Lease Acceleration Clause
in Your Lease
What it actually means, what Indiana law says, what's specific to Indianapolis - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- No section we read in Ind. Code 32-31 states a landlord's duty to mitigate. Indiana's Court of Appeals supplies it in Nylen v. Park Doral Apartments, a 1989 case over a student apartment lease.
- Nylen says the landlord must use the diligence a reasonably prudent person would use to re-let the premises, if possible, and that "The obligation exists even if there is no mandatory re-letting clause in the lease."
- The same decision enforced a clause keeping evicted tenants liable for rent for the balance of the term. It affirmed future rent and late fees for the rest of the term because the manager had advertised the unit and lowered the rent to find a new tenant.
- Sandor Development Co. v. Reitmeyer puts the burden of proving a failure to mitigate on the abandoning tenant where the re-letting clause is not mandatory. Sandor involved shopping-center leases, which makes it the setting of that rule rather than a residential holding.
- § 32-31-3-13(2) lets a deposit pay rent due for premature termination, itemized in a notice due within 45 days under § 32-31-3-12(a). Neither decision was checked for later treatment, so read current Indiana case law and the current statute text yourself.
Understanding the Lease Acceleration Clause
An acceleration clause is the lease paragraph that turns the rest of your term into one bill. Miss a payment or move out early, and every month still to run is written up as payable now.
In Indianapolis the answer to that bill sits in Indiana case law rather than in a statute our record found. Nylen v. Park Doral Apartments says a landlord must use reasonable diligence to re-let the premises, if possible, whether or not the lease requires it.
The same decision upheld a clause keeping evicted tenants liable for rent for the rest of the term, on evidence that the landlord had advertised the unit and lowered the rent.
A second decision, Sandor Development Co. v. Reitmeyer, put the burden of proof on the tenant in a dispute over shopping-center leases. Indiana's deposit sections, § 32-31-3-13 and § 32-31-3-12, decide how much of an early break can come out of money you already paid.
What renters assume
An Indiana landlord who re-lets the unit is doing the tenant a favor, and a clause making the whole remaining term due is the end of the matter.
What is actually true
Nylen v. Park Doral Apartments says the landlord must use the diligence of a reasonably prudent person to re-let, if possible. It adds: "The obligation exists even if there is no mandatory re-letting clause in the lease." The same court enforced a balance-of-term clause in that case, on evidence that the landlord had advertised the unit and lowered the rent.
None of the 24 rows in the comparison on this page carries a figure; each is a short label. Indianapolis's reads Case law duty to re-let.
Fourteen of the 24 labels open with Mandatory, from Austin and Los Angeles through Minneapolis and Milwaukee. Four point the other way: Miami and Philadelphia read No duty to re-rent, Atlanta reads Likely no duty, and Kansas City reads No general duty; deposit rule.
Boston reads No statute; 93A limits, and Detroit reads Non-waivable by lease.
Four labels name case law: Indianapolis, Charlotte's Case law; tenant proves, and Denver and Columbus, which read No statute; case law. Indianapolis's label names the duty and not the burden. The Indiana decision on the burden in our record, Sandor, concerned shopping-center leases.
Plain English Version
If you leave early, an Indiana landlord has to try to re-rent, under a Court of Appeals decision rather than a statute our record found. That duty applies even when the lease does not require re-letting.
The catch is that the same court enforced a clause keeping evicted tenants liable for rent for the rest of the term, on evidence that the landlord had advertised the unit and lowered the rent. A shopping-center case put the burden of proving a weak effort on the tenant, and it is not a residential holding.
Rent Acceleration Clause Example - What the Wording Looks Like in Indianapolis, IN
The sample clause below is real lease language - a court quoted it word for word, and then ruled on it. What the judge decided is at the bottom of this block.
Find the equivalent paragraph in your own lease and read the two side by side. The wording will differ; the moving parts rarely do.
The Montana court quoted this lease paragraph in full, and the extract here ends one sentence early. That last sentence deals with late charges and interest running on an amount once it has been accelerated:
If any monthly installment under this agreement is not paid when due and remains unpaid after a date specified by a notice to Tenant, the entire principal rent amount owed for the full lease term shall at once become due and payable at the option of the Landlord and judgment may be had for all said amounts due. The foregoing provision shall not relieve the Landlord of its obligation to mitigate damages. In the event the rental premises is re-rented to another for full value prior to expiration of the lease term, Landlord shall file Notice of Partial Satisfaction of any judgment entered to the extent of the third party rental agreement.

Quoted from the published opinion in Summers v. Crestview Apartments, 2010 MT 164, 357 Mont. 123, 236 P.3d 586 (No. DA 09-0489). Judicial opinions are not subject to copyright; the lease language is reproduced in limited part for commentary under 17 U.S.C. § 107.
“the entire principal rent amount”
This is the figure the clause wants, and Indiana's residential case allowed a figure like it. In Nylen v. Park Doral Apartments the lease said eviction “shall not release tenant from liability for rent payment for the balance of the term of the lease”. The Court of Appeals held that upholding such a provision “is entirely consistent with existing Indiana case law”, and affirmed future rent and late fees for the rest of the term.
“at once become due and payable at”
The clause collapses the remaining months into one due date. Indiana's case law looks at what the landlord does across those months. Nylen says the doctrine of mitigation “creates an obligation on the part of the landlord” to use the diligence of a reasonably prudent person “to re-let the premises, if possible, in order to mitigate damages resulting from the tenant's breach of lease”.
“of its obligation to mitigate damages”
Here the clause keeps the duty, and in Indiana the lease does not have to. Nylen says “The obligation exists even if there is no mandatory re-letting clause in the lease.” Proof is a separate question, and the Indiana answer in our record comes from a shopping-center case. Where the re-letting clause is not mandatory, Sandor Development Co. v. Reitmeyer said “the burden of proof is on the abandoning tenant to show as a matter of defense that due diligence was not exercised, but the duty to mitigate damages still rests upon the landlord.”
“shall file Notice of Partial Satisfaction of”
This is the credit for re-letting, written as a court filing against the judgment. Indiana's deposit sections reach the same money from the other side. § 32-31-3-13(2) lets a deposit pay “all rent in arrearage under the rental agreement” and “rent due for premature termination of the rental agreement by the tenant”. § 32-31-3-12(a) requires the landlord to itemize deductions in a written notice delivered not more than 45 days after termination and delivery of possession.
The Montana Supreme Court struck this paragraph down, and its conclusion is one sentence: “Thus, we conclude that the accelerated rent provision is unconscionable and therefore unenforceable.” The tenants had moved out of their apartment on October 13, 2006, and Crestview answered with a Statement of Deductions from the Security Deposit charging rent through the end of the lease in June - $6,505.75 billed against a $2,170 deposit. Two reasons carried the court. Acceleration undermines the landlord's duty to mitigate and reduces the incentive to re-rent promptly, because a landlord already holding a judgment for the whole term has little reason to fill the unit. And Crestview drafted the lease while these tenants had no meaningful choice and no opportunity to negotiate any of it. The case was reversed and remanded, and two justices wrote separately - their objection being that the majority had gone as far as treating acceleration clauses as unenforceable in themselves. So read the holding narrowly, as the majority wrote it: this provision, in this residential lease, unconscionable and unenforceable. It is a Montana decision and it binds no other state's courts. What travels is the reasoning, and the reasoning is about mitigation - which is exactly the question the statute in your own city's decode answers.
One court, one lease, one state. That answer is not automatically yours, and your lease may be worded to land differently. Use this to know what to look for and what to ask - your state's tenant hotline or a local tenant attorney can answer it for your document.
Indiana Law on Lease Acceleration Clause
- Nylen is the residential case and it states the duty. The court said the doctrine of mitigation "creates an obligation on the part of the landlord" to use the diligence of a reasonably prudent person "to re-let the premises, if possible, in order to mitigate damages resulting from the tenant's breach of lease", and that "The obligation exists even if there is no mandatory re-letting clause in the lease." It also rejected the argument that the landlord should have let the tenants stay on paying two-thirds of the rent: "There is no authority for the proposition that a landlord must tolerate a breach of lease terms in order to mitigate its damages".
- Nylen enforced the clause that makes a lease break expensive. The lease said: "Eviction of tenant for a breach of lease agreement shall not release tenant from liability for rent payment for the balance of the term of the lease." The court held it "is entirely consistent with existing Indiana case law to uphold a lease provision which states that the lessee's liability for rent for the balance of the lease term will continue, notwithstanding an order of eviction", and affirmed an award of future rent and late fees for the rest of the term because the manager had advertised in the student newspaper and reduced the monthly rent to find a new tenant.
- The burden of proving a failure to mitigate sits with the tenant. In Sandor Development Co. v. Reitmeyer the court said that where the re-letting clause is not mandatory, "the burden of proof is on the abandoning tenant to show as a matter of defense that due diligence was not exercised, but the duty to mitigate damages still rests upon the landlord." Sandor involved shopping-center leases, and the landlord lost because it unreasonably refused a proposed assignee; that is the setting of the rule, not a residential holding.
- The security deposit can be applied to rent from an early break. Ind. Code § 32-31-3-13(2) lets a deposit pay "all rent in arrearage under the rental agreement" and "rent due for premature termination of the rental agreement by the tenant", and § 32-31-3-12(a) requires the landlord to itemize deductions in a written notice delivered not more than forty-five days after termination and delivery of possession. Check the current text of these sections and the later treatment of Nylen before relying on them.

Indiana's duty to mitigate is a rule of the courts. No section we read in Ind. Code 32-31 states it, and the Court of Appeals of Indiana supplies it in two published decisions.
The residential case is Nylen v. Park Doral Apartments, 535 N.E.2d 178 (Ind. Ct. App. 1989), decided March 20, 1989 over a student apartment lease. The court said the doctrine of mitigation "creates an obligation on the part of the landlord" to use the diligence of a reasonably prudent person "to re-let the premises, if possible, in order to mitigate damages resulting from the tenant's breach of lease".
It added: "The obligation exists even if there is no mandatory re-letting clause in the lease."
Nylen also enforced the clause that makes a break expensive. The lease said: "Eviction of tenant for a breach of lease agreement shall not release tenant from liability for rent payment for the balance of the term of the lease." The court held that upholding such a provision "is entirely consistent with existing Indiana case law", and affirmed future rent and late fees for the rest of the term.
The manager had advertised in the student newspaper and reduced the monthly rent to find a new tenant.
The court also rejected the tenants' argument that the landlord should have let them stay on paying two-thirds of the rent: "There is no authority for the proposition that a landlord must tolerate a breach of lease terms in order to mitigate its damages".
The burden comes from Sandor Development Co. v. Reitmeyer, 498 N.E.2d 1020 (Ind. Ct. App. 1986). Where the re-letting clause is not mandatory, "the burden of proof is on the abandoning tenant to show as a matter of defense that due diligence was not exercised, but the duty to mitigate damages still rests upon the landlord." Sandor involved shopping-center leases, and the landlord lost because it unreasonably refused a proposed assignee. That is the setting of the rule, not a residential holding.
The deposit is where Indiana's statutes meet an early break. Ind. Code § 32-31-3-13(2) lets a deposit pay "all rent in arrearage under the rental agreement" and "rent due for premature termination of the rental agreement by the tenant". § 32-31-3-12(a) requires the landlord to itemize deductions in a written notice delivered not more than 45 days after termination and delivery of possession.
Both decisions were read in full on CourtListener and were not checked against a citator for later treatment. Read current Indiana case law on Nylen and Sandor, and the current text of these sections on iga.in.gov, before relying on any of it.
Indiana Tenant Protections
The protection in our Indiana record is a duty the courts place on the landlord rather than a rule about the clause. Under Nylen v. Park Doral Apartments the landlord must use the diligence a reasonably prudent person would use to re-let the premises, if possible, and the obligation exists even where the lease has no mandatory re-letting clause. The same case shows the limit of that protection.
It enforced a clause keeping evicted tenants liable for rent for the balance of the term, and affirmed future rent and late fees, on evidence that the manager had advertised the unit and reduced the monthly rent. It also said a landlord need not tolerate a breach of lease terms in order to mitigate, rejecting the tenants' argument that they should have been allowed to stay on paying two-thirds of the rent.
On proof, Sandor Development Co. v. Reitmeyer put the burden on the abandoning tenant where the re-letting clause is not mandatory, while saying the duty still rests on the landlord. Sandor concerned shopping-center leases.
The deposit has statutory limits. § 32-31-3-13(2) lets it pay rent in arrearage and rent due for premature termination by the tenant, and § 32-31-3-12(a) requires deductions to be itemized in a written notice delivered not more than 45 days after termination and delivery of possession.

What's Specific to Indianapolis
Figures are the state rule, or the stronger city ordinance where one exists. Verify the current law for your own situation before relying on it.
For this question Indianapolis's own code is not where the answer sits, as far as our record reaches. Our record of the Revised Code of the Consolidated City and County was read on Municode's copy, codified through Ordinance No. 42, 2026.
It covers Chapter 582, Protection of Tenants' Rights (§ 582-101 through § 582-106), plus text searches of the code for "mitigate" and "acceleration". Those searches turned up sections on fire operations, hotels, stormwater, drainage, inspection fees and parking rather than leases.
No Indianapolis ordinance we read states a duty to mitigate or regulates rent acceleration.
The state code also speaks to local rules on this. Ind. Code § 32-31-1-20(c) bars a unit of local government from regulating leasing terms and conditions or the rights of the parties to a lease unless an act of the general assembly authorizes it, and declares any ordinance that does so void and unenforceable. § 36-1-3-8(a)(2) separately withholds from a unit "The power to prescribe the law governing civil actions between private persons."
That leaves an Indianapolis renter with the lease, two Court of Appeals decisions and the deposit sections. Read the acceleration paragraph for the figure it demands, then look for a clause like the one in Nylen, keeping you liable for rent for the balance of the term after an eviction.
Nylen turned on what the landlord did to re-let: advertisements for the unit and a lower monthly rent. Keep the date you returned the keys, copies of any listing for the unit, and the date a new tenant moved in.
If a landlord points to Sandor's burden of proof, note that it came from shopping-center leases.
Watch the deposit notice too. § 32-31-3-13(2) lets a deposit pay rent due for premature termination of the rental agreement by the tenant. § 32-31-3-12(a) requires each deduction to be itemized in a written notice delivered not more than 45 days after termination and delivery of possession.
For an Indianapolis early break, read things in this order:
- The acceleration paragraph, and the figure it names.
- Any clause keeping you liable for rent after an eviction.
- The itemized deposit notice, against § 32-31-3-13(2) and the 45-day deadline in § 32-31-3-12(a).
- Your own notes on what happened to the unit after you left.
Neither decision was checked against a citator for later treatment, so check current Indiana case law. An Indianapolis tenant lawyer or legal aid office can read your clause and the deposit notice with you before you agree to any figure.
Nylen v. Park Doral Apartments enforced that clause, for rent for the balance of the term, on evidence that the landlord had advertised the unit and lowered the rent.
Nylen's duty is to use the diligence of a reasonably prudent person to re-let, if possible. Listings, dates and a new tenant's move-in show whether that happened.
§ 32-31-3-12(a) requires deductions to be itemized in a written notice delivered not more than 45 days after termination and delivery of possession.
Nylen says the obligation to re-let "exists even if there is no mandatory re-letting clause in the lease". Our Indiana record holds no decision on a residential lease that waives the duty outright.

Red Flags to Watch Out For
-
A balance-of-term clause after eviction
Nylen v. Park Doral Apartments enforced a clause keeping evicted tenants liable for rent for the balance of the term. The landlord's advertising and lower rent were the evidence behind that award.
-
The whole term billed with no re-letting effort
Under Nylen the landlord must use the diligence of a reasonably prudent person to re-let, if possible. A bill for every remaining month with no sign of a listing or a new tenant deserves a question.
-
A shopping-center case quoted as settled
Sandor Development Co. v. Reitmeyer put the burden of proof on the abandoning tenant in a dispute over shopping-center leases. That is the setting of the rule, not a residential holding.
-
A late or unitemized deposit notice
§ 32-31-3-12(a) requires deductions to be itemized in a written notice delivered not more than 45 days after termination and delivery of possession.
-
Re-letting written as the landlord's free choice
Nylen says the obligation "exists even if there is no mandatory re-letting clause in the lease." Wording that makes re-letting optional deserves a second read.
Your Rights as a Indianapolis Tenant
-
A landlord who must try to re-let
Under Nylen v. Park Doral Apartments the landlord must use the diligence of a reasonably prudent person to re-let the premises, if possible, to mitigate damages from the tenant's breach.
-
A duty the lease does not have to state
Nylen says "The obligation exists even if there is no mandatory re-letting clause in the lease."
-
An itemized deposit notice
§ 32-31-3-12(a) requires deductions in a written notice delivered not more than 45 days after termination and delivery of possession.
-
The duty stays with the landlord
Even Sandor Development Co. v. Reitmeyer, a shopping-center case that put the burden of proof on the tenant, said "the duty to mitigate damages still rests upon the landlord."
What To Do - Step by Step
Find the acceleration paragraph
Note the figure it demands and the event that triggers it. Then look for a clause, like Nylen's, keeping you liable for rent for the balance of the term after an eviction.
Return the keys in a way you can prove
A dated handover, a photograph of the empty unit and a written note of the return date fix when the landlord's chance to re-let began.
Collect evidence of the re-letting effort
Nylen turned on advertisements and a lower monthly rent. Save listings for the unit, messages from the landlord and the date a new tenant moved in.
Check the deposit notice
Under § 32-31-3-12(a) it must itemize deductions and arrive not more than 45 days after termination and delivery of possession. Compare each line with § 32-31-3-13(2).
Check the code and the case law today
Our record of the Indianapolis code runs through Ordinance No. 42, 2026. Neither Nylen nor Sandor, the shopping-center case, was checked for later treatment, so read current Indiana case law yourself.
Get local advice before you agree to a figure
Take the lease, the deposit notice and your evidence to an Indianapolis tenant lawyer or legal aid office, and ask how Sandor's shopping-center setting bears on a home lease.
