An assignment of a lease in Florida transfers your entire remaining interest in the rental to a new tenant, who takes over your rights and obligations for the rest of the term. In most cases your landlord has to approve the transfer in writing, and even after the new tenant moves in, you can still be chased for unpaid rent unless the landlord formally releases you. Doing this right is mostly about two documents: the assignment itself, and a separate release.
Does Your Landlord Have to Approve It
Start with the lease. Look for a clause titled something like “Assignment and Subletting” or “Transfer of Interest.” Most Florida leases, and nearly all commercial ones, prohibit assignment without the landlord’s prior written consent. If your lease says nothing at all about assignment, Florida common law lets you transfer your interest freely, because the law generally favors a tenant’s ability to transfer a leasehold. Truly silent leases are uncommon, though. Assume consent is required until you’ve read the clause and confirmed otherwise.
When consent is required, the landlord cannot refuse arbitrarily. Florida courts have held that a blanket prohibition cannot be enforced in bad faith, even when the lease gives no further guidance on what “consent” means. In Fernandez v. Vazquez, a landlord refused to approve a replacement tenant and then offered the same space to that same tenant at $250 more per month. The court treated the refusal as a breach of the lease.1CaseMine. Fernandez v Vazquez
The same case identified the factors a landlord may legitimately weigh:
- Whether the proposed tenant can actually afford the rent and other obligations
- Whether the proposed use fits the building or surrounding tenants
- Whether the use would require significant alterations to the property
- Whether the proposed use is lawful
- Whether the type of occupancy is appropriate for the space
Refusing based on personal preference, minor inconvenience, or a desire to re-lease at a higher rent fails the good-faith test.1CaseMine. Fernandez v Vazquez If your landlord refuses improperly, you may have grounds to sue for damages or ask a court to compel consent. You carry the burden of proving the refusal was unreasonable, so put your request in writing, ask for the reasons in writing, and keep every response.
Assignment Is Not the Same as Subletting
These terms get used interchangeably, and they shouldn’t be. An assignment transfers everything: the full remaining term, all occupancy rights, and all obligations to the landlord. You keep no reversionary interest, meaning the property doesn’t come back to you at any point. A sublet carves out a portion of the lease, whether a part of the term, part of the space, or both, and you remain the landlord’s tenant. The subtenant pays you, not the landlord. If you only want someone to take a room or cover the summer months, you’re looking at a sublease, not an assignment, and your lease clause may treat the two differently.
Putting the Assignment in Writing
Florida’s statute of frauds requires any lease lasting longer than one year to be in writing and signed by the party being held to it, and the assignment of such a lease should follow the same rule.2Online Sunshine. Florida Statutes 725.01 – Promise to Pay Anothers Debt For shorter leases a written assignment is still the only practical option. Verbal arrangements about who owes rent, when the handover happens, and what condition the property is in produce disputes no one can prove.
A workable assignment agreement covers:
- Full legal names and contact information for you (the assignor), the new tenant (the assignee), and the landlord
- The complete property address
- A reference to the original lease by date, with a full copy attached so the assignee is bound by its terms
- The effective date on which the assignee takes over all rights and obligations
- A clear assumption clause stating that the assignee accepts all duties under the original lease, including rent, maintenance, and any other obligations
- A signature line for the landlord, which serves as written proof of consent
Florida law separately requires two subscribing witnesses for most transfers of interests in real property lasting more than a year, but the statute explicitly carves out leases and lease instruments, so your assignment does not need witnesses to be enforceable.3Florida Senate. Florida Statutes 689.01 – How Real Estate Conveyed Notarization never hurts in a commercial deal, but it isn’t required.
The practical sequence is to send the landlord a written request first, with full information on the proposed tenant (credit, references, income, business financials for a commercial space). Once the landlord signals willingness, you and the assignee sign the assignment agreement and present it to the landlord to countersign. Keep your fully executed copy indefinitely. Disputes about the original lease can surface years later.
The Security Deposit
Your original security deposit stays with the landlord when you assign. Florida law requires landlords to transfer deposits when the property itself is sold to a new owner, but there’s no parallel rule making the landlord refund your deposit mid-lease because you handed the lease off to someone else.4Florida Senate. Florida Statutes 83.49 – Deposit Money or Advance Rent
You have to recover the deposit from the incoming tenant directly. The assignee is stepping into a lease where a deposit already sits with the landlord, and if there’s damage after the assignment, the landlord will apply that money regardless of who originally paid it. Most assignors require the assignee to reimburse the deposit amount as part of the assignment deal. Write that into the agreement so no one is surprised later.
You Can Still Be Liable After the Assignment
This is where people get burned. Assigning your lease does not automatically end your obligation to pay rent. You signed the original lease and promised the landlord performance, and that promise survives the assignment. The new tenant becomes primarily responsible, and the landlord will chase them first. If the assignee stops paying, however, the landlord can come after you for every dollar owed through the end of the term.
Florida courts have applied this rule consistently. The original tenant’s obligations continue unless the original lease is replaced by a new agreement between the landlord and the assignee. Transferring possession and getting the landlord’s consent to the assignment doesn’t cut the cord by itself.
Getting a Full Release Through Novation
The one reliable way to end your liability is a novation: a written agreement among you, the new tenant, and the landlord that substitutes the assignee for you in the lease. It doesn’t just add a new responsible party. It removes you from the contract as though you had never signed.
A novation requires the landlord’s voluntary agreement, and landlords often resist, because keeping you on the hook gives them a backup if the new tenant defaults. Your leverage improves when the incoming tenant has strong finances, when you’re current on everything, and when the landlord values the relationship. The release has to be in writing. A verbal assurance that you’re “free and clear” is worth nothing if the assignee stops paying six months later. The document should state that the landlord releases you from all obligations under the original lease, effective on the assignment date.
Assigning Without Consent
If your lease requires approval and you assign anyway, the landlord has grounds to terminate. Florida’s residential landlord-tenant statute uses a notice-and-cure process for material lease violations: the landlord serves written notice describing the violation and gives the tenant seven days to fix it. If the violation can’t be cured, or if it repeats a prior written warning within twelve months, the landlord can terminate on seven days’ notice with no chance to correct it.5Florida Senate. Florida Statutes 83.56 – Termination of Rental Agreement
An unauthorized assignment can fall on either side of that line. A first-time violation might be curable (undo the arrangement within seven days). A repeat problem, or a history of warnings about unauthorized occupants, can skip the cure period entirely. The downside, for you and for the person who thought they were getting a place to live, isn’t worth the shortcut. Ask first.
