Frequently Asked Questions About OREA Form 100
OREA Form 100 has a Form Complexity Index of 72 out of 100, placing it in the complex complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.
For OREA Form 100 specifically, the score reflects 123 fillable fields across 6 pages, grouped into 49 sections, and 21 conditional fields that only apply depending on earlier answers, 5 tables or repeating lists. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.
In practical terms, a complex score means the form is demanding, with many fields, multiple pages and branching rules that are easy to get wrong. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes OREA Form 100 accurately in under a minute, with every field available for you to review before you download. See exactly how the Form Complexity Index is calculated.
This is a legally binding contract used in Ontario to formalize an offer from a buyer to a seller for a real estate property. It outlines all the terms and conditions of the sale, including price, dates, and other conditions.
This form is typically filled out by a real estate professional on behalf of a buyer making an offer on a property. Both the buyer and seller, along with their legal representatives, will use this form to complete the transaction.
The deposit is paid to the 'Deposit Holder' (usually the listing brokerage) and held in a trust account. It is applied toward the purchase price on the completion date and is returned to the buyer if the offer is not accepted or conditions are not met.
This is the deadline by which the person receiving the offer must accept it. The party making the offer cannot withdraw it during this time, but if it's not accepted by the specified time, the offer becomes void.
The 'Completion Date' is the closing day when ownership is transferred and the buyer gets the keys. The 'Requisition Date' is the deadline for the buyer's lawyer to complete title searches and raise any legal objections about the property's title.
Chattels are movable items (e.g., a refrigerator, washer) that you want included in the price, while fixtures are items attached to the home (e.g., a chandelier) that the seller plans to remove. Be very specific in these sections to avoid misunderstandings.
Schedule A is a critical part of the agreement where you detail how the balance of the purchase price will be paid. It is also used to add any other conditions to the offer, such as financing, home inspection, or the sale of the buyer's current property.
Under Ontario's Family Law Act, if the property being sold is a matrimonial home, the non-owning spouse must consent to the sale. This section ensures this legal requirement is met to provide a clear title to the buyer.
Section 7 specifies whether HST is included in the purchase price or is an additional cost on top of the price. This is particularly important for new or substantially renovated properties, and it must be clearly defined.
The form includes a section to provide your lawyer's name, address, email, and phone number. It's important to have this information ready so that all parties can communicate effectively through their legal representatives.
Yes, services like Instafill.ai use AI to auto-fill form fields accurately and save time, which is helpful for real estate professionals managing multiple documents. However, all legal agreements should be reviewed by a lawyer.
You can upload the PDF of Form 100 to Instafill.ai. The platform will make the document interactive, allowing you to easily click and type information into the correct fields, then save or share the completed form.
If you have a flat, non-fillable PDF, you can use a service like Instafill.ai to convert it into an interactive, fillable form. This allows you to complete the agreement digitally without needing to print it.
This clause details how prepaid expenses like property taxes and utility bills are prorated between the buyer and seller. The costs are divided so that the seller is responsible up to the completion day, and the buyer is responsible from that day forward.
Compliance OREA Form 100
Validation Checks by Instafill.ai
1
Validate Date Sequence Integrity
This check ensures that all key dates in the agreement follow a logical chronological order: Agreement Date <= Irrevocability Date <= Requisition Date < Completion Date. This is critical for establishing a valid and enforceable timeline for the contract. A failure indicates a temporal inconsistency that could void the agreement or lead to legal disputes over deadlines.
2
Ensures Deposit is Less Than Purchase Price
This validation confirms that the 'Deposit Amount' is numerically less than the total 'Purchase Price'. A deposit is a partial payment, not the full amount, so it cannot logically equal or exceed the purchase price. If this check fails, it indicates a significant data entry error that misrepresents the financial terms of the agreement.
3
Completion Date Must Be in the Future
This check verifies that the 'Completion Date' is a future date relative to the 'Agreement Date'. The closing of a real estate transaction cannot happen in the past. This validation prevents impossible or erroneous dates that would make the contract's performance timeline invalid from the outset.
4
Irrevocability Period Validity
This validation ensures the 'Irrevocability' date and time are set after the agreement is dated but before the 'Completion Date'. This period defines a binding window for acceptance. An invalid period (e.g., a date in the past) would render the offer immediately void or create ambiguity about its status, preventing a valid acceptance.
5
Buyer and Seller Full Legal Name Completeness
This check ensures that the 'Buyer' and 'Seller' name fields are not empty. A valid contract requires the clear identification of all parties involved using their full legal names. Failure to provide these names makes the agreement unenforceable as it's unclear who is bound by its terms.
6
Mandatory HST Clause Selection
This validation verifies that one of the two options ('included in' or 'in addition to') has been selected for the Harmonized Sales Tax (HST) clause. This term has a significant financial impact on the final amount payable and must be explicitly defined. An omission creates ambiguity over the true purchase price and can lead to major disputes at closing.
7
Requisition Date Precedes Completion Date
This check confirms that the 'Requisition Date' (for title search) occurs before the 'Completion Date'. The buyer's lawyer needs sufficient time between these dates to examine the title and address any potential issues before the transaction closes. An invalid order of dates makes it impossible to follow the contractual procedure for title examination.
8
Conditional Spousal Consent Completeness
This validation checks that if the 'Spouse' signature field is filled, then the corresponding 'Witness' and 'Date' fields for the spousal consent are also completed. The Family Law Act requires this consent for matrimonial homes, and incomplete execution can invalidate the sale. This check ensures all required elements for a valid consent are present if the section is used.
9
Confirmation of Acceptance Date Logic
This check ensures the 'Confirmation of Acceptance' date falls on or after the 'Agreement Date' and no later than the 'Irrevocability' deadline. This confirms the agreement was accepted by all parties within the legally binding offer period. An acceptance outside this window is not valid and does not create a binding contract.
10
Validate Contact Information Format
This check verifies that any provided email addresses and fax numbers in the 'Notices' section adhere to standard formats (e.g., '[email protected]' for email). Proper formatting is essential because these contacts are legally designated for the delivery of important notices. An invalid format could result in failed communication and disputes over whether notice was properly given or received.
11
Irrevocable Party Specification
This validation ensures the 'Irrevocable by' field is populated with either 'Seller' or 'Buyer'. It is essential to identify which party is making the binding offer that cannot be revoked for the specified period. Omitting this information creates ambiguity about who is bound by the offer's terms, potentially rendering it invalid.
12
Deposit Holder Name Presence
This check verifies that the name of the 'Deposit Holder' to whom the deposit cheque is payable has been entered. This is a critical detail for financial processing and ensuring the deposit is held in trust by the correct, legally designated entity. A missing name would prevent the buyer from correctly issuing the deposit and fulfilling their contractual obligation.
13
Required Initials Completeness
This validation scans the document to ensure all mandatory initial fields (e.g., next to Completion Date, Insurance clause) have been filled by both Buyer and Seller. Initials signify that the parties have read and acknowledged key clauses and pages. Missing initials can create doubt about whether the parties agreed to specific terms, weakening the enforceability of those sections.
14
Purchase Price and Deposit Numeric Validation
This check ensures that the 'Purchase Price' and 'Deposit' fields contain only valid numeric characters and currency symbols. These fields form the financial basis of the entire agreement, and must be clear, unambiguous numerical values. Non-numeric or improperly formatted entries would make the core financial terms void for uncertainty.
Common Mistakes in Completing OREA Form 100
This mistake occurs when buyers or sellers use nicknames, common names, or omit middle names instead of their full legal names as they appear on government identification and property title documents. This can create significant issues during the title transfer process and with mortgage financing applications, as names must match perfectly across all legal documents. To avoid this, always verify and enter the full legal names of all parties involved; AI-powered tools like Instafill.ai can help by storing and accurately populating this information consistently across all required fields.
Parties often correctly fill in the civic address but struggle with the lengthy and complex legal description, leading to transcription errors or omissions. The legal description, not the street address, is what legally defines the property being transferred. An error here can lead to a void contract, disputes over property boundaries, or even the transfer of the wrong parcel of land, causing catastrophic closing delays. This information should be copied verbatim from the current owner's deed or a recent survey, a task that can be automated and validated to prevent errors.
The deposit section requires multiple precise details: the amount, the timing (e.g., 'Upon Acceptance'), and the payee (the 'Deposit Holder'). People often leave these fields vague or enter incorrect information, such as the wrong brokerage name. This can invalidate the offer, cause the buyer to lose the property to a competing offer, or result in the deposit being sent to the wrong entity. To prevent this, clearly define the deposit amount, the 24-hour delivery window for 'Upon Acceptance', and the exact legal name of the listing brokerage's trust.
This is one of the most common sources of post-closing disputes. Parties use generic terms like 'appliances' or 'window coverings' instead of being specific, leading to disagreements over what was included. A seller might replace a high-end stove with a basic model, or a buyer might be surprised to find the custom drapes are gone. To avoid this, list every included chattel and excluded fixture with as much detail as possible (e.g., 'Samsung stainless steel refrigerator Model #...').
Sellers often forget they are renting equipment like hot water tanks, furnaces, or water softeners, as the payments are often bundled with utility bills. Failure to disclose these items in Section 6 means the seller is in breach of the agreement, as they cannot provide clear title to the item. This can force the seller to buy out the contract at a high cost or lead to the buyer unexpectedly inheriting a multi-year rental contract and monthly payments. Sellers must review their bills to identify and list all such items.
An offer is irrevocable for a specific period, and errors in setting this time are common. Parties may set a deadline that is too short for a proper response, causing the offer to expire, or forget to specify 'a.m.' or 'p.m.', creating ambiguity. This can lead to missed opportunities or disputes over when the offer officially expired. Always set a clear, specific date and time that is reasonable for all parties to review, sign, and return the document.
This agreement requires buyers and sellers to initial each page, signifying they have reviewed and accepted its terms. It is easy to miss an initial box when flipping through a multi-page document. A missing initial can create a legal vulnerability, as the other party could later claim that the terms on the uninitialed page were not agreed to, potentially jeopardizing the entire contract. A thorough final review is crucial, and digital form-filling platforms can often highlight all required initial and signature fields to ensure none are missed.
Under Ontario's Family Law Act, if the property is a matrimonial home, the non-titled spouse must consent to the sale, even if they are not on the title. Sellers often misunderstand this requirement or forget to have their spouse sign, especially if they are separated. Failure to obtain this consent makes the Agreement of Purchase and Sale unenforceable and can cause the entire transaction to collapse at the last minute, leading to significant legal and financial consequences.
The agreement often relies on attached schedules (like Schedule A for payment details) to include additional terms, conditions, or financing information. Common mistakes include forgetting to attach the schedule, failing to reference it in the main agreement, or not having all parties initial the schedule itself. This can render the conditions within the schedule void and unenforceable, meaning critical components of the deal, like a financing condition, may not be legally part of the contract.
Section 7 requires the parties to specify if HST is 'included in' or 'in addition to' the purchase price. This is often misunderstood, particularly for new homes, substantially renovated properties, or properties with some commercial use. An incorrect selection can result in a surprise tax bill amounting to tens of thousands of dollars for either the buyer or the seller. It is critical to get legal or accounting advice on the property's HST status before completing this section.
