Can I claim maintenance for my children even if I remarry after divorce?

Yes, your remarriage generally doesn't affect your children's independent right to maintenance from their father — child maintenance is a separate entitlement belonging to the children themselves, distinct from any maintenance you as the former wife might have been claiming for your own support (which can, by contrast, sometimes be affected by your remarriage, depending on the specific terms of your divorce settlement or applicable law).

You, as the custodial parent, can continue to pursue and manage maintenance claims on your children's behalf even after your remarriage, since the underlying obligation on their biological father to support them continues regardless of your own marital status.

It's worth reviewing your original divorce settlement or maintenance order to check if it specifically addressed what happens to the children's maintenance in the event of your remarriage, just to confirm there's no unusual provision affecting this. If your former spouse tries to use your remarriage as a reason to stop paying child maintenance, that would generally not be a valid legal justification, and you can pursue enforcement through the court that originally granted the order.
