Shared Expenses

What It Means

Shared expenses are the recurring and one-time costs associated with owning and maintaining a co-owned property, split among co-owners according to the terms defined in the Co-ownership Agreement. Common shared expenses include mortgage payments, property taxes, homeowners insurance, utilities, HOA fees, routine maintenance, and major repairs.

​

How shared expenses are allocated is one of the most operationally important decisions in co-ownership. The allocation may follow Ownership Shares, be split equally regardless of ownership percentage, or follow a custom arrangement that accounts for factors such as occupancy, income, or use of specific areas of the property.

How Expense Sharing Works

The Co-ownership Agreement should define which costs are shared, the allocation formula for each category, the payment schedule and method, and the process for handling unexpected expenses — such as emergency repairs or special assessments. It should also address what happens when a co-owner fails to pay their share, linking to the Default provisions in the agreement.

​

Expense allocation does not need to be uniform across all categories. For example, co-owners may agree to split the mortgage based on ownership percentage, split utilities equally, and allocate maintenance costs based on occupancy. The key is that every category is defined in writing before closing.

Why It Matters for Co-owners

Shared expense disputes are among the most frequent sources of friction in co-ownership — particularly when one co-owner feels they are paying more than their fair share or when unexpected costs arise without a predefined allocation process. These disputes can erode trust quickly and, if unresolved, escalate to the point where a co-owner seeks to exit or initiates a Partition Action.

​

It is important to understand that expense contributions and Ownership Share are not the same thing. A co-owner who pays 50% of the monthly mortgage does not necessarily hold a 50% ownership interest. The ownership percentage is recorded on the Deed; the expense split is governed by the Co-ownership Agreement. These should be coordinated but are legally independent.

• Allocation may follow ownership percentages, be split equally, or use a custom arrangement
• Expense contributions are legally distinct from ownership percentage
• The agreement should define allocation for every cost category and address missed payments
• Expense disputes are among the most common sources of co-ownership friction
