and how does the bank react in case of a separation regarding debtor release?
Is the bank interested in the notary's document?
1) a debtor release is always examined and is not guaranteed
2) if parts of the loan (here house) must also be taken out by the potential co-owner, then he should also have access to the house or its assets. Here, if the ownership shares or proportions are not known or are to be clarified afterwards based on the repayment status, a subordinate owner’s land charge can be registered in section 3, so that access always remains. This ensures that in the event of a separation, the owner cannot simply sell the house without clarifying the financial situation.
3) without real estate security, the problem is access to the property or acquired co-ownership shares, even though the loan may have been paid off over years, and without loan participation the problem may be that one party does not get the loan alone from the start, which can later be the main problem for debtor release.
3) the question here was rather not about the loan borrowers, but about the division of ownership shares, especially since with equal shares and 2 borrowers this problem always arises in case of separation. Tactically, nothing can be fixed in advance here.
4) the use of the property is compensated through the proportional share in the interest costs, while amortization and any value appreciation create assets in which one should already be secured in the land register.
As already described, nothing works without a lawyer/notary if it is to be secured individually according to the life situation, and for one person the way, the solution and security is the best and for someone else another way!
