A joint property purchase by unmarried partners should be checked before signing a property purchase contract. The key question is whether ownership shares, loan burden, own funds and later exit rules fit together.
The review must compare financing confirmation, proof of own funds, land register concept, agreement between buyers and draft contract. If these sources do not match, a general clause in the contract will often not solve the problem later.
This post does not replace a family-law agreement, but shows the purchase-contract points before signing. The decisive basis remains the specific contract, the current land register situation and the applicable Austrian legal framework.
