If you leave your partner, you can apply for child maintenance from them, to help with the costs of bringing up your children, although you may not wish to do this if it may cause you or your children further harm or distress. If you are afraid that your partner may threaten or ill treat you or your child if they are forced to pay child maintenance, it’s best to get advice before making a claim.
For impartial information and support with applying for child maintenance from your ex-partner, and the different options for you, go to the Gov.uk : Child Maintenance website.
If you and your ex-partner are unable to reach a ‘family-based agreement’ regarding maintenance payments, or you don’t know where your ex-partner is, you will need to contact the government’s Child Maintenance Service. The Child Maintenance Service has replaced the Child Support Agency and deals with all new applications for child maintenance payments. You do not have to pay the Child Maintenance Service application fee, which is currently £20, if you are a victim of domestic violence and abuse.
You could also contact Citizens Advice or Welsh Women’s Aid for help and support in dealing with your relationship breakdown and how this affects your finances.
