Art. 137 Abs. 3, Art. 138 Abs. 3 and Art. 142 ZGB; reconciliation during divorce proceedings: a written reconciliation declaration is presumed voluntary when the spouses thereafter resume marital sexual relations. Such reconciliation extinguishes reliance on adultery and mistreatment as divorce grounds, but does not per se bar a claim based on continuing marital breakdown. Forgiveness does not retroactively erase fault as a cause of the breakdown; however, reconciliation is ordinarily a decisive indication that the breakdown is not so deep that continuation of the marital union can no longer be required (consid. 1).
