Unlike cases involving married couples in a divorce, financial settlements for unmarried couples are only applied to very rare cases, and limited in scope. You have no right, by default, to claim a share of your ex-partner’s assets, their pensions, or property - unless you can prove a beneficial interest.
Claims for child maintenance must be made through the Child Maintenance Service if your case is eligible, but their amount can be topped up by the court if the non-resident’s parent’s income is over £3,000pw. They may also oversee claims for child provisions outside of the scope of the Child Maintenance Service, which are regulated by the Children Act 1989.
