Co-Owned Property Division Lawsuits: Rights and Remedies

New York law recognizes three primary co-ownership structures: tenancy in common, joint tenancy with right of survivorship, and tenancy by the entirety. Tenancy in common allows owners to hold fractional, undivided interests that pass to heirs upon death. Joint tenancy includes rights of survivorship, transferring ownership automatically to surviving owners. Tenancy by the entirety applies exclusively to married couples with inherent survivorship rights.

Lawsuits between property co-owners stem from disagreements regarding property sale, unequal contribution to financial obligations, or unauthorized occupancy. Disagreements over capital repairs, property taxes, mortgage payments, or rental income distribution frequently escalate into litigation. When one co-owner refuses to sell or buy out another party's interest, filing a partition action becomes the legal recourse.

Partition actions allow co-owners to compel the division or sale of real property under Article 9 of the New York Real Property Actions and Proceedings Law. If co-owners executed a legal co-ownership agreement, non-compliance with maintenance terms or buyout provisions creates grounds for a breach of contract claim alongside the partition proceeding.

An accounting action requires a comprehensive judicial review of all income, expenditures, and financial transactions related to co-owned property. Co-owners who paid more than their proportional share of property taxes, mortgage payments, or necessary repairs can assert contribution claims to seek financial reimbursement during the final property division.

Every tenant in common or joint tenant holds an absolute statutory right to partition real property under New York RPAPL Article 9. This right ensures that no co-owner remains forced into joint property ownership indefinitely, provided the property is not held under a valid contractual waiver or specific statutory limitation.

Co-owners managing property rental income or operating funds owe fiduciary duties of honesty, full disclosure, and proper management to fellow co-tenants. Co-owners possess an equitable right to demand a judicial accounting and obtain reimbursement for necessary maintenance, tax payments, and property improvements upon sale or division.

Before initiating formal litigation, SJKP's attorneys send formal demand letters and initiate structured negotiations between co-owners. Pre-litigation steps involve reviewing title deeds, gathering financial records, organizing property appraisal reports, and exploring voluntary buyout agreements to avoid costly, extended court battles.

Litigation begins by filing a Summons and Complaint in the Supreme Court of the county where the real property is located. During discovery, parties exchange financial documents, bank statements, and appraisal evidence. If settlement efforts fail, the court issues a partition judgment ordering physical division or appointing a referee to conduct a public auction.

Determining fair market value requires independent certified real estate appraisals or court-appointed referee evaluations under New York civil procedure. Appraisers examine local real estate market comps, structural conditions, property improvements, and potential zoning restrictions to establish an objective valuation for court proceedings and settlement negotiations.

When physical division causes economic prejudice, courts order a judicial partition sale, distributing net proceeds proportionally after deducting legal costs and accounting adjustments. Alternatively, co-owners may execute a buyout agreement where one party purchases the remaining fractional shares based on court-approved appraisal valuations.

Property division lawsuits in New York typically take between 9 to 18 months to resolve through judgment. Litigation expenses include attorney fees, court filing fees, appraisal costs, and referee fees. Courts may order referee and appraisal fees paid directly from gross property sale proceeds.

Voluntary settlements provide co-owners with greater flexibility regarding sale timing, tax planning, and private buyout terms. Court judgments enforce strict statutory sales through public auction, which often yields lower sale prices than private market real estate transactions.
