Is there a grace period in Wyoming?
No statutory grace period was found in the chapter cited above. That does not make a fee charged on day one automatically safe - a court still asks whether the fee is reasonable - but Wyoming does not set a waiting period by statute. Whatever grace you give should be written into the lease so both sides are working from the same date.
Does the fee have to be in the lease?
The Wyoming statute does not say so in terms, but a late fee is a contract term like any other: if the lease does not create it, there is nothing to enforce. Write the amount and the day it applies into the lease.
Charging it without getting it wrong
Most late-fee disputes are not about the amount. They are about the date the clock started, whether the fee was in the lease, and whether each payment was recorded against the right charge. Those are bookkeeping problems, and they are the ones that lose in court.
LandlordPro applies the grace period you set, charges the fee once, and records each payment against the oldest unpaid month first (that month's late fee when the payment covers it, then its rent), so the ledger shows where every dollar went. The rent roll shows exactly which day a charge landed and why, and the tenant sees the same breakdown in their portal.

Frequently asked questions
What is the maximum late fee a landlord can charge in Wyoming?
Wyoming does not set one by statute. Wyoming's Residential Rental Property Act contains no section addressing late fees, caps or grace periods.
How many days late before a landlord can charge a fee in Wyoming?
Wyoming sets no statutory grace period, so the lease governs. Put the number of days in writing.
Does a Wyoming late fee have to be in the lease?
The statute does not say so expressly, but a late fee is a contract term: if it is not in the lease there is nothing to enforce. Always put it in writing.
Can a landlord charge a late fee every month the rent stays unpaid in Wyoming?
Wyoming does not address repeat fees by statute. Compounding a fee month after month on the same unpaid rent is the kind of charge courts treat as a penalty, so it is a risk worth avoiding.
Is a late fee the same as interest in Wyoming?
No. A late fee is a one-off charge for the administrative cost of a late payment. Interest accrues over time and is regulated separately. Charging both on the same rent invites a challenge.
