The AI checks your answers before you download

12 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Ensures Property Identifier is Provided

This check verifies that the 'Property Identifier' field is not empty. The identifier is essential for linking this addendum to a specific property and its primary lease agreement. Without it, the document is legally ambiguous and cannot be correctly filed or enforced.

Confirms a Re-keying Option is Selected

This validation ensures that at least one of the two re-keying options (A: Owner pays or B: Tenant pays) has been checked. The choice of who bears the expense of re-keying is the central purpose of this addendum. If no option is selected, the form is incomplete and fails to document the agreement.

Enforces Mutually Exclusive Re-keying Options

This check ensures that only one of the two re-keying options is selected. The options are mutually exclusive, as either the owner pays or the tenant pays. Selecting both creates a contradiction, making the agreement unclear and unenforceable, so the form must be corrected.

Validates Presence of at least one Owner Signature

This check confirms that at least one of the Owner Signature fields is filled. For the addendum to be legally binding on the property owner, their signature (or that of their authorized representative) is required. A form lacking an owner's signature is incomplete and invalid.

Validates Presence of at least one Tenant Signature

This validation verifies that at least one Tenant Signature field has been completed. The tenant's signature signifies their understanding and agreement to the terms, particularly if they are assuming the cost of re-keying. Without a tenant's signature, the addendum is not binding on them.

Ensures Owner Signature is Accompanied by a Date

This check confirms that if the primary 'Owner Signature' field is filled, the corresponding 'Owner Signature Date' field is also filled. A signature without a date can create legal disputes about when the agreement was executed. The form is considered incomplete if a signature is present but its date is missing.

Common Mistakes in Completing Keys and Re-Keying Addendum

The ones the AI is built to catch.

Entering an Incomplete Property Identifier

Users often enter a partial address, like '123 Main St,' instead of the full, legally required identifier including a unit number or parcel ID. This happens when the full details aren't readily available. This ambiguity can render the addendum unenforceable if the owner has multiple similar properties, leading to disputes. To avoid this, always copy the complete property identifier exactly as it appears on the primary lease agreement.

Improper Selection of Re-keying Option

A frequent error is either checking both re-keying options (A and B) or leaving both unchecked. This is typically due to haste or misunderstanding, but it creates a critical ambiguity about who is financially responsible for the re-keying. The consequence is almost always a dispute and delay on move-in day. The owner must carefully choose one, and only one, option to create a clear, binding agreement.

Failing to Obtain All Required Signatures

The form is often submitted with missing signatures, especially when there are multiple owners or tenants who are not all present at the same time. The addendum is not legally binding on any party who has not signed it, which can invalidate the entire agreement. To prevent this, ensure every individual listed as an 'Owner' or 'Tenant' on the main lease provides their signature in the designated spaces.

Signing in the Wrong Section

In their haste, tenants may accidentally sign on a line reserved for an owner, or vice versa. This simple clerical error invalidates the signature and can require the form to be voided and re-executed. Carefully reading the labels ('Owner Signature,' 'Tenant Signature') next to each line is crucial. Using a guided form-filling tool can also help direct each party to the correct signature field.

Missing or Inconsistent Signature Dates

Signatories often forget to date their signature, or different parties may use conflicting date formats or dates. An undated signature can be legally challenged, and inconsistent dates create confusion about when the agreement was finalized. Each person should enter the current date at the time of signing to ensure the contract's timeline is clear and legally sound. AI-powered tools like Instafill.ai can help by automatically formatting dates correctly.

Using an Invalid Electronic Signature

When filling a form digitally, some people simply type their name in a cursive font, mistakenly believing it's a valid signature. This is not a legally enforceable e-signature and can nullify the addendum. For digital execution, use a verified e-signature platform. If the form is a non-fillable PDF, tools like Instafill.ai can convert it into a fillable version that integrates with proper e-signature workflows.

Ignoring the 'Legally Binding Contract' Warning

Parties frequently sign without fully reading the document, including the explicit warning at the top that it is a legally binding contract. This leads to tenants or owners being surprised by the financial obligations they agreed to in the selected re-keying option. This misunderstanding causes disputes and erodes trust from the start of the lease. All parties must read the entire form and seek legal advice if any part is not understood.

Using an Outdated Version of the Form

People may inadvertently use an old version of the form found via an internet search instead of the current official one. The version date '(01-01-2026)' indicates that this form is periodically updated. Using an obsolete form may mean its terms are not compliant with current state laws, risking the unenforceability of the addendum. Always source forms directly from the Oklahoma Real Estate Commission or a trusted professional.

Unnecessary Use of All Tenant Signature Lines

When there is only one tenant, they might mistakenly try to fill or cross out the additional tenant signature lines. This stems from a misunderstanding that all fields must be completed. This clutters the document and can create confusion about who the actual parties to the agreement are. To maintain clarity, only use the number of signature lines that corresponds to the number of tenants on the lease and leave any extra lines blank.
