Commercial real estate disputes move fast — and the stakes are high. Whether you’re a small business owner locked in a lease dispute with your landlord, a contractor chasing an unpaid balance, or a buyer who discovered problems after closing, you need an attorney who understands Illinois commercial real estate law and can act decisively on your behalf.

Fitter Law represents startups, small businesses, and entrepreneurs in commercial real estate litigation across Chicago, Cook County, and throughout Illinois. We handle the full lifecycle of business property disputes — from pre-litigation demand letters and negotiation through filing in Illinois courts when necessary.

Commercial Real Estate Disputes We Handle

Commercial Lease Disputes

Commercial lease conflicts are among the most common — and most disruptive — legal problems small businesses face. A dispute with your landlord can threaten your operations, your employees, and your bottom line.

We represent tenants and landlords in matters including:

• Alleged lease defaults and wrongful termination of commercial tenancies
• Disputes over rent escalation, CAM charges, and operating expense calculations
• Buildout, tenant improvement, and landlord repair obligation disputes
• Subletting and assignment disagreements
• Commercial eviction defense and unlawful lockout claims
• Lease enforcement and breach of quiet enjoyment

Breach of Commercial Real Estate Contracts

When a purchase agreement, letter of intent, or commercial contract falls apart — whether a buyer walks away, a seller refuses to close, or a party misrepresents the property — you may have a viable breach of contract claim under Illinois law.

We help clients evaluate whether they have a strong case, what damages may be available, and whether litigation or negotiated resolution makes more business sense before filing anything in court.

Mechanic’s Lien Claims

Illinois has strict deadlines and procedural requirements for mechanic’s liens. Contractors, subcontractors, and material suppliers who go unpaid on commercial construction projects have the right to place a lien on the property — but only if they follow the Illinois Mechanics Lien Act precisely.

We assist small businesses and contractors with:

• Filing and perfecting mechanic’s liens on commercial properties in Illinois
• Defending against mechanic’s lien claims asserted against your property
• Enforcing lien rights through litigation when payment is refused
• Lien waivers — reviewing what you’re signing before you give up your rights

Easement and Title Disputes

Easement conflicts and title defects can cloud ownership, interfere with development plans, or expose your business to liability you didn’t anticipate. Common disputes in Illinois include access easements across adjoining parcels, disputes over the scope of recorded easements, encroachments, and title insurance claims following a closing.

We help businesses and property owners understand their legal position, assert their rights, and resolve these disputes — through negotiation, quiet title actions, or other Illinois court proceedings as appropriate.

Commercial Real Estate Contract and Closing Disputes

Problems discovered after closing — undisclosed defects, survey errors, title issues that weren’t caught, or disputes between buyers and sellers over earnest money — require prompt legal attention. We represent buyers and sellers of commercial property in post-closing disputes and help clients understand their options under Illinois law.

Why Commercial Real Estate Disputes Demand an Attorney Early

Illinois commercial real estate law has hard deadlines that can permanently affect your legal rights:

• Mechanic’s lien deadlines: Under the Illinois Mechanics Lien Act, original contractors generally must record a lien claim within 4 months of their last work; subcontractors have 2 months. Missing these deadlines can eliminate your right to lien entirely.
• Statute of limitations: Breach of written contract claims in Illinois are generally subject to a 10-year limitations period, but other claims — fraud, negligence — have shorter windows. Don’t assume you have time.
• Notice requirements: Many commercial leases require written notice of disputes within specific timeframes. Failing to provide notice can waive your rights under the lease.

If you’re involved in a commercial real estate dispute in Chicago or elsewhere in Illinois, the earlier you get legal counsel involved, the more options you have.

Our Approach: Litigation When Necessary, Resolution When Possible

Litigation is expensive and disruptive — for businesses, especially. Our approach is to assess your situation honestly, tell you what your legal position actually looks like, and recommend the path that protects your interests most effectively. Sometimes that means filing in Cook County or another Illinois court. Often it means leveraging the threat of litigation to negotiate a better outcome.

We don’t manufacture disputes or encourage litigation for its own sake. We help you make informed decisions about when to fight and when to resolve.

Frequently Asked Questions

How do I sue over a commercial real estate contract in Illinois?

To bring a breach of contract claim involving commercial real estate in Illinois, you generally need a valid written contract, a clear breach by the other party, and demonstrable damages. Depending on the amount at issue, cases may be filed in the Illinois Circuit Court (including Cook County courts). An attorney can evaluate your specific facts, identify the correct court and procedure, and advise on realistic outcomes before you commit to litigation.

Can a small business file a mechanic’s lien in Illinois?

Yes. Illinois law allows contractors, subcontractors, and material suppliers — including small businesses — to assert mechanic’s liens against commercial property when they’ve provided labor or materials and haven’t been paid. The process is technical and deadline-driven. Working with an attorney early protects your lien rights.

What is the difference between commercial and residential real estate litigation?

Commercial real estate litigation is governed by different statutory schemes and involves different remedies than residential disputes. Illinois consumer protection laws that apply to residential transactions often don’t apply to commercial deals. Commercial leases, easements, and contracts are typically negotiated between sophisticated parties, which affects how courts interpret ambiguous terms.

Does Fitter Law handle real estate litigation on a flat-fee basis?

Litigation matters are generally handled on a project or hourly basis rather than a flat monthly subscription, depending on scope. We’ll discuss pricing transparently at your initial consultation so there are no surprises. Clients on our Outside Counsel or General Counsel plans receive preferred access and coordinated support across their legal needs.
