Means of support
Mag. Mirela Saric, Attorney at Law
If the person who gave a declaration of liability for a residence title is no longer available, a private agreement replacing that person is generally not enough. The authority must examine whether a new or amended declaration meets the statutory requirements and whether the evidence still supports the specific residence purpose.
Section 2(1)(15) NAG defines a declaration of liability as an authenticated declaration with a validity period of at least five years. It covers accommodation, corresponding maintenance and certain costs that may arise for a public authority. The new obligor's financial capacity must be shown at the time of the declaration.
This article deals with changing the obligor during a specific NAG procedure or for a residence title already granted on this basis. It focuses on continued coverage, the new declaration, the right timing and the documents needed for the authority's review.
Check the change of obligor
What must be clarified when the obligor changes?
First identify the stage of the procedure and the documents available for the new obligor.

01 Question 1
When is the obligor meant to change?
All paths at a glance
Overview of all answers.
01
Do not assume an automatic replacement after the grant
A private agreement does not replace the authority's review. Ask the authority to assess the departure of the existing obligor and the proposed new declaration in writing. Until that position is clear, the existing declaration should not simply be treated as discharged.
02
Establish the actual timing of the change
Check whether the existing obligor is permanently leaving or whether documents are merely being submitted later. The procedure stage, validity of the declaration and reason for the change determine the legal assessment.
03
Assign the new declaration to the application
Submit the authenticated declaration together with evidence of identity, address, income and regular liabilities. The residence purpose must allow the use of a declaration of liability. Section 11(6) NAG requires an express basis for this at the relevant residence purpose.
04
Clarify validity and the transition expressly
Set out the start, validity period and scope of both declarations in a written submission. Section 2(1)(15) NAG requires a minimum validity period of five years. The relevant provisions do not provide for an automatic replacement of the obligor through a private agreement.
05
Document financial capacity before signing
Complete the new person's income and liability evidence. Under section 11(5) NAG, when a declaration of liability is used, only the part of income above the protected minimum is considered for financial capacity. The concrete assessment depends on the documented circumstances.
What changes when the obligor is replaced?
The declaration of liability is linked to the person who made it and whose financial capacity was documented. Section 2(1)(15) NAG refers to a declaration by a third party who covers accommodation and corresponding maintenance and accepts liability for specified costs. A private notice therefore does not alter the original declaration.
Sections 2 and 11 NAG do not contain a rule under which a new person automatically takes the place of the existing obligor. The authority must assess whether a new declaration is sufficient, which declaration applies to which period and what further documents are required.
The distinction from a general declaration of support matters. A declaration of liability can support evidence of accommodation or maintenance only where the specific residence purpose expressly permits it. The site's residence-title topics provide the wider framework. The article on the form, duration and risk of a NAG declaration of liability explains the general framework.
Which declaration must the authority review?
The residence purpose must be identified first. Section 11(6) NAG requires the relevant residence purpose to expressly state that one or more requirements may be evidenced with a declaration of liability under section 2(1)(15) NAG. A new declaration can only be assessed within that statutory framework.
The next questions concern form and content. The declaration must be authenticated by an Austrian notary or a domestic court and remain valid for at least five years. It must cover the statutory services and costs. The new person's financial capacity must be documented when the declaration is made.
The authority also examines which requirement the declaration is meant to prove. Section 11(2)(2) and (4) concern accommodation and protection against a financial burden on a public authority. A new declaration does not automatically replace the other requirements of the residence title.
How should the change be reported before the decision?
A change before the decision should be reported in writing without delay. The submission should state the residence purpose, file number, reason for the change, date on which the existing obligor leaves and details of the new obligor. This enables the authority to identify the changed facts and the new evidence package.
The new person should submit the authenticated declaration and current financial evidence together. Proof of identity, address, income and regular liabilities must form a consistent record. The article on documents for a residence application provides further guidance on organising the application file.
Until the authority assigns the new declaration, the application should not be treated as though the replacement were already accepted. Keep both declarations in the file. Contradictory dates, accommodation details or statements about financial support may lead to a request for further evidence.
What applies after the residence title is granted?
After the grant, the residence title and the declaration of liability must be kept separate. The card documents the residence title. It does not itself decide whether and to what extent an existing declaration continues to apply.
If the obligor later leaves, the decision, existing declaration and proposed new declaration should be reviewed together. The date may be decisive for the authority's assessment. A private agreement between the old and new person does not answer this question on its own.
The change of obligor should also be kept separate from the general assessment of sufficient means. Own income and regular liabilities involve their own review. The article on means of support, income and rent under the NAG covers that neighbouring issue.
Which documents does the new obligor need?
The documents should explain the change and the financial basis together. They generally include the new authenticated declaration, proof of identity, proof of address and current evidence of income and regular liabilities. The exact scope depends on the residence purpose and the financial situation.
The timing is particularly important. The submission should show which declaration is already in the file, from when the new person is meant to be liable and whether a transition period is asserted. Unclear dates make it harder to assess continued coverage.
Also plan how the submission will be made to the competent authority. The site's residence-title checklists help organise the basic documents. They do not replace the specific review of the change of obligor.
How do several obligors affect the replacement?
Section 2(6) NAG permits only one declaration of liability for an application for the grant or renewal of a residence title. If several people appear as obligors in that declaration, each is liable for the full amount jointly and severally. The authority therefore reviews one joint declaration, while each person may face the full external liability.
An internal agreement can distribute contributions or recourse between the participants. It does not change the external liability towards the public authority. When an obligor changes, specify whether a person is to leave a joint declaration, provide a new declaration or join a new one.
Preparing a declaration for several people is a separate focus. The article on several obligors and their documents covers the shared file, financial evidence and the distinction between external liability and internal arrangements.
Which mistakes can weaken coverage after a change?
A common mistake is assuming that a new person can take over the existing declaration informally. The declaration is tied to its authenticated form, minimum duration and proof of financial capacity. The new person must meet these requirements independently.
Uncoordinated dates are another problem. If the old and new declarations use different starting or ending dates, it remains unclear which coverage applies to which period. Submit both versions with a clear timeline.
Finally, changing the obligor must not be confused with replacing the residence-title procedure as a whole. Purpose, insurance, identity, accommodation and other requirements remain separate matters. Replace or supplement only the evidence function that the declaration is meant to provide.
Questions about changing a declaration of liability
Can another person simply take over the declaration of liability?
A private agreement is not sufficient by itself. The new person generally needs to provide an authenticated declaration and evidence of financial capacity. The authority must assign the new declaration to the residence purpose and procedure.
Does the existing person's liability end automatically when the obligor changes?
The relevant NAG provisions do not contain an automatic replacement rule for a change of obligor. Until the authority has assessed the change, the existing declaration should not be treated as discharged. The procedure stage, declarations and dates are decisive.
Which documents does the new obligor need?
The new authenticated declaration, proof of identity and address, and current evidence of income and regular liabilities are generally required. The exact documents depend on the residence purpose and individual circumstances.
Can a second declaration be submitted as a precaution?
Section 2(6) NAG provides for only one declaration of liability for an application for the grant or renewal of a residence title. Several people may appear as obligors in that one declaration. A second declaration should therefore not be added without checking the procedural situation.
Does a declaration of liability continue after the residence card expires?
Section 2(1)(15) NAG requires a validity period of at least five years. The minimum duration of the declaration and the validity of the residence card must therefore be considered separately. The consequences depend on the procedure and the wording of the declaration.
