The AI checks your answers before you download

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

Sponsor Age Eligibility

This check verifies that the sponsor's date of birth (Question 5) indicates they are at least 18 years old at the time of application. This is a critical eligibility requirement for sponsoring a partner on de facto or prospective marriage grounds. If the sponsor is under 18, the application may be invalid unless specific exceptions (like a parent sponsoring on their behalf) apply, and the form processing should be flagged for manual review.

Sponsor Status Proof Requirement

This validation ensures that based on the citizenship/residence status selected in Question 8, the corresponding mandatory fields are completed. For example, if 'Australian citizen by grant' is selected, the 'Date of arrival in Australia' must be provided. This is crucial for verifying the sponsor's fundamental eligibility, and failure to provide the required details will delay processing until the necessary proof is submitted.

Passport Date Consistency

This check validates that the 'Date of expiry' in Question 10 is after the 'Date of issue'. This ensures the passport details provided are logical and not the result of a data entry error. An illogical date sequence would cast doubt on the validity of the provided document details and would require correction.

Relationship Status Completeness

This validation confirms that when a relationship status is selected in Question 21 (e.g., 'Married' or 'De facto'), the associated date and/or place fields are filled. Omitting these details leaves the application incomplete regarding the core nature of the relationship. The system should prevent submission or flag the section as incomplete if the required dependent information is missing.

Relationship Timeline Logic

This check compares the 'Date committed to a shared life' (Question 24) with the 'Date of marriage' or 'Date relationship began' (Question 21). The commitment date should logically precede or align with the formal start date of the marriage or de facto relationship. An illogical sequence, such as a commitment date after the marriage date, indicates a potential data entry error or a need for clarification and could trigger a more detailed review of the relationship evidence.

Previous Sponsorship 5-Year Limitation

If the sponsor indicates they have previously sponsored a partner (Question 29), this check verifies if the 'Date application lodged' for that sponsorship was within the last 5 years. Sponsoring another partner within this 5-year period is generally not permitted without compelling circumstances. A validation failure here would flag the application for a mandatory assessment of compelling circumstances, which could lead to refusal.

Common Mistakes in Completing 40SP

The ones the AI is built to catch.

Inconsistent or Inaccurate Relationship Dates
Applicants often provide inconsistent dates for when the relationship began (Q21) or when they committed to a shared life (Q24). This happens due to poor record-keeping or misunderstanding the distinction between dating and a de facto relationship. Inconsistencies between the sponsor's form and the applicant's form can raise red flags about the genuineness of the relationship, leading to further scrutiny or refusal. To avoid this, couples should agree on key dates and ensure they are recorded identically on all application forms and supporting statements.
Incomplete Disclosure of Previous Sponsorships
Sponsors fail to accurately complete Question 29 regarding previous partner sponsorships, often forgetting dates, outcomes, or the number of times they have sponsored. This is a critical integrity check, as there are strict limitations on how many partners one can sponsor and how frequently. Omitting or providing incorrect information can lead to an automatic refusal of the sponsorship and potentially a ban for providing misleading information. It is crucial to gather all historical records before filling out this section.
Failing to Provide Correct Proof of Citizenship or Residency
In Question 8, sponsors often select their status but fail to attach the specific type of proof required, such as providing a passport copy instead of a full birth certificate for an Australian citizen by birth. This mistake delays processing as the case officer must request the correct documentation. Sponsors must carefully read the instructions and provide certified copies of the exact documents listed for their specific status to ensure a smooth assessment.
Misunderstanding the 'Met in Person' Requirement
For Question 23, sponsors in relationships that began online may incorrectly tick 'Yes' to having met in person, even though the form explicitly states that meeting over the internet does not count. This is considered misleading information and can severely damage the credibility of the application. If you have only met online, you must tick 'No' and be truthful about the nature of your relationship's development.
Omitting or Poorly Explaining Periods of Separation
Sponsors often neglect to detail periods when they have lived apart from their partner in Question 25, fearing it will weaken their case. However, failing to declare these separations is worse, as it can be seen as an attempt to hide information. Any separation must be declared with a detailed, credible explanation (e.g., work assignments, visa restrictions, family emergencies) and supported by evidence to maintain the integrity of the application.
Inaccurate Declaration of Countries of Residence
In Question 38, sponsors frequently forget to list all countries where they have lived for a cumulative total of 12 months or more in the last 10 years. This is a critical error because it determines which foreign police certificates are mandatory for the application. Missing this information will halt the application process until the correct, and often slow-to-obtain, police certificates are provided, causing significant delays.
Non-Disclosure of Criminal History
When answering character questions (Q37, Q40), sponsors may be tempted to omit minor, old, or spent convictions, believing they are irrelevant. This is a serious mistake, as non-disclosure is treated more severely than the offense itself and will be discovered during mandatory police checks. Failing to declare any and all offenses, regardless of the outcome, can lead to refusal on character grounds for providing false or misleading information.
Incomplete or Missing Signatures in Declaration
The final declaration in Part K (Q52) requires four separate signatures for the Undertaking, Declaration, Acknowledgement, and Authorisation. It is very common for sponsors to miss one or more of these signatures or fail to date them correctly. An incompletely signed form is invalid and will be returned, causing significant processing delays. Each section must be read carefully and signed and dated individually.
Using Incorrect Name Variations
Sponsors often enter a nickname or a shortened version of their name in Question 2, instead of their full legal name as it appears on their passport. They may also forget to list all previous names or alternative spellings in Question 4. This creates identity verification issues and can delay the application. It is essential to use the exact name from official documents and declare all aliases or former names. AI-powered tools like Instafill.ai can help by cross-referencing data from uploaded documents to ensure names are entered correctly and consistently.
Failing to List All Migrating Dependents
In Part E, the sponsor must list every dependent family member who is included in the partner's visa application. A common oversight is forgetting to include a child or other dependent, creating a critical mismatch with the main applicant's Form 47SP. This discrepancy requires clarification and correction, halting the application's progress. To prevent this, the sponsor and applicant must communicate clearly to ensure both forms list the exact same migrating family members. Since this form is a non-fillable PDF, a tool like Instafill.ai can convert it into a fillable version, making it easier to complete accurately.

Who is required to fill out Form 40SP?

How do I submit this sponsorship form?

What key documents do I need to provide as a sponsor?

What should I do if my relationship with the applicant ends after I submit the form?
You are required to inform the Department of Immigration and Border Protection in writing if your relationship breaks down. Depending on the circumstances, your partner may still be eligible for a visa, for example, if family violence was involved.
