One person brings more savings, the other can later contribute a larger share of the running costs. When buying an apartment together, this does not automatically result in a corresponding division of registered ownership. Especially in Austria, it is therefore important to clarify early on which form of ownership exists and which additional agreement is intended to document the financial contributions in a verifiable way.

The owners' partnership has its own framework

The official Austrian information explains that two natural persons establish an owners' partnership when jointly acquiring an apartment ownership object. They each hold half of the required minimum share, regardless of how much they contribute to the purchase price. A different allocation of these connected shares in the ratio of two thirds to one third is not provided for in this form. [PARTNER]

This statement refers to the specifically described owners' partnership. It is not a blanket description of every form of joint property ownership or every corporate solution. Therefore clarify before financing which form is actually envisaged for your project. An example about a differently held plot of land should not be transferred uncritically to the joint apartment purchase.

Record contributions fully and honestly

Our editorial recommendation: Draw up an overview of which funds each person can actually provide in time. Separate own equity, a genuine gift, a repayable family loan and merely expected funds. What is visible on a bank statement does not yet explain the origin or any possible repayment obligation. These differences can be important for internal agreements and the bank.

Also note which acquisition and preparatory costs are to be paid from which money. A contribution towards the kitchen is not automatically the same type of payment as own funds for the purchase price. The recording should not create unexamined claims for compensation. It gives the advising professional an understandable basis for the legal structuring.

Discuss ownership share and loan obligation separately

Which obligation you take on towards a bank results from the specific loan agreement and its securities. A private arrangement between the purchasing persons does not change this obligation simply by existing. Have it clearly explained to you who is the borrower, which securities are provided and what consequences can arise in the event of missed payments.

Example, fictional: Person A pays 90.000 Euro of own funds, Person B 30.000 Euro. Both wish to acquire apartment ownership together in the described partnership. The deposit list can document the differing contributions, but does not of itself change the intended half shares. The parties therefore clarify before the purchase whether and how the difference should be regulated internally. This article does not propose any unexamined contractual clause for that purpose.

Discuss changes while no dispute exists

Preparation includes questions about later sale, separation or a prolonged change in income. It is not about predicting these events. You want to know how a decision will be made and how a cash flow could be traced. Therefore note which questions you have answered together and which legal arrangements are still open.

A second fictional example: One person intends to work less in a few years. Today's affordability, however, is based on both full incomes. This change of plan belongs in the financing considerations and, if necessary, in the design of the internal task allocation. A verbal intention is not yet a reliable payment plan for the future.

Do not split decisions between different specialists without linking them

The bank, contract drafting and, where applicable, tax advice consider different parts of the project. Ensure that relevant changes to equity, participants or use are communicated to the respective reviews. Only the necessary information should be passed on. An internally intended compensation payment can be important for contract drafting, even if it did not appear in an initial financing discussion.

Keep the agreed status together with the evidence. Mark later changes as a new version. That way you can see at a later decision whether it still rests on the same financial basis.

The helpful starting point is a clear separation: Which ownership is created, which money does each person bring and which obligation do they take on externally? Only then can a suitable individual agreement be drawn up. For legal consequences, particularly in the event of separation or death, qualified individual advice is required.
