Understanding Illinois Partition Actions: When Co-Owners Can't Agree on Property Disposition

Posted by Melissa Rankine | Jun 13, 2025 | 0 Comments

When multiple people own property together, things can work smoothly for years—until they don't. Whether you're co-owners due to inheritance, business partnership gone wrong, or any other reason, disagreements about what to do with jointly owned property can become heated and seemingly impossible to resolve. That's where Illinois partition law comes in. If you're wondering whether you can force the sale of property you co-own, or if you're facing a partition lawsuit yourself, understanding this powerful legal remedy can help you navigate these challenging waters. 

 

What Exactly Is a Partition Action? 

A partition action is essentially a legal proceeding that allows co-owners of real estate to force the division or sale of property when they can't agree on what to do with it. Think of it as the legal system's solution to deadlock among property owners. 

Under Illinois law, any co-owner of real property has the right to seek partition, regardless of how small their ownership interest might be. Even if you own a mere 1% of a property, you're still entitled to a buyout. This process typically starts with negotiations and could lead to a sale through partition proceedings if an agreement isn't reached. This right is considered so fundamental that it generally cannot be waived permanently, even by contract. 

The concept behind partition law is straightforward: no one should be forced to remain in a property ownership relationship indefinitely against their will. If co-owners can't agree on how to use, manage, or dispose of property, the law provides a mechanism to resolve the impasse. 

 

Common Scenarios Leading to Partition Actions 

Partition actions arise in various situations, but several scenarios are particularly common in Illinois courts: 

Inherited Property Disputes: Perhaps the most frequent partition cases involve family members who inherit property together. For example, three siblings inherit the family home, but one wants to sell while the others want to keep it in the family. Or maybe one sibling has been living in the house rent-free while the others want to either collect rent or sell the property. 

Business Partnership Dissolution: When business partners who jointly own real estate can't agree on its disposition during partnership dissolution, partition may be necessary. This often happens with commercial properties or investment real estate owned through partnerships or LLCs. 

Investment Property Disagreements: Co-investors in real estate sometimes develop different visions for their property. One might want to sell and cash out, while another wants to continue holding for rental income or further appreciation. 

 

Types of Partition in Illinois 

Illinois recognizes two primary types of partition: partition in kind and partition by sale. 

Partition in Kind 

Partition in kind involves physically dividing the property among the co-owners. Each owner receives a separate portion of the property proportional to their ownership interest. For example, if three people each own one-third of a 30-acre parcel, partition in kind might result in each person receiving approximately 10 acres. 

However, partition in kind is only possible when the property can be physically divided without significantly diminishing its value. This works well for large tracts of undeveloped land that can be surveyed and divided into separate parcels. It rarely works for single-family homes, commercial buildings, or small lots where division would render the property useless or dramatically reduce its value. 

Partition by Sale 

Partition by sale is exactly what it sounds like—the court orders the property sold and the proceeds divided among the co-owners according to their ownership percentages. This is by far the more common outcome in Illinois partition actions, particularly for residential properties, commercial buildings, and smaller parcels of land. 

When ordering partition by sale, Illinois courts typically authorize either a public auction or private sale, depending on which method is likely to yield the highest price for the co-owners. The court may appoint a commissioner or receiver to handle the sale process, ensuring it's conducted fairly and in the best interests of all parties. 

 

Defenses and Limitations to Partition 

While the right to partition is generally considered absolute in Illinois, there are some defenses and limitations that can complicate or delay partition proceedings: 

Ouster Claims: If one co-owner has been excluded from using or occupying the property by another co-owner, they may have an "ouster" claim. This can result in the excluding party owing rent or other compensation to the excluded co-owner, which gets factored into the final accounting when the property is sold. 

Contribution Claims: Co-owners who have paid more than their share of property expenses (taxes, insurance, maintenance, improvements) may be entitled to contribution from other co-owners. These claims can complicate the partition proceeding as the court must sort out who owes what to whom. 

Improvements and Betterments: When one co-owner has made improvements to the property, questions arise about whether they should be compensated for adding value or charged for improvements that weren't agreed upon by all owners. Illinois law provides framework for addressing these issues, but they can significantly complicate partition proceedings. 

Homestead Rights: In some cases, a co-owner's homestead rights might complicate partition. If someone has been living on the property as their primary residence, they may have certain protections that need to be considered. 

 

Financial Considerations in Partition Actions 

Partition actions involve significant costs that are typically shared among all co-owners proportionally. These costs can include: 

  • Court filing fees and costs 

  • Commissioner fees for inspecting and appraising the property 

  • Receiver fees for handling the sale process 

  • Attorney's fees (though these are usually paid by each party individually) 

  • Real estate commission and closing costs if the property is sold 

  • Survey costs if partition in kind is attempted 

Before pursuing a partition, it's important to consider whether these costs might consume a significant portion of your expected proceeds from the property sale. 

 

Strategic Considerations for Co-Owners 

If you're considering filing a partition action, timing and strategy matter. Sometimes the mere threat of partition can motivate other co-owners to negotiate a buyout or agree to a voluntary sale. Other times, waiting for a better real estate market might maximize everyone's returns. 

It's also worth considering the relationships involved. Partition actions can permanently damage family relationships or business partnerships. While you have the legal right to force partition, considering the broader consequences is important. 

For those facing a partition action filed by another co-owner, remember that you have rights too. You can participate in the process to ensure the property is sold for fair market value, and you may have claims for contribution or compensation that should be addressed during the proceedings. 

 

Final Thoughts 

Partition actions serve an important function in Illinois real estate law by preventing co-owners from being trapped indefinitely in unwanted property relationships. While the right to partition is nearly absolute, the process can be complex, expensive, and emotionally challenging, particularly when family relationships are involved. 

If you're considering partition, start by having honest conversations with your co-owners about everyone's goals and concerns. Sometimes what appears to be a disagreement can be resolved through creative solutions that avoid the time, expense, and uncertainty of litigation. 

However, when co-owners truly cannot reach agreement, partition provides a valuable legal remedy that ensures no one remains trapped in an unwanted property ownership situation. The key is understanding the process, costs, and likely outcomes before proceeding, so you can make informed decisions about whether partition is the right solution for your situation. 

Whether you're contemplating filing a partition action or responding to one filed against you, consulting with an experienced real estate attorney is essential. These cases involve complex legal and practical considerations that can significantly impact your financial outcome. With proper legal guidance and realistic expectations about the process, partition can provide a fair resolution to property disputes that might otherwise remain deadlocked indefinitely. 

Remember that while partition actions can feel adversarial, they're ultimately about finding fair solutions when co-owners can't agree. Approaching the process with this perspective, rather than viewing it as a battle to be won, often leads to better outcomes for everyone involved.
