A maintenance claim is to be refused, reduced or restricted in time to the extent that it would be grossly inequitable for the person obliged to be claimed on, even if the concerns of a child of the spouses entrusted to the person entitled in order to be cared for or brought up were observed, because
1. the marriage was of short duration; here, account is to be taken of the time in which the person entitled may demand maintenance for the care for or child-rearing of a child of the spouses under section 1570,
2. the person entitled lives in a stable long-term form of union,
3. the person entitled has committed a major criminal offence or a serious intentional minor offence against the person obliged or against a close relative of the person obliged,
4. the person entitled frivolously brought about their own indigence,
5. the person entitled frivolously disregarded serious property interests of the person obliged,
6. the person entitled, before the parties lived apart, for a long period grossly violated their duty to contribute to the family maintenance,
7. the person entitled is clearly responsible for manifestly serious misconduct towards the person obliged, or
8. there is another reason that is just as serious as the reasons set out in nos. 1 to 7.
