be returned before the remaining proceeds are divided.
New York law is more fact-specific.
Partition is an equitable remedy, and courts may adjust the parties’ rights when determining the proper distribution of sale proceeds. The Second Department recently reiterated that an accounting is a necessary incident of a partition action because the parties’ respective equities must be considered. See Hamilton v. Hamilton, 2026 NY Slip Op 04752.
But an equitable accounting is not the same thing as an automatic reimbursement system.
Can Renovations Actually Affect the Final Distribution?
Yes.
New York appellate decisions recognize that financial contributions toward jointly owned property—including substantial renovations—can be relevant when determining the parties’ equitable interests.
For example, in Gulick v. Beckett, the First Department considered that one party had made nearly all of the financial contributions toward the property, including carrying costs, mortgage payments, and extensive renovations, when evaluating the parties’ respective interests.
The important point is not that every renovation invoice creates a dollar-for-dollar credit.
Rather, renovation expenditures can become part of the larger equitable accounting.
Depending on the circumstances, the court may consider who paid for the work, the nature of the work, the parties’ agreements and expectations, and the extent to which those expenditures affected the parties’ economic interests in the property.
Proof Matters
A renovation claim can fail even where a co-owner says substantial money was spent.
In Kiernan v. Martin, the Second Department affirmed a distribution that did not give one co-owner additional credit for alleged mortgage, tax, and improvement expenses because the claimant failed to substantiate the requested reimbursement through the trial testimony and documentary evidence.
That makes recordkeeping particularly important.
Useful evidence may include:
- Contractor agreements and invoices
- Receipts for materials
- Canceled checks and bank statements
- Credit-card statements
- Permits and inspection records
- Photographs showing the work
- Appraisals
- Emails or text messages between the co-owners discussing the project
- Evidence showing how the renovation affected the property
A homeowner who paid contractors in cash and kept no records may face a much more difficult accounting years later.
What If the Other Co-Owner Agreed to the Renovation?
Agreements between co-owners can matter significantly.
The agreement does not necessarily need to look like a formal construction contract. Communications between the parties may become relevant to whether both owners understood that a renovation would be performed, how it would be paid for, and whether reimbursement was expected.
Conversely, a co-owner who voluntarily undertook expensive work without consulting the other owner should not assume that every dollar will later be reimbursed.
In Turrisi v. Severino, the Second Department emphasized that agreements between co-tenants should be respected when the court adjusts the equities in a partition action. The court also noted that voluntary payments made without an expectation of reimbursement generally are not refundable upon partition.
That principle can become important when the parties have very different recollections about why the work was performed.
Is Replacing a Roof the Same as Building a Luxury Kitchen?
Not necessarily.
The facts surrounding the expenditure matter.
Some work may be necessary to preserve the property—for example, repairing a leaking roof or addressing serious structural damage.
Other expenditures may be elective improvements made primarily because one owner preferred them.
That distinction does not create a simple rule that all necessary repairs are reimbursed and all elective upgrades are not. But the reason for the expenditure can be relevant to the equitable accounting.
A court evaluating a renovation claim is looking at the overall equities between the co-owners, not merely totaling receipts.
Does the Renovation Have to Increase the Property’s Value?
The effect of the work on the property’s value can be important.
A co-owner who spends $100,000 on improvements should not necessarily assume that the property became $100,000 more valuable.
Some improvements add substantial market value. Others may add relatively little. Some may even reflect personal preferences that a future buyer does not value at all.
Evidence concerning the property’s condition before and after the work—and in an appropriate case appraisal evidence—may therefore become relevant.
The ultimate question is not simply “How much did I spend?”
It is “What adjustment, if any, should be made between the co-owners when the court determines their respective financial rights?”
The Bottom Line
If you paid for renovations or improvements to jointly owned New York property, those expenditures may affect the accounting in a later partition action.
But reimbursement is not automatic.
The court can consider the parties’ contributions and other equitable circumstances when determining how sale proceeds should ultimately be distributed. The strength of a renovation claim may depend heavily on documentation, the nature of the work, agreements between the co-owners, and the evidence supporting the requested adjustment.
A co-owner who is spending substantial money on jointly owned property should therefore keep detailed records before a dispute arises.
When a partition case eventually becomes a disagreement over who gets what, proving what happened years earlier can be just as important as proving who owns the property.
