However, I would internally declare the gifts from the parents within the family as private interest-free loans, which would then have to be repaid if a separation and later payout is planned.
Gifts and inheritances are regularly not considered in the equalization of accrued gains. In my opinion, the respective parents should pay close attention to whom they give gifts (Are there separate accounts? The gift should then be transferred specifically with the appropriate comment.) Of course, the parents can, if they want, give gifts to the spouses in equal parts or also specifically to the child-in-law ;-). (In my case, my parents clearly said the gift was "for both of us". Whether they were aware of the significance of this statement, I do not know. It is not about large amounts with us anyway, so it doesn’t matter. Oh yes, we definitely don’t think about separation anyway :D )
At the time of the marriage, my wife brought about €65,000 into the marriage. I brought nothing.
Congratulations, by the way :-)!
How do you now do the land register entry most fairly
No idea, but in the event of a separation -- if nothing else is agreed upon -- an equalization of accrued gains will be carried out, and for that it does not matter how you are listed in the land register. I would therefore choose 50:50.
