An established family relationship carries significant weight in the balancing.
A marriage or partnership lived over years with a shared household weighs heavily in the balancing exercise under section 9 BFA-VG. In such a case the public interest in an entry ban must be especially weighty for the interference with family life under Article 8 ECHR to remain proportionate. Document the relationship comprehensively.
Evidence such as a marriage certificate, a joint registration record and proof of everyday life strengthen the argument. Proportionality at the same time limits the permissible duration under section 53 FPG.
