In essence, the partner who has acquired the larger entitlements must give half of the difference to the other partner.
A man had state pension entitlements of 200 Euro before the marriage. During the marriage, these grew to 500 Euro. He also made private provisions during this time, acquiring further entitlements of 200 Euro. The woman already had state pension entitlements of 150 Euro before the marriage. During the marriage, these increased to 300 Euro. She also has company pension provisions, with entitlements of 200 Euro acquired during the marriage.
The man must pay his former wife 150 Euro from the state pension (500 – 200 = 300 : 2 = 150) and 100 Euro from the private pension through the pension rights adjustment. He receives 75 Euro from his ex-wife's state pension (300 – 150 = 150 : 2 = 75) and another 100 Euro from the company pension.
During the marriage, the man acquired entitlements of 175 Euro, while his wife acquired over 250 Euro. He must therefore balance the difference of 75 Euro.
